Easy Zucchini Lasagna Recipe layers tender zucchini, rich tomato sauce, and melty cheese into a cozy, lighter twist on classic lasagna. It suits busy weeknights, low-carb eaters, veggie lovers, and anyone who wants comfort food in about 1 hour from start to finish. I first tested this version on a hot summer night with too much garden zucchini and two hungry kids, and they both asked for seconds.
Why Choose This Easy Zucchini Lasagna Recipe
This zucchini lasagna skips the noodles, so it feels lighter but still tastes cheesy, saucy, and satisfying. You slice zucchini into thin planks, roast them to pull out moisture, then stack everything with ricotta, mozzarella, and a hearty marinara.
You still get that classic lasagna vibe, just with more vegetables and less heaviness. The recipe uses simple pantry ingredients, works with store bought shortcuts, and fits gluten free and low carb needs without feeling like a “diet” dish.

Ingredients You’ll Need
Zucchini layers
-
3 large zucchini, about 2 to 2 ½ pounds total, sliced lengthwise into ⅛ to ¼ inch planks
- Thinner slices release more moisture and layer more easily.
- Choose firm zucchini with shiny skin and no soft spots.
-
1 tablespoon olive oil
-
½ teaspoon fine sea salt
-
¼ teaspoon black pepper
Sauce layer
-
3 cups marinara sauce
- Use a thick, high quality jarred sauce like Rao’s, Barilla, or your favorite store brand.
- Choose a low sugar option if you follow a low carb plan.
-
2 cloves garlic, minced
-
½ teaspoon dried oregano
-
½ teaspoon dried basil
-
¼ teaspoon red pepper flakes (optional, for a little heat)
Cheese layer
-
1 ½ cups whole milk ricotta cheese
- Part skim ricotta also works, but whole milk tastes creamier.
-
1 large egg
-
½ cup grated Parmesan cheese
-
1 ½ cups shredded low moisture mozzarella cheese, divided
- Pre shredded mozzarella saves time and works fine.
- If you shred a block, it melts a bit smoother.
-
½ teaspoon fine sea salt
-
¼ teaspoon black pepper
-
2 tablespoons chopped fresh parsley or basil (plus extra for topping)
Optional add ins
- ½ pound lean ground turkey, chicken, or beef, browned and drained
- 1 cup sautéed mushrooms or spinach
- ¼ cup finely chopped onion, sautéed until soft
Equipment
- 9×13 inch baking dish (glass or ceramic)
- Large baking sheet with rim
- Sharp chef’s knife or mandoline for slicing zucchini
- Mixing bowls
- Silicone spatula or spoon
- Foil
- Paper towels or clean kitchen towels
- Oven mitts
- Cooling rack (helpful but optional)
Tips & Tricks
- Slice zucchini evenly so it cooks at the same rate and layers neatly.
- Roast or grill zucchini planks before layering to pull out moisture and avoid watery lasagna.
- Pat roasted zucchini dry with paper towels to remove extra liquid.
- Use a thick marinara sauce; thin sauce adds extra water.
- Mix the egg into ricotta to help the cheese layer set and slice cleanly.
- Layer lightly and avoid pressing down hard so liquid can bubble around and evaporate.
- Let the lasagna rest at least 10 to 15 minutes before cutting so it firms up.
- Use convection bake if your oven offers it, and reduce the temperature by 25 degrees to prevent over browning.
- Add a baking sheet under the dish if you fill it high; this catches any cheesy bubbles.
- Slice leftovers into individual squares before chilling so you reheat only what you need.
How to Make Easy Zucchini Lasagna Recipe
Prep the zucchini
- Preheat the oven to 425°F. Line a large baking sheet with parchment or lightly oil it.
- Trim the ends off each zucchini. Slice lengthwise into ⅛ to ¼ inch planks with a sharp knife or mandoline.
- Lay the slices in a single layer on the baking sheet. Brush with olive oil and sprinkle with salt and pepper.
- Roast 10 to 15 minutes until the zucchini looks tender and lightly golden around the edges. Flip once halfway through.
- Transfer the slices to a plate lined with paper towels. Blot the tops gently to remove extra moisture and set aside.
Make the sauce
- Lower the oven temperature to 375°F.
- Add marinara sauce to a medium saucepan over medium heat. Stir in garlic, oregano, basil, and red pepper flakes if you use them.
- Simmer 5 to 10 minutes until the sauce thickens slightly and the garlic softens. Taste and adjust seasoning with a pinch of salt if needed.
- If you use cooked meat or sautéed vegetables, stir them into the sauce at this point.
Mix the ricotta filling
- In a medium bowl, add ricotta, egg, Parmesan, 1 cup of the mozzarella, salt, pepper, and chopped parsley or basil.
- Stir until the mixture looks smooth and evenly combined.
- Taste a tiny bit and adjust salt or pepper if needed.
- Keep the ricotta mixture in the fridge while you set up the baking dish so it stays cool and thick.
Assemble the zucchini lasagna
- Spread about ½ cup of sauce across the bottom of a 9×13 inch baking dish. This prevents sticking and adds flavor to the base.
- Lay a single layer of zucchini slices over the sauce, slightly overlapping them like shingles.
- Dollop about one third of the ricotta mixture over the zucchini and spread it gently with a spatula.
- Spoon about ¾ cup of sauce over the ricotta and spread it into an even layer.
- Repeat the layers: zucchini, ricotta, sauce, until you use all the ricotta. Aim for 3 layers of zucchini if possible.
- Finish with a final layer of zucchini and the remaining sauce on top. Sprinkle the remaining ½ cup mozzarella and a little extra Parmesan if you like a more golden crust.
Bake
- Cover the baking dish loosely with foil, tenting it so the cheese does not stick.
- Bake at 375°F for 20 minutes.
- Remove the foil and bake another 15 to 20 minutes until the top looks bubbly and golden and the edges show a little browning.
- If the top needs more color, switch to broil for 1 to 2 minutes and watch closely so it does not burn.
Rest and serve
- Place the dish on a cooling rack and let the zucchini lasagna rest 10 to 15 minutes. This rest time helps the layers set and makes slicing easier.
- Slice into squares with a sharp knife. Use a spatula to lift pieces out gently.
- Sprinkle with extra fresh basil or parsley.
- Serve hot and enjoy that cheesy, saucy, veggie packed goodness.
What to Serve with Easy Zucchini Lasagna Recipe
This Easy Zucchini Lasagna Recipe pairs nicely with a simple green salad with crisp lettuce, cucumbers, and a bright vinaigrette. Add some garlic bread or toasted baguette slices if you do not count carbs and want something to soak up extra sauce. Steamed broccoli, roasted green beans, or a quick tomato cucumber salad also balance the rich cheese. Serve with sparkling water, iced tea, lemonade, or flavored seltzer for a fresh, family friendly meal.
Storage Options
- Cool leftovers to room temperature, then store in an airtight container in the fridge for up to 4 days.
- For meal prep, slice into individual portions and store each piece in its own container for easy grab and reheat lunches.
- Freeze slices tightly wrapped in plastic and then foil, or in freezer safe containers, for up to 2 months.
- Reheat in the oven at 350°F, covered, for 15 to 20 minutes from chilled or 25 to 30 minutes from frozen, until hot and bubbly.
- Use the microwave for single servings, heating in 45 to 60 second bursts until hot, and let the lasagna sit 1 minute before eating so the cheese settles.
