Oven Roasted Zucchini

There are countless variations of roasted zucchini out there, but this version is my favorite. The ingredients are super simple but so flavorful, and it’s ready in less than 20 minutes – about as long as it takes to cook chicken breasts in the air fryer or bake salmon in the oven.

I love this recipe year-round, but it’s especially useful in the summer months when zucchini is in season, and everyone you know is giving it away for free. Less hands-on than sauteed zucchini, the Parmesan cheese is what really brings life to this otherwise simple vegetable.

How Long to Roast Zucchini

  • How long to roast zucchini at 400°F – approximately 10-12 minutes (plus 2 minutes broil)
  • How long to roast zucchini at 425°F – approximately 8-10 minutes (plus 2 minutes broil)
  • How long to roast zucchini at 450°F – approximately 6-8 minutes (plus 2 minutes broil)

Note: Cooking time will vary based on the type of oven used and how thick each zucchini is sliced.

How to Roast Zucchini

  1. Preheat the oven and prepare baking sheets: Preheat the oven to 450°F and line baking sheets with foil. You may only need just one baking sheet, but for 2 pounds of zucchini, I usually need two.
  2. Prepare the zucchini: Wash and dry each zucchini, then trim the woody base, or end, from each. There is no need to peel before cooking, zucchini skin is very thin and actually helps prevent the zucchini from becoming too mushy. Cut zucchini into 1/2-inch thick rounds.
  3. Season: Toss the zucchini with olive oil, salt, black pepper, garlic powder, smoked paprika, and 1/4 cup of grated parmesan cheese in a large bowl.
  4. Arrange the zucchini slices on the prepared baking sheets: Place them in a single, non-overlapping layer. Top with the remaining 1/2 cup of Parmesan cheese.
  5. Roast the zucchini: Roast for 6-8 minutes, then broil for an additional 2 minutes.

Roasted Zucchini Recipe Tips

  • You can make this recipe with zucchini and yellow squash.
  • Slice the zucchini so that they are roughly equal thickness – about 1/2 inch. This allows for even cooking.
  • Allow space between each zucchini on the baking sheet. This helps prevent steaming and sogginess.
  • Try adding different seasonings like Italian seasoning or taco seasoning.

    Hey Jess

    Thanks!

    Really lovely flavours. I could eat these every night. I even added some left over broccoli and gave it the same treatment.

    How much longer should I cook them to get crispy zucchini chips?

    1. Jessica Randhawa says:

      Thank you so much, Sharon! I love that you tried the same treatment with broccoli too. For crispy zucchini chips, I would not simply cook these 1/2-inch slices longer, since they will tend to soften before they crisp. I have not tested this recipe as chips, but I would slice the zucchini much thinner and keep a close eye on them since the Parmesan can brown quickly. 🙂
