Zucchini is a versatile vegetable but sometimes it’s difficult finding new ways to use fresh seasonal zucchini. Substituting zucchini for long lasagna pasta noodles is one of my favorite ways to enjoy classic comfort food in a new way. Zucchini noodles are a great contrast in flavor and texture to wheat noodles and are perfect for anyone looking to watch their carb intake.

After slicing the zucchini into thin noodles, make a simple meat sauce with ground turkey, Italian seasonings and red pasta sauce. Layer the thinly sliced zucchini and sauce with a creamy cheese filling made from ricotta and bake with layers of cheese until fully cooked. 

This turkey zucchini lasagna is great during the summer months because it has a classic Italian lasagna flavor but won’t weigh you down!

How To Make Zucchini Lasagna

Prepare for baking: Preheat your oven to 450F. While the oven is preheating, line at least 2 baking sheets with parchment paper, and set aside for prepared zucchini slices. 

Prepare the zucchini: After washing and trimming the ends off of the zucchini, you’ll want to use a mandolin to carefully slice them into ¼ inch thick lasagna noodles. If you don’t have a mandolin, you can use a knife to thinly slice the noodles. Place the zucchini strips in a single layer divided between baking sheets. Season them with olive oil and salt, then bake the zucchini for 10 minutes. Remove from oven and set aside to cool for assembly. Reduce the oven temperature to 375 degrees F after baking zucchini.

Make the turkey red sauce: Heat a skillet over medium-high heat, and add your ground turkey and saute until it begins to brown. Then, add chopped onions and mushrooms and saute until everything is cooked through. This should take about 6-8 minutes. Season the mixture with Italian seasoning, salt, and pepper. Pour in the jar of sauce and bring it to a boil. Once it comes to a boil, turn the heat down to simmer uncovered for about 5 minutes.

Make the ricotta cheese mixture: In a mixing bowl, add the ricotta cheese along with egg, salt, pepper, and some of the mozzarella and parmesan cheese. Mix until all ingredients are well combined and the egg is distributed evenly. 

Assemble the turkey zucchini lasagna: Spread a thin layer of meat sauce on the bottom of a 13×9 baking dish that has been coated with cooking spray. Place a layer of cooked zucchini noodles on top in a single layer. Then spread half of the ricotta cheese mixture on top of the zucchini layer very carefully followed by a layer of sauce. After this initial layer, repeat with the remaining noodles, cheese, then sauce. After the final layer of noodles are on top, sprinkle with mozzarella and parmesan.

Bake and cool: Bake the layered lasagna in the oven for 40 minutes uncovered. Once removed, allow it to sit for 10-15 minutes so all of the moisture distributes properly. Cut and serve hot. 

Expert Tips

  1. When choosing zucchini for this recipe, it’s best to make sure they are all roughly the same size. This will help you make noodles that are the same size.
  2. It’s also important to choose zucchini that is not too big. While oversized zucchini looks like a good deal, it’s actually filled with more water than normal-sized zucchini which could make this recipe be too watery. 
  3. A mandolin works best when slicing the zucchini. If you do not have one, you can accomplish this type of cut very carefully with a sharp knife. 
  4. Since the zucchini noodles are delicate, be sure to take extra care when layering the sauce and cheese mixture as they can move around. To make the cheese mixture easier to spread, make sure it is at room temperature so it spreads easier. 

Variations & Substitutes

  • If you don’t enjoy ground turkey, you can swap it out for any ground meat you enjoy including ground beef, bison, chicken, or even ground lamb. 
  • To make a vegetarian zucchini lasagna, use your favorite plant-based meat crumble substitute in place of the ground beef. The Impossible brand makes a great ground beef substitute available in most grocery stores. 
  • I used cremini mushrooms in this recipe, but you can easily use your favorites such as button mushrooms, shiitake, or portobello variety. 
  • Yellow squash makes a great zucchini substitute in this recipe and can be sliced and cooked the exact same way. 
  • If you’re not a fan of zucchini or yellow squash, try making this recipe with thinly sliced eggplant instead!
  • Give this Italian classic a green flavorful twist by using pesto sauce instead of red sauce.

How do you keep lasagna from being watery?

To make sure your zucchini lasagna isn’t watery after baking you’ll want to make sure that your zucchini noodles are baked before layering them into the dish. Since zucchini is naturally full of water, it releases it when baked. Salting and baking the zucchini beforehand will help draw out as much moisture as possible. 

You can also use slightly less tomato sauce as that also can release excess moisture. For best results, always let it sit in the pan after baking to help redistribute any excess moisture.

Ingredients 

  • 1 1/2 pounds zucchini squash, (3-4 small to medium-sized)
  • 2 teaspoons kosher salt, divided
  • 1 pound ground turkey
  • 4 ounces cremini mushrooms, chopped
  • 1/4 cup chopped onion
  • 1 teaspoon Italian seasoning
  • 1/2 teaspoon black pepper, divided
  • 24 ounces pasta sauce
  • 1 cup ricotta cheese
  • 1 large egg, lightly beaten
  • 2 cups shredded mozzarella cheese, divided
  • 1/2 cup shredded Parmesan cheese, divided

Instructions

  • Preheat the oven to 450 degrees F. Line 2 baking sheets with parchment paper and set aside.
  • Trim the ends of the zucchini then, using a mandoline, slice into ¼ inch thick “lasagna noodles”. Divide the strips between the prepared baking sheets, drizzle them with olive oil, sprinkle with 1 teaspoon salt, and roast for 10 minutes. Remove the pans from the oven and set aside to cool. Reduce oven temperature to 375 degrees F after baking zucchini.
  • Meanwhile, in a large skillet, cook the ground turkey with the mushrooms and onion over medium-high heat for 6-8 minutes until fully cooked. Stir in Italian seasoning, ½ teaspoon salt, ¼ teaspoon black pepper, and pasta sauce, then bring it to a boil. Reduce heat to low and simmer, uncovered, for 5 minutes.
  • In a medium mixing bowl, combine ricotta cheese, egg, remaining salt and pepper, 1 cup of mozzarella, and ¼ cup Parmesan; mix well.
  • Spread ½ cup of meat sauce on the bottom of a 13×9-inch baking dish coated with cooking spray. Place a single layer of zucchini noodles on top, then carefully spread on half of the cheese mixture, followed by ⅓ of the meat sauce. Repeat the layers – noodles, remaining cheese, ⅓ of the sauce. Place a final layer of noodles on top, the remaining sauce, then sprinkle with the mozzarella and Parmesan.
  • Bake, uncovered, for 40 minutes. Allow the lasagna to sit for 10-15 minutes before serving.

Notes

Storing: Any leftover zucchini lasagna can be stored in the fridge for 3-4 days. Reheat it by adding it to a 325F preheated oven and cooking it uncovered for 15-20 minutes or until completely warmed through. 
Freezing: Because zucchini is a high water vegetable, it does not hold up well when freezing. Therefore, freezing is not recommended.

  1. This recipe was awesome! I’m now making it again, and bringing it to grandma’s house today for a small family gathering. I’m from the generation of The ZONE DIET , and it feels like the Keto diet is the offspring of such. Thank you for putting this recipe out there. I need to cut the carbs out so please keep these great recipes coming!

  2. Is the carb count for the whole dish or per serving? Just trying to see if I can apply this to keto lifestyle.

    • The nutritional information is calculated per serving. The dish has 6 large servings, but you can easily cut the servings back and serve with something else if you’re looking to cut the carbs. You can also cut back on the amount of sauce if you want to cut carbs. Enjoy!

  3. I was a little nervous about using zucchini at first but I didn’t even miss the noodles, so yummy!

  4. Love this! Such a great way to use zucchini.
