Instructions
Preheat the oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Prepare the zucchini
Slice zucchini thinly lengthwise. Lightly sprinkle with salt and let sit for 5–10 minutes to remove excess moisture. Pat dry with a paper towel.
Sauté the spinach
In a skillet, heat olive oil over medium heat. Add minced garlic and cook for 30 seconds until fragrant. Add spinach, season with salt and pepper, and sauté until wilted, about 3–4 minutes. Remove from heat.
Mix the ricotta layer
In a bowl, combine ricotta cheese, 1 cup mozzarella, Parmesan, egg, nutmeg, salt, and pepper. Stir until smooth.
Prepare the tomato sauce
Mix tomato sauce with oregano, basil, garlic powder, salt, and pepper. Adjust seasoning to taste.
Layer the lasagna
Spread a thin layer of tomato sauce on the bottom of the baking dish. Place a layer of zucchini slices on top. Spread half of the ricotta mixture, then half of the sautéed spinach. Repeat layers, finishing with zucchini slices on top.
Top with cheese
Spread remaining tomato sauce over the top layer of zucchini. Sprinkle with remaining mozzarella and extra Parmesan.
Cover and bake
Cover with foil and bake for 25 minutes.
Uncover and finish baking
Remove foil and bake an additional 10–15 minutes until the top is golden and bubbly.
Cool and serve
Let the lasagna rest for 10 minutes before slicing. Garnish with fresh basil and extra Parmesan if desired. Serve warm.
