Ingredients You Need

Zucchini “noodles”

3 to 4 medium zucchini, about 2 to 2½ pounds total
- Choose firm zucchini with shiny skin and minimal seeds.
- Smaller to medium zucchini work best because they hold their shape and release less water.

Sauce ingredients

You can use a good jarred marinara to save time or cook a quick homemade sauce.

2 tablespoons olive oil
1 medium yellow onion, finely chopped
3 cloves garlic, minced
1 pound ground turkey, chicken, beef, or plant-based crumbles
1 jar (24 ounces) marinara sauce
- I like a simple basil marinara with no added sugar.
- Use your favorite brand that tastes good straight from the jar.
1 tablespoon tomato paste, optional but adds depth
1 teaspoon dried oregano
1 teaspoon dried basil
½ teaspoon red pepper flakes, optional for a little heat
1 teaspoon kosher salt, plus more to taste
½ teaspoon black pepper

Cheese mixture

1½ cups whole milk ricotta cheese
- Use whole milk for better texture and flavor.
1 large egg
½ cup grated Parmesan cheese
1½ cups shredded mozzarella cheese, divided
- Pre-shredded works fine here, but fresh shredded melts more smoothly.
1 teaspoon Italian seasoning
¼ teaspoon garlic powder
¼ teaspoon onion powder
¼ teaspoon salt
2 tablespoons chopped fresh parsley or basil, plus more for garnish

Optional add-ins

1 cup baby spinach, roughly chopped
½ cup sliced mushrooms
½ cup diced bell pepper
Pinch of smoked paprika for a subtle smoky note

Equipment

9×13 inch baking dish
Large skillet or Dutch oven
Sharp chef’s knife or mandoline for slicing zucchini
Cutting board
Mixing bowls
Wooden spoon or spatula
Aluminum foil
Paper towels or clean kitchen towels
Baking sheet (to place under the pan in case of bubbling)

Tips & Mistakes

Slice zucchini evenly so it cooks at the same rate and holds the layers.
Salt the zucchini slices and pat them dry so the lasagna does not turn watery.
Roast or grill zucchini slices briefly before layering if you want extra firm “noodles.”
Use a thick sauce, not a watery one, to keep the layers sturdy.
Taste the sauce and adjust salt and spices before you build the lasagna.
Let the lasagna rest at least 15 minutes after baking so it sets and slices cleanly.
Avoid overloading with sauce or cheese, which can cause sliding layers.
Use whole milk cheeses for better melt and flavor instead of fat free versions.
Place the baking dish on a sheet pan to catch any bubbling sauce.
Slice leftovers after chilling so they portion neatly for meal prep.

How to Make Easy Zucchini Lasagna Recipe

Step 1: Prep and slice the zucchini

Wash and dry the zucchini thoroughly. Trim the ends, then slice lengthwise into ⅛ to ¼ inch thick planks with a sharp knife or mandoline. Lay the slices on a large baking sheet or cutting board, sprinkle both sides lightly with salt, and let them sit 15 to 20 minutes so they release moisture.

Pat the zucchini slices very dry with paper towels or a clean kitchen towel. If you want extra firm slices, you can line a baking sheet with parchment, lay the zucchini in a single layer, and bake at 400°F for 8 to 10 minutes. Let them cool while you make the sauce.

Step 2: Sauté veggies and aromatics

Heat oil in a large stock pot or Dutch oven over medium heat. Once hot, add onions and carrots; cook until soft, about 8 minutes. Stir in garlic, ginger, harissa, coriander, and turmeric; cook 2 minutes, until aromatic. Season with salt.

Now adjust this step for the actual lasagna sauce.

Heat 2 tablespoons olive oil in a large skillet or Dutch oven over medium heat. Add the chopped onion and cook 5 to 7 minutes until it softens and turns translucent. Stir in the garlic and cook 30 to 60 seconds until it smells fragrant.

Step 3: Brown the meat and build the sauce

Add the ground turkey, chicken, beef, or plant-based crumbles to the pan. Break it up with a spoon and cook 6 to 8 minutes until it browns and no pink remains. Season with salt, pepper, oregano, basil, and red pepper flakes.

Stir in the tomato paste and cook 1 minute to toast it. Pour in the marinara sauce and stir to combine. Lower the heat and let the sauce simmer 10 to 15 minutes so it thickens slightly, then taste and adjust seasoning.

Step 4: Mix the cheese layer

In a medium bowl, add ricotta, egg, Parmesan, 1 cup of the shredded mozzarella, Italian seasoning, garlic powder, onion powder, salt, and chopped parsley or basil. Stir until the mixture looks smooth and creamy. If you use spinach, stir it into the cheese mixture now.

Set the cheese bowl aside. Keep the remaining ½ cup mozzarella for the top of the lasagna. Preheat your oven to 375°F while you assemble.

Step 5: Assemble the zucchini lasagna

Spread a thin layer of sauce on the bottom of a 9×13 inch baking dish so nothing sticks. Arrange a layer of zucchini slices over the sauce, slightly overlapping them to cover the bottom. Spoon and spread half of the ricotta mixture over the zucchini.

Top with a generous layer of sauce. Repeat with another layer of zucchini, the rest of the ricotta mixture, and more sauce. Finish with a final layer of zucchini and the remaining sauce, then sprinkle the remaining mozzarella and a little extra Parmesan on top.

Step 6: Bake

Cover the baking dish loosely with foil, tenting it slightly so the cheese does not stick. Bake at 375°F for 25 minutes. Remove the foil and bake another 15 to 20 minutes until the top turns golden and the edges bubble.

If you want deeper browning, you can broil the top for 1 to 2 minutes, but watch closely. Remove the lasagna from the oven and place the dish on a cooling rack. Let it rest 15 to 20 minutes so the layers firm up.

Step 7: Slice, garnish, and serve

Use a sharp knife to cut the lasagna into squares. Slide a spatula under each piece and lift carefully so the layers stay intact. Sprinkle with extra chopped parsley or basil.

Serve warm with your favorite sides. Enjoy the cheesy, saucy layers and the tender zucchini that stands in for noodles like a pro.

Variations I've Tried

White zucchini lasagna
Skip the tomato sauce and use a light Alfredo style sauce with sautéed mushrooms and spinach. This version tastes rich and cozy, especially with extra Parmesan on top.
Spicy Italian sausage version
Swap the ground meat for hot or mild Italian sausage and adjust the red pepper flakes. The sausage adds a ton of flavor, so you can keep the rest of the seasoning simple.
Vegetarian zucchini lasagna
Use plant-based crumbles or skip the meat entirely and bulk up the sauce with mushrooms, spinach, and diced bell pepper. The veggies give the lasagna a hearty bite without any meat.
Pesto swirl zucchini lasagna
Stir a few spoonfuls of basil pesto into the ricotta mixture. The pesto adds a bright, herby flavor that pairs perfectly with zucchini.
Extra protein cottage cheese mix
Replace half the ricotta with small curd cottage cheese and blend it briefly for a smoother texture. This trick boosts protein and still tastes creamy and satisfying.
