How To Make Oven Roasted Zucchini
This is a summary version; for the complete list of ingredients and instructions, please refer to the recipe card below.
Toss the zucchini with olive oil. Sprinkle on the herbs. Spread them in a single layer on a parchment-covered baking sheet. Roast for about 15 minutes and then sprinkle with Parmesan and return to the oven for a couple of minutes.

Cook’s Tips
- For even more browning, sprinkle the zucchini with Parmesan and place it under the broiler on low for a couple of minutes.
- Don’t cut the zucchini too thin. Zucchini has a lot of water, so if you cut it too thin, it will turn mushy before it browns.
- The dried herbs are customizable. Use your favorite ones. You can use seasoned salt, Cajun seasoning, Creole seasoning, or Italian seasoning.

Oven Roasted Zucchini
Ingredients
- 3 medium zucchini, cut in half lengthwise and then into 1-inch chunks
- 2 tablespoons olive oil
- ½ teaspoon sea salt
- ½ teaspoon freshly ground black pepper
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon dried marjoram
- ½ teaspoon dried thyme
- ½ teaspoon crushed rosemary
- ¼ cup freshly grated Parmesan cheese
Instructions
- Preheat the oven to 425° F. Cover a large baking sheet with parchment paper. Make sure the parchment paper is rated for that high a temperature. If not, go without it.
- In a large bowl, toss the zucchini with the olive oil. Sprinkle the seasonings and herbs over the top and toss to coat. Spread the zucchini in a single layer on a parchment-covered baking sheet.
- Roast for 10 minutes. Flip and roast for 5 minutes. Sprinkle with Parmesan and return the pan to the oven under the broiler on low for 2-3 minutes. Keep a close eye on it, as broilers are unpredictable.

- Reheat in the oven at 425°F for 5-7 minutes or in a skillet over medium-high heat until warm.

I do love zucchini so this dish was ideal for me. I served it with your grilled chicken recipe but I could easily eat this with salad as a meal!
Carol
This recipe will become a staple for us. My husband loved it. He is in love with that vegetable. He’ll snack on it from the fridge! I just made steamed zukes in a red sauce for a company dinner (vegetarians).

Your oven-roasted zucchini was absolutely delicious. I loved how simple seasonings let the natural sweetness shine while the roasting created those perfectly caramelized edges. This is an easy, healthy side dish I will happily make all summer long.

This is one of my favorite dishes! I love how simple roasted zucchini is, yet it always turns out so flavorful. It’s one of those side dishes that goes with just about anything, and I find myself making it all summer long when zucchini is in season. Your recipe looks absolutely delicious, and I can’t wait to try your seasoning combination

We usually cook zucchini as a stir-fry, so oven-roasted zucchini was a nice change and so flavorful. Thanks for sharing the recipe. I can’t wait it again.
