Simple Ingredients

NOODLES: Zucchini lasagna noodles are easy to make. Any size zucchini will do, however, this is a great way to use up those large zucchini from the garden! Simply slice the zucchini thin, about 1/4 inch thick for perfect squash noodles. A mandolin will help ensure the zucchini are evenly sliced. Too much zucchini? Use the rest to make some tasty zoodles and freeze for later!

SAUCE: This pasta sauce is made from ground beef and sausage, pasta sauce and diced tomatoes, with a sprinkling of Italian seasoning. After cooking the meat, make sure to drain off any extra fat.

CHEESE: There are three types of cheese in this casserole – ricotta, parmesan, and mozzarella. Ricotta is a smooth cheese that will add a layer of creaminess to the dish. The final mozzarella topping is so cheesy and golden brown.

Easy Variations

  • Zucchini can be replaced with slices of eggplant to create an eggplant lasagna! Or use the thinly sliced zucchini and roll it instead of layering for some tasty zucchini lasagna roll ups! Or hollow out zucchini and make some fun Keto lasagna zucchini boats.
  • Replace the ground beef or sausage with shredded chicken or leftover turkey for a tasty variation.
  • Cottage cheese is a great substitute for ricotta cheese, while mozzarella could be substituted with Monteray Jack or fresh mozzarella.
  • Create a vegetarian lasagna! Simply omit the meat and replace it with some mushrooms, kale, and other vegetables.

    We’ve made this twice, now, and we love it. I’m wondering if the one zucchini is if it’s those really large ones. I find I need about 4 of the smallish ones from the grocery store. I also found that salting the zucchini before cooking it gave the dish an overall tastier flavor. Otherwise, the zucchini tasted bland even with all of the other ingredients. I made no other changes, and it was delicious. My husband is on a low-carb diet, so finding tasty, satisfying dishes for him has been key to his success. Thank for sharing!

    1. It was a large zucchini Sandi! Glad you were able to find some that worked for you! Great addition, glad you and your husband can both enjoy this tasty recipe!

  2. 5 stars
    Great recipe. Though if you are buying regular grocery store zucchini you will need about four of them. I also ended up using a full 24 oz jar of roasted garlic spaghetti sauce and the full 10 oz can of diced tomatoes with green chilies.

    1. So happy you enjoyed this recipe, Claire. My garden zucchini definitely outgrow grocery store zucchini too!
