Prep time: 10 mins | Cook time: 8 mins (plus time to reach pressure) | Servings: 6
Ingredients
- The Protein: 1 lb ground beef or Italian sausage.
- The Pasta: 16 oz spaghetti noodles, broken in half.
- The Sauce & Liquid:
- 1 jar (24 oz) marinara sauce.
- 3 cups water or beef broth (just enough to cover the noodles).
- 1/2 small onion, finely diced.
- The Seasoning: 1 tsp Italian seasoning, 1/2 tsp garlic powder, and salt/pepper to taste.
- The Topping: 1.5 cups shredded mozzarella or parmesan cheese.
Instructions
- Sauté: Set the Instant Pot to Sauté mode. Brown the ground beef and diced onions until the meat is no longer pink. Drain any excess grease.
- Deglaze: Pour in 1/2 cup of the water or broth. Use a wooden spoon to scrape all the browned bits (fond) off the bottom of the pot to prevent a “burn” notice.
- Layer: * Lay the broken spaghetti noodles over the meat in a “criss-cross” pattern to prevent them from clumping together.
- Pour the jar of marinara sauce over the noodles.
- Pour the remaining water/broth over the sauce. Do not stir. Use a spoon to gently press the noodles down so they are mostly submerged in liquid.
- Pressure Cook: Close the lid and set the valve to Sealing. Cook on Manual/High Pressure for 8 minutes.
- Release: When the timer goes off, perform a Quick Release of the pressure.
- Finish: Open the lid and stir the spaghetti well to incorporate the sauce. The sauce may look thin at first but will thicken as it sits.
- Cheesy Topping: Sprinkle the mozzarella cheese over the top and close the lid for 2–3 minutes to let it melt into a bubbly, golden layer.
