Instant Pot Creamy Chicken Spaghetti

 

1 pound boneless skinless chicken breasts, cut into 1-inch cubes

1 medium red bell pepper, seeded and diced

½ medium yellow onion, diced

1 C. roughly chopped white mushrooms

1 T. extra-virgin olive oil

1½ tsp. garlic powder

1½ tsp. fine sea salt

½ tsp. ground black pepper

16 ounces gluten-free spaghetti

3 C. chicken broth or stock

1 C. sour cream

 

Preheat an electric pressure cooker using the SAUTÉ function. When the display panel reads HOT, add the chicken, bell pepper, onion, mushrooms, olive oil, garlic powder, sea salt, and black pepper. Using a wooden spoon, stir periodically and cook until the chicken browns on all sides and the onion begins to turn translucent, about 5 minutes. Break the spaghetti into thirds and place in the pot. Cover the pasta with the chicken broth, then place the lid on the pressure cooker. Make sure the vent valve is in the SEALING position. Using the display panel, press the CANCEL button. Select the MANUAL/PRESSURE COOK function and HIGH PRESSURE. Use the +/− buttons until the display reads 6. When the cooker beeps to let you know it’s finished, switch the vent valve from the SEALING to the VENTING position, administering a quick release. Use caution while the steam escapes—it’s hot. Stir in the sour cream and let sit for 5 minutes before serving.
