Crispy Roasted Zucchini with Parmesan and Lemon-Tahini
Stop eating soggy squash. This roasted zucchini recipe uses high heat and a parmesan crust for a golden, crispy finish, topped with a bright lemon-tahini drizzle.
Most people fail at roasted zucchini because they treat it like a hardy root vegetable. Zucchini is over 90 percent water; if you crowd the pan or cook it at a low temperature, it steams into a mushy pile. This recipe fixes that with a high-heat blast and a strategic parmesan crust that acts as a moisture barrier.
To achieve the best oven roasted zucchini, you need a hot rimmed baking sheet and a layer of parchment paper. The parchment prevents sticking while allowing the underside of the squash to brown deeply. We finish the dish with a nutty lemon-tahini drizzle that cuts through the richness of the cheese.
Whether you are looking for a quick weeknight side or a way to use up a summer garden haul, this roasted zucchini technique will become your new standard. No more watery vegetables—just concentrated flavor and a satisfying crunch.
Ingredients
The Vegetables
- 3 medium zucchini (about 1.5 lbs / 680g), ends trimmed
- 2 tablespoons extra-virgin olive oil
- 1/2 teaspoon kosher salt
- 1/4 teaspoon freshly cracked black pepper
- 1/2 teaspoon garlic powder
The Crust
- 1/3 cup (35g) freshly grated Parmesan cheese
- 2 tablespoons panko breadcrumbs (optional, for extra crunch)
Lemon-Tahini Drizzle
- 2 tablespoons well-stirred tahini
- 1 tablespoon fresh lemon juice
- 1 teaspoon maple syrup or honey
- 1-2 tablespoons warm water to thin
- Pinch of red pepper flakes
Instructions
- 1
Preheat your oven to 425°F (220°C) and line a large rimmed baking sheet with parchment paper.
- 2
Slice the zucchini into 1/2-inch thick rounds or half-moons. Ensure they are uniform so they cook at the same rate.
- 3
Toss the zucchini in a large bowl with the olive oil, salt, pepper, and garlic powder until every piece is slicked with oil.
- 4
Arrange the slices on the prepared baking sheet in a single layer. Do not let them overlap, or they will steam instead of roast.
- 5
Sprinkle the Parmesan cheese (and panko, if using) evenly over the top of the zucchini slices.
- 6
Roast for 15 to 18 minutes. For a deeper crust, flip the oven to broil for the final 60 seconds, watching closely to prevent burning.
- 7
Whisk the tahini, lemon juice, maple syrup, and red pepper flakes in a small bowl while the zucchini roasts. Add warm water 1 teaspoon at a time until it reaches a pourable consistency.
- 8
Remove the zucchini from the oven when the cheese is golden brown and the edges are caramelized.
- 9
Transfer to a serving platter and drizzle immediately with the lemon-tahini sauce.
Tips
- → Pat the zucchini slices dry with a paper towel before tossing them in oil to remove excess surface moisture.
- → Don't salt the zucchini too early; salt draws out water. Season and roast immediately for the best texture.
- → Use a metal baking sheet rather than a glass dish. Metal conducts heat faster, which is essential for that golden-brown sear.
FAQ
Why does my roasted zucchini turn out soggy?
Sogginess is usually caused by overcrowding the pan or roasting at too low a temperature. Make sure there is space between each slice so the steam can escape, and keep the heat at 425°F.
Do I need to peel zucchini before roasting?
No, the skin is thin and edible. It also helps the slices hold their shape during the high-heat roasting process.
Can I make this roasted zucchini recipe dairy-free?
Yes, you can substitute the Parmesan with nutritional yeast or a vegan parmesan alternative, or simply omit it and increase the panko breadcrumbs for crunch.
How do I reheat leftovers without them getting mushy?
Avoid the microwave. Reheat leftover zucchini in a hot skillet over medium-high heat for 2 minutes or in an air fryer at 375°F for 3 minutes.
