Instructions

  1. Preheat and Roast Vegetables: Preheat your oven to 400°F. In a large bowl, toss the sliced zucchini, chopped red and yellow bell peppers, sliced mushrooms, and diced onion with 2 tablespoons olive oil, minced garlic, 1 teaspoon Italian seasoning, salt, and pepper. Spread the vegetables evenly on a baking sheet and roast for 15–20 minutes until tender and slightly caramelized.
  2. Prepare the Sauce: In a medium saucepan, heat 2 tablespoons olive oil over medium heat. Add the chopped onion and sauté until soft, about 5 minutes. Add the chopped garlic and cook for another minute until fragrant. Stir in the crushed tomatoes, salt, pepper, and red wine. Reduce the heat to low and let the sauce simmer gently for 15–20 minutes, stirring occasionally to blend flavors.
  3. Mix Ricotta Filling: In a large mixing bowl, combine the ricotta cheese, grated Parmesan, eggs, 1 teaspoon Italian seasoning, 1/2 teaspoon salt, and pepper. Mix thoroughly until smooth and creamy.
  4. Assemble the Lasagna: Spread 1 cup of the prepared marinara sauce on the bottom of a 9×13-inch lasagna pan. Lay down 4 lasagna noodles over the sauce. Spread one quarter of the ricotta mixture evenly over the noodles. Add one quarter of the roasted vegetables on top of the ricotta, then sprinkle one cup of shredded mozzarella over the vegetables. Add a few spoonfuls of sauce on top. Repeat these layers three more times—noodles, ricotta, roasted vegetables, mozzarella, and sauce—until all ingredients are used, topping the final layer with sauce and mozzarella cheese. You should have about 4 layers with 4 noodles each.
  5. Bake the Lasagna: Reduce oven temperature to 375°F. Place the assembled lasagna in the oven and bake for 30-40 minutes or until the cheese on top is golden brown and bubbly.
  6. Rest and Serve: Remove the lasagna from the oven and let it rest on a cooling rack for 10-15 minutes. This resting period allows the layers to set for clean slicing. Optionally, garnish with fresh basil or parsley before serving for an added fresh touch.

Notes

  • You can use no-boil lasagna noodles to save time, but make sure to adjust the layering sauce amount accordingly to keep the noodles moist.
  • Substitute grilled or sautéed vegetables if you prefer not to roast the veggies separately.
  • For a richer flavor, you can add a pinch of red pepper flakes to the sauce during simmering.
  • Leftover lasagna can be refrigerated for up to 3 days or frozen for up to 2 months.
  • Letting the lasagna rest before slicing is key to maintaining clean layers and preventing it from falling apart.
