Hearty Vegetable Lasagna

This is the vegetable lasagna that converts skeptics. Roasting the zucchini, eggplant, and peppers first concentrates their flavor and prevents a watery filling, while a creamy ricotta layer and plenty of mozzarella make every bite feel indulgent.

Ingredients

  • 1 medium eggplant, cut into ½-inch cubes
  • 2 medium zucchini, sliced into rounds
  • 1 red bell pepper, diced
  • 1 yellow bell pepper, diced
  • 1 small red onion, diced
  • 4 tablespoons olive oil
  • Salt and freshly ground pepper
  • 5 cups (1.2L) good-quality marinara sauce
  • 12 lasagna noodles (regular or no-boil)
  • 30 oz (850g) whole-milk ricotta
  • 2 large eggs
  • ½ cup (50g) grated Parmesan, plus more for topping
  • ¼ cup chopped fresh basil
  • 2 tablespoons chopped fresh parsley
  • 16 oz (450g) shredded mozzarella, divided

Instructions

  1. 1

    Preheat oven to 425°F (220°C). Toss the eggplant, zucchini, peppers, and onion with olive oil, salt, and pepper. Spread on two baking sheets and roast for 25 minutes, stirring once.

  2. 2

    Reduce oven to 375°F (190°C). If using regular noodles, cook in salted water until just al dente, then drain and lay flat on a sheet pan.

  3. 3

    In a bowl, mix the ricotta, eggs, Parmesan, basil, parsley, and ½ teaspoon salt until smooth.

  4. 4

    Stir the roasted vegetables into 4 cups of the marinara sauce.

  5. 5

    Spread 1 cup of plain marinara on the bottom of a 9x13 inch baking dish. Top with 4 noodles, half the ricotta mixture, a third of the vegetable sauce, and a third of the mozzarella.

  6. 6

    Repeat: 4 noodles, remaining ricotta, another third of the sauce, another third of mozzarella.

  7. 7

    Top with final noodles, remaining vegetable sauce, the rest of the mozzarella, and a generous shower of Parmesan.

  8. 8

    Cover with foil (tented so it doesn't touch the cheese) and bake for 30 minutes.

  9. 9

    Remove foil and bake another 15-20 minutes until bubbly and deeply golden on top.

  10. 10

    Rest for at least 15 minutes before slicing. Garnish with extra basil.

Chef's Tips

  • Prep all ingredients before you start cooking for a smoother experience.
  • Taste as you go and adjust seasoning to your preference.
  • Don't overcrowd the pan—cook in batches if needed for best results.
  • Let meat rest after cooking to keep it juicy and tender.

Storage & Reheating

Store leftovers in an airtight container in the refrigerator for up to 3-4 days. To reheat, use a microwave at 50% power or warm in a covered pan over medium-low heat until heated through. For best texture, avoid reheating more than once.
