Step‑by‑Step Instructions for Zucchini Lasagna (Keto)
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). This temperature will ensure the zucchini roasts perfectly, enhancing its flavor and texture. While your oven heats, get your baking sheet ready by lining it with parchment paper. This will make cleanup a breeze later on!
Step 2: Prepare the Zucchini
Slice your zucchinis into ⅓-inch thick rounds, aiming for approximately 16 to 18 slices. Lay these slices on the prepared baking sheet, making sure they aren’t overlapping. Brush each slice generously with olive oil and sprinkle with salt. Roast in the oven for 20 minutes until they are tender and lightly golden, which will help prevent sogginess in the lasagna.
Step 3: Cook the Meat Sauce
While the zucchini roasts, heat a skillet over medium heat and add olive oil. Sauté chopped onions and minced garlic for about 1-2 minutes until they turn translucent and fragrant. Then, add your ground meat—beef, turkey, or a vegan alternative—and cook until browned for about 8-10 minutes. Drain any excess fat to keep your sauce light and delicious.
Step 4: Simmer the Sauce
Once your meat is browned, season it with salt, pepper, and oregano to taste. Pour in your marinara sauce, stirring well to combine all the flavors. Let the mixture simmer gently on low heat for about 5-10 minutes, allowing the flavors to meld beautifully while you prepare the cheese mixture.
Step 5: Mix the Cheese Filling
In a medium bowl, combine ricotta cheese with a beaten egg and a pinch of nutmeg. Stir the mixture until it's smooth and creamy, ensuring every scoop will be flavorful. This ricotta blend is what will give your Zucchini Lasagna (Keto) that delicious, creamy texture that contrasts nicely with the savory sauce.
Step 6: Assemble the Lasagna
Grease a 9x13-inch baking dish to prevent sticking. Start by spreading ½ cup of marinara sauce on the bottom of the dish. Layer half of the roasted zucchini slices over the sauce, followed by half of the meat sauce. Spoon half of the ricotta mixture on top and gently spread it out. Repeat the layers, finishing with the remaining zucchini and marinara sauce to create a beautifully stacked lasagna.
Step 7: Bake to Perfection
Sprinkle Pecorino Romano cheese evenly over the top of your layered Zucchini Lasagna (Keto). Cover the baking dish tightly with foil and bake in the preheated oven for 20 minutes. After this time, remove the foil and continue baking for an additional 5-10 minutes until the top is golden and bubbling with delight.
Step 8: Cool and Serve
Once the lasagna has finished baking, take it out of the oven and let it rest for about 10 minutes. This resting period will allow the layers to set, making it easier to slice. Before serving, garnish with freshly chopped basil or parsley for a burst of color and flavor.

Make Ahead Options
These Keto Zucchini Lasagna make ahead options are perfect for busy weeknights! You can prepare the zucchini by slicing and roasting it up to 24 hours in advance; just refrigerate the layers to maintain quality. Similarly, you can make the meat sauce and ricotta mixture up to 3 days ahead—store them in airtight containers in the fridge. When you're ready to serve, simply layer your prepped ingredients in the baking dish, add the remaining marinara sauce, and top it with Pecorino Romano cheese. Bake as directed, and you’ll have a comforting dish that tastes just as delicious while saving you precious time!
