2 tbsp olive oil (for brushing the eggplant)

For the Meat Sauce:

1 lb ground beef (you can also use ground turkey or chicken)
2 cups sugar-free marinara sauce (check labels to ensure it's keto-friendly)
1 small onion, finely chopped
2 cloves garlic, minced
1 tsp dried Italian seasoning

For the Cheese Layer:

One cup of ricotta cheese (or, for a lighter alternative, cottage cheese)One cup of ricotta cheese (or, for a lighter alternative, cottage cheese)
1 egg (helps bind the cheese mixture)
2 cups shredded mozzarella cheese
½ cup grated Parmesan cheese
Fresh basil (optional, for garnish)

3. Step-by-Step Instructions

Step 1: Prepare the Eggplant

Slice the eggplant: Cut the eggplants lengthwise into thin slices, about ¼-inch thick. These will serve as your "noodles."
Sweat the eggplant: To prevent the eggplant from becoming too watery, lay the slices on a baking sheet or cutting board and sprinkle both sides generously with salt. Let them sit for 20-30 minutes. This helps draw out excess moisture and any bitterness.
Rinse and dry: After sweating, rinse the eggplant slices under cool water to remove the salt. Pat them dry thoroughly with paper towels.
Pre-bake the eggplant: Preheat your oven to 400°F (200°C). Lightly brush both sides of the eggplant slices with olive oil and place them in a single layer on a baking sheet. Bake for 15-20 minutes, flipping halfway through, until the eggplant is tender and slightly golden. By doing this, you can keep the lasagna from getting too wet.

Step 2: Make the Meat Sauce

Prepare the ground beef by: Heat a small amount of olive oil in a big skillet over medium heat. Add the chopped onion and minced garlic, cooking until the onion is soft and translucent (about 3-4 minutes). Then, add the ground beef and cook until browned, breaking it up into small pieces as it cooks. Drain any excess fat.
Add the marinara sauce: Stir in the sugar-free marinara sauce and Italian seasoning. Simmer the sauce for about 10 minutes to allow the flavors to meld. Season with salt and pepper to taste.

Step 3: Prepare the Cheese Mixture

Mix the ricotta and egg: In a small bowl, combine the ricotta cheese and egg. Stir until smooth and creamy. Set aside.

Step 4: Assemble the Lasagna

Layer the ingredients: In a 9x13-inch baking dish, start by spreading a thin layer of meat sauce on the bottom to prevent sticking. Follow with a layer of pre-baked eggplant slices. Spread some of the ricotta mixture over the eggplant, then sprinkle with shredded mozzarella and Parmesan.
Repeat the layers: Continue layering with meat sauce, eggplant slices, ricotta mixture, and cheeses until all the ingredients are used. Top with a layer of Parmesan and mozzarella.

Step 5: Bake the Lasagna

Bake: Cover the dish with aluminum foil and bake at 375°F (190°C) for 25-30 minutes. Take off the foil and continue baking for another ten to fifteen minutes, or until the cheese is golden brown and bubbling.
Let it rest: Allow the lasagna to cool for 10-15 minutes before slicing. This facilitates serving and helps the layers set.
Garnish: Optional but recommended—sprinkle fresh basil on top for an added burst of flavor and color.

7. Additional Tips for the Perfect Keto Eggplant Lasagna

Don’t skip sweating the eggplant: Salting the eggplant slices and letting them sit is crucial to avoid a watery lasagna. This process helps draw out moisture and ensures your lasagna holds together better.
Pre-bake the eggplant: Pre-baking the eggplant slices before assembling the lasagna helps to dry them out slightly, ensuring a better texture once baked with the sauce.
Adjust seasoning to taste: Depending on your marinara sauce, you might want to add extra herbs or spices. Feel free to adjust the Italian seasoning or add some red pepper flakes for a little kick.
Add more protein: If you're looking to increase the protein content, consider adding layers of cooked Italian sausage or mixing some spinach into the ricotta cheese mixture for extra nutrients.
Make it vegetarian: For a vegetarian version, simply omit the ground beef and use a hearty vegetable mixture instead (think mushrooms, spinach, and zucchini).
