  • 1 large onion, chopped
  • 1 tablespoon olive oil
  • 6 garlic cloves, minced
  • 1 can (28 ounces) tomato puree
  • 1 can (8 ounces) tomato sauce
  • 3 tablespoons minced fresh basil
  • 3 tablespoons minced fresh oregano
  • 1 teaspoon sugar
  • 1/2 teaspoon crushed red pepper flakes
  • 4 cups sliced zucchini
  • 3 cups sliced fresh mushrooms
  • 2 medium green peppers, cut into 1-inch pieces
  • 1 medium onion, cut into 1-inch pieces
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 6 lasagna noodles, cooked, rinsed and drained
  • 4 cups shredded part-skim mozzarella cheese
  • 1 cup shredded Parmesan cheese


  1. Preheat oven to 450°. In a large saucepan, saute onion in oil until tender over medium heat; add garlic and cook 1 minute longer. Stir in the tomato puree, sauce and seasonings. Bring to a boil. Reduce heat; simmer, uncovered, until slightly thickened, 20-25 minutes.
  2. Meanwhile, in a large bowl, combine the vegetables, salt and pepper. Transfer to two 15x10x1-in. baking pans coated with cooking spray. Bake until golden brown, 15-18 minutes. Reduce oven temperature to 400°.
  3. Spread 1/2 cup of the sauce into a 13x9-in. baking dish coated with cooking spray. Layer with three noodles, 1-3/4 cups sauce, and half of the roasted vegetables and cheeses. Repeat layers.
  4. Cover and bake for 10 minutes. Uncover; bake until bubbly and golden brown, 10-15 minutes longer. Let stand for 10 minutes before serving. If desired, garnish with additional fresh oregano.

You can also substitute no-boil noodles for boiled lasagna noodles if you like—just make sure to cover the noodles completely with sauce so they have enough liquid to cook.

Can you make this easy vegetable lasagna ahead of time?
