Some days, you just wake up craving a big ol’ slice of lasagna, and nothing else in the world will do. This zucchini lasagna is a little different from my usual beefy, noodle-packed version (also known as the best lasagna ever), but it’s just as magical and cheesy, and I love it just the same.
Instead of pasta, the layers are made with thin slices of zucchini. And while there’s no meat in sight, it’s still hearty thanks to mushrooms, spinach, and plenty of cheese. It’s the perfect recipe for when you want something a little lighter, need more vegetarian dinner ideas, or your summer garden is exploding with zucchini and you’ve officially run the gamut on zucchini recipes.
I’ve been making this lasagna for years (I even made it once on my Food Network show!), but I’ve tweaked it here and there over time to make it even better. One of the best upgrades? Cooking the zucchini before layering it in. That simple step draws out excess moisture, so your lasagna stays flavorful and cheesy—not watery. Trust me, it makes all the difference.
Can you freeze zucchini lasagna?
Yes! Just like standard lasagna recipes, this version freezes well. Be sure to assemble the lasagna in a freezer-safe baking dish, then wrap it tightly in a layer of plastic, then a layer of foil. Freeze the lasagna, unbaked, for up to three months. Let it thaw in the refrigerator overnight then bake as directed, adding a few minutes to the bake time as needed until it's hot and bubbly.

Ingredients
- 3
large zucchini (about 1 1/2 pounds)
- 1 3/4 tsp.
kosher salt
- 2 Tbsp.
olive oil
- 1
(20-ounce) package cremini mushrooms, sliced
- 2
garlic cloves, minced
- 3/4 tsp.
ground black pepper
- 15 oz.
spinach, rinsed and drained
- 3 cups
cottage cheese
- 2 Tbsp.
flat-leaf parsley, finely chopped
- 6
fresh basil leaves, cut in chiffonade (about 1 tablespoon)
- 2
large eggs, beaten
- 1 cup
freshly grated parmesan cheese (about 4 ounces)
- 1
(32-ounce) jar store-bought marinara sauce
- 1 lb.
shredded low-moisture mozzarella (about 4 cups)
Directions
- Step 1Preheat the oven to 350°F.
- Step 2Trim the ends of the zucchini. Using a knife or a mandolin, carefully slice the zucchini lengthwise into thin strips, about 1/8- to 1/4- inch thick. Place the slices on a paper towel-lined baking sheet and season with 1 teaspoon salt. Allow to sit 10 minutes before patting dry.
- Step 3Remove the paper towels, drizzle the zucchini with 1 tablespoon of the olive oil, and roast until just tender, about 10 minutes.
- Step 4Meanwhile, heat the remaining 1 tablespoon olive oil in a large skillet over medium-high heat. Add the mushrooms and sauté until lightly browned, about 10 minutes. Stir in the garlic. Add 1/4 teaspoon of the pepper, ½ teaspoon of the salt, and the spinach, a handful at a time; cook, stirring, until the liquid evaporates, 3 to 5 minutes. Remove from the heat and set aside.
- Step 5In a medium bowl, combine the cottage cheese, parsley, basil, eggs, 1/2 cup of the parmesan, and the remaining 1/2 teaspoon pepper and 1/4 teaspoon salt; stir well.
- Step 6To assemble the lasagna, spread a third of the mushroom mixture mixture over the bottom of a 13-by-9-inch baking dish. Spoon about 1 1/4 cups of the marinara sauce on top. Arrange half of the zucchini strips over the top, carefully overlapping the edges. Spoon half of the cottage cheese mixture onto the zucchini and spread to distribute evenly. Sprinkle with half of the mozzarella. Repeat the layers once. Top with the remaining mushroom mixture. Dollop on a final layer of the remaining marinara.
- Step 7Sprinkle the top of the lasagna with the remaining 1/2 cup parmesan. Bake until the lasagna is hot and bubbly, 40 to 45 minutes. Allow to stand for 35 minutes before cutting into squares.
Tip: Zucchini lasagna can be fully assembled, covered, and refrigerated up to 2 days ahead of time. Allow it to sit at room temperature for at least 30 minutes before baking as directed. The lasagna can also be wrapped in plastic and foil and frozen for up to 3 months. Let it thaw in the refrigerator overnight before baking.
