Step‑by‑Step Instructions for Hearty Baked Italian Vegetable Lasagna
Step 1: Preheat and Prepare Noodles
Begin by preheating your oven to 375°F (190°C). While the oven warms up, cook your lasagna noodles according to the package instructions until al dente, then drain and set them aside in a small bit of olive oil to prevent sticking.
Step 2: Sauté Aromatics
In a large skillet, heat a generous drizzle of olive oil over medium heat. Add the chopped onion, cooking for about 3-4 minutes until it becomes translucent. Next, stir in the minced garlic and sauté for another minute, allowing the fragrant aromas to fill your kitchen.
Step 3: Add Vegetables
Now, toss in sliced zucchini, red and yellow bell peppers, and mushrooms into the skillet. Sauté the mixture for 5-7 minutes, stirring occasionally, until the vegetables are tender and start to brown slightly—this will deepen their flavors and give your Hearty Baked Italian Vegetable Lasagna a delightful texture.
Step 4: Incorporate Spinach and Sauce
Add the fresh spinach to the skillet, stirring until wilted, which should take about 2 minutes. Next, pour in the marinara sauce, and sprinkle the dried basil and oregano on top. Let the mixture simmer for roughly 5 minutes, ensuring all the flavors meld together beautifully.
Step 5: Prepare Cheese Mixture
In a mixing bowl, combine the ricotta cheese, egg, salt, and pepper. Stir until smooth and creamy, creating a luscious filling that will add richness to your lasagna. Set this mixture aside while you work on layering the ingredients.
Step 6: Start Layering the Lasagna
In a 9×13 inch baking dish, spread a thin layer of the vegetable sauce on the bottom to ensure the noodles don’t stick. Place 3 cooked lasagna noodles on top of this layer, laying the foundation for your Hearty Baked Italian Vegetable Lasagna.
Step 7: Add First Cheese and Sauce Layers
Spread half of the ricotta mixture evenly over the noodles, followed by half of the remaining vegetable sauce. Sprinkle 1 cup of shredded mozzarella cheese on top, creating a marvelous first layer filled with creamy goodness and vibrant vegetables.
Step 8: Repeat Layers
Repeat the layering process by adding another 3 noodles, topping with the rest of the ricotta mixture, another layer of vegetable sauce, and another cup of mozzarella cheese. This repetition builds the lasagna’s hearty character, ensuring every slice is satisfying.
Step 9: Final Assembly
Finish off your Hearty Baked Italian Vegetable Lasagna by laying down the final 3 noodles. Cover the noodles with the last of the marinara sauce and generously sprinkle the remaining mozzarella and grated parmesan cheese on top for a beautifully golden crust.
Step 10: Bake to Perfection
Cover your baking dish with aluminum foil and place it in the preheated oven. Bake for 25 minutes, then remove the foil and continue baking for an additional 15 minutes. You’ll know it’s done when the cheese is bubbly and golden brown, inviting you to dig in.
Step 11: Cool and Serve
Once baked, allow the lasagna to cool for about 10 minutes before slicing. This brief rest helps the layers set, ensuring neat servings of your delightful Hearty Baked Italian Vegetable Lasagna. Enjoy the beautiful layers and rich flavor!

You can store leftovers in an airtight container in the fridge for up to 3 days. Make sure the lasagna has cooled completely before sealing.
