Ingredients You’ll Need
Making Instant Pot Chicken Spaghetti requires simple ingredients that many kitchens already have. Each ingredient plays a role in building flavor, texture, and creaminess.
Pasta and Liquid Base
Dry spaghetti forms the base of this dish. Breaking the pasta in half helps it fit neatly inside the Instant Pot. Meanwhile, arranging it in a crisscross pattern prevents the strands from sticking together.
Chicken stock or broth cooks the pasta while adding deep flavor. As the spaghetti cooks, it absorbs the broth and becomes tender. Regular spaghetti works best for the cooking time listed in this recipe.
Chicken and Seasonings
Boneless skinless chicken breast provides lean protein and cooks quickly under pressure. Cutting the chicken into small one inch cubes helps it cook evenly with the pasta.
Salt and black pepper bring balance to the dish. Meanwhile, the chicken releases juices while cooking, which blends nicely with the broth and tomatoes.
Vegetables and Flavor Boosters
Chopped onion and bell pepper add sweetness and texture. Meanwhile, minced garlic brings a warm savory flavor that pairs well with chicken.
Diced tomatoes with green chiles give the sauce a gentle kick. They also add acidity, which balances the creamy cheese later in the recipe.
Creamy and Cheesy Finish
Cream cheese creates a smooth and rich base for the sauce. Once stirred in, it melts into the pasta and broth.
Shredded Monterey Jack or Colby Jack cheese adds the final creamy texture. As it melts, the sauce becomes thick, cheesy, and comforting.
How to Make Instant Pot Chicken Spaghetti (Step by Step)
Layer the Spaghetti Correctly
First break the dry spaghetti in half so it fits easily inside the Instant Pot. Next arrange the pasta in a crisscross pattern across the bottom of the pot.
This simple step prevents the noodles from clumping together during cooking. Also, it allows the broth to flow between the pasta strands.
Meanwhile, keeping the pasta evenly spread helps it cook at the same rate.
Add Broth, Chicken, and Seasonings
Next pour the chicken broth over the spaghetti. Then add the cubed chicken, salt, pepper, chopped onion, bell pepper, garlic, and diced tomatoes with green chiles.
Gently press everything down so the pasta remains covered by liquid. However, do not stir the mixture before pressure cooking.
Pressure Cook
Secure the Instant Pot lid and set it to high pressure for 6 minutes.
After the cooking cycle finishes, allow the pressure to release naturally for 5 minutes. Then carefully release the remaining pressure manually.
Stir in the Cheeses
Open the lid and stir the pasta mixture gently. The spaghetti should be tender and coated in flavorful broth.
Next add the cream cheese and shredded cheese. Stir slowly until the cheeses begin to melt and combine with the sauce.
Rest and Thicken
Close the lid again with the heat turned off. Let the pasta rest for about 10 minutes.
During this time the cheese melts fully and the pasta absorbs extra liquid. As a result, the sauce becomes thick and creamy. Stir once more before serving.
Pro Tips for Perfect Instant Pot Chicken Spaghetti
Preventing the Burn Notice
Always keep the pasta submerged in liquid before pressure cooking. This helps prevent the burn notice on the Instant Pot.
Also avoid stirring the ingredients before cooking. Instead gently press them down so the pasta stays below the broth.
Adjusting Cook Time for Different Pasta
Regular spaghetti works best for this recipe because the cook time matches perfectly.
However, if you use thin spaghetti or short pasta like rotini or ziti, reduce the pressure cook time slightly. Otherwise the pasta may become too soft.
Using Pre Cooked Chicken
If you already have cooked chicken, you can still make Instant Pot Chicken Spaghetti easily.
Simply cook the pasta and vegetables as directed. Then stir the cooked chicken into the pasta when you add the cheeses.
Variations and Substitutions
Add More Vegetables
You can easily add extra vegetables to this recipe. Broccoli, mushrooms, or spinach work well.
Meanwhile, these vegetables cook quickly and blend nicely with the creamy sauce.
Change the Flavor Profile
For a different flavor style, try diced tomatoes with basil and garlic instead of green chiles.
You can also add Italian seasoning to give the pasta a classic Italian inspired flavor.
Make It Your Own
If you prefer a milder dish, you can skip the bell peppers or onions.
You can also swap the cheese varieties. For example mozzarella or cheddar will still create a creamy sauce.
Storage and Reheating
Store leftover Instant Pot Chicken Spaghetti in an airtight container in the refrigerator for up to 4 days.
When reheating, add a small splash of water or chicken broth. Then warm the pasta slowly in the microwave or on the stovetop.
Meanwhile, stirring occasionally helps restore the creamy texture. As a result, the sauce becomes smooth again instead of thick or dry.
