You’ll usually bake chicken between 15 and 45 minutes, depending mainly on the cut, thickness, and oven temperature, and it’s safely done when the center reaches 165°F (74°C).

How Long to Bake Chicken (Quick Scoop)

Safe internal temperature (most important)

No matter the cut or oven temp, chicken is done when the thickest part reaches 165°F (74°C) and the juices run clear.

Use an instant‑read thermometer in the thickest part (avoiding bone) for accuracy.

Typical baking times by cut

Boneless, skinless chicken breasts

  • At 425–450°F (220–230°C):
    • Medium breasts (about 8 oz / 225 g): 18–20 minutes.
* Larger (10–12 oz / 280–340 g): 20–30 minutes.
  • At 350°F (175°C):
    • About 30–45 minutes, depending on thickness, until 165°F.

High heat for a shorter time helps keep breasts moist and juicy rather than dry.

Bone‑in pieces (thighs, drumsticks, bone‑in breasts)

  • At 350°F (175°C):
    • About 40–50 minutes for bone‑in pieces, until golden and 165°F inside.
  • At 400°F (200°C):
    • Many home cooks report roughly 30–40 minutes for medium pieces, but you still go by the thermometer for doneness.

Bone and dark meat usually mean a slightly longer cook time than boneless breasts of the same size.

Whole chicken (for context)

  • At 350°F (175°C):
    • Common guideline is roughly 20 minutes per pound plus a bit extra, but the real check is 165°F in the thickest part of the breast and inner thigh.

Reddit cooks often emphasize that time is only a starting point and the thermometer is “magic” for getting this right.

“High and fast” vs “lower and slower”

  • Higher temp (425–450°F):
    • Pros: Juicier breast meat, better browning, shorter cook time.
* Example: 18–20 minutes at 425°F for medium breasts.
  • Moderate temp (350°F):
    • Pros: Forgiving and familiar, good for whole chicken or big bone‑in pieces.
    • Example: 30–45 minutes for breasts or 40–50 minutes for bone‑in pieces.

Many home and pro cooks now lean toward high heat + thermometer instead of “low and slow” for chicken, because low and slow can make it dry and rubbery.

Cut Oven temperature Approx. time Doneness check
Boneless, skinless breasts (medium, ~8 oz) 425–450°F (220–230°C) 18–20 minutes 165°F in thickest part, juices clear
Boneless, skinless breasts (large, 10–12 oz) 425–450°F (220–230°C) 20–30 minutes 165°F in thickest part
Boneless, skinless breasts 350°F (175°C) 30–45 minutes 165°F, no pink in center
Bone‑in pieces (thighs/drumsticks) 350°F (175°C) 40–50 minutes 165°F at thickest part near bone
Whole chicken 350°F (175°C) Roughly 20 min per lb (guide only) 165°F in breast and inner thigh

Little “story” to remember it

Think of a weeknight where you get home hungry and toss a couple of seasoned chicken breasts in a hot oven.
You crank it to a high temp, set a 20‑minute timer, and when it rings you stab the thickest part with your thermometer: it hits 165°F and the juices run clear, so you let it rest a few minutes and dinner stays juicy instead of dry.

TL;DR

  • Use 425–450°F for juicy, browned boneless breasts: 18–20 minutes for medium, up to ~30 minutes for large.
  • Use about 40–50 minutes at 350°F for bone‑in pieces.
  • Always confirm with a thermometer: 165°F (74°C) in the thickest part is the non‑negotiable safety check.
