Total Time: 1 hour 10 minutes

Ingredients

For the Zucchini Noodles

2 large zucchinis, sliced lengthwise into 1/8-inch-thick strips
1/2 teaspoon salt

For the Meat Sauce

1 pound ground beef (80-85% lean)
1 cup marinara sauce (choose a low-carb option for keto)
1/2 small onion, finely chopped
2 cloves garlic, minced
1 tablespoon olive oil
1 teaspoon Italian seasoning
Salt and pepper to taste

For the Cheese Mixture

1 cup ricotta cheese (full-fat for keto)
1 large egg
1/2 cup grated Parmesan cheese
Salt and pepper to taste

Additional Toppings

1 1/2 cups shredded mozzarella cheese
Fresh basil leaves, chopped (for garnish)

Step-by-Step Instructions

Step 1: Prepare the Zucchini

Slice the Zucchini: Using a sharp knife or mandoline, slice the zucchinis into long, thin strips resembling lasagna noodles.
Remove Excess Moisture: Place zucchini strips on a layer of paper towels and sprinkle lightly with salt. Pat dry after letting sit for 15 minutes to extract moisture. This step prevents a watery lasagna.

Step 2: Make the Meat Sauce

Sauté the Onion and Garlic: Heat olive oil in a skillet over medium heat. Add onions and garlic, cooking until fragrant, about 3 minutes.
Cook the Ground Beef: Add ground beef, breaking it into small pieces. Season with Italian seasoning, salt, and pepper. Cook until browned, about 8-10 minutes.
Add Marinara Sauce: Pour in the marinara sauce and stir well. To allow the flavours to blend, lower the heat and simmer for ten minutes.

Step 3: Prepare the Cheese Mixture

Mix Ingredients: In a medium bowl, combine ricotta cheese, Parmesan cheese, and the egg. Add salt and pepper to taste and mix until smooth.

Step 4: Layer the Lasagna

First Layer: Spread a small amount of meat sauce on the bottom of a baking dish (about 9x13 inches).
Layer the Zucchini: Place a layer of zucchini strips over the meat sauce, slightly overlapping.
Spread the Cheese Mixture: Spread a thin layer of the ricotta mixture over the zucchini.
Repeat Layers: Continue layering meat sauce, zucchini, and cheese mixture until all ingredients are used. Add a layer of mozzarella cheese to the top to finish.

Step 5: Bake the Lasagna

Preheat and Bake: Preheat the oven to 375°F (190°C). Bake the baking dish for half an hour after covering it with foil.
Uncover and Broil: Remove the foil and bake for another 10-15 minutes, until the cheese is bubbly and golden brown.

Step 6: Serve and Garnish

Rest and Slice: Let the lasagna cool for 10 minutes before slicing to help it set.
Garnish and Serve: Sprinkle with fresh basil leaves, and enjoy your delicious keto-friendly lasagna!

Choose the Right Marinara: Low-carb marinara sauce is ideal for keto. Check labels to keep sugar intake minimal.
Let It Rest: After baking, let the lasagna sit for a few minutes to make slicing easier and to help it hold its shape.
