This fuss-free Zucchini Parmesan skips the busy breading-and-frying routine in favor of roasted zucchini strips layered with homemade tomato sauce and two kinds of cheese.
Preheat oven to 450 degrees. Prepare two rimmed baking sheets with parchment paper for easy clean-up.
In a large bowl, add zucchini strips, extra-virgin olive oil, and season with salt and freshly ground black pepper (I like ½ teaspoon salt and ¼ teaspoon pepper). Toss to combine.
Arrange zucchini slices on prepared baking sheets in a single layer. Bake until zucchini is light golden brown and fork-tender, about 12 to 15 minutes. Drain on paper towels and reduce oven temperature to 375 degrees.
To make the sauce:
Meanwhile, in a medium saucepan over medium-high heat, add 1 tablespoon olive oil and heat until shimmering. Add minced garlic and stir until fragrant, about 30 seconds. Add crushed tomatoes (be careful; they may splatter when they hit the hot oil, so keep the lid handy), basil, oregano, and red pepper flakes (if using). Bring the sauce to boil over medium-high heat.
Reduce heat to medium-low, cover, and simmer until the flavors have blended, about 10 to 15 minutes longer. Season to taste with salt and pepper (I like ½ teaspoon salt and ¼ teaspoon pepper) and keep warm over medium-low heat.
To assemble and bake the casserole:
Spread 1/4 cup tomato sauce over the bottom of a 2-quart casserole dish. Arrange one-third of the zucchini in an even layer over the tomato sauce. Spoon one-third of the remaining tomato sauce over zucchini.
Sprinkle 1/4 cup Parmesan cheese over layer, followed by 1/4 cup mozzarella. Repeat layers with remaining 2/3 zucchini slices, tomato sauce, and cheeses.
Bake until bubbling and cheese is browned and bubbling, about 30 to 35 minutes. Remove from oven and allow to rest 5 minutes before serving. Garnish with fresh parsley if desired.

Notes
Zucchini: I prefer this green-skinned variety, but if you don't love or don't have zucchini handy, follow the same instructions and swap in a similar vegetable. Voila: Yellow Squash Parmesan or Pattypan Parm.
Yield: This Zucchini Parmesan makes 4 generous slices, enough for a light main dish.
