A family favorite: Fresh, healthy lasagna loaded with colorful roasted vegetables and three different cheeses.
Roasted vegetable lasagna was one of my most requested recipes when I was a personal chef. Some of my clients were long-term regulars, and each time I cooked for them I’d take care to change their menus.
I wanted to offer families variety 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.
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 roasted vegetable lasagna was a recipe I made on repeat for one of my vegetarian clients, and now I can say that I know why she liked it so much — it’s beautifully loaded with colorful vegetables, satisfying and comforting all at once.
Tips for making 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.
- 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.

Roasted Vegetable Lasagna full of colorful vegetables and fresh tomato sauce - a healthy family favorite!
The vegetables can be roasted the day before making the lasagna to save time. Or assemble the whole lasagna, cover and refrigerate up to a day ahead before baking.
You can use your favorite tomato sauce instead of making the roasted cherry tomato sauce. You'll need 4 cups sauce (1 quart).
Roasted Cherry Tomato Sauce:
- 2 pounds cherry tomatoes
- 2 whole garlic cloves, peeled
- 2 tablespoons extra-virgin olive oil
- 1 medium eggplant (peeled if desired), diced
- 2 bell peppers red, orange or yellow; diced
- 2 small zucchini (less than 6-inches long), diced
- 1 red onion, thinly sliced
- Salt and freshly ground black pepper
- Extra-virgin olive oil
- 2 cups baby spinach
- 1 pound whole milk ricotta
- 1/2 pound fontina cheese, coarsely grated
- 12 sheets no-boil lasagna noodles
- 1/2 cup grated fresh Parmesan cheese, plus additional for serving
To make the sauce:
- Heat oven to 425 degrees. Toss the tomatoes on a large rimmed baking sheet with the garlic, oil and 1 teaspoon salt. Roast until the tomatoes are very soft and slightly browned, about 25 minutes.
- Cool the tomatoes 10 minutes then scrape into a blender or food processor and blend until smooth.
To make the lasagna:
- Put the eggplant, bell peppers, zucchini, and red onion in a large bowl. Add 1 1/2 teaspoons salt, ground pepper to taste and 1/4 cup olive oil and toss to coat. Transfer to a large rimmed baking sheet and roast until the vegetables are soft and slightly browned, about 25 minutes. Remove from the oven and immediately add the spinach. Toss with tongs to mix together and wilt the greens.
- Reduce oven temperature to 400 degrees.
- Lightly coat an 8 x 8-inch baking pan with olive oil. Ladle 1/4-cup tomato sauce evenly over the bottom of the pan.
- Make three layers in the pan as follows: 3 pasta sheets, slightly overlapping, topped evenly with 1/3 of the vegetables, ricotta, fontina and 1/4 cup sauce. Finish the final top layer with the remaining sauce and the Parmesan cheese.
- Cover the pan with foil and bake 35 minutes. Take a peek under the foil - if the sauce is bubbling, the cheese melted and the noodles tender, it's done. If not, cover and bake an additional 5 to 10 minutes. Remove the pan from the oven and let cool for about an hour before serving. Sprinkle with additional Parmesan cheese.
