Key Ingredients for Instant Pot Lasagna Soup

See recipe card below for full list of measurements, ingredients, and instructions.

Italian Sausage or Ground Beef

Using Italian sausage (mild or spicy) or ground beef gives this soup its rich, deeply savory base. Sausage brings bold, herby flavors, while beef keeps it classic. You can use turkey or chicken sausage for a lighter touch. If you’re after a vegetarian option, swap in lentils or plant-based crumbles—just note that the flavor profile will be milder.

Lasagna Noodles

Lasagna noodles are the star! Break them into bite-size pieces so every scoop feels like the edge of a lasagna slice. Regular or oven-ready noodles both work—just keep an eye on the cook time. In a pinch, any short pasta like fusilli or broken spaghetti can step in, though classic lasagna noodles give the most authentic vibe.

Crushed Tomatoes

Crushed tomatoes create that signature, robust sauce. Go with high-quality canned for deep tomato flavor. For a chunkier result, you can use diced tomatoes instead. If you love extra depth, add a spoon of tomato paste. Roasted tomato varieties add a subtle sweetness.

Ricotta, Mozzarella, and Parmesan

This creamy, cheesy trio is what makes the “soup” feel truly lasagna-like. Ricotta adds richness, mozzarella gives you those gorgeous cheese pulls, and parmesan delivers a nutty, salty pop. If you want it lighter, just use one or two cheeses—or vegan cheese for a dairy-free twist.

Italian Seasoning Blend

A good Italian seasoning blend brings together basil, oregano, thyme, and rosemary—key to that classic Italian aroma. Mix your own from dried herbs, or use store-bought. Want extra kick? Add a pinch of crushed red pepper flakes!

Instructions for Instant Pot Lasagna Soup

See recipe card below for full list of measurements, ingredients, and instructions.

Sauté the Meat and Aromatics

Turn your Instant Pot to the sauté setting. Add olive oil, then cook the Italian sausage (or ground beef) until browned, breaking it up as you go. Toss in diced onion and cook until it’s soft and translucent, about 3 minutes. Stir in the garlic, salt, pepper, Italian seasoning, and red pepper flakes for another 30 seconds, until fragrant.

Build the Broth

Add the tomato paste to the pot and stir it into the meat mixture for about a minute, letting it deepen in color. Pour in the chicken broth and scrape up any bits from the bottom (this prevents the burn notice!). Add the crushed tomatoes and sugar if using, giving everything a good stir.

Add Noodles and Pressure Cook

Break up the lasagna noodles and add them to the pot—make sure they’re submerged in the liquid. Lock the Instant Pot lid, set the valve to sealing, and cook on Manual/High Pressure for 6 minutes.

Quick Release and Stir in Cheese

Once the timer beeps, carefully quick-release the pressure. Stir in the ricotta, mozzarella, parmesan, and fresh basil until melted and creamy. If using baby spinach, add now and stir until wilted. Taste and adjust seasoning if needed.

Serve and Enjoy

Ladle the hot soup into bowls. Top with extra mozzarella or parmesan and fresh basil if you like. Serve immediately and savor all those classic lasagna flavors—in soup form!

Recipe Variations

Vegetarian Twist

Skip the meat and bulk up your soup with lentils or canned white beans instead. They add satisfying protein and hearty texture, turning this into a wonderful meatless main course!

Dairy-Free or Vegan Option

Use plant-based ground “meat” and swap the cheeses for your favorite dairy-free ricotta and mozzarella-style shreds. A splash of cashew cream makes it extra luscious.

Make It Gluten-Free

Choose your favorite gluten-free lasagna noodles (or another short gluten-free pasta) and follow the recipe as usual. Just monitor the cook time, as some GF pastas cook faster.

Kick Up the Heat

Add more crushed red pepper flakes, or use hot Italian sausage to bring bold, spicy flavor to your soup. You can also finish with a sprinkle of chili oil.

More Veggies

Stir in diced zucchini, chopped bell peppers, or mushrooms along with the onions to pack even more nutrition and flavor into your bowl.

Serving Suggestions

For a complete Italian-inspired feast, serve this Instant Pot Lasagna Soup with a crisp Caesar salad and plenty of crusty garlic bread for dunking. Finish with fresh basil, extra parmesan, or a dollop of ricotta on top. A side of roasted broccoli or a simple antipasto platter also pairs beautifully.

Storage and Reheating

Store leftover soup in an airtight container in the refrigerator for up to 4 days. The noodles will absorb some broth as it sits, so stir in extra chicken broth or water when reheating to loosen. Warm gently on the stovetop or in the microwave until steaming hot. Freeze cooled soup (without dairy/cheese mixed in) for up to 2 months—just thaw overnight, reheat, and add cheeses just before serving for the best texture.

Frequently Asked Questions About Instant Pot Lasagna Soup (FAQ)

Q: Can I make this ahead of time?
A: Absolutely! It's great for meal prep and tastes even better the next day. Just store in the fridge and reheat with a splash of extra broth.

Q: Can I cook this on the stovetop instead of the Instant Pot?
A: Yes! Sauté meat and veggies in a Dutch oven, add liquids and noodles, then simmer covered until pasta is tender (about 15-20 minutes). Stir in cheese and serve.

Q: How can I prevent the burn notice on my Instant Pot?
A: After sautéing, always scrape up all browned bits from the bottom when adding broth. Avoid stirring the noodles too much after adding to the pot so they don’t stick.

Q: Can I use different types of cheese?
A: Definitely! Try cottage cheese for ricotta, provolone for mozzarella, or even a little fontina for extra richness.
