Step-by-Step Cooking Instructions

1. Prepare the zucchini layers
   Start by slicing the zucchini lengthwise into thin strips using a mandoline or a sharp knife. Lay the slices on a paper towel, sprinkle with salt, and let them sit for 10 to 15 minutes to draw out moisture. Pat dry to remove excess water. You can also lightly grill or bake them for five minutes to prevent sogginess in the final dish.
2. Cook the meat sauce
   Heat olive oil in a large skillet over medium heat. Add minced garlic and sauté until fragrant. Add the ground beef and cook until browned, breaking it apart as it cooks. Drain excess fat if needed. Stir in the marinara sauce and Italian seasoning. Let it simmer on low heat for about 10 minutes.
3. Mix the cheese filling
   In a bowl, combine ricotta cheese, one egg, half of the parmesan, salt, and pepper. Mix until smooth and creamy. This mixture adds richness and structure to the lasagna.
4. Preheat the oven
   Set your oven to 375°F (190°C) while you begin assembling the layers.
5. Assemble the lasagna
   In a baking dish, start with a thin layer of the meat sauce. Add a layer of zucchini slices, followed by dollops of the ricotta mixture spread evenly. Sprinkle mozzarella on top. Repeat the layers until all ingredients are used, ending with meat sauce and a generous sprinkle of mozzarella and the remaining parmesan.Fans of this recipe will definitely enjoy One Pot Lasagna too.
6. Bake until bubbly
   Cover the dish with foil and bake for 25 minutes. Remove the foil and bake for another 10 to 15 minutes until the top is golden and bubbly.
7. Let it rest
   Remove from the oven and allow it to cool for 10 minutes. This step helps the layers set and makes slicing easier.

Tips for Customizing the Recipe

Keto lasagna can be adapted in countless ways to match your preferences:

• Swap the zucchini: Use eggplant slices, palmini (hearts of palm), or low-carb tortillas as the noodle substitute.
• Make it spicy: Add crushed red pepper flakes or chopped jalapeños to the meat sauce for extra heat.
• Use different meats: Ground turkey, Italian sausage, or a blend of beef and pork adds variety to the flavor profile.
• Add vegetables: Mushrooms, spinach, or bell peppers can be layered in for added nutrients.
• Dairy-free option: Use almond-based ricotta and vegan mozzarella for a dairy-free version.

Serving Suggestions

Keto lasagna is filling on its own, but it pairs well with a few low-carb sides if you want to round out your meal:

• A fresh arugula or spinach salad with olive oil and lemon dressing
• Garlic-roasted cauliflower or broccoli
• Zoodles tossed in pesto for an extra Italian vibe
• Keto garlic bread made with almond flour or fathead dough

For beverages, a dry red wine in moderation can work within some keto plans, or stick with sparkling water infused with herbs or citrus.
