Savory Instant Pot Chicken Spaghetti

The first time my friend Sarah brought this chicken spaghetti to our Tuesday night potluck, I honestly thought she'd spent hours simmering sauce on the stove. She laughed when I asked for her grandmother's recipe and pulled out her Instant Pot instead. Now it's my go-to when I want something that tastes like it cooked all day but actually took minutes.

Last winter when my sister was recovering from surgery, I made this for her family three nights in a row because she kept requesting it. Her kids usually complain about 'bits' in their pasta, but they demolished this every single time. There's something about how the chicken gets so tender and the spaghetti so perfectly coated that makes everyone feel taken care of.

Ingredients

• Chicken breasts: Cutting them into bite-sized pieces before cooking helps them absorb more flavor and cook evenly
• Onion and bell pepper: These create the aromatic foundation that makes your kitchen smell amazing
• Garlic: Fresh minced garlic gives you that authentic Italian restaurant quality
• Crushed tomatoes: The base of our sauce, providing rich tomato flavor without needing to simmer for hours
• Tomato paste: Concentrates the tomato flavor and adds natural thickness to the sauce
• Spaghetti: Breaking it in half helps it fit better in the pot and makes it easier to serve
• Chicken broth: Low-sodium lets you control the salt level while still cooking the pasta perfectly
• Italian seasoning: A convenient blend that provides classic herb flavors without measuring multiple spices
• Paprika: Adds subtle depth and a beautiful red color to the dish
• Crushed red pepper flakes: Optional, but gives a gentle warmth that balances the rich sauce
• Parmesan cheese: Freshly grated melts better and provides that nutty, salty finish
• Fresh parsley: Brightens up the dish and adds a pop of color that makes it look restaurant worthy

Instructions

Sauté the aromatics:

Set your Instant Pot to Sauté mode with a drizzle of oil, then cook the onion and bell pepper until they're softened and fragrant, about 2-3 minutes. Add the garlic for just 30 seconds so it doesn't burn.

Brown the chicken:

Add the chicken pieces and cook for 2-3 minutes, stirring occasionally until they're lightly golden on the outside. Don't worry about cooking them through, the pressure cooking will finish the job perfectly.

Add the seasonings:

Stir in the tomato paste, Italian seasoning, paprika, and red pepper flakes if using. Season with salt and pepper, letting the tomato paste caramelize slightly with the aromatics.

Deglaze the pot:

Pour in the chicken broth and use your spoon to scrape up any browned bits from the bottom of the pot. This step adds incredible depth of flavor to the final dish.

Layer in tomatoes and pasta:

Add the crushed tomatoes, then arrange the spaghetti pieces evenly over the top, pressing them gently into the liquid. Resist the urge to stir, this prevents the pasta from sticking together.

Pressure cook:

Secure the lid and set to Manual or Pressure Cook on high for exactly 7 minutes. The pasta will come out perfectly al dente every time.

Release pressure naturally:

Let the pressure release naturally for 5 minutes, then carefully do a quick release. This gradual release helps prevent foaming and keeps the sauce smooth.

Combine and finish:

Gently stir everything together until the pasta is coated in sauce, then stir in the Parmesan until melted and creamy. Taste and adjust the seasoning if needed.

Serve it up:

Portion into warm bowls and sprinkle with fresh parsley for that final touch that makes it feel special.

This became my daughter's requested birthday dinner two years ago when she was going through her 'only pasta' phase. Now she asks for it even when she's willing to eat other things, which I think says more than any restaurant review could.

Getting The Sauce Just Right

The sauce will look slightly thin when you first open the pot, but don't panic. As you stir in the Parmesan and let it sit for a minute, it thickens beautifully. I learned this the hard way when I tried to reduce it longer once and ended up with pasta that was too soft.

Make It Your Own

Chicken thighs work beautifully if you prefer dark meat, just trim excess fat before cooking. Sometimes I throw in mushrooms or spinach during the sauté stage when I want to sneak in more vegetables. My neighbor adds a splash of heavy cream at the end and swears it's restaurant quality.

Perfect Pairings & Serving Ideas

A crisp green salad with vinaigrette cuts through the richness nicely, and warm garlic bread is non-negotiable in our house. If you're feeding a crowd, double the recipe but use a larger Instant Pot.

• Let the dish rest for 5 minutes before serving to let flavors meld
• Extra Parmesan at the table lets everyone customize their portion
• This reheats beautifully for lunch the next day

There's something so satisfying about serving a dish that tastes like it simmered all day when you know it took less than 40 minutes. That's the magic of the Instant Pot right there.

Recipe FAQs

→ Can I use chicken thighs instead of breasts?

Yes, boneless chicken thighs work beautifully and add extra richness. They may need an extra minute or two of cooking time.

→ Do I need to cook the spaghetti first?

No, the uncooked spaghetti goes directly into the Instant Pot and pressure cooks perfectly in the sauce, absorbing all the flavors.

→ Can I make this spicy?

Absolutely! Increase the crushed red pepper flakes to 1 teaspoon or add some diced jalapeños when sautéing the vegetables.

→ Can I add more vegetables?

Yes, mushrooms, spinach, or zucchini make excellent additions. Add them during the sauté step or stir in spinach after cooking.

→ How should I store leftovers?

Store in an airtight container in the refrigerator for up to 4 days. The pasta will absorb more sauce as it sits.

→ Can I freeze this dish?

Yes, freeze in portion-sized containers for up to 3 months. Thaw overnight in the refrigerator before reheating.
