Instructions

  1. Prepare cauliflower

  2. Cook the meat mixture

    Heat 1 tablespoon avocado oil in a large skillet over medium heat. Sauté diced onion until translucent, about 3-4 minutes. Add lean ground beef and cook until browned, breaking it up with a spatula, about 8-10 minutes. Season with garlic powder, onion powder, dried oregano, chili flakes (optional), salt, and pepper. Stir in 1 cup low sugar marinara sauce and simmer for 2-3 minutes to combine flavors.

    Time: PT20M

  3. Prepare ricotta mixture

    In a mixing bowl, combine ricotta cheese, 1 large egg, minced fresh garlic, onion powder, garlic powder, salt, and pepper. Mix well to create a flavorful binder layer.

  4. Preheat oven

    Preheat your oven to 350°F (175°C) to ensure it's ready for baking the lasagna.

    Time: PT10M

    Temperature: 350°F

  5. Assemble the lasagna layers

    In a 9x13 inch casserole dish, spread a thin layer of the meat mixture on the bottom. Add a layer of ricotta mixture, spreading evenly. Next, add a layer of the prepared cauliflower as the pasta substitute. Sprinkle a layer of shredded mozzarella cheese on top. Repeat layering with a thinner layer of meat, cauliflower, and mozzarella. Finish with a final layer of meat and top generously with shredded mozzarella and grated Parmesan cheese.

    Time: PT10M

  6. Bake the lasagna

    Place the assembled lasagna in the preheated oven and bake uncovered for 15 minutes, until cheese is melted and bubbly and the top is golden.
