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). Using a sharp knife or mandoline, slice the zucchini lengthwise into 1/8-inch thick strips. Lay the strips on paper towels and sprinkle lightly with salt to draw out moisture. Let them sit for 15-20 minutes, then pat them thoroughly dry with more paper towels.
2. While the zucchini sweats, heat the olive oil in a large skillet over medium-high heat. Add the ground beef, onion, and garlic. Cook, breaking up the beef, until it is browned and the onion is soft. Drain any excess fat.
3. Stir the entire jar of marinara sauce into the cooked beef mixture. Reduce heat and let it simmer for 5 minutes. Season with salt and pepper to taste.
4. In a medium bowl, combine the ricotta cheese, Italian seasoning, egg, grated parmesan cheese, and chopped parsley. Mix until well blended.
5. Assemble the lasagna in a 9×13 inch baking dish coated with cooking spray. Spread a thin layer of the meat sauce on the bottom. Arrange a single layer of zucchini slices over the sauce. Spread half of the ricotta mixture over the zucchini, then sprinkle with 1/2 cup of the shredded mozzarella. Repeat the layers (meat sauce, zucchini, ricotta, mozzarella) one more time.
6. For the final layer, add the remaining meat sauce and top with the remaining 1 cup of mozzarella cheese.
7. Cover the dish tightly with aluminum foil and bake for 30 minutes. Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and golden.
8. Let the lasagna rest for 10-15 minutes before slicing and serving. This allows the layers to set for cleaner cuts.

Variations

• No-Meat Version: Simply omit the ground beef and use a hearty vegetable marinara or add a layer of sautéed mushrooms and spinach to the ricotta mixture.
• Grilled Zucchini: For a smokier flavor, grill the zucchini slices for 2-3 minutes per side before assembling to reduce moisture and add char.
• Individual Servings: Assemble the lasagna in individual oven-safe ramekins for perfectly portioned meals, adjusting the bake time down slightly.
• Cheese Swap: Try using cottage cheese (pulsed in a food processor for smoothness) instead of ricotta for a slightly different texture and flavor profile.

Tips for Success

• Dry the Zucchini Well: This is the most crucial step. Salting and thoroughly patting the zucchini dry prevents a watery lasagna.
• Let it Rest: Allowing the baked lasagna to rest before cutting is non-negotiable; it ensures the layers hold together and don’t turn into a soupy mess on your plate.
• Use a Mandoline: For even, thin zucchini slices that cook uniformly, a mandoline slicer is your best friend. Always use the guard for safety.
• Drain the Beef: Be sure to drain the excess fat from the cooked ground beef to keep the final dish from being greasy.

Storage & Reheating

Store leftover lasagna in an airtight container in the refrigerator for up to 4 days. To reheat, cover a portion with foil and warm in a 350°F oven for about 15-20 minutes, or until heated through. You can also reheat single servings in the microwave for 1-2 minutes.

FAQ

Can I make this lasagna ahead of time?

Absolutely. Assemble the lasagna completely, cover tightly, and refrigerate for up to 24 hours before baking. You may need to add 5-10 minutes to the covered baking time.

Can I freeze zucchini lasagna?

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

Do I have to salt the zucchini?

While highly recommended, you can skip it if you’re short on time. Just be extra diligent about patting the raw slices very dry with paper towels to remove as much moisture as possible.

My lasagna was watery. What happened?

This is usually caused by excess moisture from the zucchini. Next time, ensure you salt, sweat, and pat the zucchini completely dry. Letting the baked lasagna rest fully before serving also allows it to reabsorb some liquid.

Can I use no-boil lasagna noodles instead?

This recipe is specifically designed for zucchini as the noodle substitute. Adding traditional noodles would alter the liquid ratios and cooking time significantly.

What can I use instead of ground beef?

The instructions above use ground beef, but you can substitute it with ground turkey, Italian sausage, or a plant-based ground meat alternative following the same cooking steps.
