Best Keto Lasagna Recipe Step-by-Step Directions:

  1. Prepare the Zucchini “Noodles”
    Lay the zucchini slices on paper towels and sprinkle lightly with salt. Let them sit for 15–20 minutes to draw out excess moisture. Pat dry thoroughly. For best results, lightly grill or bake them at 375°F (190°C) for 10 minutes to remove additional water. This prevents a watery lasagna.
  2. Cook the Meat Sauce
    In a large skillet, heat olive oil over medium heat. Add chopped onion and sauté until translucent, about 3–4 minutes. Stir in minced garlic and cook for 30 seconds until fragrant.
  3. Brown the Meat
    Add ground beef and Italian sausage to the skillet. Cook until browned and fully cooked, breaking it apart with a spoon. Drain excess fat if necessary.
  4. Add Seasonings and Sauce
    Stir in marinara sauce, basil, oregano, salt, and pepper. Simmer gently for 10–15 minutes to allow flavors to meld beautifully. Remove from heat.
  5. Prepare the Cheese Mixture
    In a bowl, combine ricotta cheese, egg, Parmesan, parsley, and 1 cup of mozzarella. Mix until smooth and creamy.
  6. Assemble the Lasagna
    Preheat oven to 375°F (190°C). In a 9×13-inch baking dish, spread a thin layer of meat sauce on the bottom.
    Add a layer of zucchini slices.
    Spread a portion of the ricotta mixture evenly.
    Add another layer of meat sauce.
    Repeat layers until ingredients are used, finishing with meat sauce on top. Sprinkle remaining mozzarella cheese generously over the surface.
  7. Bake to Perfection
    Cover loosely with foil and bake for 25 minutes. Remove foil and bake an additional 10–15 minutes, until cheese is bubbly and lightly golden.
  8. Rest Before Serving
    Allow the lasagna to rest for at least 10–15 minutes before slicing. This helps it set and makes serving easier.
  9. Serve and Enjoy
    Slice into generous portions and serve warm. Each bite offers creamy, savory, and comforting goodness—just like traditional lasagna, but without the carb-heavy pasta. 🍽️

Best Keto Lasagna Recipe Notes:

  • Eggplant slices can be substituted for zucchini for a different texture.
