Ingredients
  

For the lasagna
  • 12 oz Lasagna noodles Regular or no-boil.
  • 2 tbsp Olive oil
  • 3-4 cloves Garlic, minced
  • 1 small Onion, chopped
  • 1-2 Zucchini, chopped
  • 2 Bell peppers, chopped
  • 8 oz Mushrooms, sliced
  • 4 cups Spinach, packed
  • 1 tsp Salt
  • 1/2 tsp Black pepper
  • 1 tsp Dried basil
  • 1 tsp Dried oregano
  • 3-4 cups Marinara sauce About 1 cup for the bottom layer.
  • 2 cups Mozzarella cheese, shredded Shred from a block for better melting.
  • 1/2 cup Parmesan cheese, grated

Method
 

Preparation
  1. Preheat the oven to 375°F (190°C).
  2. Cook lasagna noodles according to package instructions. Drain and lay flat to prevent sticking.
  3. Heat olive oil in a large skillet over medium heat. Add minced garlic and chopped onion, sauté until translucent (about 3–4 minutes).
  4. Add chopped zucchini, bell peppers, and sliced mushrooms. Cook until softened (6–8 minutes). Stir in the spinach and cook until wilted. Season with salt, pepper, basil, and oregano.
  5. Pour a thin layer of marinara sauce into a baking dish to prevent sticking.
Assembly
  1. Layer noodles, one-third of the vegetable mixture, a layer of sauce, and shredded mozzarella. Repeat twice more, finishing with noodles and sauce on top.
  2. Sprinkle grated Parmesan cheese over the top.
Baking
  1. Cover tightly with foil and bake for 25 minutes.
  2. Remove foil and bake for another 15 minutes, or until cheese is bubbly and golden. Broil for 1–2 minutes for an extra-browned top if desired.
  3. Let the lasagna rest for 10–15 minutes before slicing.

Notes

If you'd like a creamier texture, consider adding ricotta or béchamel. Use part-skim mozzarella for a lighter option. This dish can also be assembled in advance and stored prior to baking.
