Low-Carb Lasagna Soup is a cozy dish that brings all the flavors of classic lasagna in a warm bowl. Loaded with ground meat, rich tomato sauce, and cheesy goodness, it’s a comfort food win!
I love how this soup is easy to make and fills you up without the carbs! Plus, who doesn’t enjoy a little cheese sprinkled on top? It’s like a hug in a bowl! 🥣
Key Ingredients & Substitutions
Ground Beef or Italian Sausage: This is the main protein source. You can also use ground turkey or chicken for a leaner option. If you want a plant-based version, try using lentils or plant-based meat substitutes.
Crushed Tomatoes: They give the soup its rich base. If you don’t have crushed tomatoes, you can blend whole tomatoes or use diced tomatoes for a chunkier texture. Just be sure to add a little extra liquid if needed!
Ricotta Cheese: This adds creaminess to the soup. If you’re lactose intolerant or looking for a lighter option, cottage cheese can work well. You can also leave it out and add more shredded cheese if you prefer!
Broth: Using low-sodium broth helps control the saltiness. If you don’t have any broth, water can work in a pinch, but consider adding more herbs or bouillon for flavor.
Herbs: Oregano and basil enhance the classic Italian taste. If you’re out of dried herbs, fresh ones can work too! But you may want to use a bit more as dried herbs are more concentrated.
How Do I Make Sure My Soup Is Full of Flavor?
The secret to a flavorful Low-Carb Lasagna Soup is layering flavors right from the start. Here’s how to do it:
- Start by sautéing the onions. This builds the foundation of flavor. Don’t rush this step; golden, soft onions are key!
- Always add garlic after the onions to prevent burning. When garlic is added later in the cooking process, it keeps its bright flavor.
- Season the meat well as it cooks. A little salt and pepper at this stage enhance the meat’s flavor before the liquids go in.
- Let it simmer! This time allows the herbs to blend and deepen their flavors throughout the broth.
- Don’t skip the fresh garnish on top. Fresh herbs added right before serving brighten the entire dish!
Following these tips will ensure your soup is rich and satisfying, just like a comforting lasagna dish! Enjoy your cooking!

How Much Time Will You Need?
This delicious Low-Carb Lasagna Soup will take you about 15 minutes to prepare and around 20 minutes to cook. So, in just about 35 minutes, you can enjoy a warm bowl of comforting goodness!
Step-by-Step Instructions:
1. Sauté the Aromatics:
Heat olive oil in a large pot over medium heat. Add the chopped onion and sauté until it turns translucent, which should take about 4-5 minutes. This beautiful warm color releases amazing flavors.
2. Add Garlic and Meat:
Once the onions are ready, add the minced garlic, cooking for another 1-2 minutes until it’s fragrant. Now, add your ground beef or Italian sausage. Break it up with a spoon and cook until it’s browned and cooked through, about 6-8 minutes. If there’s extra fat, feel free to drain it off for a leaner soup!
3. Mix in the Ingredients:
Next, stir in the crushed tomatoes, beef or chicken broth, dried oregano, dried basil, red pepper flakes (if using), and a pinch of salt and pepper. Stir everything together and bring it to a boil.
4. Simmer the Soup:
Once it’s boiling, reduce the heat and let it simmer for about 20 minutes. This allows all those wonderful flavors to meld together beautifully!
5. Prepare the Cheese Mixture:
While the soup is simmering, take a small bowl and mix together the ricotta cheese, 1/2 cup of shredded mozzarella, and the grated Parmesan cheese. This will create a lovely creamy topping for your soup.
6. Add Optional Ingredients:
If you’d like more texture, now’s the time to stir in cauliflower rice or zucchini noodles during the last 5 minutes of cooking. This way, they’ll get warmed without getting soggy.
7. Serve and Enjoy:
Once your soup is ready, ladle it into bowls. Add a generous dollop of your cheese mixture in the center of each bowl, sprinkle with extra mozzarella and Parmesan cheese, and season with cracked black pepper. Finish with a sprinkle of freshly chopped basil or parsley!
Serve hot and enjoy all the rich, comforting flavors of lasagna without the carbs. It’s the perfect meal to warm your heart!

Can I Use Ground Turkey Instead of Beef?
Absolutely! Ground turkey is a healthier alternative and will work great in this soup. Just ensure you season it well to enhance the flavor.
How Can I Make This Soup Vegetarian?
For a vegetarian version, simply replace the ground beef with lentils or a plant-based meat substitute. You can also bulk it up with more veggies like bell peppers or mushrooms.
How Do I Store Leftovers?
Store any leftovers in an airtight container in the fridge for up to 3 days. You can reheat the soup on the stove or in the microwave. If it thickens, simply add a splash of broth or water to loosen it up.
Can I Freeze This Soup?
Yes, you can freeze the soup before adding the cheese mixture. Store it in a freezer-safe container for up to 3 months. When ready to eat, thaw in the fridge overnight and reheat, then stir in the cheese mixture before serving for the best texture!
