  • 2 cups Mozzarella cheese, shredded (Layered on top of cauliflower and meat)
  • 0.5 cup Parmesan cheese, grated (Sprinkled on top for extra flavor)

Instructions

  1. Prepare cauliflower

    Steam the cauliflower florets until just tender, about 8-10 minutes. Then, microwave for 2 minutes to soften further if desired. Squeeze out as much moisture as possible using a clean kitchen towel or cheesecloth to prevent watery lasagna.

    Time: PT15M

  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.

    Time: PT5M

  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.

    Time: PT15M

    Temperature: 350°F
