Roasted vegetables like zucchini, peppers, and mushrooms form the base of this rich vegetarian lasagna. Spinach adds some greens, while a ricotta mixture with a lemony twist makes it creamy. Melted mozzarella, pecorino, and ricotta cheese bring it all together. This one takes time to assemble but works great for special occasions or prepping ahead.

Ruffly pasta sheets tucked between oven-roasted veggies, fluffy ricotta, and hearty tomato sauce make this veggie lasagna truly special. Every mouthful combines sweet caramelized vegetables, stretchy cheese, and soft noodles that turn this familiar comfort dish into something extraordinary.

This dish started in my university years cooking for buddies, getting better with each new try. These days it's what I always make for get-togethers, and it wins over both veggie fans and meat eaters every time.

Key Components

  • Regular lasagna noodles: Don't go for no-boil options as they won't give you the right bite
  • Garden vegetables: Pick firm zucchini and mushrooms that'll stand up to roasting
  • Full-fat ricotta: Whole milk versions give you the smoothest, richest results
  • Leafy spinach: Brings vibrant color and goodness between each layer
  • Tasty marinara: Whether you make it or buy it, your sauce really counts

Cooking Method

1. Get Those Veggies Right
Start by roasting bell peppers, zucchini, onions, and mushrooms until they're golden brown. This key step packs in flavor and stops your lasagna from getting soggy.
2. Fix Up The Cheese Mix
Mix your ricotta with fresh lemon zest and garlic for bright flavors that work well with the roasted veggies. Stir it all together so the flavors spread evenly.
3. Handle The Pasta
Cook your noodles just until they have a slight bite, as they'll keep cooking in the oven. Toss them with a bit of olive oil so they won't stick together.
4. Layer Everything Carefully
Begin with sauce at the bottom, then build up with noodles, ricotta, veggies, spinach, and more sauce. Do this a few times and finish with cheese on top.
5. Bake It Just Right
Start covered if needed, then uncover to get that golden cheese top. Let it sit before cutting so your slices stay neat.

I started making lasagna during college dinner hangouts. Now years later, I've nailed the technique of building up tasty layers to create something that always brings folks together around the dinner table.

Smart Do-Ahead Options

Put everything together up to a day before and keep in the fridge. Take it out 30 minutes before cooking. Add another 10-15 minutes to your baking time if it's cold from the fridge.

Freezing Know-How

You can freeze your assembled but uncooked lasagna for up to three months. Thaw it in your fridge overnight before baking. Keep it covered with foil for the first half of cooking time.

What To Serve With It

Round out your meal with a crisp garden salad with tangy dressing, warm buttery garlic bread, or some oven-roasted broccoli or string beans.

Ways To Switch It Up

Change things based on what's in season: try yellow squash and eggplant in summer, butternut squash and kale in autumn, or go for roasted root veggies during winter months.

What started as a basic veggie main course has turned into the recipe everyone asks me for. Mixing roasted vegetables, three kinds of cheese, and well-cooked pasta creates something that feels homey yet fancy. Whether you're cooking for vegetarians or just want a filling meatless dinner, this lasagna shows how vegetables can steal the show at any meal.

Frequently Asked Questions

→ Can I prep this early?
Sure! Put it together a day in advance and keep it chilled. Add 10-15 minutes to bake if it's cold.
→ How should I heat leftover slices?
Cover them with foil and pop them in a 350°F oven until warmed, about 20-25 minutes.
→ What's the best way to freeze it?
Freeze before it's cooked. Let it thaw in the fridge overnight, then bake with an extra 15-20 minutes added.
→ Why roast the veggies first?
Roasting makes the flavors pop and reduces moisture so the dish doesn’t end up soggy.
→ Can I swap out the veggies?
Sure thing! You could roast carrots, eggplant, or butternut squash instead. Just make sure they’re soft.

03 1 medium zucchini, diced into ½-inch chunks
04 8 ounces cremini mushrooms, stems removed and quartered
05 1 red bell pepper, sliced into 1-inch pieces

→ Ricotta Filling

06 3 garlic cloves, finely grated
07 3 cups (24 ounces) ricotta, whole milk variety
08 1 teaspoon of sea salt
09 2 teaspoons grated lemon zest
10 Black pepper as needed

→ Assembly

11 2 cups shredded mozzarella cheese, part-skim
12 Extra-virgin olive oil for drizzling
13 15 sheets of lasagna noodles
14 3 cups (24 ounces) of your favorite marinara
15 Freshly chopped parsley or whole basil leaves for topping
16 ½ cup grated pecorino cheese

Instructions

Step 01

Get your oven ready by setting it to 425°F. Use parchment to cover a baking sheet and grease a 9x13 dish with olive oil.

Step 02

Spread veggies on baking sheet after tossing with oil, pepper, and salt. Roast them for 20-25 minutes till soft and browned edges form. Lower temperature to 400°F afterward.

Step 03

Boil the lasagna sheets until slightly firm (al dente). Drain, then coat lightly in olive oil so they don't stick together.

Step 04

Combine ricotta, garlic, lemon peel, salt, and a pinch of black pepper in a large mixing bowl.

Step 05

Start layering: place marinara on the bottom, then noodles, ricotta mix, spinach, and roasted veggies. Keep layering till done, topping it off with noodles, sauce, and both cheeses.

Step 06

Pop it into the 400°F oven for 30 minutes. Let the cheese get golden and bubbly. Wait 20 minutes before cutting into it.

Notes

  1. Switch to plant-based ricotta and skip cheese topping for a vegan-friendly option.
  2. If you use no-boil pasta, cooking time needs adjusting.
  3. Regular pasta sheets work best for the ideal texture.
