How to Make Zucchini Lasagna

Thin slices of zucchini drying on paper towels.

Step 1: Preheat the oven to 400 degrees Fahrenheit. 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.

Cooked ground beef in a skillet.

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.

Onions and mushrooms sauteing in a pan.

Step 3: In another skillet, add butter, diced onion, and sliced mushrooms, sautéing until soft.

Eggs, cheese, and parmesan in a bowl.

Step 4: Shred the mozzarella cheese and set aside. Grate the Parmesan cheese. Combine grated Parmesan cheese, cottage cheese, eggs, and remaining salt.

Meat, sautéed veggies, and sauce mixed together in a skillet.

Step 5: Combine cooked onions and mushrooms, the browned ground beef, and the pasta sauce.

Step 7: Bake for about 30 minutes or until bubbly and cooked through. For a more golden, browned top, optionally broil for 1–2 minutes, watching closely to prevent burning.

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.

Lisa’s Expert 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.

Zucchini Lasagna FAQs

Should I bake zucchini lasagna covered or uncovered?

I recommend baking uncovered when working with zucchini noodles. Covering the dish with aluminum foil will trap moisture, and zucchini is already notoriously watery.

Can you put raw zucchini in lasagna?

Yes, this dish is layered with raw zucchini; however, it is important to prep your zucchini beforehand to remove excess moisture. You can do this by salting it lightly and letting it rest for a few minutes on a paper towel to draw out excess moisture. You can then blot them dry and proceed to use them in the lasagna.

Why is my zucchini mushy?

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.

Should lasagna sauce be thick or thin/runny?

For best results, aim for a thick sauce that won’t spill and seep throughout your dish. I love using my homemade marinara sauce!

Should I peel the zucchini?

No, you should keep the zucchini skin on. It is highly nutritious and has a pleasant texture when cooked.

Instructions 

  • Preheat the oven to 400 degrees Fahrenheit. Slice the zucchini very thinly, lightly salt it, and let the slices sit for about 15 minutes on paper towels or in a colander.
  • In a large cast iron skillet, brown the ground beef. I like to season mine with 1/2 teaspoon of salt while cooking.

Notes

  • I don’t recommend substituting summer squash as they tend to have more and larger seeds than zucchini.
  • 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.

    I didn’t have mushrooms, so threw my onions in with the beef and it turned out great! Great way to use up zucchini.

  6. Julie Munoz says:
