Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
2 pounds zucchini, about 3 to 4 medium zucchini
1 tablespoon olive oil, plus more for drizzling the sheet pan
1 teaspoon kosher salt
1/2 teaspoon dried Italian seasoning
1/4 teaspoon garlic powder
1/4 teaspoon black pepper
1/4 teaspoon red chili flakes, optional
2 tablespoons grated Parmesan cheese, plus more for sprinkling before serving
1 tablespoon chopped parsley
Directions
Preheat your oven to 400°F (204°C) and place the oven rack in the center position.
Lightly drizzle a large sheet pan with olive oil. You can also line the pan with foil first for easier cleanup, then lightly oil the surface.
Slice the zucchini on a slight angle into 1/2-inch thick pieces, aiming for slices about 2 to 3 inches long. Cutting them this way gives you larger pieces that roast nicely and hold their texture well.
In a large bowl, combine the zucchini slices with the olive oil, kosher salt, dried Italian seasoning, garlic powder, black pepper, and red chili flakes if using. Toss well so the zucchini is evenly coated.
Place the prepared sheet pan in the oven for 2 to 3 minutes to preheat. This helps the zucchini start browning as soon as it hits the pan.
Carefully remove the hot pan from the oven and arrange the zucchini in a single layer. Try not to overcrowd the pan, since space helps the slices roast instead of steam.
Roast for 5 to 7 minutes, or until the zucchini is just tender when pierced with a fork.
Sprinkle the grated Parmesan over the zucchini, then switch the oven to broil. Broil in the center of the oven for 2 to 4 minutes, watching closely, until the cheese is melted and lightly golden.
Remove from the oven, garnish with chopped parsley, and add a little extra Parmesan if desired. Serve warm.

Variations
You can easily change this recipe to fit your taste or what you have in the kitchen. Swap the Italian seasoning for dried oregano, basil, or thyme for a slightly different herb profile. Add lemon zest after roasting for a brighter finish.
For more texture, sprinkle on a little seasoned breadcrumb topping during the last few minutes of cooking. For a cheesier version, add a bit more Parmesan right before serving. You can also mix in yellow squash with the zucchini for a colorful variation that cooks in about the same amount of time.
If you prefer milder heat, leave out the chili flakes. If you want more spice, increase them slightly or add a pinch of cayenne.
Storage/Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days.
To reheat, place the zucchini on a baking sheet and warm it in a 375°F oven for about 5 to 8 minutes, or until heated through. This helps keep the texture better than microwaving. You can also reheat it in an air fryer for a few minutes.
The microwave works for convenience, but the zucchini will become softer. If using the microwave, heat in short intervals until just warmed through.
Freezing is not ideal for this recipe because zucchini contains a lot of water and tends to become mushy once thawed.
FAQs
Can I use smaller or larger zucchini?
Yes. Smaller zucchini are often a little sweeter and less seedy, while larger zucchini work fine as long as you cut them into evenly sized pieces.
Why is my roasted zucchini soggy?
Zucchini has high water content, so overcrowding the pan or overcooking it can make it soft and watery. Roast it in a single layer and cook just until tender.
Do I have to preheat the sheet pan?
It is not absolutely required, but it helps the zucchini start browning right away and can improve the overall texture.
Can I make this recipe without Parmesan?
Yes. The zucchini will still be flavorful from the herbs and seasonings. You can leave the cheese out or use another hard grated cheese if you prefer.
Can I prepare the zucchini ahead of time?
Yes. You can slice and season the zucchini ahead of time, then keep it refrigerated until ready to roast. For best texture, cook it shortly before serving.
What should I serve with roasted zucchini?
It goes well with grilled chicken, baked fish, pasta, rice, roasted potatoes, or other simple main dishes.
Can I use fresh garlic instead of garlic powder?
Yes. Minced fresh garlic can be used, but it may cook more quickly and can brown faster under the broiler, so keep a close eye on it.
How do I keep the zucchini from overcooking?
Cut the slices thick enough, keep the roasting time short, and watch carefully during the broiling step.
Can I make this in an air fryer?
Yes. Arrange the zucchini in a single layer and cook until tender, then add the Parmesan near the end so it melts without burning.
Is this recipe good for meal prep?
It can be, especially for a quick lunch or side dish, but it is best enjoyed fresh since zucchini softens as it sits.
