I get all the saucy, cheesy layers I crave from classic lasagna, with tender zucchini standing in for the noodles. It is rich, satisfying, and so good no one misses the pasta.

Jump to Recipe

I’m obsessed with this zucchini lasagna because it hits every lasagna craving without the heavy noodle situation. I get the saucy layers, the creamy ricotta, and that cheesy pull I want, but the zucchini keeps it fresh and a little lighter.

But not “diet food” lighter. More like, I can go back for another piece and still feel like I made a solid dinner choice.

The flavor is big, messy, savory, and satisfying. And the leftovers?

Honestly, I look forward to them almost as much as the first slice. No sad desk lunch here.

Zucchini keeps it lighter, but still gives you that cozy layered lasagna feel.
Kosher salt pulls out extra water, so you don’t get a soggy mess.
Olive oil adds richness and helps everything taste a little more homemade.
Ground beef or sausage brings the hearty, stick-to-your-ribs protein.
Onion adds that soft, sweet background flavor you’d miss if it vanished.
Garlic makes the whole pan smell like dinner is already winning.
Oregano and basil give it that classic Italian-style comfort.
Red pepper flakes add a tiny kick, if you’re into that.
Marinara ties everything together with saucy, tomato-packed goodness.
Ricotta, egg, and Parmesan make the creamy layer rich and sturdy.
Mozzarella gets melty, stretchy, and honestly, kind of necessary.
Plus, parsley and black pepper keep each bite fresh and balanced.
Basically, cooking spray saves you from scrubbing baked-on cheese later.

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 375°F and spray or oil a baking dish with the nonstick cooking spray or an extra tablespoon of olive oil.

2. Trim zucchini ends and slice lengthwise into 1/8 to 1/4 inch thick slices; sprinkle with 1 teaspoon kosher salt and let sit 15 to 20 minutes to draw out moisture, then pat slices dry with paper towels.

3. Heat 2 tablespoons olive oil in a large skillet over medium heat; add finely chopped onion and cook until translucent, about 3 to 4 minutes.

4. Add 1 pound ground beef or Italian sausage to the skillet and cook, breaking up meat, until browned and cooked through; add 3 minced garlic cloves, 1 teaspoon dried oregano, 1 teaspoon dried basil or 1 tablespoon fresh chopped basil, and 1/4 to 1/2 teaspoon red pepper flakes if using, and cook 1 minute more.

5. Stir in 24 ounces marinara sauce, simmer 5 to 10 minutes to meld flavors, then season with freshly ground black pepper and more kosher salt to taste.

6. In a bowl combine 15 ounces whole milk ricotta, 1 large beaten egg, 1/4 cup grated Parmesan, 1/4 cup chopped fresh parsley or 1 tablespoon dried parsley, and a pinch of freshly ground black pepper; mix until smooth.

7. Assemble the lasagna: spread a thin layer of meat sauce in the bottom of the prepared dish, then arrange a layer of zucchini slices, spoon half the ricotta mixture over the zucchini, sprinkle with one cup of shredded mozzarella, and spoon more meat sauce; repeat layers finishing with the remaining meat sauce and the remaining 1 cup shredded mozzarella on top.

8. Cover the dish with foil and bake 30 minutes, then remove foil and bake an additional 10 to 15 minutes until cheese is melted and bubbly and zucchini is tender.

9. Let the lasagna rest 10 to 15 minutes before slicing so it sets; garnish with extra chopped parsley and grated Parmesan if desired.

10. Serve warm and adjust seasoning at the table with more salt and freshly ground black pepper as needed.

Equipment Needed

1. Oven and baking dish (9×13 inch or similar), plus nonstick spray or oil
2. Large skillet or sauté pan
3. Cutting board and chef knife
4. Measuring spoons and measuring cups
5. Mixing bowls (one medium for ricotta, one for assembly)
6. Wooden spoon or heatproof spatula for browning meat and stirring sauce
7. Slotted spoon or tongs for arranging zucchini slices
8. Paper towels and a plate or sheet tray for draining zucchini
9. Aluminum foil and oven mitts for baking and safe handling

FAQ

Do I need to salt the zucchini before assembling Yes. Salting slices and letting them sit for 10 to 20 minutes draws out excess moisture; blot with paper towels so the lasagna is not watery.

How should I slice the zucchini Slice lengthwise into 1/8 to 1/4 inch thick strips using a knife or mandoline for even layers that bake through without becoming mushy.

Can I make this vegetarian Yes. Omit the beef or sausage and sauté mushrooms, lentils, or chopped eggplant with the onion and garlic, then proceed with the sauce and cheeses.

Can I assemble ahead and bake later Yes. Assemble, cover tightly, and refrigerate up to 24 hours before baking. Add a few extra minutes to the baking time if baking straight from cold.

How do I store and reheat leftovers Refrigerate in an airtight container up to 4 days. Reheat individual portions in the microwave or warm in a 350 F oven covered with foil until heated through.

Can I freeze this lasagna Yes. Freeze either unbaked or baked lasagna for up to 3 months. Thaw overnight in the fridge before baking if frozen unbaked, and add 10 to 20 minutes to the baking time if still chilled.

Incredibly Flavorful Zucchini Lasagna Recipe Substitutions and Variations

Zucchini: thinly sliced eggplant, thinly sliced yellow summer squash, or no-slice option with oven-roasted portobello caps layered like slices
1 pound lean ground beef or Italian sausage: ground turkey, crumbled Italian chicken sausage, or plant-based ground crumbles for a vegetarian option
Whole milk ricotta cheese: small-curd cottage cheese (drained or blended smooth), mascarpone for extra richness, or blended silken tofu for dairy-free
Shredded mozzarella cheese: shredded provolone, fontina, or a mild Monterey Jack as melting alternatives

Pro Tips

– Salt the zucchini early and press gently with paper towels or a clean kitchen towel to remove as much moisture as possible. This keeps the layers from becoming watery and helps the lasagna hold its shape when you slice it.

– Brown the meat well until you get little caramelized bits on the bottom of the pan. Deglazing with a splash of the marinara while scraping those bits up adds deeper, more savory flavor to the sauce.

– For a creamier cheese layer, let the ricotta sit at room temperature for 15 minutes before mixing, then fold in the egg and Parmesan gently. This prevents a grainy texture and helps the filling set without becoming rubbery.

– Keep the zucchini slices fairly uniform in thickness, about 1/8 to 1/4 inch. Thinner slices cook more quickly and make the dish easier to cut and eat, while thicker slices can stay a bit firm and make the lasagna harder to serve.

– Let the finished lasagna rest uncovered for 10 to 15 minutes after baking. That short cooling time allows the layers to firm up so you get neat slices, and it gives the flavors a chance to settle together.
