Step‑by‑Step Instructions for Zucchini Lasagna
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This step is crucial, as it ensures the perfect cooking environment for your low-carb zucchini lasagna. While your oven heats up, you can gather all your ingredients and tools, making the preparation smoother and more enjoyable.
Step 2: Prepare Zucchini Noodles
Using a mandoline slicer or a sharp chef’s knife, carefully slice 4-5 large zucchinis into thin, 1/8 inch rounds. Once sliced, sprinkle the zucchini generously with salt and let the pieces rest on paper towels for about 10 minutes. This will help draw out excess moisture, preventing your lasagna from becoming soggy.
Step 3: Pre-Bake the Zucchini
After 10 minutes, pre-bake your zucchini slices to further reduce moisture. Spread the salted zucchini on a baking sheet lined with parchment paper and bake in the preheated oven for 10 minutes. Once done, remove it from the oven and pat the zucchini slices dry with paper towels to absorb any lingering moisture.
Step 4: Mix the Ricotta Filling
In a mixing bowl, combine about 15 ounces of ricotta cheese with grated Parmigiano Reggiano, minced garlic, 1 beaten egg, salt, pepper, and a handful of fresh basil. Stir until smooth and creamy, ensuring all ingredients are well incorporated. This mixture will form the delicious, rich filling for your zucchini lasagna.
Step 5: Layer the Lasagna
In a 13×9 inch baking dish, start layering your zucchini lasagna. Begin with a generous layer of marinara sauce on the bottom. Next, add a layer of zucchini slices, followed by a layer of the ricotta mixture, and a sprinkle of mozzarella. Repeat these layers until you’ve used all your ingredients, finishing with the last layer of marinara sauce and mozzarella on top.
Step 6: Bake the Zucchini Lasagna
Cover the assembled zucchini lasagna with aluminum foil and place it in the oven. Bake for 40-45 minutes, allowing all the flavors to meld together beautifully. To finish, you can uncover and broil the lasagna on HIGH for the last 1-2 minutes to achieve a golden, bubbly cheese topping.
Step 7: Cool and Serve
Once baked, carefully remove the zucchini lasagna from the oven and let it cool for about 10 minutes. This resting period allows the layers to set, making it easier to slice. Serve warm, garnished with extra fresh basil for an aromatic touch. Enjoy your hearty and delicious low-carb zucchini lasagna!

Zucchini Lasagna Recipe FAQs
How do I select ripe zucchini for my lasagna?
Absolutely! Look for zucchini that feels firm and has a vibrant green color. Avoid any with soft spots or dark blemishes, which may indicate overripeness. Ideally, select zucchinis that are medium-sized, around 6 to 7 inches long, as they tend to be more flavorful and have fewer seeds.
How should I store leftover zucchini lasagna?
Very! Store any leftover zucchini lasagna in an airtight container in the refrigerator for up to 3 days. To keep the layers intact, I recommend using parchment paper between layers if your dish allows it. This layering helps prevent sogginess while maintaining that delicious flavor.
Can I freeze zucchini lasagna?
Absolutely! To freeze, let the zucchini lasagna cool completely after baking. Then, wrap individual portions tightly in plastic wrap and place them in a freezer-safe bag. It will stay fresh for up to 3 months. When ready to enjoy, thaw overnight in the fridge, then reheat at 350°F for 30-40 minutes until heated through.
What should I do if my zucchini lasagna turns out watery?
Don’t worry; this can happen! To avoid this issue in the first place, make sure to salt the zucchini and let it sit to draw out moisture before baking. If your lasagna ends up watery, you can try baking it a bit longer uncovered to help evaporate the liquid. Additionally, consider pre-baking the zucchini slices a little longer if they still seem too wet.
Is this zucchini lasagna safe for people with gluten allergies?
Very! This recipe uses zucchini instead of traditional pasta, making it a great gluten-free option. However, be sure to check the labels of any store-bought marinara sauce or cheese for hidden gluten ingredients, just to be safe!
Can I make zucchini lasagna in advance?
Yes! You can assemble your zucchini lasagna the night before and store it in the fridge before baking. Just cover it tightly with foil to prevent drying out. When you’re ready to bake, simply add a few extra minutes to the cooking time, as it’ll be starting from a colder temperature. Enjoy your meal prep!
