Garlic Parmesan Roasted Zucchini Recipe Ingredients

• 3 medium zucchini, about 1½ pounds total
• 2 tablespoons olive oil
• 3 garlic cloves, finely minced
• ½ cup finely grated Parmesan cheese
• ¼ cup plain breadcrumbs
• 1 teaspoon Italian seasoning
• ½ teaspoon salt
• ¼ teaspoon ground black pepper
• ¼ teaspoon garlic powder
• 2 tablespoons chopped fresh parsley
• 1 teaspoon fresh lemon juice, optional

How to Make Garlic Parmesan Roasted Zucchini

1. Preheat the oven.
   Set the oven to 425°F. Line a large rimmed baking sheet with parchment paper or lightly coat it with cooking spray.A hot oven helps the zucchini brown quickly instead of slowly releasing water and becoming soft.
2. Cut the zucchini.
   Wash and dry the zucchini. Trim off the ends, then cut the zucchini into rounds about ½ inch thick.Try to keep the slices close to the same thickness so they finish roasting at the same time. Slices that are too thin may become limp or burn around the edges.
3. Dry the slices.
   Spread the zucchini rounds over a clean kitchen towel or several layers of paper towels. Pat the tops dry.Removing surface moisture gives the olive oil and Parmesan mixture a better chance to stick.
4. Season the zucchini.
   Place the zucchini slices in a large bowl. Add the olive oil and minced garlic, then toss until every piece is lightly coated.
5. Make the Parmesan coating.
   In a small bowl, combine the grated Parmesan, breadcrumbs, Italian seasoning, salt, black pepper, and garlic powder.Sprinkle the mixture over the zucchini. Toss gently until the slices are coated on both sides.
6. Arrange the zucchini.
   Place the seasoned zucchini rounds in a single layer on the prepared baking sheet. Leave a little room between the pieces.Do not stack or crowd them. When the slices overlap, they trap steam and cook unevenly.
7. Roast until tender.
   Bake for 12 to 15 minutes, or until the zucchini is tender and the Parmesan coating has started to turn golden.The exact cooking time will depend on the thickness of the slices. Check them after 12 minutes so they do not overcook.
8. Broil for extra browning.
   For a deeper golden finish, switch the oven to broil and cook the zucchini for 1 to 2 minutes.Watch carefully during this step. Parmesan can change from browned to burned quickly under the broiler.
9. Finish and serve.
   Remove the baking sheet from the oven and sprinkle the zucchini with chopped parsley. Add a small squeeze of lemon juice for brightness, if desired.Serve immediately while the coating is warm and lightly crisp.

Recipe Notes and Tips

Do not slice the zucchini too thin

Rounds that are about ½ inch thick hold their shape better in the oven. Very thin slices release moisture quickly and may become soft before the Parmesan has time to brown.

Use freshly grated Parmesan

Fresh Parmesan melts and browns more evenly than the dry cheese sold in shelf-stable containers. Finely grate it so it spreads easily over the zucchini.

Avoid overcrowding the baking sheet

The zucchini should sit in one layer with a little space between the rounds. Use two baking sheets when necessary rather than forcing everything onto one crowded pan.

Make it without breadcrumbs

The breadcrumbs help create a slightly crisp coating, but they are not essential. Replace them with additional Parmesan for a low-carb version.

Add a little heat

Mix ¼ teaspoon of crushed red pepper flakes into the Parmesan coating. That small amount adds warmth without overpowering the garlic and cheese.

Storage

Refrigerate leftover roasted zucchini in an airtight container for up to three days. The coating will soften as it sits, but the flavor will remain good.

Reheat the zucchini on a baking sheet at 400°F for 5 to 8 minutes. An air fryer also works well and helps restore some of the crisp texture.

Make-ahead option

The Parmesan and breadcrumb mixture can be combined up to one week in advance and stored in a sealed container. Cut and season the zucchini shortly before roasting for the best texture.

Frequently Asked Questions

How do you keep roasted zucchini from getting soggy?

Use a hot oven, dry the zucchini before seasoning, and arrange the pieces in a single layer. Crowding the pan traps moisture and causes the zucchini to steam instead of roast.

It also helps to avoid salting the zucchini too far in advance. Salt draws out water, so season the slices just before they go into the oven.

Can I make Garlic Parmesan Roasted Zucchini in an air fryer?

Yes. Arrange the seasoned zucchini in a single layer in the air-fryer basket and cook at 400°F for 8 to 10 minutes. Turn or shake the basket halfway through cooking.

You may need to cook it in batches so the slices are not crowded.

Can I use yellow squash instead of zucchini?

Yellow summer squash is a good substitute and can be prepared the same way. You can also use half zucchini and half yellow squash for a colorful side dish.

Choose firm squash without soft spots. Larger squash may contain more water and seeds, so medium-sized vegetables usually produce the best texture.

What should I serve with roasted zucchini?

Garlic Parmesan zucchini pairs well with baked chicken, grilled steak, salmon, meatballs, or roasted turkey. It is also a simple vegetable side for pasta, rice dishes, casseroles, and sandwiches.

An Easy Side Worth Repeating

This is the kind of vegetable dish that disappears while it is still warm from the oven. The salty Parmesan, toasted garlic, and browned edges make these zucchini rounds easy to serve on an ordinary weeknight, yet good enough to place beside a larger Sunday dinner.
