Ingredients

Gathering your ingredients is the first step to creating this incredible vegetarian lasagna. We focus on fresh, high-quality components to ensure the best flavor.

For the Roasted Vegetables

Extra-virgin olive oil: Essential for coating vegetables and promoting browning.
8 ounces cremini mushrooms: Stemmed and quartered, these add a rich, earthy flavor.
1 red bell pepper: Stemmed, seeded, and cut into 1-inch pieces for sweetness and color.
1 medium zucchini: Cut into ½-inch pieces, offering a tender texture.
½ medium yellow onion: Cut into ½-inch pieces for a foundational aromatic taste.
Sea salt: To season the vegetables perfectly.
Freshly ground black pepper: Adds a subtle spice and aroma.

For the Lasagna Layers

15 lasagna noodles: Regular oven-ready or traditional noodles work well; ensure they are cooked al dente.
3 cups marinara sauce: A quality store-bought brand saves time, or use your favorite homemade recipe.
3 cups fresh spinach: Adds a layer of freshness and nutrients that wilts beautifully.
2 cups grated low-moisture, part-skim mozzarella cheese: For that classic gooey, cheesy pull.
½ cup grated pecorino cheese: Contributes a sharp, salty depth of flavor.

For the Ricotta Filling

3 cups whole milk ricotta cheese: The creamy heart of the lasagna, providing richness.
3 garlic cloves: Grated for an even distribution of pungent flavor.
2 teaspoons lemon zest: Brightens the ricotta mixture with a fresh, citrusy note.
1 teaspoon sea salt: Enhances all the flavors in the filling.
Freshly ground black pepper: For a touch of warmth and spice.

For Garnish

Fresh basil leaves or chopped fresh parsley: Adds a vibrant finish and aromatic touch.

Notes & Substitutions

When making your vegetarian lasagna, a few tweaks can customize it perfectly. For noodles, regular lasagna noodles yield the best texture, but you can use no-boil noodles if you prefer a quicker prep. For cheeses, feel free to experiment; provolone or fontina can be excellent additions to the mozzarella and pecorino. Consider adding other vegetables like eggplant, finely chopped carrots, or sun-dried tomatoes to your roasted mix for extra flavor and nutrition. If you want a deeper flavor in your marinara, consider a San Marzano tomato-based sauce. For a completely vegan vegetarian lasagna, simply substitute the ricotta with a plant-based alternative and use a dairy-free mozzarella.

Equipment

Having the right tools ready makes preparing this delicious vegetarian lasagna a breeze. You likely have most of these items already in your kitchen.

9×13-inch baking dish: The standard size for assembling and baking your lasagna.
Large baking sheet: Essential for roasting your medley of fresh vegetables evenly.
Large pot for noodles: Needed to boil the lasagna noodles to perfect al dente tenderness.
Large mixing bowl: For combining the creamy ricotta cheese filling ingredients.
Grater: Ideal for finely grating garlic cloves and lemon zest into the ricotta.

Instructions

Creating this flavorful vegetarian lasagna is a straightforward process when you follow these simple steps. Each layer builds on the last to create a truly irresistible dish.

Preheat oven to 425°F, prepare a baking sheet with parchment, and oil a 9×13-inch baking dish.
Toss mushrooms, bell pepper, zucchini, and onion with olive oil, salt, and pepper on the baking sheet. Roast for 20-25 minutes until tender and browned, then reduce oven to 400°F.
While vegetables roast, cook lasagna noodles in salted boiling water until al dente, then drain and toss with olive oil.
In a large bowl, combine ricotta, grated garlic, lemon zest, salt, and black pepper for the filling.
Assemble by spreading 1 cup marinara in the dish, then layer with noodles, half the ricotta, half the spinach, half the roasted vegetables, and ⅔ cup marinara sauce.
Repeat the layers with noodles, remaining ricotta, spinach, vegetables, and another ⅔ cup sauce, finishing with the last layer of noodles.
Spread the final ⅔ cup marinara over the top, sprinkle with mozzarella and pecorino, then bake for 30 minutes until bubbly and browned. Let stand 20 minutes before garnishing and serving.

Pro Tips & Troubleshooting

Making a perfect vegetarian lasagna is easier with a few expert tips. These insights help you avoid common pitfalls and ensure a consistently delicious result.

Perfectly Cooked Noodles: Always cook your lasagna noodles al dente. Overcooked noodles can become mushy, leading to a less structured lasagna. A drizzle of olive oil after draining prevents sticking.
Proper Vegetable Roasting: Don’t overcrowd your baking sheet when roasting vegetables. Giving them space ensures they caramelize and become tender, not steamed and watery.
Prevent Watery Lasagna: Excess moisture is the enemy. Ensure your spinach is dry, and don’t skip roasting the vegetables to remove some of their water content. A good quality, thicker marinara sauce also helps.
Golden-Brown Top: For that irresistible bubbly, golden-brown cheese crust, consider a quick broil for the last minute or two of baking. Keep a close eye on it to prevent burning.
Optimal Resting Time: Resting the lasagna for at least 20 minutes after baking allows the layers to firm up and the cheese to set. This makes for cleaner slices and a better overall presentation.

Serving, Storage & Variations

Once your delicious vegetarian lasagna is ready, knowing how to serve and store it properly ensures maximum enjoyment. Plus, there are many ways to make it your own!

Serving Suggestions

Serve this hearty vegetarian lasagna with simple yet complementary sides.

A light green salad with a vinaigrette dressing provides a refreshing contrast.
Crusty garlic bread is perfect for soaking up any extra sauce.
Consider other Italian-inspired sides like steamed green beans or roasted asparagus.

Storage Instructions

Store any leftover lasagna in an airtight container in the refrigerator for up to 3-4 days. This keeps it fresh and delicious.
To reheat individual servings, simply microwave until warmed through, or heat in a preheated oven at 350°F (175°C) until bubbly.

Freezing Instructions

For make-ahead convenience, you can freeze this vegetarian lasagna before baking. Assemble it completely, then cover it tightly with plastic wrap and aluminum foil. Freeze for up to 3 months.
To bake from frozen, remove foil and plastic, cover with new foil, and bake at 375°F (190°C) for 1 hour, then uncover and bake for another 30-45 minutes, or until bubbly and heated through.

Variations

Vegan Lasagna: Easily make this recipe plant-based by using a high-quality vegan ricotta cheese and your favorite dairy-free mozzarella shreds. Ensure your marinara sauce is also vegan.
Gluten-Free Lasagna: Simply swap out traditional pasta for gluten-free lasagna noodles. Follow the package directions carefully as cooking times can vary.
Seasonal Vegetables: Adapt the roasted vegetables to what’s in season. Try finely diced butternut squash in the fall, or tender asparagus and peas in the spring for a fresh twist.

FAQ

Can I use no-boil lasagna noodles?

Yes, you can! Just ensure your sauce is a bit thinner and you have enough moisture in the dish, as these noodles absorb more liquid during baking.

How do I prevent watery lasagna?

Roast your vegetables thoroughly to remove excess moisture. Also, ensure your spinach is dry, and use a thick marinara sauce.

Can I make this lasagna ahead of time?

Absolutely! Assemble the lasagna completely, cover it, and refrigerate it for up to 24 hours before baking.
