Savory Instant Pot Chicken Spaghetti (Printable)

Tender chicken and spaghetti in a rich tomato sauce made quickly in the Instant Pot for an easy weeknight dinner.

# What You Need:

→ Meats

01 - 2 large boneless, skinless chicken breasts (about 1.1 lbs), cut into bite-sized pieces

→ Vegetables & Aromatics

02 - 1 medium onion, finely chopped
03 - 3 cloves garlic, minced
04 - 1 red bell pepper, diced
05 - 1 can (14 oz) crushed tomatoes
06 - 2 tablespoons tomato paste

→ Pasta

07 - 8 oz uncooked spaghetti, broken in half

→ Liquids

08 - 3 cups low-sodium chicken broth

→ Seasonings

09 - 1 teaspoon Italian seasoning
10 - 1 teaspoon paprika
11 - 1/2 teaspoon crushed red pepper flakes (optional)
12 - Salt and black pepper to taste

→ Cheeses & Finishing

13 - 1/2 cup freshly grated Parmesan cheese
14 - 2 tablespoons chopped fresh parsley (for garnish)

# How To Make It:

01 - Set the Instant Pot to 'Sauté' mode. Add a drizzle of oil, then sauté the onion and bell pepper for 2-3 minutes until softened. Add garlic and cook for 30 seconds until fragrant.
02 - Add chicken pieces and cook for 2-3 minutes, stirring occasionally, until starting to brown (they do not need to be fully cooked through).
03 - Stir in tomato paste, Italian seasoning, paprika, and crushed red pepper flakes (if using). Season with salt and pepper.
04 - Pour in chicken broth and deglaze the pot, scraping any browned bits from the bottom.
05 - Add crushed tomatoes and spread spaghetti evenly over the top, pressing down lightly into the liquid (do not stir).
06 - Secure the lid. Set Instant Pot to 'Manual' or 'Pressure Cook' on high for 7 minutes.
07 - Once cooking is complete, allow a natural pressure release for 5 minutes, then carefully do a quick release.
08 - Gently stir everything together. Add Parmesan cheese and stir until melted and creamy. Taste and adjust seasoning if needed. Serve garnished with parsley.

# Expert Suggestions:

01 -
  • Everything cooks in one pot, meaning less cleanup and more time for what actually matters
  • The spaghetti absorbs all those flavorful juices while pressure cooking, creating a sauce that tastes like it simmered all afternoon
  • Its forgiving enough for busy weeknights but impressive enough for company
02 -
  • Don't be tempted to stir the spaghetti into the liquid before pressure cooking—laying it on top prevents sticking and ensures even cooking
  • The sauce will look thinner than you expect immediately after cooking but thickens nicely as it stands and as you stir in the cheese
  • If you hear the dreaded burn notice, don't panic—quick release and check that nothing is stuck to the bottom, then continue cooking
03 -
  • Use a wooden spoon or silicone spatula to scrape the bottom of the pot when deglazing—metal can damage the cooking surface
  • If your spaghetti seems too al dente after pressure cooking, simply let it sit for a few more minutes with the lid off—the residual heat finishes the job without overcooking anything
