During the summer months when the garden is overflowing with zucchini, our menu reflects that. I love adding these fresh veggies into our diets and using up the bounty we’ve grown.
Some of our favorite ways to use zucchini are in zucchini frittatas for breakfast or sausage zucchini boats for dinner. They’re nutritious, bursting with flavor, and also great options for those who are gluten-free.
We also love sourdough chocolate zucchini muffins and zucchini bread. These are great for breakfast, with coffee, or as a dessert.
Another family favorite is this zucchini lasagna. It’s wholesome and filling, topped with bubbly, melted cheese. The texture and flavors leave you wondering why you ever needed traditional noodles.
Unless, of course, you wanted to make your own homemade sourdough pasta, then that’s a great option, too.
Serve this dish with a side of sourdough garlic bread or sourdough cheddar biscuits for a well-rounded family dinner that even the kids will love.
Why You’ll Love This Recipe
Great flavors: With fresh zucchini flavor, well-seasoned beef, and rich layers of cottage cheese (try making your own homemade cottage cheese), parmesan, and mozzarella, I find we don’t even miss the regular lasagna noodles.
Hearty and filling: With two pounds of beef, two layers of cottage cheese, and two whole zucchinis sliced into this recipe, you’ll have a high-protein meal packed with vitamins, minerals, and fiber.
Zucchini season: When zucchini season hits, it’s easy to get behind in using this plentiful vegetable. Having the option of classic dishes turned zucchini-friendly, I find that we can enjoy our harvests more without the stress of food waste.
Ingredients
Ground beef: Try to use grass-fed beef when possible, as it is a far healthier option.
Zucchini: Two medium-sized zucchini, cut longways in 1/4″ thick slices.
Mozzarella cheese: Mozzarella is a great cheese for melting on top of dishes. Have you tried making homemade mozzarella cheese yet?
Cottage cheese: Cottage cheese gives such a rich, creamy, and pleasant consistency to lasagna.
Pasta sauce: This can be your favorite jar of sauce from the store, or you can make your own.

Avoiding Watery Zucchini Lasagna
Zucchini is right around 94% water content, which if not handled correctly, can leave you with a very soupy lasagna. To avoid this, you should take time to prepare your zucchini before assembling the dish.
My favorite method is to slice the zucchini very thinly, lightly salt it, and let the slices sit for about 15 minutes on either paper towels or in a colander.
The salt helps to pull out the excess moisture in the vegetable, which can then drain through a colander or be absorbed with paper towels. Pat them dry before using them in the dish.
Tools You May Need
Mandolin, vegetable peeler, or a sharp knife
How to Make Zucchini Lasagna
Step 1: Preheat the oven to 400 degrees. Slice the zucchini very thinly, lightly salt it, and let the slices sit for about 15 minutes on either paper towels or in a colander.
Step 2: In a large cast iron skillet, brown the ground beef. I like to season mine with 1/2 teaspoon of salt while cooking.
Step 3: In another skillet, add butter, diced onion, and sliced mushrooms, sautéing until soft.
Step 4: Shred the mozzarella cheese and set aside.
Step 5: Grate the parmesan cheese. Combine grated parmesan cheese, cottage cheese, eggs, and remaining salt.
Step 6: Combine cooked onions and mushrooms, browned ground beef, and pasta sauce.
Step 7: Assemble the lasagna in a 9×13 baking dish with a layer of meat sauce, sliced zucchini, more meat sauce, half of the cheese mixture, and half the shredded cheese. Repeat these layers.
Step 8: Bake for about 30 minutes or until bubbly and cooked through. Sprinkle with chopped basil leaves, then serve.
Tips
- Prepare your zucchini noodles before assembling the lasagna.
- For a bit of a twist, you can make your own creamy pumpkin pasta sauce for a fall-inspired version.
- Substitute the cottage cheese for homemade ricotta if you’d like.
- Add chopped, fresh herbs to your cottage cheese mixture for even more flavor!
- You can use ground chicken or ground turkey with great results, if you’d like.
- If your favorite pasta sauce is watery, add a little less to the meat mixture or cook it longer in the skillet to reduce. A thin, runny sauce can make a mess of this dish.
Recipe FAQs
I recommend baking uncovered when working with zucchini noodles. Covering the dish with aluminum foil will trap moisture, and zucchini is already notoriously watery.
I arrange my lasagna so that the final layer is noodles and cheese.
An overly soft, mushy zucchini is often the result of overbaking. This recipe has a shorter bake time, allowing for the lasagna to heat through without breaking down the zucchini. The zucchini noodles should be tender, but not disintegrating.
For best results, aim for a thick sauce that won’t spill and seep throughout your dish.
No, you should keep the zucchini skin on. It is highly nutritious and has a pleasant texture when cooked.

I didn’t have mushrooms, so threw my onions in with the beef and it turned out great! Great way to use up zucchini.
I use Ricotta and use a white sauce bottom or top and a red sauce also 👍and sometimes do eggplant for the noodles that one is my family’s fav 👍
Sounds delicious!
