Super simple oven-roasted zucchini slices seasoned with just salt and pepper. Roast at high heat for tender centers and crispy, golden edges in about 20 minutes.
Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper or foil for easy cleanup.
Slice the zucchini into rounds about 1/4-inch thick. Arrange in a single layer on the baking sheet (don’t crowd, or they’ll steam).
Drizzle the zucchini with olive oil. Sprinkle evenly with salt and black pepper. Flip or toss to coat both sides.
Roast for 15–20 minutes, flipping halfway through, until the edges are golden and the centers are tender.
Let cool for 1–2 minutes, then serve warm.
Notes
Slice thickness: Aim for ~1/4 inch. Too thin can burn; too thick can turn soggy.Don’t salt early: Salt right before roasting to reduce watery zucchini.Leftovers: Refrigerate in an airtight container up to 3 days. Reheat on a baking sheet at 350°F (175°C) for about 5 minutes to warm and re-crisp.Oil swaps: Avocado or vegetable oil also works.
