1mediumzucchinicut into 1-inch cubes
1red onionthinly sliced
Salt and freshly ground black pepper
3tablespoons(45ml)extra-virgin olive oil
2cupsbaby spinach leavesor other leafy greens
1pound(450g)whole milk ricotta
¾cupgrated fresh Parmesan cheese
2tablespoonschopped parsleyor fresh basil, plus more for garnish
½pound(225g)fontina, low-moisture mozzarella or havarti cheesecoarsely grated or shredded Chef tip: to easily grate a chunk of soft-textured cheese, put it in the freezer for about 20 minutes.
Heat oven to 425 ( 220C) degrees, with the rack positioned in the center.
Make the sauce:
Put the tomatoes on a large rimmed baking sheet with the garlic, olive oil and 1 teaspoon salt. Roast until the tomatoes are very soft, about 20-25 minutes.
Transfer the tomatoes and all the pan juices to a blender or food processor and blend until smooth. The sauce can be made up to one week ahead and stored in the refrigerator.
Roast the vegetables
Toss the eggplant, bell peppers, zucchini, and red onion on a rimmed baking sheet. Add 1 ½ teaspoons salt, black pepper and the olive oil and toss everything to coat.
Roast the vegetables alongside the tomatoes 20-25 minutes, stirring halfway through, until they're are soft and slightly browned. Remove from the oven and immediately add the spinach. Toss with tongs to mix and wilt the greens.
Assemble and bake the lasagna
Reduce the oven temperature to 400 (200C) degrees.
Lightly coat an 8x8-inch baking pan with olive oil.
Combine the ricotta, ¼ cup of Parmesan and the parsley in a small bowl.
Ladle ⅓-cup tomato sauce evenly over the bottom of the pan. Arrange 3 pasta sheets, slightly overlapping, over the sauce. Spread ⅓ of the vegetables, ⅓ of the ricotta mixture, ⅓ of the grated fontina and ⅓ cup sauce over the noodles. Repeat twice more, gently pressing the noodles down each time. Make the final top layer with all the remaining sauce and ½ cup of the Parmesan cheese.
Cover the pan with foil and place on a baking sheet to avoid spills in the oven. Bake 30 minutes. Take a peek under the foil — if the sauce is bubbling, the cheese melted and the noodles are tender, it's done. If not, cover and bake an additional 5 to 10 minutes.
Remove the pan from the oven and cool 30-60 minutes before serving. Sprinkle with chopped parsley. Slice into pieces and serve.

Notes
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.
Make the fresh cherry tomato sauce as directed in the recipe, or feel free to use your favorite sauce instead. You'll need one quart of sauce (about 2 cups) to layer with the noodles.
If you want to double this lasagna recipe for a larger crowd, a rectangular baking panor glass/ceramic dish that's 13 x 9 inches will work. The baking time will be the same.
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!
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 of bite-size vegetables that are roasted or cooked until tender. Try mushrooms, leeks, butternut squash, kale, or other greens.
To freeze an un-baked lasagna:
Assemble the lasagna in the pan according to the steps.
Wrap the pan securely with heavy-duty aluminum foil.
Label and date the lasagna and freeze for 1-2 months.
Defrost overnight in the refrigerator. Bake as directed in the recipe.
If you're freezing and defrosting a baked lasagna, first cool the lasagna completely — this helps prevent freezer burn from condensation. To reheat, place in a 350 degrees (covered) for about 15 minutes, until it's heated through.
