Use a mandoline slicer for uniform zucchini slices. Salting and draining the zucchini is crucial to avoid watery lasagna. For a vegetarian version, substitute the meat with sautéed mushrooms, lentils, or plant-based ground meat alternatives. Add red pepper flakes for subtle heat. Let the lasagna rest after baking to firm up layers. Make the sauce and slice zucchini ahead to speed up assembly. Cheese and meat alternatives can customize the recipe. This dish is naturally gluten-free and can be made dairy-free with suitable substitutes.
