As we know, traditional lasagna noodles are loaded with carbs, so we sought a keto-friendly alternative. Lasagna has been a big part of my life, and I couldn't just give it up! The result? A delicious keto-friendly lasagna with only 5 g net carbs, achieved by replacing the noodles with zucchini and using a low-carb marinara sauce. Enjoy!
Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup.
Slice the zucchini lengthwise into thin strips, about 1/4 inch thick. If you don’t have a mandoline, use a sharp knife.
Place the zucchini slices on the baking sheet in a single layer. Brush them lightly with 2 tablespoons of olive oil and sprinkle with sea salt.
Roast the zucchini for 15-20 minutes, or until they become tender and most of the moisture is gone. Once roasted, pat the slices with paper towels to remove excess moisture.
While the zucchini roasts, heat the remaining 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the chopped garlic and sauté for about 30 seconds, or until it becomes aromatic.
Add the ground beef and cook until browned, approximately 10 minutes. Stir in the marinara sauce and cook for another 2 minutes. Season with salt and pepper as desired.
In a mixing bowl, combine the ricotta cheese with the grated Parmesan cheese. Beat in the egg until everything is well mixed.
Layering the Lasagna: Spread a layer of zucchini slices on the bottom of a casserole dish. Spoon half of the beef sauce over the zucchini, then add the ricotta mixture (using half of it). Sprinkle with one-third of the mozzarella cheese.Repeat the layers with the remaining zucchini, beef sauce, ricotta mixture, and top with the remaining mozzarella cheese.
Repeat the layers with the remaining zucchini, beef sauce, ricotta mixture, and top with the remaining mozzarella cheese.
Baking: Bake the lasagna in the preheated oven for about 20 minutes, or until the cheese is fully melted and starts to turn golden brown. For a crispier top, you can broil it for an additional 2-3 minutes.
Notes
Let the lasagna cool slightly before serving. Garnish with fresh basil if you like.
