Step-by-Step Cooking Directions

Prepare the zucchini slices
Wash the zucchinis and slice them lengthwise into thin strips using a mandoline or sharp knife. Aim for slices about ⅛ inch thick. Lay them on paper towels or a clean towel, sprinkle with salt, and let them sit for 15–20 minutes. This helps draw out excess moisture and prevents soggy lasagna. After resting, pat them dry with paper towels.

Make the meat sauce
In a large skillet, heat the olive oil over medium heat. Add the chopped onion and sauté for 3–4 minutes until translucent. Stir in the minced garlic and cook for another 30 seconds. Add the ground beef or turkey, breaking it apart with a spatula. Cook until browned and no longer pink, about 8–10 minutes. Drain excess fat if needed.
Season the meat with salt, pepper, and Italian seasoning. Pour in the marinara sauce, stir to combine, and let it simmer on low heat for 10–15 minutes while you prepare the other components.

Prepare the ricotta filling
In a medium bowl, combine the ricotta cheese, egg, Parmesan cheese, and chopped herbs if using. Mix until smooth and creamy. This mixture adds a rich, cheesy layer and helps hold everything together.

Assemble the lasagna
Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. Spread a small amount of meat sauce on the bottom of the dish.
Add a single layer of zucchini slices over the sauce. Spread one-third of the ricotta mixture on top, then spoon over one-third of the meat sauce, and sprinkle with mozzarella.
Repeat this layering two more times: zucchini, ricotta, meat sauce, mozzarella. End with a final layer of zucchini, the remaining sauce, and a generous topping of mozzarella and Parmesan.

Bake the lasagna
Cover the baking dish loosely with foil (non-stick side down) and bake for 30 minutes. Remove the foil and bake for an additional 15–20 minutes until the top is golden and bubbly.
Allow the lasagna to cool for at least 10 minutes before slicing. This helps the layers set and makes serving easier.

Garnish and serve
Garnish with fresh basil and a sprinkle of red pepper flakes if desired. Serve hot with a green salad or roasted vegetables on the side.

FAQ

1. Can I use cottage cheese instead of ricotta?

2. How do I prevent watery lasagna?
Salt and dry your zucchini slices before layering. You can also grill or roast the slices briefly before assembling.

3. Can I make this lasagna ahead of time?
Absolutely. Assemble the lasagna and refrigerate for up to 24 hours before baking. You can also bake it and reheat later.

4. Can I freeze zucchini lasagna?
Yes. Let it cool completely, then freeze in airtight containers. Reheat in the oven at 350°F until warmed through.

5. What type of zucchini is best?
Choose firm, medium-sized zucchini with thin skin and fewer seeds. Avoid overly large zucchini, as they tend to be watery.

6. Can I add more vegetables?
