A family favorite: Fresh, healthy roasted vegetable lasagna loaded with colorful roasted vegetables and three different cheeses.

Roasted vegetable lasagna is one of my most requested vegetarian meals. This recipe makes a delicious lasagna loaded with vegetables roasted in the oven, melted and grated cheeses and a fresh cherry tomato sauce.

When I was a personal chef, I offered families a variety of dishes while trying to stick to their dietary needs – whether the menu was vegetarian, gluten-free, low-carb or keto.

But, it turns out they would often ask for the same favorite dishes over and over again, and comfort food like vegetarian lasagna was always a hit!

Ingredients for vegetable lasagna

For this lasagna, I used a mix of Mediterranean vegetables and three different cheeses.

Colorful orange, yellow and/or red bell peppers
Zucchini (green squash)
Eggplant
Sweet red onion
Leafy greens (spinach, kale or chard)
Parmesan cheese
Fontina, havarti cheese or mozzarella
Whole milk ricotta cheese
Cherry tomatoes for the sauce, or use a good prepared marinara sauce.
No-boil lasagna noodles

The chopped vegetables are tossed together on a baking sheet with olive oil and salt, then roasted for about 25 minutes.

Besides the abundance of roasted vegetables, what makes this lasagna a standout is the nice balance of pasta, cheese, vegetables and light sauce.

You can eat a serving without needing to take a nap afterward!

This vegetarian lasagna recipe was one dish I made on repeat for a vegetarian client, and I know why they liked it so much.

The baked lasagna is beautifully loaded with colorful vegetables, along with layers of cheese and sauce, that makes it taste satisfying and comforting all at once.

How to make roasted vegetable lasagna

You can make the fresh cherry tomatoes sauce as directed in the recipe, but feel free to use your favorite sauce instead. You’ll need one quart of sauce to layer with the noodles.
Mix up the variety of vegetables in the filling according to what you like and have on hand, just be sure you have about four cups total bite-size vegetables that are roasted or cooked until tender.
Other vegetables to try: mushrooms, leeks, butternut squash, kale or other greens.
Cool the lasagna for up to an hour before serving. This helps the layers to set, making it much less messy to cut and serve. But if you just can’t wait to dig right in, shorten the cooling time to 15 minutes and enjoy the gooey slices!
This recipe uses fontina instead of mozzarella. It’s a soft mild cheese that melts beautifully. If you don’t have fontina, use an equal amount of whole milk mozzarella or havarti cheese instead.

Best pan to use for making roasted vegetable lasagna

This recipe makes a square lasagna that serves about 6 – 8 people, baked in an 8 x 8-inch pan.

Depending on what’s handy, I alternate between using a few different pans when I make lasagna:

My favorite ceramic baking dish and a simple square cake pan.

If you want to double this lasagna recipe for a larger crowd, a rectangular baking pan or glass/ceramic dish that’s 13 x 9 inches will do the trick.

How to freeze vegetable lasagna

Cool the lasagna completely – this helps prevent freezer burn from condensation.
Transfer to a sturdy freezer-proof container and wrap securely with aluminum foil.
Label and date the lasagna and freeze for 1-2 months.
Defrost overnight in the refrigerator. Bake as directed.
If you’re freezing and defrosting a baked lasagna, heat at 350 degrees (covered) for about 20 minutes, until heated through.
