Why You’ll Love This Recipe
I love how quick and effortless this recipe is to prepare. I only need a handful of pantry staples, and the oven does most of the work. The zucchini comes out tender on the inside with slightly crisp, golden edges on the outside. I also appreciate how versatile this dish is. I can serve it alongside grilled meats, pasta, or even add it to salads and wraps. It is light, flavorful, and perfect for busy weeknights.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
2 medium zucchini
2 tablespoons olive oil
1/2 teaspoon garlic powder
1/2 teaspoon dried Italian seasoning
1/4 teaspoon salt
1/4 teaspoon black pepper
2 tablespoons grated Parmesan cheese (optional)
Directions
I start by preheating the oven to 425°F (220°C). I wash and dry the zucchini, then slice them into even rounds about 1/4 inch thick to ensure they cook evenly.
I place the slices in a large bowl and drizzle them with olive oil. I sprinkle in the garlic powder, Italian seasoning, salt, and black pepper. I toss everything together until the slices are evenly coated.
Next, I arrange the zucchini slices in a single layer on a baking sheet lined with parchment paper. I make sure they are not overlapping so they roast properly instead of steaming. If I am using Parmesan cheese, I sprinkle it evenly over the top.
I roast the zucchini for 18–22 minutes, or until they are tender and lightly golden. If I want extra browning, I broil them for the last 2–3 minutes while keeping a close eye on them.
I remove them from the oven and serve immediately for the best texture and flavor.
Servings and timing
This recipe makes about 4 servings as a side dish.
Prep time: 10 minutes
Cook time: 20 minutes
Total time: 30 minutes
Variations
I sometimes add a pinch of red pepper flakes for a little heat. When I want a smoky flavor, I sprinkle in some smoked paprika. I also like using fresh herbs such as thyme or basil after roasting for a fresh finish. For a dairy-free version, I simply skip the Parmesan or use a plant-based alternative. If I want extra crispiness, I coat the slices lightly in seasoned breadcrumbs before roasting.
storage/reheating
I store leftover roasted zucchini in an airtight container in the refrigerator for up to 3 days. To reheat, I place them in the oven at 375°F (190°C) for about 8–10 minutes to help them regain some texture. I can also reheat them in a skillet over medium heat for a few minutes. While I can use the microwave, I find that it makes the zucchini softer.
FAQs
Can I make this recipe ahead of time?
I prefer serving roasted zucchini fresh, but I can slice and season the zucchini a few hours ahead and keep them refrigerated until I am ready to roast.
Why is my zucchini soggy?
If my zucchini turns out soggy, it is usually because the slices were too thick or overcrowded on the baking sheet. I make sure to keep them in a single layer with space between each slice.
Can I use yellow squash instead?
Yes, I can easily substitute yellow squash for zucchini or use a combination of both for added color.
Do I need to peel the zucchini?
No, I leave the skin on because it helps the slices hold their shape and adds extra nutrients.
Can I cook this in an air fryer?
Yes, I can cook the slices in an air fryer at 400°F (200°C) for about 8–10 minutes, shaking the basket halfway through for even cooking.
Conclusion
I enjoy how simple and reliable these easy roasted zucchini slices are. With just a few ingredients and a short cooking time, I get a flavorful and healthy side dish that works with almost any meal. It is one of my favorite ways to prepare fresh zucchini quickly and deliciously.
