5 Leftover Spaghetti Recipes for Delicious Weeknight Dinners!

In This Article

Turn last night’s pasta into tonight’s favorite meal with these leftover spaghetti recipes. Here are tasty family dinner ideas that make leftovers worth saving!!

Open your refrigerator, pull out that container of yesterday’s noodles, and imagine crisp Parmesan edges, bubbling cheese tucked inside sweet peppers, or a gingery coconut broth that smells wonderful before you even pick up a spoon.

These five leftover spaghetti recipes give you delicious reasons to look forward to round two, with enough variety to suit both plain noodles and pasta already wearing a little tomato sauce.

Apparently, accidentally cooking enough spaghetti for a small neighborhood can work in your favor!

Before You Start

All pasta measurements below refer to cooked, refrigerated spaghetti, measured before cutting.
For plain spaghetti, one loosely filled cup weighs roughly 140 g, although thickness and packing change that number; use weights when possible, and do not substitute these quantities with dry pasta.
Tomato-coated leftovers weigh more, so use cup measurements for those variations.
If plain noodles have stuck together, loosen them gently with your fingers or tongs.
For soup and skillet recipes, a tablespoon or two of liquid from your measured broth will help; for crispy cakes, keep noodles dry so you do not weaken your mixture.
Avoid forcing a solid clump apart with a fork unless you enjoy chasing spaghetti across your counter!
Use spaghetti refrigerated within two hours of cooking, or within one hour in temperatures above 90°F (32°C), and stored at 40°F (4°C) or colder.
Use refrigerated leftovers within three to four days and heat these dishes to 165°F (74°C) throughout.

Leftover Spaghetti Recipes

1. Lemon Parmesan Spaghetti Cakes with White Beans and Dill Yogurt

These little cakes have golden, crinkly spaghetti edges and soft centers flecked with scallions, lemon zest, and Parmesan, while mashed white beans help hold everything together without turning each bite into a bread-heavy fritter.

A spoonful of cool dill yogurt adds just enough tang to make you want another crisp corner immediately!

I would make these when you have plain noodles and want something you can put beside a crunchy salad for lunch. Keep some bean pieces visible when you mash, because those creamy little pockets are part of what makes these cakes interesting. Research link for the bean benefit.

Servings: 4, with 2 cakes each
Yield: 8 cakes
Best leftovers: Plain spaghetti or spaghetti lightly tossed with olive oil

Ingredients

3 cups cooked, chilled spaghetti, about 420 g
1 cup canned cannellini beans, about 170 g after rinsing and draining
2 large eggs
1/2 cup finely grated Parmesan, about 45 g
1/3 cup plain panko breadcrumbs, about 20 g, plus up to 2 tablespoons if needed
2 scallions, thinly sliced
1 teaspoon finely grated lemon zest
1/4 teaspoon garlic powder
1/4 teaspoon black pepper
1/4 teaspoon fine salt, optional if your pasta is already salty
3 tablespoons olive oil, divided
3/4 cup plain Greek yogurt, about 170 g
2 tablespoons finely chopped fresh dill
1 tablespoon fresh lemon juice
A small pinch of salt for yogurt sauce, to taste

How to Make It

Spread drained beans on a clean towel and pat them dry, then mash them in a large bowl until mostly broken down, with a few small pieces remaining. Snip spaghetti into roughly 1-inch lengths with kitchen scissors.

I strongly recommend doing this over your bowl, because shorter strands mix evenly and will not drag half your mixture along when you lift a spoonful.

Beat eggs into mashed beans, then stir in Parmesan, 1/3 cup panko, scallions, lemon zest, garlic powder, pepper, and optional salt before folding in spaghetti.

Refrigerate for 10 minutes so breadcrumbs can absorb moisture, using that time to stir yogurt, dill, lemon juice, and a small pinch of salt together in a separate bowl.

Check your chilled mixture by pressing a spoonful together: it should hold a soft mound, with no puddle of egg underneath. If it still feels loose, fold in 1 tablespoon extra panko, wait 2 minutes, and add another tablespoon only if needed.

Divide into eight equal portions and gently shape cakes about 3 1/2 inches across and 3/4 inch thick, pressing stray strands back into their edges.

Warm 1 1/2 tablespoons olive oil in a 12-inch nonstick skillet over medium heat, then add four cakes with a little space between them.

Cook for 4 to 5 minutes without moving them, until bottoms look deep golden and feel firm enough to lift with a wide spatula; don’t skip that undisturbed cooking time, because a proper crust makes flipping much less dramatic!

Turn carefully and cook for another 4 to 5 minutes, checking that centers reach 165°F (74°C). If outsides brown before middles are hot, reduce heat to medium-low and cook a little longer.

Transfer to a wire rack, add remaining oil, and repeat with your second batch, serving yogurt alongside so everyone can dip without softening those crisp edges.

Serving Suggestions

Serve two cakes per person with chopped cucumber, cherry tomatoes, and a squeeze of lemon, or place them over lightly dressed arugula for a lunch with plenty of crunch.

For smaller appetites, one cake makes a good side for a bowl of tomato soup; keep yogurt in a separate little dish so each bite gets as much tang as you like.

2. Smoky Spaghetti Stuffed Peppers with Black Beans and Corn

Sweet roasted peppers hold a tangle of smoky tomato spaghetti, creamy black beans, and little pops of corn beneath melted Monterey Jack.

Cutting peppers lengthwise gives you more browned cheese in every serving and makes filling them much easier than trying to lower spaghetti into a narrow pepper opening with surgical precision!

My pick here is a red or orange bell pepper, whose sweetness works particularly well with smoked paprika and lime. This recipe also gives lightly tomato-coated spaghetti a useful home, and you can adjust added marinara so your filling stays juicy without leaving a puddle on your plate.

Servings: 4, with 2 pepper halves each
Best leftovers: Plain spaghetti or spaghetti lightly coated in tomato sauce

Ingredients

4 large bell peppers, preferably red, orange, or yellow
2 tablespoons olive oil, divided
1/4 teaspoon fine salt, plus more only if needed
1/2 medium yellow onion, finely diced, about 1/2 cup or 75 g
2 garlic cloves, minced
1 teaspoon smoked paprika
1/2 teaspoon ground cumin
3 cups cooked spaghetti; about 420 g if plain
1 cup canned black beans, about 170 g after rinsing and draining
3/4 cup frozen corn, thawed and patted dry, about 110 g
3/4 cup thick marinara sauce for plain spaghetti; start with 1/4 cup if using tomato-coated spaghetti
1 cup shredded Monterey Jack, about 115 g, divided
1 tablespoon fresh lime juice
2 tablespoons chopped cilantro
1/4 cup plain Greek yogurt or sour cream, optional for serving

How to Make It

Heat your oven to 400°F (200°C) and line a 13-by-18-inch rimmed baking sheet with foil. Cut peppers lengthwise through their stems, remove seeds and pale ribs, and rub cut surfaces and skins with 1 tablespoon olive oil and 1/4 teaspoon salt.

Arrange cut-side down and roast for 18 to 20 minutes, until edges begin to wrinkle and flesh bends slightly when pressed with tongs.

While peppers roast, snip spaghetti into 2-inch lengths and warm remaining tablespoon oil in a large skillet over medium heat. Add onion and cook for 5 to 6 minutes, stirring occasionally until softened, then stir in garlic, smoked paprika, and cumin for 30 seconds, just until their fragrance rises without allowing garlic to brown.

Add beans, corn, spaghetti, and appropriate starting amount of marinara, then toss gently for 3 to 5 minutes. You want glossy strands that cling together when scooped, with no loose liquid collecting underneath; if tomato-coated noodles look dry, add more marinara 1 tablespoon at a time.

If filling looks watery, let it cook uncovered for another minute or two before taking your skillet off heat and stirring in lime juice and 1/2 cup cheese.

Turn roasted pepper halves cut-side up, taking care around escaping steam, and tip away any liquid gathered inside.

Divide spaghetti mixture among all eight halves, pressing lightly into their curves and making small mounds above their rims, then scatter remaining 1/2 cup cheese evenly over tops.

Return to your oven for 18 to 23 minutes, until cheese melts, pepper edges deepen in color, and filling reaches 165°F (74°C) in its center. If cheese colors faster than peppers soften, cover loosely with foil for remaining cooking time.

Rest for 5 minutes before adding cilantro and optional yogurt, because molten cheese is enthusiastic about introducing itself to your tongue!

Serving Suggestions

Place two halves on each plate with a crunchy cabbage slaw dressed with lime juice and a little olive oil. A few avocado slices are lovely alongside, particularly if you add hot sauce at your table, and extra lime wedges let everyone sharpen up that smoky tomato flavor to taste.

3. Ginger Coconut Chicken Soup with Leftover Spaghetti

Here, spaghetti becomes soft, slurpable noodles in a fragrant coconut broth with ginger, tender chicken, sweet carrot, and green ribbons of bok choy.

Red curry paste adds gentle chili warmth and aromatic depth, while lime juice keeps each spoonful lively enough that you will probably reach for another squeeze halfway through your bowl.

I would choose this recipe when leftover spaghetti has softened a little too much for frying into cakes, because those tender strands work nicely in broth.

Add pasta near the end and serve promptly, though, because fully cooked spaghetti does not need a long simmer to contemplate its second career!

Servings: 4 generous bowls
Best leftovers: Plain spaghetti without tomato, cheese, or cream sauce

Ingredients

1 tablespoon neutral oil, such as avocado or canola
1 small yellow onion, finely diced, about 1 cup or 120 g
2 tablespoons finely grated fresh ginger
3 garlic cloves, minced
1 tablespoon red curry paste; start with 1 to 2 teaspoons if your brand is very hot
4 cups reduced-sodium chicken broth, 960 ml
1 can light unsweetened coconut milk, 13.5 fluid ounces or about 400 ml
1 medium carrot, peeled and cut into thin matchsticks
3 cups chopped bok choy, about 200 g, stems and leaves kept separate
1 1/2 cups cooked shredded chicken, about 225 g
2 cups cooked plain spaghetti, about 280 g
1 tablespoon reduced-sodium soy sauce, plus more to taste
1 to 2 tablespoons fresh lime juice
1 teaspoon brown sugar, optional if needed to balance acidity
2 tablespoons chopped cilantro
Extra lime wedges, optional for serving

How to Make It

Warm oil in a 5-quart pot over medium heat and cook onion for 4 to 5 minutes, stirring until softened and translucent.

Add ginger and garlic for about 30 seconds, followed by curry paste for another 30 seconds, stirring constantly so those aromatic ingredients warm through without catching on your pot.

Pour in chicken broth and coconut milk, scraping up any curry paste from underneath, and bring to a lively simmer over medium-high heat, which should take about 5 to 7 minutes.

Reduce heat to medium-low, add carrot and bok choy stems, and simmer gently for 4 to 5 minutes, until carrots bend easily but still offer a little bite.

Snip spaghetti once or twice if you prefer shorter noodles, then add it with chicken and soy sauce. Stir gently to separate strands and simmer for 3 to 5 minutes, adding bok choy leaves during the final 2 minutes; pasta and chicken should be thoroughly hot, with chicken reaching 165°F (74°C).

If your noodles were already very soft, check them as soon as they heat through instead of automatically cooking for another full 5 minutes.

Take your pot off heat and stir in 1 tablespoon lime juice before tasting a spoonful that has cooled slightly. Add remaining lime for more brightness, a little extra soy sauce if broth tastes flat, or optional brown sugar if lime and curry paste together seem too sharp.

I would make these adjustments in small amounts, because a broth can move from beautifully balanced to an accidental salt lick surprisingly quickly!

Ladle into four bowls immediately, distributing noodles and chicken before adding remaining broth, then finish with cilantro.

Bring bowls straight to your table so spaghetti stays tender and broth remains plentiful, rather than letting noodles sit and absorb it while you finish another kitchen task.

Serving Suggestions

Serve with lime wedges and a small cucumber salad tossed with rice vinegar and a pinch of salt. This is a generous noodle soup, so extra bread is optional; for more crunch, scatter a spoonful of chopped roasted peanuts over each bowl if everyone eating can have them.

4. Creamy Dijon Mushroom Spaghetti with Crispy Rye Crumbs

Browned mushrooms, sweet softened leek, and a tangy Dijon cream sauce make leftover spaghetti taste rich and full-flavored, while buttery rye crumbs give every forkful a little crunch.

Fresh dill adds a gentle herbal finish that works especially well with mustard, so this has a different personality from a standard cream-and-cheese pasta.

I would use cremini mushrooms for their earthy flavor and full-fat sour cream for a smooth sauce.

Your most useful decision here is to brown mushrooms in two batches, because a crowded pan traps moisture, and mushrooms deserve better than being accidentally steamed into beige little sponges!

Servings: 4
Best leftovers: Plain spaghetti or spaghetti lightly tossed with butter

Ingredients

4 cups cooked spaghetti, about 560 g
2 tablespoons unsalted butter, divided
1 cup coarse fresh rye breadcrumbs, about 50 g; sourdough crumbs also work
2 tablespoons olive oil, divided
12 ounces cremini mushrooms, 340 g, wiped clean and cut into 1/4-inch slices
1 medium leek, white and light green parts thinly sliced, about 1 heaped cup or 100 g
2 garlic cloves, minced
1/2 teaspoon dried thyme
1 tablespoon all-purpose flour
1 1/4 cups reduced-sodium vegetable broth, 300 ml, plus up to 1/4 cup more if needed
1 1/2 tablespoons Dijon mustard
1/2 cup full-fat sour cream, about 120 g
1/4 teaspoon black pepper
Up to 1/4 teaspoon fine salt, only if needed
2 tablespoons chopped fresh dill or parsley

How to Make It

Rinse sliced leek thoroughly in a bowl of cool water, lifting pieces out so any grit stays behind, then drain and pat dry. Melt 1 tablespoon butter in a wide, deep 12-inch skillet over medium heat, add rye crumbs, and stir for 3 to 4 minutes until crisp and golden, transferring them immediately to a plate so residual heat does not darken them further.

Add 1 tablespoon olive oil to your skillet and raise heat to medium-high. Spread half your mushrooms in a single layer and leave them alone for about 2 minutes before stirring, then cook for another 3 minutes or so until browned and their released moisture has evaporated. Transfer to a bowl and repeat with remaining tablespoon oil and remaining mushrooms.

Reduce heat to medium, return all mushrooms to your skillet, and add remaining tablespoon butter and drained leek. Cook for 4 to 5 minutes until leek softens, then stir in garlic and thyme for 30 seconds.

Sprinkle flour evenly across vegetables and stir for 1 minute, making sure no dry patches remain before gradually pouring in broth and stirring in Dijon.

Bring sauce to a gentle simmer and cook for about 2 minutes, until slightly thickened, then add spaghetti and toss carefully for 3 to 5 minutes.

If noodles are tightly clumped, cover for 1 minute so steam loosens them, then separate gently with tongs; add extra broth 1 tablespoon at a time if sauce becomes too tight before pasta heats through.

Turn heat low, mix a few spoonfuls of hot sauce into sour cream in a small bowl, and stir that mixture back into your skillet. Heat gently until everything reaches 165°F (74°C), without bringing sauce to a hard boil, then add pepper, taste for salt, and fold in dill or parsley.

Don’t skip warming sour cream with a little sauce first, because that smaller temperature change helps it blend more smoothly!

Divide among four shallow bowls and scatter rye crumbs over each serving just before eating. Leave any extra crumbs at your table in a small dish, because someone will almost certainly decide their bowl needs another spoonful.

Serving Suggestions

Pair with lemon-dressed green beans or a crisp cucumber and radish salad, whose freshness balances that creamy mustard sauce.

A few thinly sliced cornichons on the side are especially good if you enjoy a sharper, deli-style contrast, but keep them separate so everyone can choose how tangy their meal becomes.

5. Roasted Pepper and Olive Spaghetti Quesadillas

These quesadillas tuck tomato-coated spaghetti, sweet roasted peppers, briny olives, and stretchy mozzarella inside golden flour tortillas, giving you crisp edges and a soft, cheesy middle.

Basil and Parmesan bring a familiar tomato-pasta flavor, while short spaghetti strands make each wedge easy to bite without pulling your entire dinner out in one ambitious mouthful!

My strongest recommendation is to drain and blot roasted peppers thoroughly, then use thick marinara sparingly.

Moisture is what separates a crisp quesadilla from a tortilla that folds over your hand like a damp napkin, so a little restraint here pays off in every crunchy bite.

Servings: 4, with 1 large folded quesadilla each
Yield: 12 wedges when each quesadilla is cut into 3 pieces
Best leftovers: Tomato-coated spaghetti, or plain spaghetti with added marinara

Ingredients

2 1/2 cups cooked spaghetti; about 350 g if plain
1/3 cup thick marinara sauce, about 80 g, if using plain spaghetti; omit if noodles are already well coated
1/2 cup jarred roasted red peppers, about 75 g after draining, blotted dry and finely chopped
1/4 cup sliced pitted black or green olives, about 35 g, drained
1/4 cup finely grated Parmesan, about 25 g
8 fresh basil leaves, thinly sliced
2 tablespoons water, only if needed while warming filling
4 large flour tortillas, about 10 inches across
2 cups shredded low-moisture mozzarella, about 225 g
4 teaspoons olive oil, divided
Extra warm marinara, optional for dipping

How to Make It

If you want to keep early batches warm, heat your oven to 200°F (95°C) and set a wire rack over a baking sheet. Snip spaghetti into 1- to 2-inch pieces, then combine with appropriate amount of marinara, roasted peppers, and olives in a nonstick skillet over medium-low heat.

Warm filling for 4 to 6 minutes, stirring gently and adding up to 2 tablespoons water only if strands are too stiff to separate, until it reaches 165°F (74°C).

Let any added water evaporate so no liquid pools under your spatula, then take off heat, stir in Parmesan and basil, and transfer to a shallow bowl for a few minutes while you wipe your skillet clean.

Lay one tortilla flat and sprinkle 1/4 cup mozzarella over one half, keeping a 1/2-inch border clear. Spread one-quarter of your spaghetti filling evenly across that cheese, then top with another 1/4 cup mozzarella and fold uncovered half over. Cheese on both sides helps hold filling against your tortilla, so I would resist putting it all in one thick layer underneath.

Heat 1 teaspoon olive oil in your skillet over medium-low heat and slide in your folded tortilla.

Cook for 2 to 3 minutes per side, pressing very gently with a spatula, until both surfaces have golden patches, mozzarella has melted, and center is hot throughout; check for 165°F (74°C). If tortilla browns before cheese melts, lower heat and give it another minute rather than turning your stove up.

Repeat with remaining tortillas, cheese, filling, and oil, transferring finished quesadillas to your oven rack in a single layer if needed.

Let each one rest for 1 to 2 minutes before cutting into three wedges, which gives cheese a moment to settle and makes it much less likely that your first slice will leave all its filling behind.

Serving Suggestions

Serve three wedges per person with a tomato and cucumber salad, plus a little warm marinara for dipping.

For a casual appetizer platter, cut each quesadilla into four smaller wedges and arrange them in a loose single layer; stacking traps steam and softens those carefully browned tortillas.
