The baking time for boneless chicken breasts depends on the oven temperature and the size/thickness of the breasts. Here are the main guidelines:
- At 425°F (220°C), bake for about 12-25 minutes:
- 5 oz breast: 10-13 minutes
- 7 oz breast: 14-18 minutes
- 10 oz breast: 19-24 minutes
- 12 oz breast: 22-25 minutes
- At 400°F, bake for about 20 minutes.
- At 350°F (177°C), bake a 4-ounce breast for 25-30 minutes.
The key is to cook the chicken until its internal temperature reaches 165°F (74°C) for safety and juiciness. Using a meat thermometer is the best way to ensure doneness without overcooking
. To keep chicken breasts juicy, you can pound them to even thickness, rub with oil and seasonings, and avoid overbaking. Let the chicken rest for 3-5 minutes after baking to allow the temperature to rise slightly and the juices to redistribute
. In summary, baking boneless chicken breasts at 425°F for about 12-25 minutes depending on size, until the internal temperature hits 165°F, is a reliable method to achieve juicy and fully cooked chicken
