Prep The Zucchini First things first—heat your oven. Preheat oven to 425–450°F (220–230°C). Hotter oven = better browning. Line a rimmed baking sheet with parchment paper, or lightly oil it. Now, slice: Wash and trim the ends off 2–3 medium zucchini. For classic rounds: slice into ¼–½-inch thick circles. For “fries”: cut lengthwise into planks, then into sticks. A quick moisture trick: Zucchini holds a lot of water. If you have time, sprinkle the slices lightly with salt, let them sit for 10–15 minutes, then pat dry with paper towels. If you don’t have time, at least pat them dry once after slicing. It helps a lot with crispness.

Season And Coat Grab a large bowl. Add the zucchini slices and: Drizzle with the olive oil. Sprinkle in garlic powder, salt, pepper, and Italian seasoning. Toss everything until each slice is lightly coated. Now add the cheese: Sprinkle most of the Parmesan into the bowl and toss again. Save a little Parmesan to sprinkle over the top once the slices are on the pan. That exposed cheese is what gets beautifully golden. If you’re using panko: Mix panko and Parmesan in a small bowl with an extra pinch of seasoning. You can either toss the zucchini in the mix or sprinkle it over the slices on the pan.

Arrange For Maximum Crisp This part sounds minor, but it makes a difference. Lay the zucchini in a single layer on the baking sheet. Don’t overlap the slices—if they pile on top of each other, they steam instead of crisp. If you cut fries, lay them with one cut side down so as much surface area as possible touches the pan. Sprinkle: Add the remaining Parmesan (and crumb mix, if using) over the top. Don’t worry if some falls onto the pan. Those little puddles of cheese turn into crispy, lacy bits you can snack on.

Bake (and broil for extra crunch) Slide the pan into the hot oven: Bake for 10–12 minutes to start. Thicker pieces or spears may need 12–15 minutes. You’re looking for: Cheese that’s melted and starting to turn golden. Zucchini that’s tender when you poke it with a fork but still holds its shape. If you love a really crispy top: Switch to broil for the last 2–3 minutes. Keep the pan on the upper-middle rack and watch closely. Cheese goes from perfect to burnt very fast.

Serve It Hot And Happy Once it’s done: Let the zucchini rest on the pan for 2–3 minutes so the cheese sets. Use a spatula to lift the slices, scraping up any extra crispy cheese from the pan. Those “cheese chips” are gold. Finish with: A sprinkle of fresh parsley or basil, if you have it. A squeeze of lemon adds brightness if the dish tastes rich. Serve right away with your favorite dip—ranch, marinara, garlic yogurt, even a spicy mayo. It disappears faster than you’d expect, especially if you eat one straight from the pan “just to test it.”
