How to make this Instant Pot cheesy, creamy chicken spaghetti

If you’re ready to get cooking this Instant Pot chicken spaghetti, feel free to scroll to the recipe card at the end of this post. However, if you prefer to see some step-by-step photos along with some tips for making this Instant Pot chicken pasta, read on!

This one-pot Instant Pot Cheesy Chicken Spaghetti recipe starts by selecting the Sauté function on a multi-function electric pressure cooker (such as an Instant Pot). Melt the butter in the pot. While the butter is melting, season bite-size chunks of chicken with seasoning salt. Once the butter has melted, add the chicken and some minced garlic to the pot and sauté until the chicken is just starting to brown (about 4 minutes). You don’t need to worry about the chicken being completely cooked through, as it will cook more later while pressure cooking.

How to make Instant Pot Cheesy Chicken Spaghetti

Push Cancel to end Sauté function, and remove the chicken with a slotted spoon and set aside.

Add chicken stock to the pot and stir with a wooden or plastic spoon, scraping the bottom of the pot to loosen any browned bits. Deglazing the pot like this after sautéing is an important step for pressure cooker pasta and rice recipes to help you avoid the dreaded Burn warning.

Without stirring, add the spaghetti noodles (broken in half), salt, pepper, garlic powder, onion powder, and cumin to the pot, then make sure the noodles are all submerged in the liquid before taking the next step in this chicken spaghetti Instant Pot recipe.

Pour the canned diced tomatoes over the top of the pasta, but do not stir it – just layer it on top. Next, place the cream cheese cubes over the top of the tomatoes, along with the reserved chicken, also without stirring.

Close and lock the pressure cooker lid, make sure the pressure/steam release switch is set to sealing, and set the cooking time to 8 minutes at high/normal pressure (also sometimes referred to as “manual”). It will take about 16 minutes for the pot to reach pressure before that 8 minutes of cooking time begins. After the pressure cooking time ends, carefully release the pressure from the pot using the manufacturer’s quick release method.

After all the pressure has released, carefully unlock and open the lid. You’ll see that the Instant Pot chicken spaghetti still looks pretty liquidy, but don’t worry! That’s how it is supposed to look at this point.

Add the shredded Cheddar cheese to the pot, stirring until the cream cheese and Cheddar cheese have completely blended into the pasta sauce and any noodles that were stuck together have broken up. You’ll start to see the Instant Pot Cheesy Chicken Spaghetti sauce thickening up a lot more at this point, but it will continue to thicken over the next few minutes.

Before serving, let the pasta sit in the pot for about 3 more minutes. It will thicken up quite a bit as it sits for those 3 minutes! Once the thickness is to your liking, go ahead and serve up your Instant Pot chicken spaghetti!

You can garnish your pasta with some fresh parsley if desired. It’s not required, but it does make the Instant Pot cheesy chicken pasta look a little prettier if you want to share your #dinnergram on social media.

See? Pretttyyyy! But again, parsley is totally just for looks in this recipe.
