Savory Instant Pot Chicken Spaghetti

My Tuesday evening routine was completely upended the day I discovered you could make spaghetti in a pressure cooker. The house was chaos—kids needing homework help, emails piling up, and absolutely zero desire to stand over a boiling pot of pasta for twenty minutes. This recipe saved dinner that night, and honestly, it has been on heavy rotation ever since that first miraculous attempt.

Last month, my sister came over for dinner and watched me make this with total skepticism. She is a traditional Italian cooking purist who believed pasta could only be cooked in heavily salted boiling water. After one bite of this tender, flavor-infused spaghetti, she asked for the recipe and bought an Instant Pot three days later. Sometimes convenience does not mean sacrificing quality.

Ingredients

• 2 large boneless skinless chicken breasts about 500g: Cutting into bite sized pieces helps them cook evenly and stay tender during pressure cooking
• 1 medium onion finely chopped: The onion foundation provides that essential savory base that mellows beautifully under pressure
• 3 cloves garlic minced: Garlic needs only seconds to bloom, so add it right at the end of sautéing to avoid bitterness
• 1 red bell pepper diced: This adds sweetness and color that balances the acidic tomatoes perfectly
• 1 can 400g crushed tomatoes: The crushed tomatoes create body without needing hours of reduction
• 2 tablespoons tomato paste: This concentrates the tomato flavor and helps thicken the sauce during cooking
• 250g uncooked spaghetti broken in half: Breaking the noodles helps them fit and cook evenly without clumping
• 3 cups low sodium chicken broth: Low sodium broth is crucial since the sauce reduces and concentrates salt
• 1 teaspoon Italian seasoning: This blend brings all the classic herbal notes without measuring multiple dried herbs
• 1 teaspoon paprika: Paprika adds subtle depth and a gorgeous red hue to the finished dish
• 1/2 teaspoon crushed red pepper flakes: Even if you do not love heat, this tiny amount wakes up all the other flavors
• Salt and black pepper: Seasoning at each stage builds layers of flavor rather than an overwhelming salty finish
• 1/2 cup freshly grated Parmesan cheese: Freshly grated melts better and has a cleaner, sharper taste than pre shredded
• 2 tablespoons chopped fresh parsley: This bright garnish cuts through the richness and makes the dish look restaurant worthy

Instructions

Sauté the aromatics:

Set your Instant Pot to Sauté mode and add a drizzle of oil. Cook the onion and bell pepper for 2-3 minutes until they start to soften, then add the garlic for just 30 seconds until fragrant.

Brown the chicken:

Add the chicken pieces and cook for 2-3 minutes, stirring occasionally until they start to develop some color on the outside.

Build the flavor base:

Stir in the tomato paste, Italian seasoning, paprika, and red pepper flakes. Season generously with salt and pepper.

Deglaze the pot:

Pour in the chicken broth and use your spoon to scrape up any browned bits from the bottom—these little caramelized pieces add incredible depth.

Add tomatoes and pasta:

Stir in the crushed tomatoes, then arrange the spaghetti evenly over the top, pressing it lightly into the liquid without stirring it in.

Pressure cook:

Secure the lid and set to Manual or Pressure Cook on high for 7 minutes.

Release pressure:

Allow a natural pressure release for 5 minutes, then carefully quick release any remaining pressure.

Finish with cheese:

Gently stir everything together and add the Parmesan, stirring until it melts into a creamy sauce.

Serve it up:

Taste and adjust the seasoning if needed, then garnish generously with fresh parsley.

This recipe became our go-to when my husband started graduate school and suddenly we needed filling meals that did not require hours of attention. There is something so satisfying about hearing that final steam release, knowing a complete, comforting dinner awaits inside the pot. It has turned countless frantic weeknights into peaceful family meals.

Making It Your Own

Once you have the basic technique down, this recipe invites endless customization. I have added mushrooms, spinach, and zucchini at various points, and the Instant Pot handles them beautifully. The key is learning which vegetables can go in at the start versus which need that quick stir in at the end.

Texture Secrets

The way pasta absorbs liquid under pressure creates a completely different mouthfeel than traditional boiling. Each strand becomes infused with the tomato broth rather than being coated separately. That is why this tastes like it simmered all day even though it took minutes.

Perfect Pairings

This spaghetti is hearty enough to stand alone as a complete meal, but a crisp green salad with acidic vinaigrette cuts through the richness beautifully. I have found that garlic bread, while redundant, is never a bad idea.

• Make extra for tomorrow is lunch—this actually tastes better after the flavors meld overnight
• If the sauce looks too thick, stir in a splash of broth before serving
• Keep red pepper flakes on the table so everyone can adjust their own heat level

There is nothing quite like the sound of family conversation starting up around a steaming bowl of this spaghetti. It is comfort food at its most convenient and delicious.

Recipe Questions & Answers

→ Can I use chicken thighs instead of breasts?

Yes, boneless skinless chicken thighs work beautifully and may add extra richness. Cut them into bite-sized pieces just like breasts, though they might need an extra minute or two of cooking time.

→ Do I need to cook the spaghetti before adding it?

No, the spaghetti cooks directly in the pot along with the sauce and chicken. The liquid from the broth and tomatoes is precisely measured to cook the pasta to perfection during pressure cooking.

→ Why shouldn't I stir the spaghetti into the liquid?

Pressing the spaghetti on top rather than stirring prevents it from clumping together and ensures even cooking. The pasta will soften and absorb the cooking liquid naturally during the pressure cycle.

→ Can I make this without an Instant Pot?

You can adapt this for the stovetop by cooking everything in a large Dutch oven. Simmer covered for about 15-20 minutes until the pasta is tender and the chicken is cooked through, adding more liquid if needed.

→ How should I store leftovers?

Store in an airtight container in the refrigerator for up to 4 days. The pasta will continue absorbing the sauce, so you may want to splash in a little broth when reheating to restore the creamy consistency.

→ Is this dish freezer-friendly?

Yes, it freezes well for up to 3 months. Portion into freezer-safe containers and thaw overnight in the refrigerator before reheating. The texture remains excellent after freezing.
