Ingredients

  • 3 tablespoons olive oil divided
  • 1 yellow onion diced
  • 1 red bell pepper diced
  • 1 green bell pepper diced
  • salt and pepper to taste
  • 1 (32 oz) carton chicken broth
  • 1 (16 oz) box spaghetti noodles broken in half
  • 1 (8 oz) tub sour cream room temperature
  • 1 (8 oz) block cream cheese softened to room temperature
  • 1 (8 oz) block sharp cheddar cheese shredded and divided in 1/2
  • 1 (10.5 oz) can cream of mushroom soup
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon paprika
  • 1/2 teaspoon dried basil
  • 1/2 teaspoon Italian seasoning
  • 4 cups cooked and cubed chicken about 1 pound (I used 1 rotisserie chicken with skin removed)
  • 1/4 cup finely grated parmesan cheese

Instructions

  • Preheat oven to 450 degrees F and grease a deep 9x13 inch baking dish with cooking spray. Set aside.
  • Hit SAUTE on your 6 quart Instant Pot.
  • Once it reads HOT, add in 2 tablespoons olive oil, onion, red bell pepper, and green bell pepper.
  • Cook, stirring regularly, until the veggies are tender, about 5-10 minutes.
  • Taste and season with salt and pepper.
  • Remove from the Instant Pot and set aside.
  • Hit CANCEL on the Instant Pot.
  • Pour in broth, scraping up any brown bits from the bottom. This will prevent a BURN reading.
  • Add in uncooked noodles and remaining 1 tablespoon olive oil.
  • Stir to combine. Be sure the noodles are fully submerged.
  • Close and lock the lid - make sure the pressure valve is pointing to SEALING.
 Cook on HIGH pressure for 5 minutes, then flip the valve to quick release the pressure.
  • While the pasta is cooking, place sour cream, cream cheese, 1/2 the shredded cheddar cheese, mushroom soup, onion powder, garlic powder, paprika, basil, and Italian seasoning into a large bowl.
  • Beat, using a hand mixer, until well combined.
  • Stir in the cooked chicken and cooked veggies.
  • When the pasta is done cooking, dump the pasta and the broth (everything in the Instant Pot) into the sauce.
  • Taste and re-season with salt.
  • Pour into prepared dish and sprinkle with remaining cheddar and parmesan.
  • Bake in preheated oven until the cheese has melted and the center is hot, about 15-20 minutes.
  • Serve and enjoy!
