  3. 3 Release pressure carefully using the quick-release method according to manufacturer's instructions, about 5 minutes. Unlock and remove the lid. Remove chicken and cut into bite-sized pieces. Add chicken back into the pot. Scatter noodles on top so they don't clump up.

  6. 6 Set an oven rack about 6 inches from the heat source and preheat the oven's broiler. Spray an 8x12-inch casserole dish with cooking spray.
  7. 7 Transfer 1/2 of the spaghetti mixture to the casserole dish and sprinkle with 1/2 cup cheese. Add remaining spaghetti mixture and sprinkle with remaining 1 1/2 cups cheese.
