The Only Instant Pot Lasagna Soup Recipe You Need

Instant Pot Lasagna Soup began as a frantic weeknight experiment when I craved baked lasagna but lacked the 90 minutes required for layering and baking. I threw everything into my pressure cooker, hoping the flavors would at least mingle.

Traditional lasagna takes too long, and traditional soup recipes often leave you with a gummy, mushy noodle mess that falls apart into unrecognizable starch. This pressure cooker method fixes that. Everything cooks in one pot in under twenty minutes, and the pasta stays perfectly al dente.

By the end, you’ll know how to use the saute function to build deep flavor, the exact pressure release method to stop overcooking, and how to use cottage cheese for a silky, rich finish without any grainy texture.

Why You Will Love This Pressure Cooker Lasagna Soup

There is something deeply comforting about a bowl of soup that tastes exactly like a classic Italian dinner. When you make this easy Instant Pot lasagna soup, you get all the rich, meaty, tomato-heavy goodness of a traditional baked dish without the hassle of boiling noodles separately or carefully spreading ricotta in delicate layers. The pressure cooker traps steam and forces the seasoned broth into the broken pasta. You get a depth of flavor that usually requires hours of simmering on the stovetop.

You will immediately notice the aroma filling your kitchen. It smells like roasted garlic, sweet Italian sausage, and simmering tomatoes. The texture is what truly sets this apart from other soups. The broken lasagna noodles retain a firm, chewy bite that holds up beautifully against the thick, hearty broth. You do not end up with the collapsed, disintegrating pasta strands that often ruin standard stovetop versions.

If you enjoy a good chicken pot pie soup, you already know how satisfying a deconstructed classic can be. This recipe takes that same comforting concept and applies it to Italian cuisine. The meat mixture is incredibly versatile. You can use a combination of ground beef and sweet Italian sausage, or swap in hot sausage if you prefer a spicy kick. The broth thickens naturally as the noodles release their starches during the quick cooking process. You end up with a consistency that clings to the pasta like a rich ragu rather than a watery soup.

You also get a wonderful contrast of temperatures and textures when you serve it. The hot, savory soup base meets the cool, creamy dollop of cheese mixture on top. It is the kind of meal that feels like you spent hours hovering over the stove, but the pressure cooker does the heavy lifting for you. It is perfect for cold winter nights, but honestly, it is so quick and satisfying that I find myself making it year-round whenever the craving for Italian comfort food strikes.

Essential Ingredients for Easy Instant Pot Lasagna Soup

This deconstructed lasagna soup uses a simple, approachable ingredient list. You probably have most of these staples in your pantry and refrigerator right now. To start, you need a solid base of meats. I highly recommend using a blend of one pound of ground beef and half a pound of mild or sweet Italian sausage. The sausage provides a natural fennel and garlic flavor that infuses the entire pot.

For the liquids, you will need one jar of your favorite marinara sauce and one can of diced tomatoes. The marinara provides a seasoned, slow-simmered taste instantly. You will also need four cups of chicken broth to give the soup its liquid volume and add a savory depth.

The Pasta and Cheese Selection

The star of the show is the pasta. You will need eight ounces of dry lasagna noodles. Do not use fresh pasta here, as it will turn to mush under pressure. Break the dry noodles into rough, bite-sized pieces. This makes the soup easy to eat with a spoon and mimics the layered texture of the classic dish.

For the creamy topping, you have options. Traditionalists will want to use ricotta cheese, and it works perfectly. However, I strongly urge you to try cottage cheese. When you blend cottage cheese with a handful of grated parmesan and a pinch of salt, it creates a silky, smooth mixture that melts seamlessly into the hot broth. If you want to explore this technique further, our cottage cheese sweet potato bowl shows another great way to use this underrated ingredient. Finally, you will need shredded mozzarella cheese to stir in at the very end. That gives the soup its classic, gooey cheese pull.

How to Make Instant Pot Lasagna Soup Step by Step

Making lasagna soup in the Instant Pot is a straightforward process, but the order of operations matters. Start by turning your pressure cooker to the saute function. Add a drizzle of olive oil, then toss in your ground beef and Italian sausage. Break the meat apart with a wooden spoon and cook it until it is thoroughly browned and no pink remains. You want to hear that satisfying sizzle and smell the rich fat rendering from the sausage.

Once the meat is browned, add a diced yellow onion and three minced garlic cloves. Let them cook for about two minutes until the onions soften and turn translucent. This step builds your aromatic base.

Deglazing and Pressure Cooking

Now you must deglaze the pot. Pour in half a cup of the chicken broth and use a wooden spoon to scrape up any browned bits stuck to the bottom. Those browned bits pack massive flavor, and scraping them prevents the burn warning from triggering. Once the bottom is clean, add the rest of the chicken broth, the marinara sauce, and the diced tomatoes. Stir everything together until the meat is fully incorporated into the liquid.

Add your broken lasagna noodles on top. Press them down gently so they are mostly submerged in the liquid, but do not stir them into the meat at the bottom. Leaving the pasta on top prevents it from sinking and sticking to the heating element during the cooking cycle.

Secure the lid, set the valve to sealing, and cook on high pressure for just four minutes. Yes, four minutes is all it takes. While the pot comes to pressure and cooks, mix your cottage cheese or ricotta with parmesan in a small bowl.

When the timer beeps, do a quick pressure release by switching the valve to venting. As soon as the pin drops, open the lid. Give the soup a good stir. The noodles will be perfectly al dente. Stir in a cup of shredded mozzarella until it melts into the hot broth. Ladle the soup into bowls and top each serving with a generous spoonful of your prepared cheese mixture. If you love creamy textures like our creamy cajun chicken pasta, you will adore how this finishing touch transforms the bowl.

Common Mistakes to Avoid

Even with a simple pressure cooker recipe, a few things can go wrong. Here are the most common mistakes people make and how to fix them.

• Skipping the deglazing step and leaving browned meat bits stuck to the bottom of the pot. Always pour in a splash of broth and scrape the pot clean before pressure cooking to prevent the dreaded burn warning.
• Stirring the dry noodles into the liquid before sealing the lid. Leave the broken noodles resting on top of the broth so they do not sink and scorch against the heating element.
• Using fresh lasagna noodles instead of dried pasta. Stick to dry noodles because fresh pasta contains too much moisture and will disintegrate into a gummy paste under high pressure.
• Letting the soup sit on the warm setting for too long after cooking. The noodles will keep absorbing the broth and turn soft, so serve immediately or transfer to a separate container to halt the cooking process.
• Forgetting to break the noodles into small pieces. Break them into rough two inch shards so the soup remains easy to eat with a standard spoon.

Pro Tips for the Best Lasagna Soup in the Instant Pot

To take your quick lasagna soup recipe from good to spectacular, a few minor adjustments make a big difference. First, consider your meat ratio. While ground beef is traditional, using a mix of half ground beef and half ground pork gives the broth a richer, sweeter profile. If you want a lighter version, ground turkey works beautifully, but you should add an extra tablespoon of olive oil when browning to compensate for the lower fat content.

The way you handle your tomatoes matters. If you prefer a smoother broth, you can blend your diced tomatoes before adding them. I prefer leaving them diced for the extra texture and color they bring to the bowl. If you love the flavor profile of our italian pasta salad recipe, you will appreciate the punch of flavor that a dash of balsamic vinegar adds right at the end of cooking. Stir in one teaspoon of balsamic vinegar after the pressure releases to brighten the heavy tomato base.

Customizing Your Toppings

Do not skimp on the toppings. A bowl of this soup begs for texture. I like to serve it with a side of toasted garlic bread for dipping. You can also garnish the bowls with fresh basil leaves, extra shredded parmesan, or a drizzle of high quality olive oil. The oil adds a lovely fruity note that balances the acidity of the tomatoes.

If you are looking for other meals that come together quickly on busy nights, our 15 minutes chicken dinner is another fantastic option to keep in your back pocket. For the cheese mixture, try adding a quarter teaspoon of lemon zest to your cottage cheese or ricotta. It cuts through the heavy meat broth with a subtle, bright citrus note that makes the whole dish taste fresher. Finally, always taste the broth before serving. Depending on the saltiness of your broth and marinara, you may need an extra pinch of salt or a heavy crack of black pepper.

Storing and Reheating Leftovers

Leftovers of this deconstructed lasagna soup are incredibly delicious, but they require a specific approach if you want to preserve the pasta texture. The biggest challenge with storing soup containing pasta is that the noodles act like sponges. They will continue to soak up the broth in the refrigerator, leaving you with a thick, stew like consistency the next day.

To store leftovers, let the soup cool completely to room temperature. Transfer it to an airtight container and keep it in the refrigerator for up to four days. If you know you will have leftovers, you can actually scoop the noodles out of the broth before storing. This keeps the meat and liquid separate from the pasta, and it is the best way to keep the pasta from turning to mush.

Reheating Instructions

When you are ready to eat, reheating is simple. If you stored the noodles separately, simply warm the broth on the stove or in the microwave until simmering, then add the cold noodles to the hot liquid. They will soften slightly and warm through perfectly. If you stored everything together, you will likely need to add a splash of chicken broth or water to loosen the mixture before reheating.

Heat it in the microwave in one minute increments, stirring in between, until it is steaming hot. I do not recommend freezing this soup. The dairy and pasta do not hold up well to freezing and thawing. The mozzarella can become grainy, and the pasta loses its bite entirely. If you want a soup that freezes beautifully, try our pumpkin soup instead. For this lasagna soup, enjoy it fresh, and if you have leftovers, embrace the thicker texture. It is almost like eating a bowl of the best baked pasta you have ever had.
