how long do you cook chicken breast in the oven

For standard boneless, skinless chicken breasts, a good rule of thumb is about 18–25 minutes in a hot oven, as long as you cook them until they reach 165°F (75°C) in the thickest part.

Quick Scoop

• At 400°F (200°C):
  • Average boneless breast (around 6–8 oz, 2–3 cm thick) usually takes 18–20 minutes.
  • Slightly larger or thicker pieces may need 20–25 minutes.
• At 350°F (180°C):
  • Plan on roughly 22–25 minutes for average boneless breasts.
• Always cook to 165°F (75°C) internal temperature rather than by time alone, since size and thickness change everything.

Simple Step‑By‑Step

1. Preheat oven to 400°F (200°C).
2. Pat chicken dry, rub with oil, season with salt, pepper, and any spices you like.
3. Place breasts in a single layer on a baking tray or in a baking dish.
4. Bake 18–20 minutes for average‑size breasts.
5. Check the thickest part with a meat thermometer; if it has not yet reached 165°F (75°C) , return to the oven and check every 3–5 minutes.
6. Let rest 5–10 minutes before slicing so the juices redistribute and the meat stays moist.

Quick Variations

• Lower temp, gentler cook (juicier, slower)
  • 320–350°F (160–180°C): about 22–30 minutes , depending on thickness.
• Higher temp, faster cook (more browning, watch closely)
  • 425°F (220°C): about 15–18 minutes for medium breasts.

Safety First

• Do not rely on color or juices alone; use a thermometer for food safety.
• If you cut in and it looks slightly undercooked, put it back in the oven for a few more minutes rather than trying to “guess” next time.
