There are two main ways of making a gluten-free vegan lasagna. Either choose gluten-free lasagna sheets (check the box for baking time!) or go with sliced zucchini instead of grain-based lasagna sheets. Keep in mind that swapping whole grain lasagna noodles for zucchini slices will also drastically lower the calorie content of your vegan lasagna! If you don’t want that, consider adding some red lentils to the ragù for more satiating complex carbs.
