1 medium eggplant, diced into 1-inch cubes
1 red bell pepper, diced
1 yellow bell pepper, diced
1 medium onion, diced or cut into wedges
2 medium tomatoes, diced
2 tablespoons olive oil
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon garlic powder
Pasta & Sauce
9 to 12 lasagna sheets (no-boil or cooked according to package directions)
4 to 4½ cups marinara or tomato sauce
Cheese Filling
250g to 500g ricotta cheese
300g mozzarella cheese, shredded
½ to ¾ cup Parmesan cheese, grated
1 large egg
1 tablespoon fresh basil, chopped
Instructions
Roast the Vegetables
Preheat your oven to 425°F (220°C). Place zucchini, eggplant, bell peppers, onion, and tomatoes on a large baking sheet. Drizzle with olive oil and season with salt, pepper, and garlic powder. Toss well to coat evenly.
Roast for 25 to 30 minutes, stirring halfway through, until the vegetables are tender and lightly caramelized. Remove from the oven and allow them to cool slightly.
Prepare the Cheese Mixture
In a large bowl, combine ricotta cheese, egg, basil, half of the Parmesan cheese, and 1 cup of shredded mozzarella. Mix until smooth and evenly blended.
Assemble the Lasagna
Spread a thin layer of marinara sauce across the bottom of a 9×13-inch baking dish.
Arrange a layer of lasagna sheets over the sauce. Spread a portion of the ricotta mixture over the noodles, followed by a layer of roasted vegetables and a layer of sauce.
Repeat the layers until all ingredients are used. Finish with a final layer of noodles, remaining sauce, mozzarella cheese, and Parmesan cheese.
Bake
Cover the dish with foil and bake at 375°F (190°C) for 30 minutes.
Remove the foil and continue baking for 15 to 20 minutes until the cheese is melted and golden brown.
Allow the lasagna to rest for 10 to 15 minutes before slicing and serving.
Tips
Choose fresh vegetables for the best flavor and texture.
Roast vegetables thoroughly to remove excess moisture and prevent a watery lasagna.
Use a high-quality marinara sauce for richer flavor.
Allow the lasagna to rest before slicing for cleaner layers.
Freshly shred mozzarella cheese for smoother melting.
Avoid overcrowding the baking sheet when roasting vegetables.
Season each layer lightly to build flavor throughout the dish.
Ensure no-boil noodles are fully covered with sauce.
Keep the lasagna covered during the first stage of baking.
Prepare the lasagna ahead of time for easier entertaining.

Mix in olives and feta for a Mediterranean-inspired twist.
Layer cooked lentils for extra protein.
