Cook Time 40 minutes minutes

Total Time 1 hour hour

Servings 8 servings

Ingredients

• Zucchini: 3–4 medium zucchini, firm and evenly sized for consistent slices.
• Olive oil: For roasting the zucchini and sautéing the aromatics.
• Ground meat: 1 pound ground turkey, chicken, beef, or Italian sausage.
• Onion and garlic: 1 small onion, finely chopped, and 3 cloves garlic, minced.
• Tomato sauce: 2 cups marinara or crushed tomatoes (no sugar added preferred).
• Tomato paste: 1 tablespoon to thicken and deepen flavor.
• Italian seasoning: 2 teaspoons, plus extra basil or oregano to taste.
• Red pepper flakes: Optional, for a gentle kick.
• Ricotta cheese: 1 1/2 cups whole-milk ricotta for creaminess.
• Egg: 1 large egg to bind the ricotta mixture.
• Parmesan: 1/2 cup grated, divided between layers and topping.
• Mozzarella: 2 cups shredded, for that classic stretch.
• Fresh basil or parsley: Chopped, for brightness.
• Salt and black pepper: To season each component.

Instructions

• Prep the zucchini “noodles”: Preheat the oven to 400°F (200°C).Slice zucchini lengthwise into 1/8–1/4-inch thick planks using a knife or mandoline. Lay them on paper towels, sprinkle lightly with salt, and let sit 15 minutes to draw out moisture.
• Roast the slices: Pat the zucchini dry, brush lightly with olive oil, and arrange on two lined baking sheets. Roast for 10–12 minutes, flipping halfway, until pliable and lightly golden.This step prevents watery lasagna.
• Make the meat sauce: Heat a tablespoon of olive oil in a large skillet over medium heat. Sauté onion until translucent, about 3–4 minutes. Add garlic and cook 30 seconds.Add ground meat, breaking it up as it browns. Season with salt, pepper, Italian seasoning, and red pepper flakes if using.
• Finish the sauce: Stir in tomato paste and cook 1 minute. Add marinara, reduce heat, and simmer 8–10 minutes until slightly thickened.Taste and adjust seasoning.
• Mix the ricotta layer: In a bowl, combine ricotta, egg, half the Parmesan, a pinch of salt and pepper, and a tablespoon of chopped basil or parsley. Stir until smooth.
• Assemble the lasagna: Lower oven to 375°F (190°C). In a 9x13-inch baking dish, spread a thin layer of meat sauce.Add a single layer of zucchini slices, slightly overlapping. Dollop and spread a third of the ricotta mixture, sprinkle with mozzarella, then add sauce. Repeat layers—zucchini, ricotta, mozzarella, sauce—until you run out, finishing with sauce and the remaining mozzarella and Parmesan.
• Bake: Cover loosely with foil (tented so it doesn’t touch the cheese) and bake 20 minutes.Uncover and bake another 10–15 minutes, until bubbly and golden on top.
• Rest and serve: Let the lasagna rest 10–15 minutes before slicing. This helps it set and hold together. Garnish with fresh basil or parsley.

How to Make It

1. Prep the zucchini “noodles”: Preheat the oven to 400°F (200°C).

   Slice zucchini lengthwise into 1/8–1/4-inch thick planks using a knife or mandoline. Lay them on paper towels, sprinkle lightly with salt, and let sit 15 minutes to draw out moisture.

2. Roast the slices: Pat the zucchini dry, brush lightly with olive oil, and arrange on two lined baking sheets. Roast for 10–12 minutes, flipping halfway, until pliable and lightly golden.

   This step prevents watery lasagna.

3. Make the meat sauce: Heat a tablespoon of olive oil in a large skillet over medium heat. Sauté onion until translucent, about 3–4 minutes. Add garlic and cook 30 seconds.

   Add ground meat, breaking it up as it browns. Season with salt, pepper, Italian seasoning, and red pepper flakes if using.

4. Finish the sauce: Stir in tomato paste and cook 1 minute. Add marinara, reduce heat, and simmer 8–10 minutes until slightly thickened.

   Taste and adjust seasoning.

5. Mix the ricotta layer: In a bowl, combine ricotta, egg, half the Parmesan, a pinch of salt and pepper, and a tablespoon of chopped basil or parsley. Stir until smooth.
6. Assemble the lasagna: Lower oven to 375°F (190°C). In a 9×13-inch baking dish, spread a thin layer of meat sauce.

   Add a single layer of zucchini slices, slightly overlapping. Dollop and spread a third of the ricotta mixture, sprinkle with mozzarella, then add sauce. Repeat layers—zucchini, ricotta, mozzarella, sauce—until you run out, finishing with sauce and the remaining mozzarella and Parmesan.

7. Bake: Cover loosely with foil (tented so it doesn’t touch the cheese) and bake 20 minutes.

   Uncover and bake another 10–15 minutes, until bubbly and golden on top.

8. Rest and serve: Let the lasagna rest 10–15 minutes before slicing. This helps it set and hold together. Garnish with fresh basil or parsley.

Storage Instructions

• Refrigerator: Cool completely, then cover or store in airtight containers for up to 4 days.
• Freezer: Freeze individual portions tightly wrapped for up to 2 months.

  Thaw overnight in the fridge for best texture.

• Reheating: Reheat in a 350°F (175°C) oven for 15–20 minutes or microwave in short bursts. Add a splash of water and cover to keep it moist.

Benefits of This Recipe

• Lower carbs, same satisfaction: Zucchini replaces pasta without sacrificing flavor or comfort.
• Protein-packed: Meat, ricotta, and mozzarella keep you full and energized.
• Veggie-forward: A great way to use garden zucchini and boost daily greens.
• Meal prep friendly: Holds up well in the fridge and freezes nicely.
• Gluten-free by design: No noodles means no gluten, as long as your sauce is certified gluten-free.

What Not to Do

• Don’t skip salting and roasting the zucchini: This is key to preventing a watery casserole.
• Don’t drown it in sauce: Too much liquid will make it soupy. Use just enough to coat each layer.
• Don’t cut it too soon: Slicing immediately after baking leads to collapsing layers.

  Rest time matters.

• Don’t over-slice the zucchini: Ultra-thin strips tear easily; too thick, and they won’t soften properly. Aim for 1/8–1/4 inch.
• Don’t forget to taste as you go: Season each component so the final dish is well-balanced.

Recipe Variations

• Vegetarian version: Swap the meat for sautéed mushrooms and spinach, or use a plant-based ground.
• White lasagna: Use a garlicky Alfredo-style sauce and add shredded chicken and spinach for a creamy twist.
• All-beef or sausage: Go richer with Italian sausage or a beef-and-pork blend. Drain excess fat to keep it from getting greasy.
• Spicy arrabbiata: Use a spicy tomato sauce, add crushed red pepper, and finish with fresh chili slices on top.
• Extra veg: Layer in roasted red peppers, sautéed kale, or caramelized onions for more depth.
• Dairy tweaks: Try part-skim ricotta, add cottage cheese for extra protein, or finish with provolone instead of mozzarella.

FAQ

How do I keep zucchini lasagna from getting watery?

Pat the slices dry after salting, roast them before layering, and avoid overloading the dish with sauce.

Let the lasagna rest before slicing, which helps it set.

Can I make this ahead?

Yes. Assemble up to a day in advance, cover, and refrigerate. Add 5–10 minutes to the baking time since it will be cold going into the oven.

What’s the best way to slice zucchini?

A mandoline gives consistent slices, but a sharp chef’s knife works fine.

Aim for uniform thickness so the layers cook evenly.

Is this recipe keto-friendly?

It can be. Choose a low-sugar marinara and watch portions of onions and tomatoes. The rest of the ingredients fit into many low-carb plans.

Can I use eggplant instead of zucchini?

Absolutely.

Slice, salt, and roast eggplant the same way. It offers a heartier texture and pairs well with both tomato and white sauces.

What if I don’t eat meat?

Use mushrooms, spinach, or a plant-based ground. Make sure to cook off extra moisture so the lasagna stays firm.

How do I know it’s done?

The edges should bubble and the top should be golden.

A thermometer inserted in the center should read at least 165°F (74°C).
