Instant Pot Creamy Pasta with Chicken Thighs and Mushrooms

Step 1
Select the Saut? function on a multi-functional electric pressure cooker (such as an Instant Pot). Melt the butter in the pot. Add the chicken, mushrooms, minced garlic, rosemary, and thyme to the pot and saut? until the chicken is just starting to brown and the mushrooms are starting to soften, about 5 minutes. Push Cancel to end Saut? function, and remove the chicken and mushrooms with a slotted spoon and set aside.

Step 2
Add the chicken stock, salt, pepper, garlic powder, and onion powder to the pot and stir with a wooden or plastic spoon, scraping the bottom of the pot to loosen any browned bits. Add linguine to the pot, making sure the noodles are all submerged in the liquid, but do not stir.

Step 3
Return the chicken and mushrooms to the pot, placing on top of the noodles without stirring. Place the cream cheese cubes over the top of the chicken, and do not stir. Close and lock the lid, making sure the pressure/steam release switch is set to Sealing.

Step 4
Select high pressure according to manufacturer's instructions; set timer for 6 minutes for al dente noodles, adding 1 minute if you want softer noodles. Allow 10 to 15 minutes for pressure to build.

Step 5
Release pressure carefully using the quick-release method according to manufacturer's instructions, about 5 minutes. Unlock and remove the lid.

Step 6
Add Parmesan cheese, heavy cream, and parsley to the pot, stirring until the cream cheese and Parmesan cheese have completely blended into the pasta sauce and any noodles that were stuck together have broken up. Let the pasta sit in the pot, stirring occasionally, until the sauce is thickened, 3 to 5 minutes, before serving.
