Instant Pot Lasagna Soup: A Quick and Easy Comfort Food Favorite

Instant Pot lasagna soup is the easiest way to enjoy all the classic flavors of lasagna without layering or baking. It’s rich, savory, and packed with tender pasta, perfectly seasoned Italian sausage, and garlicky tomato broth. Plus, each bowl is topped with grated Parmesan for just the right amount of cheesy goodness. Trust me, your house will smell like an Italian trattoria, and everyone will be hovering in the kitchen waiting to dig in.

Growing up, lasagna was always a weekend project in our house, and while I still love diving into the traditional layered version, this easy lasagna soup recipe gives you all the flavor with half the effort. I’ve tested (and tweaked!) this recipe time and time again to make it foolproof, and it’s become my family’s most-requested dinner whenever we’re craving something hearty yet quick. Let’s get that Instant Pot working!

Why This Instant Pot Lasagna Soup Is So Irresistible

• Quick and easy: Ready in under 45 minutes, this dish doesn’t skimp on lasagna-esque flavor, but skips hours of layering.
• Bold flavors: The combination of Italian sausage, garlic, onions, and marinara sauce gives every bite an authentic, rich taste.
• Perfectly cooked pasta: The Instant Pot ensures that the lasagna noodles are tender without turning mushy.
• One-pot convenience: Fewer dishes = more time to relax and enjoy your meal.
• Customizable: Swap proteins, add vegetables, or make it creamy with a dollop of ricotta—there’s room to make it your own.

Essential Ingredients for Perfect Instant Pot Lasagna Soup

While every ingredient plays its part, here are the four stars of the show that truly make this homemade lasagna soup shine:

• Italian sausage: I use mild Italian sausage to add just the right balance of spices and richness. If you prefer extra heat, hot Italian sausage works beautifully too.
• Marinara sauce: A high-quality marinara will make a noticeable difference. Look for one with no added sugar and rich tomato flavor. You can even make your own if you want to go the extra mile!
• Lasagna noodles: Traditional lasagna noodles broken into bite-sized pieces mimic the textures of lasagna best. Avoid substituting with smaller pasta shapes as they may overcook.
• Parmesan cheese: Don’t skimp here! Freshly grated Parmesan adds a salty, nutty finish that ties everything together.

Instant Pot Lasagna Soup Ingredients

• 1 (4 ounce) mild Italian sausage link, casing removed
• 1 pound ground sirloin
• 1 tablespoon olive oil
• 1 cup finely chopped onion
• 1 tablespoon garlic, minced
• 1 (32 ounce) can low-sodium chicken broth
• 24 ounces marinara sauce
• 8 lasagna noodles, broken into pieces
• ½ teaspoon salt
• ½ teaspoon freshly ground black pepper
• 6 teaspoons grated Parmesan cheese

How to Make Instant Pot Lasagna Soup

1. Turn on your Instant Pot and select the Sauté function. Cook the Italian sausage and ground sirloin until browned, about 5 minutes. Drain any excess grease and set the meat aside.
2. Add olive oil to the pot and swirl to coat. Toss in the chopped onion and sauté until softened, but not browned, about 5 minutes. Stir in the garlic and let it cook for just 1 minute until fragrant.
3. Pour in the chicken broth and deglaze the pot, using a wooden spoon to scrape up any flavorful browned bits stuck to the bottom.
4. Add the marinara sauce, browned meat, salt, and pepper. Stir everything together to combine evenly.
5. Break the lasagna noodles into pieces and submerge them fully in the sauce mixture. Lock the lid in place and set the Instant Pot to high pressure for 3 minutes. It will take about 10-15 minutes for the pressure to build up.
6. Once the cooking is complete, carefully use the quick-release method to release the pressure. This takes about 5 minutes. Remove the lid and give everything a good stir. Taste and adjust the seasoning, adding more salt if needed.
7. Ladle the soup into bowls and top each with a teaspoon of freshly grated Parmesan cheese. Serve immediately and enjoy!

Expert Tips for the Best Instant Pot Lasagna Soup

• Use good quality sausage: The sausage is a major flavor-driver in this recipe, so pick a brand you love.
• Don’t skip deglazing: Scraping the bottom of the pot after adding the broth prevents the dreaded “burn” warning and ensures maximum flavor.
• Serve fresh: This soup is at its best right after cooking since the noodles can continue to absorb liquid as it sits.
• Add ricotta for creaminess: If you want a richer, creamier soup, stir in a dollop of ricotta before serving.
• Meal prep idea: If you’re planning to eat leftovers, cook the noodles separately and add them to each portion as you reheat.
• Storage: Store in an airtight container for up to 3 days. Reheat gently on the stove or microwave and add a splash of broth to loosen.

Delicious Instant Pot Lasagna Soup Variations

• Vegetarian option: Swap out the sausage and ground beef for plant-based alternatives or additional veggies like zucchini, spinach, or mushrooms.
• Spicy twist: Use hot Italian sausage and a pinch of red pepper flakes for an extra kick.
• Cheesy indulgence: Stir shredded mozzarella or provolone into the soup just before serving.
• Gluten-free adaptation: Use gluten-free lasagna noodles—you may need to adjust the cooking time slightly.

Instant Pot Lasagna Soup FAQs

Can I use a different type of pasta?

Yes, but sticking with broken lasagna noodles gives it that classic lasagna vibe. If you opt for another shape, reduce the cooking time since smaller pastas cook faster.

Is this recipe freezer-friendly?

This soup doesn’t freeze well due to the noodles absorbing too much liquid. If you want to freeze it, cook the noodles separately and omit them from the portion you’re freezing.

Can I make this recipe creamy?

Absolutely! Stirring in some ricotta, heavy cream, or even mascarpone after cooking will make the soup richer and creamier.

What marinara sauce should I use?

Pick your favorite high-quality store-bought marinara or make your own at home for a little extra effort. Look for one with no added sugar for the best flavor balance.

How do I avoid overcooking the noodles?

Ensure the noodles are fully submerged in the liquid and follow the specified pressure cooking times carefully. Avoid letting the soup sit for too long after cooking.
