Step-by-Step Instructions
Prepare the Zucchini Noodles:
- Wash the zucchini thoroughly. Trim off the ends.
- Using a mandoline slicer set to 1/8-inch thickness, carefully slice the zucchini lengthwise into long, thin ribbons. Alternatively, you can use a sharp knife, but this requires more patience for uniform slices.
- Lay the zucchini ribbons in a single layer on paper towels or a clean kitchen towel. Sprinkle lightly with salt. Let them sit for about 10-15 minutes to draw out excess moisture. Gently blot them dry with more paper towels. This step is crucial to prevent a watery lasagna.
Make the Meat Sauce:
- Heat the olive oil in a large skillet or Dutch oven over medium-high heat.
- Add the ground Italian sausage and cook, breaking it up with a spoon, until browned and no pink remains. Drain off any excess grease.
- Add the chopped onion to the skillet and cook until softened and translucent, about 5 minutes.
- Stir in the minced garlic and cook for another minute until fragrant.
- Pour in the crushed tomatoes. Add the dried oregano, dried basil, and red pepper flakes (if using). Season generously with salt and freshly ground black pepper.
- Bring the sauce to a simmer, then reduce the heat to low, cover, and let it simmer for at least 15-20 minutes to allow the flavors to meld. Taste and adjust seasoning as needed.
Prepare the Ricotta Mixture:
- In a medium bowl, combine the ricotta cheese, lightly beaten egg, and grated Parmesan cheese.
- Season with a pinch of salt and freshly ground black pepper. Stir until well combined.
Assemble the Lasagna:
- Preheat your oven to 375°F (190°C).
- Lightly grease a 9×13 inch baking dish.
- Spread a thin layer of the meat sauce on the bottom of the prepared baking dish. This prevents the first layer of zucchini from sticking.
- Arrange a single layer of the prepared zucchini ribbons over the sauce, overlapping them slightly.
- Spread half of the ricotta mixture evenly over the zucchini layer.
- Spoon about one-third of the remaining meat sauce over the ricotta mixture.
- Sprinkle about 1 cup of the shredded mozzarella cheese over the meat sauce.
- Repeat the layers: another layer of zucchini ribbons, the remaining ricotta mixture, another third of the meat sauce, and another cup of mozzarella cheese.
- Top with the final layer of zucchini ribbons, then spread the remaining meat sauce evenly over the top.
- Sprinkle the remaining mozzarella cheese (if any, or just ensure it’s evenly distributed) over the top layer of sauce.
Bake the Lasagna:
- Cover the baking dish tightly with aluminum foil.
- Bake for 25 minutes.
- Remove the foil and bake for another 10-15 minutes, or until the cheese is melted, bubbly, and lightly golden brown.
- Let the Keto Low Carb Zucchini Lasagna stand for about 10 minutes before slicing and serving. This allows it to set and makes it easier to cut.

Storing and Reheating Tips
- Refrigeration: Once cooled, any leftover Keto Low Carb Zucchini Lasagna can be stored in an airtight container in the refrigerator for up to 3-4 days.
- Reheating Individual Portions: For best results, reheat individual slices in the microwave on medium power until heated through. Alternatively, you can reheat in a toaster oven or a regular oven at 350°F (175°C) for about 10-15 minutes, covered with foil, until warm. This helps to maintain its texture.
- Freezing: This lasagna freezes beautifully. Let the baked lasagna cool completely. Cut into individual portions or freeze the entire dish. Wrap tightly in plastic wrap, then in aluminum foil, or place in freezer-safe containers. It can be stored in the freezer for up to 2-3 months.
- Reheating from Frozen: To reheat from frozen, it’s best to thaw it in the refrigerator overnight first. Then, follow the reheating instructions above. If reheating directly from frozen, it will take longer; cover with foil and bake at 350°F (175°C) for 45-60 minutes, or until heated through, removing foil for the last 10-15 minutes to allow the cheese to melt nicely.
