Ingredients

• Ground beef or Italian sausage
• Onion
• Garlic
• Crushed tomatoes

• Chicken or beef broth
• Lasagna noodles (broken into pieces)
• Italian seasoning
• Salt and pepper
• Ricotta cheese
• Mozzarella cheese
• Parmesan cheese
• Fresh basil (optional)

Step-by-Step Instructions

1. Start with sauté mode :Turn on the Instant Pot and use sauté mode to cook the ground meat. Break it apart as it cooks so you get small, even pieces. Once browned, remove excess grease if needed.
2. Build the flavor base :Add chopped onion and garlic directly into the pot. Let them cook for a couple of minutes until fragrant. This step matters – don’t rush it, it builds depth.
3. Add tomato components: Stir in crushed tomatoes and tomato paste. Mix well so the paste dissolves completely into the sauce. This creates that thick, rich lasagna flavor.
4. Pour in broth and seasoning :Add broth, Italian seasoning, salt, and pepper. Stir everything together and scrape the bottom well to avoid burn warnings.
5. Add broken noodles: Break lasagna sheets into rough pieces and add them in. Don’t over-stir – just gently press them into the liquid.
6. Pressure cook: Close the lid, set to high pressure, and cook for about 5 minutes. It doesn’t sound like much, but it’s enough for pasta in the Instant Pot.
7. Quick release carefully: Once done, do a quick pressure release. Open the lid slowly to avoid splashing.
8. Finish with cheese: Stir the soup gently. Then add dollops of ricotta, shredded mozzarella, and a sprinkle of Parmesan. Let it melt naturally into the soup.
9. Adjust consistency: If it’s too thick, add a splash of broth. If too thin, let it sit – it thickens as it cools.
