1-Step 1: Prepare and Salt the Eggplant Preheat your oven to 425°F and line three large baking sheets with parchment paper. This high temperature helps the eggplant roast quickly and develop golden edges. While the oven heats, slice your eggplants into 1/4-inch-thick vertical planks. Uniform thickness ensures even cooking throughout your low carb eggplant lasagna. Arrange the eggplant planks in a single layer on clean kitchen towels, then sprinkle generously with salt. Let them sit for 20 minutes to draw out excess moisture. This crucial step prevents your lasagna from becoming watery. According to Healthline’s guide to eggplant benefits, this technique also helps reduce any potential bitterness in the vegetable.

2-Step 2: Roast the Eggplant Slices After 20 minutes, you’ll notice beads of moisture on the eggplant surfaces. Pat them completely dry with fresh towels. Transfer the slices to your prepared baking sheets, drizzle with olive oil, and toss to coat evenly. Arrange them in a single layer with no overlapping pieces. Roast the eggplant for 20 to 25 minutes until tender and golden. Flip and rotate the pans halfway through cooking to ensure even browning. The eggplant should be soft enough to roll but not falling apart. Remove from the oven and let cool slightly while you prepare the filling.

3-Step 3: Make the Ricotta Cheese Filling While the eggplant roasts, combine the filling ingredients in a medium bowl. Mix together 2 cups of whole milk ricotta cheese, 1 beaten egg, 1/4 cup grated Parmesan, 2 cloves of minced garlic, 1 teaspoon dried oregano, 1 teaspoon lemon zest, 1/2 teaspoon salt, and black pepper to taste. Stir until all ingredients are evenly distributed. The lemon zest might seem like an unusual addition, but it brightens the rich cheese mixture and complements the eggplant beautifully. Taste the filling and adjust seasonings as needed. The mixture should be creamy and well-seasoned before you begin layering.

4-Step 4: Assemble the Lasagna Layers Brush a 9×13-inch baking dish with olive oil to prevent sticking. Spread 1/2 cup of marinara sauce evenly across the bottom. This creates a flavorful base for your first eggplant layer. Arrange roasted eggplant slices over the sauce, slightly overlapping if needed to cover the surface. Dollop half of the ricotta mixture over the eggplant and spread gently to create an even layer. Dot with another 1/2 cup of marinara sauce. Repeat with another layer of eggplant, the remaining ricotta mixture, and 1/2 cup more marinara. Finish with a final layer of eggplant slices.

5-Step 5: Add Cheese and Bake Top the final eggplant layer with 2 cups of grated mozzarella cheese and the remaining Parmesan. The generous cheese topping creates that golden, bubbly finish everyone loves in a traditional lasagna.

Bake the assembled lasagna for 30 minutes at 425°F until the cheese is browned and bubbling. If the cheese starts browning too quickly, you can loosely cover with foil for the first 20 minutes, then uncover for the final 10 minutes.

6-Step 6: Rest and Serve This might be the hardest step: let your eggplant lasagna rest for 30 minutes before slicing. This resting period allows the layers to set, making clean cuts much easier. Garnish with fresh basil leaves and a sprinkle of red pepper flakes before serving. Your patience will be rewarded with perfect, hold-their-shape servings.
