How to Make This High-Protein Lasagna Soup

Making this lasagna soup couldn’t be easier. Everything comes together in one pot, and each step builds deep, comforting flavor in under 40 minutes.

Brown the meat
Heat olive oil in a large pot, then add the ground beef and let it sear undisturbed until it develops a deep golden crust. This step is key to creating that rich, slow-simmered taste. Break it apart and cook through before moving on.

Build the base
Add diced onion and minced garlic, then stir in chili flakes and tomato paste and cook until darkened and fragrant. Pour in the crushed tomatoes, broth, and balsamic vinegar. Simmer until the flavors meld and the soup smells rich and savory.

Cook the pasta and add finishing touches
Add broken lasagna noodles directly to the pot and simmer until tender. Just before serving, stir in torn fresh basil and optional heavy cream.

Top and serve
Ladle the soup into bowls and finish each serving with a generous dollop of the lemon ricotta Parmesan topping.

Other Cooking Methods

Crockpot

1. Brown the ground beef on the stovetop first to develop flavor, then transfer it to your slow cooker.
2. Add all remaining soup ingredients except the noodles, basil, and optional heavy cream.
3. Cook on Low for 6 to 7 hours or High for 3 to 4 hours.
4. In the last 30 minutes, stir in the broken lasagna noodles and cook until tender.
5. Stir in fresh basil and optional heavy cream just before serving, then top with the lemon ricotta Parmesan mixture.

Instant Pot

1. Turn on Sauté mode and brown the beef directly in the pot until golden.
2. Add onion, garlic, and tomato paste, cooking until fragrant.
3. Stir in the tomatoes, broth, seasonings, and balsamic vinegar.
4. Lock the lid and pressure cook on High for 6 minutes, then quick release.
5. Add the broken noodles and simmer on Sauté mode until tender, about 8 to 10 minutes.
6. Stir in basil and optional heavy cream before serving and finish with the ricotta topping.

Tips & Variations

• Make it dairy-free: Use dairy-free ricotta and Parmesan alternatives or leave out all together. Skip the heavy cream or replace with oat cream or coconut milk for a silky texture.
• Make it gluten-free: Swap lasagna noodles for your favorite gluten-free pasta. Keep an eye on the cooking time, as gluten-free pasta softens faster.
• Add vegetables: Stir in chopped spinach, zucchini, or mushrooms during the last few minutes of cooking for extra fiber and volume.

Storage & Meal Prep

Let the soup cool completely before storing. Keep the soup and ricotta topping separate in airtight containers in the fridge for up to 4 days.

If you plan to meal prep, store the noodles separately or slightly undercook them to prevent them from becoming soggy.

This soup isn’t ideal for freezing, as the dairy and pasta will change texture.
