Savory Instant Pot Chicken Spaghetti

Rainy Tuesday nights demand dinner that practically makes itself. I stumbled onto this Instant Pot chicken spaghetti during one of those chaotic weeks when takeout felt like the only option but the budget said otherwise. Now it is become my go-to when I need something that tastes like it simmered all day but actually took minutes.

Last winter my sister was recovering from surgery and I dropped off a container of this. She texted me before she even finished her first bowl asking for the recipe. There is something about that combination of tender chicken and perfectly coated noodles that feels like a hug in a bowl.

Ingredients

• Chicken breasts: Cutting them into bite sized pieces helps them cook evenly and means every forkful has the perfect ratio of meat to pasta
• Onion and red bell pepper: These aromatics build the flavor foundation so do not skip the sauté step even when you are rushing
• Garlic: Fresh minced garlic makes a noticeable difference over the jarred stuff here
• Crushed tomatoes: The backbone of our sauce providing body and that authentic Italian taste
• Tomato paste: Concentrates the tomato flavor and adds a nice richness to the broth
• Spaghetti: Breaking it in half makes it easier to stir later and fits better in the pot
• Chicken broth: Low sodium is crucial since the pasta absorbs and concentrates the salt
• Italian seasoning: Your shortcut to herbs without measuring out separate dried oregano basil and thyme
• Paprika: Adds a subtle warmth and beautiful color to the sauce
• Red pepper flakes: Optional but I love that gentle background heat that builds slowly
• Parmesan cheese: Freshly grated melts better than the pre shredded stuff which has anti caking agents
• Fresh parsley: Brightens up the whole dish and makes it look like you tried harder than you actually did

Instructions

Build your flavor base:

Set that Instant Pot to Sauté mode with a drizzle of oil. Toss in your onion and bell pepper letting them soften for about 3 minutes until they smell amazing. Add garlic for just 30 seconds because burned garlic turns bitter and ruins everything.

Sear the chicken:

Add your chicken pieces and let them cook for 2 to 3 minutes until they start turning golden. They do not need to cook through since the pressure will handle that but getting some color on them adds depth.

Add the seasonings:

Stir in the tomato paste Italian seasoning paprika and those red pepper flakes if you like a little kick. Season everything with salt and pepper now while the flavors are concentrated.

Deglaze the pot:

Pour in the chicken broth and use your spoon to scrape up any browned bits from the bottom. Those bits are pure flavor and deglazing prevents the dreaded burn notice later.

Add tomatoes and pasta:

Pour in the crushed tomatoes then arrange the spaghetti on top pressing it down into the liquid. Do not stir it yet the pasta needs to be submerged to cook properly.

Pressure cook:

Secure the lid and cook on high pressure for 7 minutes. This timing gives you perfectly al dente pasta that is not mushy.

Natural release then quick release:

Let the pressure drop naturally for 5 minutes then carefully switch to quick release. Wait until that float valve drops before opening.

Finish it off:

Gently stir everything together watching how the sauce thickens as you mix. Stir in the Parmesan until it melts into a creamy sauce then taste and adjust seasonings.

Serve it up:

Plate it in bowls and sprinkle fresh parsley on top. Let everyone add extra cheese at the table if they want.

Save

My teenage son who usually survives on cereal and protein bars actually asked for seconds the first time I made this. Watching him go back for a third helping while chatting about his day made this recipe a permanent fixture in our weeknight rotation.

Making It Your Own

Chicken thighs work beautifully here and stay even more tender during pressure cooking. I have also added diced mushrooms or fresh spinach in the last minute of cooking when I need to sneak in extra vegetables for picky eaters.

Perfect Pairings

A crisp green salad with tangy vinaigrette cuts through the richness. Garlic bread is non negotiable in our house because that sauce is too good to leave behind in the bowl.

Storage And Meal Prep

This recipe actually tastes better the next day when the flavors have had time to mingle. Store it in airtight containers for up to four days and reheat with a splash of broth to bring back the creamy texture.

• Freeze portions in individual containers for those nights when cooking feels impossible
• The pasta may absorb more liquid as it sits so plan to add broth when reheating
• Always cool completely before freezing to prevent ice crystals from forming

Some recipes are just dinner but this one has become the meal my family requests when they have had a rough day and need something reliable. That is the highest compliment a weeknight dinner can get.

Recipe FAQs

→ Can I use chicken thighs instead of breasts?

Yes, boneless skinless chicken thighs work wonderfully and add extra richness. Just cut them into bite-sized pieces and follow the same cooking time.

→ Why shouldn't I stir the spaghetti before pressure cooking?

Keeping the spaghetti on top prevents it from sticking to the bottom and potentially burning. The pasta will cook evenly as it sits in the liquid and the natural pressure release helps absorb flavors.

→ Is this dish freezer-friendly?

Absolutely. Cool completely, then store in airtight containers for up to 3 months. Thaw overnight in the refrigerator and reheat gently with a splash of broth if needed.

→ Can I make this gluten-free?

Yes, simply use gluten-free spaghetti and ensure your chicken broth is certified gluten-free. The cooking time may need slight adjustment depending on the pasta brand.

→ How spicy is this dish?

The red pepper flakes are optional, so you control the heat level. Even with them, it provides just a gentle warmth. Omit entirely for a family-friendly version or increase to taste.

→ Why does my spaghetti look too saucy at first?

This is normal. As the dish rests for a few minutes after stirring, the pasta continues to absorb the sauce and it thickens beautifully. If still too saucy, simply let it sit for 2-3 minutes longer.
