Prep & Cook Time

• Prep Time: 30 minutes
• Cook Time: 45 minutes
• Total Time: 1 hour 15 minutes
• Servings: 8

Ingredients

• 3 large zucchini
• 1 teaspoon olive oil
• 1 pound ground beef (such as 90% lean)
• 1/2 cup onion (finely chopped)
• 2 teaspoons garlic (minced)
• 24 ounce jar marinara sauce
• 16 ounces ricotta cheese
• 1/2 teaspoon Italian seasoning
• 1 egg
• 1/2 cup grated parmesan cheese
• 2 cups shredded mozzarella cheese
• 1 tablespoon parsley (chopped)
• salt and pepper to taste
• cooking spray

Instructions

1. Preheat your oven to 375°F (190°C). Spray a 9×13 inch baking dish with cooking spray.
2. Prepare the zucchini “noodles.” Trim the ends off the zucchini. Using a sharp knife or mandoline, slice them lengthwise into 1/8-inch thick strips. Lay the strips on paper towels and sprinkle lightly with salt to help draw out excess moisture. Let them sit for 15-20 minutes, then pat them thoroughly dry with more paper towels.
3. While the zucchini releases moisture, heat the olive oil in a large skillet over medium-high heat. Add the ground beef, finely chopped onion, and minced garlic. Cook, breaking up the beef with a spoon, until the meat is browned and the onion is soft. Drain any excess fat.
4. Stir the entire jar of marinara sauce into the cooked beef mixture. Reduce heat to low and let it simmer for 5 minutes. Remove from heat.
5. In a medium bowl, combine the ricotta cheese, Italian seasoning, egg, grated parmesan cheese, and chopped parsley. Season the mixture with salt and pepper to taste. Mix until well combined.
6. Begin assembling the lasagna. Spread a thin layer (about 3/4 cup) of the meat sauce on the bottom of the prepared baking dish.
7. Arrange a single layer of dried zucchini slices over the sauce, slightly overlapping.
8. Spread half of the ricotta cheese mixture evenly over the zucchini layer.
9. Sprinkle 1/3 of the shredded mozzarella cheese over the ricotta.
10. Spoon 1/3 of the remaining meat sauce over the mozzarella.
11. Repeat the layers: zucchini, the remaining ricotta mixture, another 1/3 of the mozzarella, and another 1/3 of the meat sauce.
12. For the final top layer, place the remaining zucchini slices. Spread the last of the meat sauce over them, then top with the final 1/3 of the shredded mozzarella cheese.
13. Cover the dish loosely with aluminum foil. Bake for 30 minutes. Then, remove the foil and bake for an additional 15-20 minutes, or until the cheese is bubbly and golden brown.
14. Let the lasagna rest for 10-15 minutes before slicing and serving. This allows the layers to set for cleaner slices.

Variations

• Veggie Power: Layer in thinly sliced portobello mushrooms or sautéed spinach between the zucchini layers for added vegetables.
• No-Bean Chili-Style: Swap the marinara for a 24-oz jar of your favorite tomato-based pasta sauce with a kick, like an arrabbiata, to add some spice.
• Individual Portions: Assemble the lasagna in personal-sized oven-safe dishes or large ramekins for easy portion control and a fun presentation.
• Fresh Finish: Top the baked lasagna with a handful of fresh basil leaves or a extra sprinkle of chopped parsley right before serving for a bright, fresh flavor.

Tips for Success

• Dry the Zucchini: Don’t skip the step of salting and thoroughly drying the zucchini slices. This is crucial to prevent a watery lasagna.
• Even Layers: Use a spoon or an offset spatula to spread the ricotta and sauce mixtures into thin, even layers for the best structure.
• Let it Rest: Resisting the temptation to cut into the lasagna immediately allows the juices to be reabsorbed, resulting in perfect, neat slices.
• Brown the Meat Well: Ensure you cook the ground beef until it’s well-browned and not just gray, as this builds a deeper, richer flavor in the sauce.

Storage & Reheating

Store leftover lasagna covered tightly in the refrigerator for up to 4 days. To reheat, cover a portion with foil and warm in a 350°F (175°C) oven until heated through, or microwave individual slices in 60-second intervals until hot.

FAQ

Can I make this lasagna ahead of time?

Yes, you can assemble the lasagna completely, cover it tightly, and refrigerate it for up to 24 hours before baking. You may need to add 5-10 minutes to the covered baking time if it goes into the oven cold.

My lasagna was watery. What went wrong?

The most common cause is not removing enough moisture from the zucchini. Ensure you pat the salted slices very dry with paper towels. Also, letting the baked lasagna rest before slicing is essential.

Can I use a different meat?

Absolutely. While the recipe specifies ground beef, you can easily substitute it with ground turkey, Italian sausage, or a plant-based meat alternative using the same cooking method.

Do I have to peel the zucchini?

No, the skin is edible and adds color and nutrients. Just give them a good scrub before slicing.

Can I freeze zucchini lasagna?

Yes, it freezes well. Assemble and bake it, then let it cool completely. Wrap the whole dish or individual portions tightly in plastic wrap and foil. Freeze for up to 3 months. Thaw in the refrigerator overnight before reheating.

Is there a substitute for the egg in the ricotta mixture?

The egg acts as a binder. If you need to omit it, you can, but the ricotta layer may be slightly more crumbly. You can try adding an extra tablespoon of grated parmesan to help hold it together.
