- Garlic – Enhances the aroma and overall flavor; always go for fresh over powdered for the best taste.
- Zucchini – Adds a tender crunch; consider eggplant as a substitute if you prefer.

Step‑by‑Step Instructions for Baked Italian Vegetable Lasagna
Step 1: Preheat and Prepare Noodles
Begin by preheating your oven to 375°F (190°C). In a large pot, cook the lasagna noodles according to the package directions until they are al dente, typically about 8–10 minutes. Once cooked, drain the noodles and lay them flat on parchment paper to prevent sticking while you prepare the filling for your Baked Italian Vegetable Lasagna.
Step 2: Sauté Aromatics
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add in the chopped onion and minced garlic, sautéing them together until the onion is translucent and fragrant, about 3–4 minutes. This aromatic base will create a flavorful foundation for the layers of vegetables that will follow in your hearty lasagna.
Step 3: Cook Vegetables
Add the chopped zucchini, red and yellow bell peppers, and sliced mushrooms to the skillet. Stir and cook the mixture until the vegetables are tender and beginning to caramelize, about 5–7 minutes. As the veggies soften, they'll release their natural flavors, enhancing the overall taste of your Baked Italian Vegetable Lasagna.
Step 4: Add Spinach and Sauce
Once the vegetables are cooked, stir in the fresh spinach until it wilts, which should take about 1–2 minutes. Then, pour in the marinara sauce along with dried basil and oregano, letting the mixture simmer for an additional 5 minutes. This allows all the flavors to meld together beautifully, creating a delicious filling for your lasagna.
Step 5: Prepare Cheese Mixture
In a separate bowl, mix together the ricotta cheese, egg, a pinch of salt, and black pepper until smooth. This creamy cheese mixture will add richness and a nice binding element to your layers, complimenting the vegetable filling in your Baked Italian Vegetable Lasagna.
Step 6: Assemble the Lasagna
In a 9x13 inch baking dish, spread a thin layer of the vegetable sauce at the bottom. Layer 3 lasagna noodles on top, followed by half of the ricotta cheese mixture, and half of the vegetable sauce mixture. Sprinkle 1 cup of mozzarella cheese over the top, creating a delectable first layer of the lasagna.
Step 7: Repeat Layers
Continue assembling layers by adding another set of 3 noodles, the remaining ricotta mixture, the rest of the vegetable sauce, and another cup of mozzarella cheese. This stacking creates the comforting layers that define your Baked Italian Vegetable Lasagna, ensuring every bite is full of flavor.
Step 8: Add Final Layers
Top your lasagna with a final set of noodles, spreading the remaining vegetable sauce evenly on top. Finish by sprinkling any remaining mozzarella cheese along with grated Parmesan cheese across the surface. These layers will achieve that perfect golden bubbly topping when baked.
Step 9: Bake to Perfection
Cover the baking dish with aluminum foil to prevent excessive browning, and place it in the preheated oven. Bake for 25 minutes, then remove the foil and continue baking uncovered for another 15 minutes. You’ll know it’s done when the cheese is deliciously golden and bubbly, inviting you to dig in.
Step 10: Let it Rest
After baking, allow your lasagna to rest for about 10 minutes before slicing. This resting period not only makes it easier to cut perfect portions but also allows the flavors to settle, resulting in lovely layers of comfort when served. Enjoy your homemade Baked Italian Vegetable Lasagna!
