Ingredients You’ll Need

1 lb zucchini: Choose firm, fresh zucchini for the best texture and flavor. Smaller, younger zucchinis tend to be sweeter.
2 tbsp olive oil: Adds richness and helps the seasonings stick. You can substitute it with avocado oil if desired.
1 tbsp balsamic vinegar: This gives a nice tangy punch that balances the dish. Feel free to use apple cider vinegar for a different flavor.
1 tsp garlic powder: For a burst of savory flavor without the fuss of fresh garlic. If you prefer fresh garlic, about 2-3 cloves minced will work wonderfully.
1/2 tsp dried thyme: This herb adds an earthy note. If you have fresh thyme, it can be used as a direct substitute.
1 tsp dried basil: Perfect for that Italian flair. You can switch to fresh basil, but add it at the end to prevent burning.
1/2 tsp crushed red pepper flakes: A little kick to elevate the flavors. Adjust according to your spice preference.
1/2-1 tsp salt: Season to taste. Always start with a smaller amount and adjust as needed.
1/4 tsp black pepper: Offers a subtle warmth and enhances the overall flavor.
1/2 cup grated parmesan cheese: Freshly grated is best for melting and flavor. If you’re walking on the dairy-free path, nutritional yeast could be an interesting replacement.

How to Make Roasted Zucchini

Preheat the oven: Set your oven to 475℉. A hot oven ensures crispy edges and prevents sogginess, which is key to great roasted zucchini. If you prefer, lightly grease your baking sheet with olive oil to avoid sticking. However, for a deeper golden color, skipping parchment paper is ideal.
Prepare the zucchini: Wash each zucchini thoroughly and pat dry with a towel. Trim off the ends and slice the zucchini into about 1/4-1/2 inch thick slices. Keep in mind that thicker slices yield a crunchier texture while thinner slices tend to be softer.
Season the zucchini: In a large bowl, mix the zucchini slices with 2 tablespoons of olive oil, 1 tablespoon of balsamic vinegar, 1 teaspoon of garlic powder, 1/2 teaspoon of dried thyme, 1 teaspoon of dried basil, 1/2 teaspoon of crushed red pepper flakes, salt, and pepper until well coated.
Arrange on baking sheet: Spread the seasoned zucchini in a single layer on your prepared baking sheet, making sure to leave some space between each slice for even roasting.
Add parmesan cheese: Sprinkle 1/2 cup of grated parmesan cheese over each slice, ensuring an even distribution for that delicious cheesy crust.
Roast in the oven: Place the baking sheet in the preheated oven and roast the zucchini for about 20-24 minutes. Check for doneness; you’re looking for a caramelized edge and tender center. If you prefer them crunchier, opt for the lesser time.

Storing & Reheating

To store your roasted zucchini, allow it to cool completely before placing it in an airtight container. It should last in the refrigerator for up to 4 days. If you want to freeze it, transfer the roasted zucchini to a freezer-safe container after they’ve cooled and enjoy within 3 months. When reheating, pop it into a 350℉ oven for about 10 minutes or until heated through. Keep in mind that reheated zucchini can lose some texture, so adding a sprinkle of fresh herbs or a splash of balsamic vinegar can refresh the flavors!

Chef’s Helpful Tips

Avoid overcrowding the baking sheet; this will help your zucchini roast instead of steam.
If you like a pronounced garlic flavor, feel free to increase the amount of garlic powder used, or swap it for minced garlic when you mix the ingredients.
For extra texture, don’t hesitate to sprinkle some breadcrumbs on top before adding parmesan for a delicious crunch!
To enhance the flavor even more, try adding a bit of lemon zest or juice just before serving.
If you’re making these ahead of time, roast them a bit less, then store and finish them off in the oven when you’re ready to serve.

Roasted zucchini, while simple, is incredibly versatile. This dish can brighten up any meal, from Taco Tuesday to Sunday dinner. Feel free to get creative with herbs or add sautéed onions for an additional flavor boost. You’ll love how well this dish complements so many different main courses!
