I love recipes with layers. It’s one reason I made my Vegan Baked Ziti with layers, too.

And main dishes with zucchini are the best! These vegan zucchini boats are easy, healthy, and delicious.

But, back to lasagna! When you combine zucchini strips, savory red sauce, and vegan ricotta and top it with vegan mozzarella shreds, you’ve got a feast.

This zucchini lasagna vegan recipe is even better because it’s made with zucchini instead of pasta noodles. It’s a great gluten-free way to get your lasagna in!

Frequently-Asked Questions

How to make zucchini lasagna not watery?

Zucchini is a vegetable with high water content. As a result, to make your zucchini noodles, you need to minimize the water content. We do this by letting it marinate with salt, which helps extract fluids. Then we briefly bake the zucchini strips to remove even more water content.

Can zucchini lasagna be frozen?

You can freeze this dish in individual servings or the entire casserole. Use a freezer-safe container or freezer bag, and they can keep for up to 2 months.
