Data-assisted guide Updated Jun 2026 Built from structured cooking data and official food-safety guidance, written in our own words.

Bake chicken breasts for 18–22 minutes at 200°C (fan 180°C / 392°F, gas mark 6).

Method

  1. Bring the chicken to room temperature for a few minutes and rub with a little oil and seasoning.
  2. Preheat the oven to 200°C (fan 180°C, gas mark 6).
  3. Bake for 18–22 minutes for a medium breast (about 180g), then rest for 5 minutes.

How to tell it's cooked

  • Juices run clear when pierced at the thickest point.
  • The meat is white throughout with no pink.
  • A thermometer reads at least 75°C in the centre.
