- 1 tablespoon avocado or vegetable oil
- 1 pound Italian sausage (ground)
- ½ pound ground beef
- 1 onion (diced)
- 6 cloves garlic (minced)
- 1 (14 oz can) crushed tomatoes
- 1 (6 oz can) tomato paste
- 1 (14 oz can) tomato sauce
- 2 1/2 cups chicken broth (low sodium)

- 2 teaspoons Italian seasoning
- 1 1/2 teaspoons Kosher salt
- ½ teaspoon black pepper
- 8 oz mozzarella (shredded)
- ½ cup Parmesan cheese (grated)

How to Make Keto Lasagna Soup
Step 1: Cook the Meat and Vegetables
In a large heavy-bottom pot, heat the oil over medium-high heat until shimmering. Add the Italian sausage, ground beef, and diced onion. Cook until the meat is browned and onions are translucent—about 8 minutes. Stir in minced garlic and sauté until fragrant for about 1–2 minutes.
Step 2: Add Tomatoes and Seasonings
Next, add tomato paste, crushed tomatoes, tomato sauce, chicken broth, fennel seeds, Italian seasoning, salt, pepper, and stir well. Bring the mixture to a boil before reducing the heat to let it simmer for about 20 minutes.
Step 3: Finish with Cheese and Herbs
Remove the soup from heat. Stir in shredded mozzarella cheese, grated Parmesan cheese, and freshly chopped parsley. Continue stirring until the cheese has fully melted into the broth. Serve hot with extra Parmesan cheese and parsley on top for added flavor!
How to Serve Keto Lasagna Soup
Keto lasagna soup is a hearty and satisfying dish that can be served in various ways to enhance your dining experience. Here are some delightful serving suggestions that will complement this flavorful soup.
With Extra Cheese
- Sprinkle additional mozzarella or Parmesan cheese on top for an extra cheesy delight. This adds richness and enhances the lasagna flavor.
Fresh Herbs

Crusty Low-Carb Bread
- Serve with low-carb breadsticks or garlic bread. These are perfect for dipping into the soup and enhancing the overall meal.
Salad on the Side
- Pair with a simple green salad. A light salad with vinaigrette balances the rich flavors of the soup and adds freshness to your plate.
Avocado Slices
- Add avocado slices on top for creaminess. This healthy fat complements the soup while keeping it keto-friendly.
Sour Cream or Greek Yogurt

Common Mistakes to Avoid
Making Keto Lasagna Soup can be a delightful experience, but there are common pitfalls to watch out for.
- Skipping the browning step: Not browning the sausage and beef properly can lead to less flavor in your soup. Take your time to brown the meat until it’s fully cooked.
- Overlooking seasoning: Failing to season adequately can make your soup bland. Use salt, pepper, and Italian herbs generously to enhance flavors.
- Using low-quality cheese: Cheap cheeses may not melt well, affecting texture. Opt for high-quality mozzarella and Parmesan for a creamy finish.
- Ignoring broth quality: Using regular broth instead of low-sodium can make your soup overly salty. Choose low-sodium chicken broth for better control over seasoning.
- Not letting it simmer long enough: A rushed cooking process can lead to watery soup. Allowing it to simmer helps flavors meld beautifully.
