Creating Vegetarian Lasagna is a delightful journey. Follow these easy steps to make this incredible dish:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Cook Noodles: In a large pot, boil water and cook the lasagna noodles according to the package instructions. Drain and set aside.
3. Sauté Vegetables: In a large skillet, heat olive oil over medium heat. Add the onion and garlic, cooking until softened (about 3-4 minutes).
4. Add More Veggies: Stir in the bell pepper, zucchini, spinach, and mushrooms. Cook until vegetables are tender, about 5-7 minutes. Season with Italian seasoning, salt, and black pepper.
5. Prepare Cheese Mixture: In a separate bowl, combine the ricotta cheese and egg. Mix well until combined.
6. Layer the Lasagna: In a 9×13 inch baking dish, spread a thin layer of marinara sauce at the bottom. Lay three lasagna noodles over the sauce.
7. First Layer: Spread half of the ricotta mixture over the noodles, then add half of the vegetable mixture, followed by one-third of the mozzarella cheese.
8. Repeat: Repeat the layering process by adding more marinara, noodles, ricotta, vegetables, and mozzarella until you complete the layers. Top the final layer with remaining marinara sauce and sprinkle with Parmesan and the rest of the mozzarella cheese.
9. Cover with Foil: Cover the baking dish with aluminum foil (make sure it doesn’t touch the cheese to avoid sticking).
10. Bake: Place the lasagna in the oven and bake for 25-30 minutes. Remove the foil and bake for an additional 20 minutes or until the cheese is bubbly and golden brown.
11. Rest: Remove the lasagna from the oven and let it rest for 10 minutes before slicing.
12. Garnish: Top with fresh basil before serving, if desired.
