Creamy Instant Pot Lasagna Soup with Ricotta

Fourth time in a week and the ricotta is still sticking to the bottom of the pot. Honestly, I don’t even know why I’m surprised anymore. You’d think by now I’d have learned to stir more often, or maybe just use a thicker broth base so the cheese doesn’t separate into those weird, clumpy islands. But here I am, standing over my Instant Pot with a wooden spoon in one hand and a half-eaten piece of garlic bread in the other, trying to scrape the stuck-on dairy off the metal. It’s not glamorous. It’s not the kind of moment you’d see in a polished cookbook photo. It’s just me, trying to fix a mistake I keep making because I can’t stop making this soup.

I started making this creamy instant pot lasagna soup with ricotta because I wanted the flavors of a classic Italian dinner without the three-hour simmer and the laundry list of boiling pots. I wanted comfort, fast. And I got it. Too fast, apparently. Because now I’m addicted. It started as a Tuesday night experiment, something to use up some leftover Italian sausage and a jar of marinara that was sitting in the back of the fridge. I threw it all in, hit sauté, then pressure cook, and when I opened the lid, the smell was incredible. Like walking into a nonna’s kitchen in Brooklyn.

But then I added the ricotta. Big mistake. I dumped the whole tub in at once, expecting it to melt smoothly like cream cheese. It didn’t. It clumped. It looked like cottage cheese soup. I was mortified. So I ate it anyway. It tasted amazing, even if the texture was weird. The next day, I tried again. This time, I whisked the ricotta with an egg and some parmesan before adding it. Better, but still a bit grainy. Third attempt, I stirred it in on the “Keep Warm” setting, low and slow. Perfect. Creamy. Luscious.

So here we are. Day four. The obsession is real. I keep coming back to this pot because it’s the closest I can get to a real lasagna without actually making lasagna. And let’s be honest, who has time to layer noodles, sauce, and cheese for an hour? Not me. I want the result, not the labor. This soup gives me that cheesy, saucy, noodle-heavy satisfaction in a bowl. It’s hearty enough to be a main course but light enough that I don’t feel like a potato afterward.

I’m sharing this version with you because it’s the one that actually works. No clumps. No burnt cheese. Just pure, creamy, Italian-inspired comfort. If you’ve been looking for a way to get your lasagna fix without the hassle, this is it. Or, if you’re like me and just love stirring pots, this will give you plenty of opportunities to practice your technique. Either way, you’re going to love it.

Why You’ll Love This Recipe

Let’s be real for a second. Most people think soup is just a side dish. A light starter before the “real” meal. But this creamy instant pot lasagna soup with ricotta? It’s the whole show. It’s got the depth of a slow-simmered ragu, the richness of a béchamel, and the heartiness of actual pasta. It’s not just good; it’s the kind of meal that makes you close your eyes after the first bite and sigh. It’s comfort food reimagined—healthier, faster, but with the same soul-soothing satisfaction.

Here is why this recipe stands out from the crowd:

• Quick & Easy: Thanks to the Instant Pot, you go from fridge to table in under 45 minutes. That is huge. You don’t need to boil water, drain pasta, or manage multiple sauces. It’s one pot, one press of a button. Perfect for busy weeknights or when you just don’t have the energy to cook.
• Simple Ingredients: You likely already have most of this in your kitchen. Ground Italian sausage (or turkey), jarred marinara, broth, dried oregano, and ricotta. No fancy grocery trips needed. It uses pantry staples to deliver bold flavor and satisfying texture without the fuss.
• Perfect for Potlucks: This soup travels well. It reheats beautifully. If you’re bringing a dish to a neighbor’s house or a office lunch, this is a winner. It’s hearty, it’s warm, and it’s universally liked.
• Crowd-Pleaser: Kids love the noodles and cheese. Adults love the savory sausage and rich broth. It’s a win-win. I’ve served this to picky eaters and foodies alike, and everyone asks for the recipe.
• Unbelievably Delicious: The texture and flavor combo is next-level. The ricotta adds a creamy tang that balances the acidity of the tomato sauce perfectly. It’s not just another version of lasagna soup; it’s the best version because it actually tastes like lasagna.

What makes this recipe different from the rest is the technique. A lot of recipes just dump ricotta in and hope for the best. They end up with a grainy, separated mess. This method uses a tempering step and careful stirring to ensure the cheese stays smooth and creamy throughout. It’s a small detail, but it makes all the difference. It transforms the soup from a simple broth with noodles into a luxurious, restaurant-quality meal.

I’ve tested this recipe dozens of times. I’ve used different types of sausage, different brands of ricotta, even different Instant Pot models. This version is the result of all those trials. It’s chef-tested, family-approved, and rigorously vetted by my own stubborn appetite. It’s the kind of recipe that reminds you why you love cooking in the first place. It’s simple, but it’s smart. And it’s delicious.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. You don’t need anything exotic or hard to find. The beauty of this dish is how common ingredients come together to create something special. Most of these items are pantry staples or easy-to-find refrigerated items.

Here is what you’ll need to make this creamy instant pot lasagna soup with ricotta:

• Italian Sausage: I prefer sweet Italian sausage for its fennel and herb notes, but spicy works if you like heat. Use about 1 pound of raw sausage, casings removed. If you’re watching your fat intake, ground turkey or chicken works well too, just add a little extra olive oil for flavor.
• Yellow Onion: One medium onion, finely diced. This forms the flavor base of the soup. Don’t skip it. It adds sweetness and depth that salt alone can’t provide.
• Garlic: Four cloves, minced. Fresh garlic is non-negotiable here. Powdered garlic just doesn’t have the same punch. If you’re in a pinch, use a teaspoon of granulated garlic, but fresh is best.
• Marinara Sauce: One 24-ounce jar of your favorite marinara. I recommend Rao’s Homemade for its clean ingredients and balanced flavor, but any brand you love works. Look for one with no added sugar if possible.
• Chicken Broth: Three cups of low-sodium chicken broth. This adds volume and savory depth. If you prefer vegetable broth, that works too. Just make sure it’s a high-quality broth with good flavor.
• Ricotta Cheese: One 15-ounce container of whole milk ricotta. This is the star. Look for firm, small-curd ricotta for the best texture. Some brands are runny, which can make the soup watery. If yours is loose, drain it in a fine-mesh strainer for 10 minutes before using.
• Unsalted Butter: Two tablespoons. This helps sauté the aromatics and adds a rich mouthfeel to the final soup.
• Heavy Cream: Half a cup. This is optional but recommended for extra creaminess. If you want a lighter version, skip it or use half-and-half. The soup will still be delicious without it.
• Dried Oregano: One teaspoon. This gives it that classic Italian pizza flavor. If you have fresh oregano, use a tablespoon instead.
• Lasagna Noodles: Eight to ten broken pieces of uncooked lasagna noodles. Breaking them makes them fit in the pot and eat easier. You can use no-boil noodles or regular ones; both work fine here.
• Parmesan Cheese: Half a cup, freshly grated. Freshly grated melts better and tastes sharper than the pre-grated stuff in the green can. Trust me on this one.
• Salt and Black Pepper: To taste. Always season at the end so you can adjust based on the saltiness of your sausage and broth.

If you want to get fancy, you can add a pinch of red pepper flakes for heat, or a splash of balsamic vinegar for acidity. But the core ingredients listed above are all you need to make this work. Substitutions are easy: swap sausage for ground beef, or use gluten-free noodles if needed. The flexibility is part of the fun.

Equipment Needed

You don’t need a lot of fancy gear to make this soup, but having the right tools makes the process smoother. Here is what you’ll need:

• Electric Pressure Cooker: An Instant Pot is ideal here. It handles the sautéing, pressure cooking, and warming in one device. If you don’t have one, you can make this on the stovetop, but it will take longer. You’ll need a large heavy-bottomed pot for the pressure cooking step.
• Wooden Spoon: For stirring the sausage and onions. Silicone is fine too, but wood is gentle on the pot’s non-stick surface if your Instant Pot has one.
• Whisk: Essential for mixing the ricotta with the egg and parmesan before adding it to the soup. This prevents clumping.
• Measuring Cups and Spoons: Standard kitchen tools. Nothing fancy needed.
• Knife and Cutting Board: For dicing the onion and mincing the garlic.
• Fine-Mesh Strainer: Optional, but helpful if your ricotta is watery. It helps you drain the excess liquid for a thicker soup.

If you’re using a stovetop method, you’ll need a ladle for serving and a large pot. I’ve tried making this in a slow cooker too, and it works, but the texture of the ricotta isn’t as creamy. The pressure cooking helps the noodles cook perfectly in the broth, so I stick with the Instant Pot. Maintenance tip: clean your pressure cooker valve immediately after use. Sausage grease can clog it up if you let it sit.

Preparation Method

Making this creamy instant pot lasagna soup with ricotta is straightforward, but attention to detail matters. Follow these steps carefully for the best results.

1. Sauté the Aromatics (5 minutes): Turn your Instant Pot to “Sauté” mode. Add the butter and let it melt. Once foamy, add the diced onion and cook until soft and translucent, about 3-4 minutes. Add the minced garlic and cook for another 30 seconds until fragrant. Be careful not to burn the garlic. It turns bitter quickly.
2. Cook the Sausage (5 minutes): Add the ground Italian sausage to the pot. Break it up with your wooden spoon as it cooks. Cook until browned and no longer pink, about 5-6 minutes. If there’s excessive grease, you can drain some of it out, but leave a little for flavor. Stir in the dried oregano and cook for 30 seconds.
3. Build the Base (1 minute): Pour in the marinara sauce and chicken broth. Scrape the bottom of the pot with your spoon to release any browned bits (the fond). This is crucial for preventing the “burn” error. If you don’t scrape well, the pot might not come to pressure.
4. Add Noodles and Pressure Cook (8 minutes): Add the broken lasagna noodles to the pot. Stir them in so they are submerged in the liquid. Secure the lid, set the valve to “Sealing,” and pressure cook on High for 8 minutes. The noodles will cook in the broth, absorbing the flavor.
5. Natural Release (10 minutes): Once the cooking cycle is done, let the pressure release naturally for 10 minutes. Then, carefully turn the valve to “Venting” to release any remaining pressure. Do not touch the valve; steam will shoot out. Wait until the float valve drops.
6. Prepare the Ricotta Mixture (2 minutes): While the pot is releasing, take a small bowl and whisk together the ricotta cheese, one egg, half the parmesan, and a pinch of salt and pepper. This mixture will be added later to create the creamy base.
7. Combine and Warm (5 minutes): Open the lid. The soup will be thick. Stir in the heavy cream if using. Turn the Instant Pot to “Sauté” mode on Low (or just use the “Keep Warm” function). Slowly stir in the ricotta mixture, a ladleful at a time, whisking constantly. This tempering step ensures the cheese melts smoothly without curdling. Do not boil the soup after adding the ricotta, or it might split.
8. Final Seasoning and Serve: Taste the soup. Add salt and black pepper as needed. If it’s too thick, add a splash more broth. Ladle into bowls and top with extra parmesan and fresh basil if you have it.

Personal tip: If you like your noodles softer, cook for 9-10 minutes. If you prefer them al dente, stick to 8 minutes. The residual heat will continue to cook them slightly after you open the pot.

Cooking Tips & Techniques

There are a few tricks to making this soup perfect, and I’ve learned them the hard way. Here is what you need to know.

• Scrape the Bottom: I cannot stress this enough. When you add the liquid, use a silicone spatula to scrape every bit of stuck-on sausage and onion from the bottom of the pot. If any bits remain, the Instant Pot might trigger a “Burn” warning and stop cooking. It’s annoying, but easy to avoid.
• Temper the Ricotta: Never dump cold ricotta into hot soup all at once. It will shock the cheese and cause it to clump. Add it slowly, stirring constantly. If you’re worried, mix a ladle of hot soup into the ricotta bowl first to warm it up, then pour that mixture back into the pot.
• Don’t Overcook the Noodles: Lasagna noodles absorb a lot of liquid. If you make this soup ahead of time, it will thicken significantly in the fridge. You’ll need to add more broth when reheating. If you’re serving it right away, the 8-minute cook time is perfect.
• Choose the Right Ricotta: As mentioned, some ricottas are wetter than others. If yours is runny, drain it. If it’s dry, you might need a splash more cream. Taste it first. Good ricotta should be mild, creamy, and slightly sweet.
• Multitasking: Use the pressure cooking time to chop veggies or set the table. It’s a great way to save time. Just remember to have your ricotta mixture ready to go so you don’t waste time when the pot is done.

I once tried to use cottage cheese instead of ricotta because I was out. It didn’t work. The texture was too grainy and the flavor was too tangy. Stick to ricotta. It’s the right choice. Also, don’t skip the garlic. It’s the backbone of the flavor. If you’re sensitive to raw garlic, cook it longer until it’s golden, but don’t skip it.

Variations & Adaptations

This recipe is flexible. Here are a few ways to customize it based on your preferences or dietary needs.

• Vegetarian Version: Skip the sausage and use a cup of chopped mushrooms and a half-cup of white beans. Add a teaspoon of smoked paprika to give it a savory, meaty depth. The soup will still be hearty and delicious.
• Gluten-Free: Use gluten-free lasagna noodles. Most brands work well in pressure cooking, but check the package for cook times. You might need to reduce the pressure cook time to 6-7 minutes to prevent mushiness.
• Spicy Kick: Use hot Italian sausage instead of sweet. Add a teaspoon of red pepper flakes when sautéing the onions. Or, stir in a spoonful of Calabrian chili paste at the end for a complex heat.
• Lighter Option: Use ground turkey or chicken instead of pork sausage. Skip the heavy cream and use plain Greek yogurt instead. Stir the yogurt in at the very end, off the heat, to prevent curdling. It adds protein and tang.
• Veggie Boost: Add a cup of spinach or kale in the last 2 minutes of cooking. It wilts quickly and adds a nice color contrast. You can also add diced zucchini or bell peppers with the onions.

I tried making this with zucchini noodles once, but they turned to mush. Stick to traditional pasta. It’s what makes it “lasagna” soup. If you want to try other Italian soups, check out my cozy sausage potato kale soup for a different flavor profile.

Serving & Storage Suggestions

This soup is best served hot, straight from the pot. Ladle it into wide bowls so you can see all the layers. Top with a generous sprinkle of parmesan cheese and a few leaves of fresh basil. A drizzle of high-quality olive oil adds a nice finish.

• Side Dishes: Serve with crusty garlic bread or a simple green salad with vinaigrette. The acidity of the salad cuts through the richness of the soup. I also love this with a slice of honey butter skillet cornbread if you’re in a festive mood.
• Refrigerator Storage: Let the soup cool completely, then store it in an airtight container in the fridge for up to 4 days. The noodles will continue to absorb liquid, so the soup will thicken. It’s still good, just thicker.
• Freezer Storage: This soup freezes well, but the texture of the ricotta might change slightly upon thawing. It may become a bit grainy. To freeze, leave out the ricotta and cream, freeze the base soup, and add fresh ricotta when reheating. Or, freeze it all and reheat gently on the stovetop, stirring frequently.
• Reheating: Reheat on the stovetop over medium-low heat, adding a splash of broth or water to loosen it up. Microwave in intervals, stirring in between. Do not boil it, or the cheese might separate.

The flavors actually improve after a day or two. The noodles soak up more of the sauce, and the herbs meld together. It’s great for meal prep. Just remember to add extra liquid when reheating.

Nutritional Information & Benefits

This soup is a balanced meal with protein, carbs, and some fat. Here is an approximate breakdown per serving (assuming 6 servings):

• Calories: ~450
• Protein: ~25g (from sausage, ricotta, and parmesan)
• Carbs: ~35g (from noodles and marinara)
• Fat: ~20g (from sausage, cheese, and cream)

The ricotta adds calcium and protein, making it more nutritious than a standard tomato soup. The marinara provides lycopene, an antioxidant linked to heart health. If you use turkey sausage and skip the cream, you can reduce the calories and fat significantly. It’s a comfort food that can fit into a healthy diet if you watch portions. The key is the balance. It’s hearty, so one bowl is usually enough.

FAQs

Can I use no-boil lasagna noodles?

Yes, you can. No-boil noodles work perfectly in the Instant Pot. In fact, they might cook faster than regular noodles. Keep an eye on the texture after 8 minutes. If they’re still too firm, cook for 1-2 more minutes.

Why did my ricotta clump?

It likely happened because the ricotta was added too quickly to hot soup. Always temper the cheese by whisking it with a little hot soup first, then stirring it back in slowly. Also, avoid boiling the soup after adding the cheese.

Can I make this in a slow cooker?

Yes. Sauté the sausage and onions in a pan first, then add everything to the slow cooker. Cook on Low for 6-8 hours or High for 3-4 hours. Add the ricotta mixture in the last 30 minutes of cooking.

Is this soup freezer-friendly?

Yes, but the ricotta texture may change. For best results, freeze the soup base without the ricotta and cream. Add fresh ricotta when reheating.

Can I use ground beef instead of sausage?

Absolutely. Ground beef works well, but you’ll lose the fennel and herb flavor of the sausage. Add a teaspoon of Italian seasoning and a pinch of fennel seeds to compensate.
