Ingredients Needed
For a dish that serves around 6 people, you’ll need:
Vegetables
- 4 medium zucchinis (thinly sliced lengthwise; about 1/8-inch thick)
- 1 medium onion (finely chopped)
- 3 cloves garlic (minced)
- 1 red bell pepper (optional, diced for extra sweetness and color)
Cheeses
- 1 ½ cups ricotta cheese (or cottage cheese for a lighter version)
- 2 cups shredded mozzarella cheese

Sauce & Seasoning
- 3 cups marinara sauce (homemade or store-bought)

- ½ tsp red pepper flakes (optional, for a gentle kick)
- Salt and black pepper to taste
- Olive oil for sautéing
Optional Garnish
- Fresh basil leaves
- Extra Parmesan cheese
Cooking Instructions
-
Prep The Zucchini
- Wash and thinly slice zucchinis lengthwise. Lay slices on a clean towel, sprinkle lightly with salt, and let them sit for 15-20 minutes. This helps remove excess water and prevents a watery lasagna. Pat dry afterward.
-
Cook The Vegetables
- Heat a tablespoon of olive oil in a pan over medium heat. Sauté the onion and garlic until fragrant and translucent. Add diced red bell pepper if using, cook for 2-3 more minutes. Season lightly with salt and pepper.
-
Mix The Cheese Layer
- In a bowl, combine ricotta, half of the Parmesan, a pinch of salt, black pepper, and a teaspoon of dried basil. Stir until smooth and creamy.
-
Assemble The Lasagna
- Preheat the oven to 375°F (190°C).
- In a baking dish, spread a thin layer of marinara sauce.
- Layer zucchini slices over the sauce, then a layer of the ricotta mixture, followed by sautéed vegetables, a bit of mozzarella, and a spoonful of marinara.
- Repeat layers until all ingredients are used, finishing with a generous layer of mozzarella and remaining Parmesan.
-
Bake
- Cover with aluminum foil and bake for 25 minutes.
- Remove foil and bake for another 15 minutes, or until cheese is bubbly and lightly golden.
-
Rest And Serve
- Let the lasagna rest for 10 minutes before slicing. This allows layers to set and makes serving cleaner.
Ingredient Science Spotlight
Understanding the ’why’ behind each ingredient helps elevate your cooking:
- Zucchini: Contains a high water content and mild flavor. Salting helps release excess moisture, preventing a soggy lasagna.
- Ricotta: Provides creaminess and protein. Its high moisture content also blends beautifully with zucchini layers.
- Mozzarella: Melts smoothly, creating that irresistible stringy texture that makes lasagna comforting.
- Marinara Sauce: Adds acidity and sweetness that balance the creamy cheese. Tomatoes contain lycopene, a potent antioxidant that is more bioavailable when cooked.
- Herbs and spices: Basil and oregano add aromatic compounds that elevate flavor without extra calories. Red pepper flakes stimulate taste buds for a subtle kick.
Expert Tips
- Slice zucchini evenly: A mandoline slicer works wonders for consistent thickness, ensuring even cooking.
- Drain excess moisture: Salting zucchini and letting it rest reduces watery layers. You can also roast slices briefly to release water.
- Layer thoughtfully: Alternate textures-cheese, veggies, and sauce-so every bite is flavorful.
- Cover with foil first: This prevents cheese from over-browning before zucchini is tender.
Recipe Variations
- Vegan: Swap ricotta and mozzarella for cashew cream or vegan cheese alternatives.
- Low-carb: Stick strictly to zucchini layers, skipping any pasta completely.
- Extra protein: Add cooked lentils or crumbled tempeh to the vegetable layer.
- Flavor twist: Incorporate roasted mushrooms, spinach, or eggplant for additional depth.
