Ina Garten’s roasted vegetable lasagna is a flavorful, meatless lasagna made with layers of oven-roasted vegetables like zucchini, bell peppers, and mushrooms, combined with ricotta cheese, mozzarella, Parmesan, and a homemade tomato sauce. It’s baked until bubbly and golden on top, delivering a well-balanced dish that’s as nourishing as it is comforting.
2 zucchini, sliced lengthwise
2 red bell peppers, cut into strips
1 yellow bell pepper, cut into strips
1 large red onion, sliced
8 oz mushrooms, sliced
3 tablespoons olive oil
Salt and black pepper, to taste
1 teaspoon dried oregano
1 box lasagna noodles (regular or no-boil)
4 cups marinara sauce (homemade or store-bought)
15 oz ricotta cheese
2 eggs
2 cups shredded mozzarella cheese
¾ cup grated Parmesan cheese
¼ cup fresh basil, chopped (optional for garnish)
Preheat the oven to 425°F (220°C). Place zucchini, peppers, onion, and mushrooms on a sheet pan. Drizzle with olive oil, sprinkle with salt, pepper, and oregano. Toss well. Roast for 20–25 minutes until vegetables are tender and lightly browned.
In a mixing bowl, combine ricotta cheese, eggs, a pinch of salt, and ¼ cup Parmesan. Mix well until smooth and creamy.
If using regular lasagna noodles, cook according to package directions. Drain and set aside on a lightly oiled surface to prevent sticking.
Spread a thin layer of marinara sauce on the bottom of a 9×13-inch baking dish. Add a layer of noodles, then half the roasted vegetables. Spread one-third of the ricotta mixture, sprinkle some mozzarella, and add sauce. Repeat layers. Finish with noodles, sauce, mozzarella, and remaining Parmesan.
Cover the dish with foil and bake at 375°F (190°C) for 30 minutes. Remove foil and bake for another 15–20 minutes until the top is golden and bubbling.
Allow the lasagna to sit for 10–15 minutes before slicing. This helps the layers set and makes serving easier.
