Step‑by‑Step Instructions for Savory Roasted Vegetable Vegetarian Lasagna
Step 1: Preheat Oven
Begin by preheating your oven to 425°F (220°C). While the oven heats up, line a baking sheet with parchment paper. This will make for easy cleanup after roasting those delicious vegetables.
Step 2: Roast Vegetables
Place the chopped cremini mushrooms, red bell pepper, zucchini, and yellow onion on the prepared baking sheet. Drizzle with extra-virgin olive oil, and sprinkle generously with sea salt and freshly ground black pepper. Roast in the preheated oven for 20-25 minutes until the vegetables are tender and slightly caramelized, then reduce the heat to 400°F (205°C).
Step 3: Cook Noodles
While your vegetables are roasting, bring a large pot of salted water to a rolling boil. Carefully add the lasagna noodles and cook according to the package instructions until al dente, typically about 8-10 minutes. Once cooked, drain the noodles and lightly drizzle with olive oil to keep them from sticking together.
Step 4: Make Ricotta Filling
In a large mixing bowl, combine the ricotta cheese, grated garlic, lemon zest, and a teaspoon of sea salt. Mix thoroughly until the ingredients are well blended and creamy. This delightful filling will add a rich layer to your savory roasted vegetable vegetarian lasagna.
Step 5: Assemble Lasagna
Grease a 9×13-inch baking dish, then spread 1 cup of marinara sauce evenly across the bottom. Layer the assembly with lasagna noodles, followed by half the ricotta mixture, fresh spinach, half of the roasted vegetables, and ⅔ cup marinara. Repeat these layers, finishing with a top layer of noodles, remaining marinara, and a mix of mozzarella and pecorino cheese.
Step 6: Bake
Once assembled, place your lasagna in the oven and bake at 400°F (205°C) for 30 minutes. Keep an eye on it as it bakes; you’ll know it’s ready when the cheese is beautifully browned and bubbling, filling your home with an irresistible aroma.
Step 7: Rest
After baking, remove the savory roasted vegetable vegetarian lasagna from the oven and let it rest for 20 minutes. This resting period allows the layers to set, making slicing and serving easier while enhancing the flavors.

How should I store leftover vegetarian lasagna?
Leftover vegetarian lasagna can be stored in an airtight container in the refrigerator for up to 4 days. Be sure to let it cool completely before sealing to keep moisture at bay! When you’re ready to enjoy it again, simply reheat in the microwave or in the oven at 350°F until warmed through.

What should I do if my lasagna turns out watery?
Very good question! If your lasagna is watery, this could be due to excess moisture from the vegetables or marinara sauce.

Can I make this dish vegan?
Yes! For a vegan version of the vegetarian lasagna, simply replace the ricotta with a homemade vegan ricotta made from blended silken tofu, lemon juice, and nutritional yeast.
