- For the Cheese
- 15 ounces ricotta cheese – This creamy layer provides richness and balances the texture of the zucchini.
- 2 cups mozzarella cheese (shredded) – Melts beautifully, creating that gooey, cheesy goodness we all crave.
- 1/2 cup Parmesan cheese (grated) – Adds a nutty flavor and a delightful crust when baked.
- For the Seasoning
- 1 teaspoon dried oregano – A classic herb that complements Italian dishes wonderfully.
- 1 teaspoon dried basil – Brings warmth and an aromatic freshness to your Zucchini Lasagna.

Step-by-Step Zucchini Lasagna
1. Preheat the oven to 375°F (190°C). Slice your 3 medium zucchini thinly using a knife or mandoline, ensuring even thickness for perfect layering.
2. Sprinkle salt on the zucchini slices and let them sit for 10 minutes to draw out moisture. Pat dry with paper towels to prevent sogginess in your layers.
For the Sauce:
3. Sauté the chopped onion and minced garlic in a skillet over medium heat until translucent, about 5 minutes. This will infuse your sauce with lovely flavors.
4. Add the marinara sauce, oregano, basil, salt, and pepper to the skillet. Simmer for 5 minutes to meld the ingredients together beautifully.
5. Spread a layer of the sauce mixture on the bottom of a baking dish, creating a flavorful base for your Zucchini Lasagna.
6. Layer half of the zucchini slices over the sauce, followed by half of the ricotta cheese, half of the mozzarella cheese, and a sprinkle of Parmesan for richness.
7. Repeat the layers with the remaining zucchini slices, ricotta cheese, mozzarella cheese, and finish with another layer of sauce topped with mozzarella on top.
8. Cover the baking dish with foil and bake for 30 minutes. This helps steam the zucchini while keeping everything moist.
9. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden brown—this is where it becomes irresistible!
10. Let cool for 10 minutes before slicing and serving to enhance flavors and make it easier to cut through those delicious layers.
Optional: Drizzle with fresh basil before serving for an aromatic touch!

Tips for the Best Zucchini Lasagna
- Slicing Technique: Use a mandoline for even zucchini slices; this ensures uniform cooking and prevents sogginess.

- Layer Order: Start with sauce on the bottom to prevent sticking. This also helps the zucchini retain moisture while baking.
- Cheese Variations: Experiment with different cheeses like goat cheese or feta for added flavor. Just remember not to overload on cheese to maintain balance.
- Cooling Time: Allow the lasagna to cool for at least 10 minutes before slicing. This helps the layers set and makes serving easier.
- Overcooking Warning: Keep an eye on the lasagna during the last 10 minutes of baking; you want bubbly cheese, not burnt edges!
