Key Ingredients for Zucchini Lasagna
Gathering the right ingredients is essential for a successful zucchini lasagna. You’ll need:
- 2 pounds small or medium zucchini, sliced
- 1 pound mild Italian sausage
- 1 (24-ounce) jar marinara sauce
- 3 cups ricotta cheese
- 2 large eggs
- 8 ounces mozzarella cheese, cut into cubes
- 1/4 cup fresh basil, chopped
How to Prepare Zucchini for Lasagna
Salting Zucchini to Remove Moisture
To ensure your zucchini lasagna doesn’t turn watery, salting the zucchini is key. Slice the zucchini into 1/8-inch thick strips, lay them on paper towels, and sprinkle with kosher salt. Let them sit for 20-30 minutes. This process draws out moisture, making your lasagna perfect.
Alternative Moisture Removal Methods
If you prefer other methods, you can bake the slices at 200°F for 10-15 minutes or sauté them for 2-3 minutes per side. Both options also help reduce excess moisture while keeping the zucchini tender.
Making the Zucchini Lasagna Sauce
Browning the Italian Sausage
In a large skillet, brown the Italian sausage over medium heat, breaking it apart with a spoon. This adds a wonderful depth of flavor to your sauce. Once browned, drain any excess grease.
Simmering the Marinara Sauce
Next, add minced garlic and sauté until fragrant. Pour in the marinara sauce and drained diced tomatoes, followed by oregano, salt, pepper, and basil. Let this simmer for 5-15 minutes to develop a rich, savory flavor.
Preparing the Creamy Ricotta Filling
Combining Ricotta, Eggs, and Cheese
In a medium bowl, mix together ricotta cheese, eggs, 1 cup of parmesan, and a pinch of salt and pepper. This creamy filling adds a luscious texture that beautifully complements the zucchini and sauce.
Assembling Your Zucchini Lasagna
Layering the Zucchini, Sauce, and Cheese
Preheat your oven to 375°F (190°C) and grease a 9×13 inch casserole dish. Start by spreading 1/2 cup of marinara sauce at the bottom. Layer 1/3 of the zucchini slices, followed by half of the ricotta mixture, half of the remaining marinara sauce, and half of the mozzarella cubes. Repeat the layers, finishing with the last third of zucchini slices topped with the remaining mozzarella and parmesan.
Baking and Resting Your Zucchini Lasagna
Oven Temperature and Baking Time
Bake your assembled lasagna for 45 minutes, until it’s bubbly and the cheese begins to brown beautifully. Leaving it uncovered helps evaporate moisture, ensuring a deliciously firm texture.
The Importance of Resting Lasagna

Once it’s out of the oven, let your lasagna rest for 15 minutes. This allows the layers to set, making it easier to slice and serve.
Tips for the Perfect Zucchini Lasagna
Choosing the Right Zucchini
For the best results, select small to medium zucchini, as larger ones can be tough and bitter. This ensures tender layers in your lasagna.
Preventing a Watery Lasagna
Salting the zucchini is crucial to prevent a watery lasagna. Skipping this step can lead to a soupy texture, so don’t rush it!
Cheese Choices for Lasagna
Using cubed mozzarella instead of shredded helps create melty pockets of cheese throughout your dish. It’s a small change that makes a big difference!
Adding Extra Vegetables
Feel free to enhance your lasagna by adding other thinly sliced vegetables like mushrooms or spinach. This not only boosts nutrition but adds more flavor and color.
