Most recipes call for baking or roasting zucchini at 375–425°F (190–220°C) , with 400–425°F being the most popular for a golden, slightly crispy finish.

Quick Scoop

  • Ideal baking temp for zucchini: about 400–425°F for 15–25 minutes, depending on slice thickness.
  • For gentler cooking, you can go as low as 350–375°F , but it may take closer to 20–30 minutes to soften.

Recommended temperatures by style

Style / texture| Oven temp (°F)| Typical time range
---|---|---
Lightly golden “baked” side| 350–375°F| 20–30 minutes 35
Roasted, tender with caramel edge| 400°F| 12–20 minutes 34
Extra‑crisp roasted zucchini| 425–450°F| 15–25 minutes (watch closely) 34

A few practical tips

  • Slice zucchini 1/4 to 1/3 inch thick so it cooks evenly without turning to mush.
  • Arrange in a single layer on the sheet; overcrowding steams the zucchini and keeps it soft instead of roasted‑crisp.
  • If you want extra color on top, finish with 2–3 minutes under the broiler after baking.

If you tell me how you plan to use the zucchini (cheesy gratin, puree, “zoodles,” etc.), I can suggest the exact temp and time tailored to that dish.
