Ingredients

  • 12 lasagna noodles (regular or no-boil)
  • 2 tablespoons olive oil
  • 1 medium onion, finely chopped
  • 3 cloves garlic, minced
  • 1 cup mushrooms, sliced
  • 1 medium zucchini, diced
  • 1 red bell pepper, diced
  • 4 cups fresh spinach, roughly chopped
  • 1 (28 oz) can crushed tomatoes
  • 2 tablespoons tomato paste
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • Salt and pepper to taste
  • 15 oz ricotta cheese
  • 1 large egg
  • 2 cups shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • Fresh basil leaves for garnish (optional)

Equipment

  • Large pot for boiling noodles
  • Large skillet or sauté pan
  • Mixing bowls
  • 9×13 inch baking dish
  • Wooden spoon or spatula
  • Measuring cups and spoons
  • Aluminum foil

Instructions

  1. Prepare the noodles: Bring a large pot of salted water to a boil. Add the lasagna noodles and cook according to package instructions until al dente. Drain and rinse with cold water to prevent sticking. Set aside.
  2. Make the vegetable sauce: Heat olive oil in a large skillet over medium heat. Add chopped onion and sauté for 3-4 minutes until translucent. Stir in garlic and cook for another 30 seconds until fragrant.
  3. Add mushrooms, zucchini, and red bell pepper: Cook for 5-7 minutes until vegetables are tender. Stir in chopped spinach and cook until wilted, about 2 minutes.
  4. Simmer the tomato sauce: Pour in crushed tomatoes and tomato paste. Add dried oregano, basil, salt, and pepper. Stir well and reduce heat to low. Let sauce simmer gently for 15-20 minutes, stirring occasionally.
  5. Prepare the ricotta mixture: In a bowl, combine ricotta cheese and egg. Mix thoroughly until smooth. Season lightly with salt and pepper.
  6. Preheat oven to 375°F (190°C).
  7. Assemble the lasagna: Spread a thin layer of vegetable tomato sauce on the bottom of your baking dish. Layer 4 cooked noodles evenly on top.
  8. Add ricotta layer: Spoon and spread one-third of the ricotta mixture over the noodles.
  9. Add sauce and cheese: Spread one-third of the vegetable sauce over the ricotta, then sprinkle with 1/3 of the mozzarella.
  10. Repeat layers: Repeat steps 7-9 two more times, finishing with mozzarella and Parmesan cheese on top.
  11. Bake covered: Cover the baking dish tightly with aluminum foil. Bake for 25 minutes.
  12. Uncover and bake: Remove foil and bake for an additional 15-20 minutes, or until cheese is bubbly and golden brown.
  13. Rest before serving: Let the lasagna cool for at least 10 minutes to set. Garnish with fresh basil leaves if desired.

Tips & Variations

“For an even heartier lasagna, try adding sautéed eggplant or roasted butternut squash to your vegetable mix.”

You can customize this lasagna based on your favorite vegetables or seasonal produce. For a vegan version, substitute ricotta with tofu-based ricotta and use vegan mozzarella alternatives.

If you prefer extra cheesy layers, add a bit more mozzarella or sprinkle in some shredded fontina cheese. Using no-boil noodles can save you time, but make sure your sauce is sufficiently moist to avoid dryness.

For a spicy kick, sprinkle red pepper flakes into the sauce or layer in some sliced roasted red peppers.
