How Long to Cook Chicken Breast at Every Temperature
Overcooked chicken breast is one of the most common kitchen mistakes. The difference between juicy and dry often comes down to just a few minutes. This guide gives you exact times for every method and oven temperature.
The Only Rule That Matters
Chicken breast is done when the thickest part reaches 165°F (74°C) internally. This is the USDA safe temperature. A meat thermometer is the only reliable way to know — color, juices, and timing are all secondary indicators.
Baked Chicken Breast: Time by Oven Temperature
| Oven Temp | Boneless (6 oz) | Boneless (8 oz) | Bone-in |
|---|---|---|---|
| 350°F (177°C) | 25–30 min | 30–35 min | 45–55 min |
| 375°F (190°C) | 20–25 min | 25–30 min | 40–50 min |
| 400°F (204°C) | 18–22 min | 22–26 min | 35–45 min |
| 425°F (218°C) | 15–18 min | 18–22 min | 30–40 min |
Always let chicken rest 5 minutes after removing from the oven. Internal temperature will rise another 3–5°F during resting.
The 400°F Sweet Spot
Most chefs prefer 400°F for baked chicken breast. It's hot enough to get light browning on the outside while keeping the inside juicy. At 350°F the chicken tends to steam rather than roast, which can result in a less flavorful exterior.
Pan-Seared Chicken Breast
For a 6–8 oz boneless breast: heat oil in a skillet over medium-high heat. Cook 6–7 minutes per side without moving. Rest 5 minutes. The key is not moving the chicken so it develops a proper sear.
Grilled Chicken Breast
Preheat grill to medium-high (around 400°F). Grill 6–8 minutes per side for a boneless breast. Use the same 165°F internal temperature rule.
How to Keep Chicken Breast Juicy
Pound chicken to an even thickness before cooking — this solves the problem of the thin end drying out before the thick end is cooked. A quick brine (1 tablespoon salt per cup of water, 30 minutes) also helps retain moisture significantly.
