Ingredients

Scale
  • 3 medium zucchini, thinly sliced lengthwise
  • 1 tablespoon olive oil
  • 1 pound ground beef
  • 1 small onion, chopped
  • 2 cloves garlic, minced
  • 2 cups marinara sauce (low sugar recommended)
  • 1 cup ricotta cheese
  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • 1 teaspoon Italian seasoning
  • Salt and pepper, to taste

Instructions

  1. Prepare the zucchini: Lay the thin zucchini slices on paper towels. Sprinkle lightly with salt and let them sit for 20 minutes to draw out moisture. Pat them completely dry with more paper towels. This step is key to avoiding a watery lasagna.
  2. Cook the meat sauce: Heat olive oil in a skillet over medium heat. Add ground beef and onion. Cook until the beef is browned. Drain any excess fat. Add garlic, marinara sauce, and Italian seasoning. Simmer for 10 minutes.
  3. Prepare the cheese mixture: In a bowl, combine the ricotta cheese, half of the mozzarella cheese, and salt and pepper. Mix well.
  4. Assemble the lasagna: Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish.
  5. Create the first layer: Spread a thin layer of the meat sauce on the bottom of the dish.
  6. Layer the zucchini: Arrange a layer of dried zucchini slices over the sauce, slightly overlapping them.
  7. Add cheese: Spread half of the ricotta mixture over the zucchini layer. Top with one-third of the remaining meat sauce.
  8. Repeat layers: Add another layer of zucchini, followed by the rest of the ricotta mixture, and then another layer of meat sauce.
  9. Final layer: Top with the final layer of zucchini slices. Spread the remaining meat sauce over the top and sprinkle with the remaining mozzarella and all of the Parmesan cheese.
  10. Bake: Cover the dish loosely with foil and bake for 30 minutes. Remove the foil and bake for another 10 to 15 minutes, or until the cheese is melted and bubbly.
  11. Rest: Let the keto zucchini lasagna rest for at least 15 minutes before slicing and serving. This helps the layers set firmly.

Notes

  • To guarantee a non watery zucchini lasagna, you must salt and thoroughly dry the zucchini slices before assembly.
  • For a heartier meal, substitute half the ricotta with cottage cheese or add cooked ground turkey instead of beef.
  • If you are making zucchini lasagna rolls instead, spread the ricotta mixture on the zucchini slices and roll them up before placing them in the sauce.
