Zucchini Lasagna Ingredients
• Discover the perfect blend of goodies for your healthy zucchini lasagna!
For the Zucchini Layers
- Zucchini – Use 4-5 large zucchinis, sliced thinly to create delicious “noodles” with the perfect texture; eggplant can be a tasty substitute for variety.
For the Cheese Filling
- Ricotta Cheese – 1 cup, drained of excess liquid; whole milk ricotta enhances the creaminess but may leave a bit more moisture.
- Mozzarella Cheese – 1 lb, shredded low-moisture for that classic stretchy goodness; consider using part-skim mozzarella for a lighter option.
- Parmigiano Reggiano (Parmesan Cheese) – 3/4 cup, freshly grated; swap with Pecorino Romano for a sharper flavor punch.
- Egg – 1 large egg binds the ricotta filling; for a vegan twist, just omit this ingredient.
For the Sauce
- Tomato Sauce (Marinara) – 2 1/2 cups; for an added protein boost, feel free to substitute with a hearty bolognese sauce.
- Garlic – 3 cloves, minced for aromatic depth; feel free to adjust the amount to suit your taste.
For the Seasoning
- Fresh Basil – 1/4 cup, chopped for vibrant flavor and garnishing; dried basil works too, but use less to avoid overpowering.
- Fresh Oregano – 1/4 cup, chopped; can replace with dried oregano—just adjust the amount accordingly.
- Salt & Black Pepper – Essential seasonings to enhance the flavors of your healthy zucchini lasagna; taste as you go!
With these ingredients in hand, you’re ready to whip up a zucchini lasagna that checks all the boxes for health, taste, and satisfaction!
Step‑by‑Step Instructions for Zucchini Lasagna
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that your oven is at the perfect temperature when it’s time to bake the zucchini lasagna. While waiting for the oven to heat up, prepare your ingredients and pot any necessary tools like a 13×9-inch baking dish or a mandoline for slicing the zucchini.
Step 2: Prepare Zucchini Noodles
Using a mandoline or a sharp chef’s knife, slice the zucchini into 1/8-inch thick pieces to create your “noodles.” For added flavor, sprinkle the slices lightly with salt and let them sit for about 10 minutes. This process will draw out excess moisture, keeping your zucchini lasagna from becoming soggy.
Step 3: Bake Zucchini Slices
After the zucchini has rested, pre-bake the slices on parchment-lined baking sheets for 8-10 minutes at the same oven temperature. This step helps to further reduce moisture; you’ll know they’re ready when they appear tender but still retain their shape. Once done, allow them to cool for a moment, and pat dry with paper towels.
Step 4: Make the Ricotta Filling
In a medium mixing bowl, combine the drained ricotta cheese, 1/3 cup of grated Parmesan cheese, minced garlic, one large egg, and a pinch of salt and black pepper. Mix until you achieve a smooth, well-combined filling. This creamy mixture will be spread between the layers of zucchini in your zucchini lasagna.
Step 5: Layer the Ingredients
Spread a thin layer of marinara sauce on the bottom of your prepped 13×9-inch baking dish. Begin layering the zucchini noodles, then add a portion of the ricotta mixture, followed by a layer of shredded mozzarella. Repeat these layers until all ingredients are used, finishing with a layer of marinara sauce and a generous sprinkle of mozzarella on top.
Step 6: Bake the Zucchini Lasagna
Carefully place your assembled zucchini lasagna in the preheated oven and bake for 40-45 minutes. The top should be bubbling and golden brown when it’s ready. For an extra crispy finish, turn on the broiler for 1-2 minutes—but stay nearby to prevent burning!
Step 7: Garnish and Serve
Once out of the oven, allow the zucchini lasagna to cool for about 10 minutes before slicing. This resting time helps the layers to set beautifully. Sprinkle with fresh chopped basil before serving to add a burst of flavor and color. Enjoy this delightful dish that showcases the best of healthy comfort food!

Zucchini Lasagna Recipe FAQs
What type of zucchini should I use for the best results?
Absolutely! When selecting zucchini for your lasagna, choose firm, vibrant green zucchinis without dark spots or blemishes. Larger zucchinis are ideal for slicing into noodles. For added flavor, consider using eggplant as a substitution, which complements the dish beautifully.
How long can I store leftover zucchini lasagna in the fridge?
Leftovers are fantastic! Store your zucchini lasagna in an airtight container in the refrigerator for up to 3 days. Just reheat it in the oven at 350°F for about 15-20 minutes to enjoy the same delicious flavors when you’re ready to dig in!
Can I freeze zucchini lasagna?
Yes, you can! To freeze unbaked zucchini lasagna, wrap it tightly in plastic wrap and then in aluminum foil. It can be kept in the freezer for up to 3 months. When you’re ready to bake it, just thaw it overnight in the fridge before popping it into the oven.
What should I do if my zucchini lasagna is too watery?
Very helpful question! If your dish ends up watery, it could be due to excess moisture from the zucchini. To avoid this, make sure to sprinkle salt on the zucchini slices before baking to draw out moisture, and always pat them dry afterward. If it happens, you can let the lasagna rest for 10-15 minutes after baking to allow some of that excess liquid to evaporate.
Is this zucchini lasagna recipe suitable for those with allergies?
Definitely! For a gluten-free option, this zucchini lasagna is a perfect choice. However, it does contain dairy from the cheeses. For a dairy-free adaptation, you could substitute the ricotta and mozzarella with plant-based cheese alternatives.

Of course! You can assemble the entire dish up to a day in advance and store it covered in the refrigerator before baking. This make-ahead option is fantastic for busy weeknights.
