02Before you cook

Step-by-step overview

Creating Keto Lasagna Soup is straightforward and enjoyable. You’ll start by browning the sausage to build great flavor. After that, you’ll sauté aromatic onion and garlic before adding in the remaining ingredients. The real beauty of this dish is how easily everything comes together in one pot—no fuss and no mess!

What you’ll need

Here’s the ingredient list you’ll need to whip up this delicious soup:

  • 1 lb ground sausage
  • 1 onion, chopped
  • 2 cloves garlic, minced
  • 1 can diced tomatoes
  • 4 cups chicken broth
  • 2 cups zucchini, diced
  • 2 cups ricotta cheese
  • 2 cups shredded mozzarella cheese
  • 1 tsp Italian seasoning
  • Salt and pepper to taste

Feel free to experiment with substitutes—ground turkey or chicken can replace the sausage, and you could add in other low-carb veggies like bell peppers or spinach for added nutrition.
