Ingredients
- 1 tbsp olive oil
- 1 medium yellow onion diced
- 1 lb ground beef
- 2 tsp garlic powder
- 1 tbsp Italian seasoning
- 1 tbsp minced garlic
- 1 tsp salt
- 1/2 tsp black pepper
- 1 jar spaghetti sauce 24 oz
- 1 can diced tomatoes optional
- 16 oz spaghetti noodles broken in half
- 6 cups water divided
Instructions
- Turn Instant Pot to Sauté. Add olive oil and onion; cook 2–3 minutes until softened.
- Add ground beef and cook 5–7 minutes, breaking it up as it browns. Stir in garlic powder, Italian seasoning, minced garlic, salt, and pepper. Sauté 1 more minute.
- Remove beef mixture to a bowl. Pour 3 cups water into the pot and deglaze, scraping the bottom well.
- Layer spaghetti noodles crisscrossed in the pot. Pour in sauce and optional diced tomatoes. Return beef mixture. Pour remaining 3 cups water around edges — do not stir.
- Seal the lid and set valve to Sealing. Cook on High Pressure for 5 minutes. Let naturally release for 5 minutes, then quick release.
- Stir well — sauce will thicken as it rests. Serve hot with Parmesan or basil if desired.
Notes
For a spicy version, add red pepper flakes before pressure cooking. For a creamy twist, stir in a splash of cream after cooking.
