Caramelized roasted vegetables, creamy ricotta, and melted mozzarella layered into the ultimate comfort-food vegetarian lasagna.

# Ingredients:

For the roasted vegetables

01 - 2 medium zucchini, cut into 1-inch chunks
02 - 1 medium eggplant, cut into 1-inch chunks
03 - 2 red bell peppers, seeded and cut into thick strips
04 - 1 large yellow onion, cut into wedges
05 - 3 tablespoons olive oil
06 - 3 cloves garlic, minced
07 - Salt and black pepper

For the ricotta filling

08 - 15 oz (425 g) whole milk ricotta cheese
09 - 1 large egg
10 - 1/2 cup (50 g) grated parmesan cheese
11 - 1/4 teaspoon ground nutmeg
12 - 1/2 teaspoon salt
13 - 1/4 teaspoon black pepper
14 - 5 oz (140 g) fresh spinach, wilted and squeezed dry

For assembly

15 - 12 no-boil lasagna sheets (about 10-12 oz / 300 g)
16 - 4 cups (950 ml) marinara sauce
17 - 2 cups (200 g) shredded mozzarella cheese
18 - 1/2 cup (50 g) grated parmesan cheese

# Instructions:

01 - Preheat the oven to 425°F. Toss zucchini, eggplant, peppers, and onion with olive oil, garlic, salt and pepper. Spread on two large baking sheets in a single layer. Roast for 25-30 minutes, turning once, until browned and tender. Remove and reduce oven to 375°F.
02 - In a bowl, stir together ricotta, egg, parmesan, nutmeg, salt and pepper until well combined. Fold in the wilted spinach that has been squeezed very dry.
03 - Spread 1 cup of marinara on the bottom of a 9x13 inch baking dish. Add a layer of lasagna sheets. Top with half the roasted vegetables, half the ricotta mixture, 1/2 cup of mozzarella, and 1 cup of sauce. Repeat the layers once more. Finish with a final layer of noodles, the remaining sauce, and the remaining mozzarella and parmesan.
04 - Cover the dish tightly with foil and bake at 375°F for 30 minutes. Remove the foil and bake 15-20 minutes more until the cheese is golden and the edges are bubbling. Let the lasagna rest for at least 15 minutes before slicing and serving.

# Good to know:

01 - Let the lasagna rest at least 15 minutes before slicing so the layers hold together.
02 - The lasagna can be assembled up to 24 hours ahead and refrigerated before baking.
