Basic Recipe: How to Cook Zucchini in Oven (Simple Roasted Zucchini)
Ingredients:
- 3 medium zucchini
- 2 tablespoons olive oil
- Salt and pepper to taste
Instructions:
- Preheat the oven to 425°F (220°C). This high temperature helps in caramelization and reduces sogginess.
- Prepare the zucchini: Slice into half-moons or rounds, about 1/4-inch thick.
- Toss with oil and seasonings: In a large bowl, toss the zucchini with olive oil, salt, and pepper. Make sure each piece is coated.
- Arrange on a baking sheet: Line a baking tray with parchment paper or foil. Spread the zucchini in a single layer, with space between pieces to allow roasting (not steaming).
- Roast in the oven for 20–25 minutes. Flip halfway through. Roast until edges are golden and slightly crisp.
- Serve warm, garnished with fresh herbs, lemon juice, or Parmesan cheese if desired.

FAQs About Cooking Zucchini in the Oven
1. Should I peel zucchini before roasting?
No, the skin is tender and edible. It also helps the zucchini hold its shape during roasting.

This is usually due to:
