To bake chicken breast, the cooking time depends primarily on the size and thickness of the breasts as well as the oven temperature. Here are general guidelines based on multiple reliable sources:
- Preheat your oven to between 400°F (200°C) and 450°F (230°C) for best results.
- For medium-sized chicken breasts (around 7 ounces), bake for about 20 to 25 minutes.
- Smaller breasts (about 5 ounces) typically take 18 to 20 minutes.
- Larger breasts (9 ounces or more) require 22 to 25 minutes or slightly longer.
- Thinner breasts (around 1/2 inch thick) may take 16 to 18 minutes, while thicker ones (up to 1 inch) can take 24 to 26 minutes.
- The key indicator of doneness is an internal temperature of 165°F (75°C), measured at the thickest part with a meat thermometer.
- Let the chicken rest for 5 to 10 minutes after baking to retain juices and ensure tenderness.
For example, one detailed method suggests baking at 450°F for 15-18 minutes, checking that the chicken is no longer pink inside and reaches 165°F internally
. Another approach recommends baking at 400°F for 20-25 minutes depending on size, with resting afterward
. Lower temperatures like 350°F require longer cooking times, around 25-30 minutes for a 4-ounce breast
. In summary, baking chicken breast generally takes about 18 to 25 minutes at 400-450°F, adjusted for size and thickness, with the internal temperature reaching 165°F to ensure safety and juiciness
