Ingredients You’ll Need
- 1 lb zucchini: Fresh and firm zucchinis work best. Look for those with a vibrant color, avoiding any with soft spots.
- 2 tbsp olive oil: A good-quality extra virgin olive oil adds a rich depth of flavor. Feel free to substitute with avocado oil if you prefer.
- 1 tbsp balsamic vinegar: This adds a tangy sweetness that balances the savory notes. You can also use red wine vinegar for a different twist.
- 1 tsp garlic powder: If you’re a garlic lover, you might want to increase this to 1 ½ tsp for a more robust flavor.
- 1/2 tsp dried thyme: This herb complements the zucchini beautifully. If you don’t have dried thyme, Italian seasoning would work splendidly.
- 1 tsp dried basil: Fresh basil is wonderful if you have it! Just keep in mind to roughly triple the amount.
- 1/2 tsp crushed red pepper flakes: Perfect for a bit of heat. Adjust according to your spice tolerance.
- 1/2-1 tsp salt (more or less to taste): Start with half a teaspoon and add more, if needed, after roasting.
- 1/4 tsp black pepper: Freshly cracked black pepper adds a slight kick; it’s best to crack it just before using.
- 1/2 cup grated parmesan cheese: Always choose freshly grated cheese from the block, as it melts beautifully and enhances the flavor like no other.
How to Make Roasted Zucchini
- Preheat the oven: Set your oven to 475℉. For perfect roasting, use a large rimmed baking sheet. Avoid lining it with parchment paper, as this can prevent browning and crispiness; simply grease it lightly with olive oil.
- Prepare the zucchini: Wash and pat dry the zucchini. Trim off the ends, and slice it into approximately 1/4-1/2 inch thick rounds. Remember, thinner slices will yield softer zucchini, while thicker slices will be crunchier!
- Mix the seasoning: In a mixing bowl, combine the sliced zucchini with 2 tablespoons olive oil, 1 tablespoon balsamic vinegar, and the garlic powder, thyme, basil, red pepper flakes, salt, and black pepper. Toss until every piece is well-coated.
- Spread on the baking sheet: Arrange the seasoned zucchini on the prepared baking sheet in one single layer. Make sure to leave a little space between each piece to ensure even roasting.
- Add the parmesan: Generously top each zucchini slice with grated parmesan cheese. Watching it melt and bubble in the oven makes the cooking process rewarding!
- Roast to perfection: Place the baking sheet in the preheated oven and roast the zucchini for 20-24 minutes, depending on your desired doneness. Look for golden edges and tender slices.
Storing & Reheating
To enjoy leftovers, let your roasted zucchini cool completely before placing it in an airtight container. Store it in the refrigerator for up to 3-4 days. If you’d like to freeze, layer the zucchini in a freezer-safe bag or container, making sure to lay them flat to minimize space. It can last up to 3 months in the freezer. Reheat in the oven at 350℉ for about 10-15 minutes until warmed through, but expect the texture to soften slightly—adding a sprinkle of fresh parmesan when reheating can help refresh the flavor!
Chef’s Helpful Tips
- Avoid overloading the baking sheet. Crowding will lead to steaming instead of roasting, resulting in soggy zucchini.
- If you prefer a deeper flavor, consider adding a pinch of smoked paprika or even some fresh herbs like parsley or cilantro before serving.
- For a Mediterranean twist, add sun-dried tomatoes or olives just before serving.
- Ensure your zucchini is of consistent thickness for even cooking, which makes all the difference in texture.
- Don’t rush! Letting the zucchini roast until caramelized will amplify the natural sugars and deepen the dish’s flavor.
This parmesan roasted zucchini is more than just a side dish; it’s your answer to the age-old question of how to enjoy those abundant garden zucchinis or fresh market finds. Versatile and flavorful, it invites you to play with the concepts of roasting and seasoning, so feel free to adapt it to suit any of your cravings or occasion.
