1. Introduction to Keto Lasagna

The ketogenic diet focuses on high-fat, moderate-protein, and low-carb foods, pushing the body into a state of ketosis, where fat is burned for energy instead of carbohydrates. Traditional lasagna uses high-carb pasta sheets, making it incompatible with keto.

However, with the use of low-carb vegetable substitutes or keto-friendly lasagna sheets, you can still create indulgent lasagna recipes that fit your diet.

In this guide, we’ll cover the step-by-step process of making lasagna with keto-friendly ingredients like zucchini, cabbage, eggplant, butternut squash, and more. We’ll also explore different variations, including meat-based, vegetarian, and creative lasagna styles.

By the end, you’ll have plenty of delicious keto lasagna recipes to add to your weekly meal rotation!

2. How to Make Keto Lasagna Sheets from Scratch

Keto lasagna sheets are an excellent substitute for traditional pasta. They’re low in carbs, easy to make, and add a satisfying texture to your dish. Here’s a more detailed breakdown on how to make them.

Ingredients:

  • 4 large eggs
  • 4 oz cream cheese (softened)
  • 1 ½ cups shredded mozzarella cheese
  • ½ tsp garlic powder
  • ½ tsp onion powder
  • 1 tsp Italian seasoning

Instructions:

  1. Prepare your baking sheet: Preheat your oven to 375°F (190°C) and line a large baking sheet with parchment paper. This step is crucial, as it prevents the mixture from sticking to the pan.
  2. Mix the ingredients: In a medium-sized mixing bowl, whisk the eggs until they’re light and frothy. Add the softened cream cheese and whisk until smooth, ensuring there are no lumps. Cream cheese needs to be at room temperature for easy mixing. If it’s too cold, microwave it for about 10 seconds.
  3. Add the seasonings: Stir in the shredded mozzarella, garlic powder, onion powder, and Italian seasoning. The cheese adds structure to the lasagna sheets, while the seasonings give them a subtle flavor. Feel free to adjust the seasonings based on your preference.
  4. Spread the mixture: Pour the egg and cheese mixture onto the parchment-lined baking sheet. Use a spatula to spread it out evenly, forming a thin, smooth layer. The thinner the layer, the better the sheet will mimic pasta. Aim for about ¼ inch thickness to ensure it holds up when layered in the lasagna.
  5. Bake the sheets: Place the baking sheet in the oven and bake for 15-18 minutes, or until the mixture is firm and lightly golden. Check it around the 15-minute mark. If the edges start to brown too quickly, lower the oven temperature slightly.
  6. Cool and cut: Remove the sheet from the oven and allow it to cool completely. Once cooled, use a knife or pizza cutter to slice it into lasagna-sized strips. These homemade keto lasagna sheets will work perfectly in any of the recipes below.

Pro tip: Store extra sheets in an airtight container in the fridge for up to three days. You can also freeze them for later use by layering them with parchment paper to prevent sticking.

3. Classic Keto Lasagna Recipe

This classic lasagna recipe captures the essence of traditional lasagna but with a keto twist. Using the keto lasagna sheets from the previous recipe, this version is rich, cheesy, and comforting.

Ingredients:

  • 1 lb ground beef (or ground turkey)
  • 1 cup sugar-free marinara sauce (check labels for no added sugar)
  • 1 ½ cups ricotta cheese
  • 2 cups shredded mozzarella cheese
  • 1 egg
  • 1 tsp Italian seasoning
  • Keto lasagna sheets (from the recipe above)

Instructions:

  1. Preheat the oven: Set your oven to 375°F (190°C).
  2. Cook the beef: Heat a large skillet over medium heat. Add the ground beef and cook until browned, breaking it up with a spoon. Drain any excess fat. If you prefer a leaner option, ground turkey is a great substitute.
  3. Add marinara sauce: Once the meat is browned, stir in the marinara sauce and simmer on low for about 10 minutes. This step helps the flavors meld together. If you like your lasagna with extra sauce, feel free to add more.
  4. Prepare the ricotta mixture: In a separate bowl, mix the ricotta cheese, egg, and Italian seasoning. The egg helps bind the ricotta and makes it creamy during baking.
  5. Assemble the lasagna: In a 9×13 inch baking dish, start by spreading a thin layer of the meat sauce on the bottom. This prevents the first layer of lasagna sheets from sticking. Layer keto lasagna sheets over the sauce, followed by a layer of the ricotta mixture, then a layer of shredded mozzarella. Repeat the layers until all the ingredients are used, finishing with a layer of mozzarella on top.
  6. Bake: Cover the dish with foil and bake for 25-30 minutes. Removing the foil during the last 5 minutes will give the cheese a golden, bubbly crust.
  7. Let it rest: Once baked, allow the lasagna to rest for 10 minutes before slicing. This gives the layers time to set and makes it easier to serve.

Pro tip: You can make this lasagna ahead of time and store it in the fridge overnight. It tastes even better the next day!

4. Keto Zucchini Lasagna Recipe

  • 1 lb ground sausage
  • 1 cup sugar-free marinara sauce
  • 1 ½ cups ricotta cheese

  • Salt (to remove moisture from zucchini)

Instructions:

  1. Preheat the oven: Set your oven to 375°F (190°C).
  2. Prepare the zucchini: Slice the zucchinis lengthwise into thin strips. A mandoline slicer works best for even, thin slices. Lay the slices on a baking sheet and sprinkle them lightly with salt. Let them sit for about 10 minutes to draw out excess moisture, then pat them dry with paper towels. This step is essential to prevent your lasagna from becoming watery.
  3. Cook the sausage: In a skillet over medium heat, cook the ground sausage until browned. You can use Italian sausage for a more flavorful lasagna. Drain any excess fat, then add the marinara sauce and simmer for 5 minutes.
  4. Prepare the ricotta mixture: In a bowl, mix ricotta cheese, egg, and garlic powder.
  5. Assemble the lasagna: In a baking dish, layer zucchini strips, sausage mixture, and ricotta mixture. Repeat until all ingredients are used, finishing with a layer of shredded mozzarella cheese.

Keto lasagna is a great meal prep option because it stores and reheats well. Whether you’re cooking for the week or making a big batch for later, here are some tips:

  • Refrigeration: Store leftover lasagna in an airtight container in the fridge for up to 5 days. Reheat individual servings in the microwave for 1-2 minutes or until heated through.
  • Freezing: To freeze lasagna, allow it to cool completely, then wrap individual portions tightly in plastic wrap and place them in a freezer-safe container. You can freeze lasagna for up to 3 months. Thaw in the fridge overnight before reheating.
  • Reheating in the oven: For the best results, reheat your lasagna in the oven at 350°F (175°C) for 20-25 minutes, or until heated through.

16. Common Mistakes and How to Avoid Them

Here are a few common mistakes people make when cooking keto lasagna and how to avoid them:

  1. Not draining vegetables properly: Vegetables like zucchini, eggplant, and spinach release a lot of water when cooked. Make sure to drain or pat them dry to avoid watery lasagna.
  2. Overcooking the lasagna: Baking lasagna too long can make the cheese rubbery and dry. Stick to the recommended baking time and allow the lasagna to rest after cooking to let the layers set.
  3. Using too much sauce: While it’s tempting to add extra sauce, too much can lead to a soupy lasagna. Keep it balanced by using just enough to coat the layers.

Conclusion

Keto lasagna is an incredibly versatile and satisfying dish that can be adapted to suit your tastes and dietary needs. Whether you prefer a classic beef lasagna, a vegetarian option, or a fun Mexican-inspired version, these recipes will help you enjoy lasagna while staying on track with your low-carb goals.
