Description

This Keto Lasagna Soup is loaded with rich, cheesy flavors and hearty ground beef—without the noodles. A cozy, low-carb, high-protein meal that’s perfect for weeknights and totally gluten-free.


Ingredients

  • 1 tablespoon vegetable oil
  • 1 ½ pounds ground beef
  • 1 medium white onion, chopped
  • 6 cloves garlic, minced
  • 2 tablespoons tomato paste
  • 1 (14 oz) can crushed tomatoes
  • 2 cups tomato passata
  • 2 ½ cups low-sodium chicken broth
  • 1 teaspoon fennel seeds (optional)
  • 2 teaspoons Italian seasoning
  • 2 teaspoons onion powder
  • 1 ½ teaspoons sea salt
  • ½ teaspoon black pepper
  • 8 oz shredded mozzarella
  • ½ cup grated parmesan
  • ½ cup fresh parsley, chopped
  • Grated parmesan (for garnish)
  • Chopped parsley (for garnish)

Instructions

  1. Heat a large pot over medium-high heat and add the vegetable oil.
  2. Add the ground beef and chopped onion. Cook for 7–8 minutes, breaking up the meat until browned.
  3. Add the minced garlic and sauté for 1 minute until fragrant.
  4. Stir in the tomato paste, crushed tomatoes, tomato passata, chicken broth, fennel seeds (if using), Italian seasoning, onion powder, salt, and pepper.
  5. Bring the mixture to a boil, then reduce heat and simmer for 20 minutes to develop flavor.
  6. Remove from heat and stir in mozzarella, parmesan, and chopped parsley until melted and combined.
  7. Ladle soup into bowls and garnish with extra grated parmesan and chopped parsley before serving.

Notes

  • Use lean ground beef for a lighter version, or regular for extra richness.
  • Fennel seeds add a mild sausage-like flavor but can be omitted.
  • Make it creamier by stirring in a splash of heavy cream at the end.
  • Leftovers can be stored in the fridge for up to 4 days or frozen for up to 2 months.
