how long to bake chicken breast at 350

For standard boneless chicken breasts, baking at 350°F usually takes about 25–35 minutes, but the real key is cooking to an internal temperature of 165°F rather than a strict time.

How long to bake chicken breast at 350°F

• For small to medium boneless, skinless breasts (about 6–8 ounces each): plan on roughly 25–30 minutes at 350°F, checking for doneness around the 20–25 minute mark.

• For larger boneless breasts (10–12 ounces): 30–35 minutes is typical; very large pieces (12–16+ ounces) can run 40–45 minutes.

• For bone‑in, skin‑on chicken breasts: expect about 50–60 minutes at 350°F because the bone slows cooking.

Always use an instant‑read thermometer and pull the chicken when the thickest part reaches 165°F, then let it rest about 5–10 minutes so the juices redistribute.

Quick Scoop

• Preheat oven to 350°F.
• Season chicken and place in a single layer in a baking dish or on a sheet pan.
• Bake:
  • 6–8 oz boneless breasts: ~25–30 minutes.
  • 10–12 oz boneless breasts: ~30–35 minutes.
  • Bone‑in breasts: ~50–60 minutes.
• Check for 165°F internal temperature at the thickest part; if it has not reached that, continue baking in 5‑minute increments.

• Rest 5–10 minutes before slicing for juicier meat.

Simple example

If you have two average boneless breasts (about 7 ounces each), you could: season them, bake at 350°F for 25 minutes, then check with a thermometer; if they are around 160°F, give them another 3–5 minutes until they reach 165°F, then rest before serving.
