Savory Instant Pot Chicken Spaghetti

The aroma of bubbling tomato sauce and tender chicken wafting from my Instant Pot always takes me back to rainy Tuesday evenings when I needed something comforting but had zero energy for standing over a stove. This dish became my go-to when I discovered that breaking spaghetti in half wasn't sacrilege—it was actually brilliant for pressure cooking. Now it's the meal my family requests when they want something that tastes like it simmered all day but really came together in minutes.

Last winter my sister came over completely exhausted from work and I made this for us both. She took one bite and literally put her fork down to ask how something this creamy and rich could be so simple. Now she texts me every time she makes it saying her house smells like an Italian restaurant.

Ingredients

• Chicken breasts: Cutting them into bite sized pieces before cooking ensures they stay tender and absorb all the seasoning
• Onion and bell pepper: These aromatics build the flavor foundation so dont rush the sauté step
• Garlic: Fresh minced garlic adds that punch of flavor that makes the dish taste homemade
• Crushed tomatoes: Using the whole can creates that perfect sauce consistency that clings to every strand of spaghetti
• Tomato paste: This concentrated tomato magic deepens the sauce and gives it that slow simmered taste
• Spaghetti: Breaking it in half makes it fit perfectly in the pot and easier to serve
• Chicken broth: Low sodium gives you control over the salt level while still adding depth
• Italian seasoning: This blend saves time but feel free to customize with your favorite herbs
• Paprika: Adds a subtle sweetness and beautiful color to the sauce
• Red pepper flakes: Optional but they add just the right amount of warmth
• Parmesan cheese: Freshly grated melts better and tastes way better than the pre shredded stuff
• Fresh parsley: Brightens up the whole dish and makes it look like you put in way more effort

Instructions

Sauté the aromatics:

Set your Instant Pot to Sauté mode and let it get hot then add a splash of oil. Toss in your onion and bell pepper cooking them for 2 to 3 minutes until they start to soften and smell amazing. Add the garlic for just 30 seconds—you want it fragrant not burned.

Brown the chicken:

Add those bite sized chicken pieces to the pot stirring occasionally for 2 to 3 minutes. You're looking for a nice golden color on the outside but don't worry about cooking them through—they'll finish perfectly under pressure.

Add the seasonings:

Stir in the tomato paste Italian seasoning paprika and those red pepper flakes if you like a little heat. Season everything with salt and pepper making sure to coat the chicken and vegetables evenly.

Deglaze and add liquids:

Pour in the chicken broth and use your wooden spoon to scrape up any browned bits stuck to the bottom—that's where the flavor lives. Add the crushed tomatoes and stir to combine everything into a beautiful sauce.

Add the spaghetti:

Spread the broken spaghetti pieces evenly over the top of the sauce. Here's the trick—press them down gently into the liquid but don't stir. The pasta needs to stay on top to cook properly under pressure.

Pressure cook:

Secure that lid and set your Instant Pot to Manual or Pressure Cook on high for exactly 7 minutes. Don't worry—it knows what it's doing. Once the timer beeps let the pressure release naturally for 5 minutes then carefully do a quick release.

Finish and serve:

Gently stir everything together watching as the sauce transforms into something creamy and gorgeous. Stir in the Parmesan until it's melted and then taste it—you might need another pinch of salt or pepper. Serve it up with a generous sprinkling of fresh parsley.

This recipe has saved me so many times when I've had unexpected guests drop by or just completely forgot to plan dinner until 6 PM. Something about dumping everything in one pot and having it come out restaurant quality feels like magic every single time.

Making It Your Own

Once you've got the basic technique down this recipe becomes a canvas for whatever you have in your fridge or whatever your family loves. I've made countless variations and each one feels like a new discovery.

Perfect Pairings

A crisp green salad with a bright vinaigrette cuts through the richness beautifully and adds that fresh element we all need. Some warm garlic bread on the side turns this into the kind of meal that makes everyone linger at the table a little longer.

Storage and Reheating

This dish actually tastes better the next day as all those flavors have more time to meld together. Store leftovers in an airtight container in the fridge for up to four days.

• Add a splash of broth when reheating to bring back the creamy consistency
• The pasta will absorb more liquid overnight so don't panic if it looks thicker
• Freeze individual portions for those nights when cooking is absolutely not happening
