The baking time for chicken depends on the cut and size. For boneless chicken breasts, it typically takes about:
- Small breasts (around 5 oz): 18 to 20 minutes at 425°F (220°C)
- Medium breasts (around 7 oz): 20 to 22 minutes at 425°F (220°C)
- Large breasts (around 9 oz): 22 to 25 minutes at 425°F (220°C)
For a whole roasted chicken or bone-in pieces, the baking time can be significantly longer; for example, about 1 hour and 15 minutes at a similar temperature, until the internal temperature reaches 165°F (74°C). The key is to cook the chicken until it reaches an internal temperature of 165°F (75°C) and the juices run clear. Letting the chicken rest after baking for 5 to 10 minutes is also recommended for juiciness. For boneless chicken breasts, cooking at a higher temperature (around 425 to 450°F) for a shorter time (about 18-25 minutes depending on size) helps keep the meat juicy without drying it out.
