how long to bake a chicken breast
Bake boneless chicken breasts for about 20–25 minutes at 400°F (205°C), or 18–22 minutes at 425°F (220°C), until they reach an internal temperature of 165°F (74°C) at the thickest part.
How Long to Bake a Chicken Breast
(Quick Scoop guide with all the practical details you actually need in the kitchen.)
The Core Answer (Quick Scoop)
- Time range (boneless, skinless):
- At 375°F (190°C): about 20–30 minutes, depending on thickness.
* At 400°F (205°C): about 20–25 minutes for an average breast.
* At 425°F (220°C): about 18–22 minutes for a medium breast.
* At 450°F (230°C): about 20 minutes for ~8 oz breasts, up to ~30 minutes for very large ones.
- Food-safety rule: Always cook to an internal temperature of 165°F (74°C) , checked with a meat thermometer in the thickest part.
- Thickness guide (at 400–425°F):
* 1/2 inch thick: 16–18 minutes.
* 3/4 inch thick: 20–22 minutes.
* 1 inch thick: 24–26 minutes.
If you remember nothing else: aim for 18–25 minutes at a hot oven (400–425°F), then confirm doneness with a thermometer.
Mini Section: Basic Step‑By‑Step
- Preheat the oven
- Choose 400°F or 425°F for juicy, slightly browned chicken.
- Prep the chicken
- Pat dry, rub with oil, season with salt, pepper, and any spices.
- For even cooking, pound thick ends a bit so the breast is a more even thickness.
- Bake (uncovered)
- Place on a baking sheet or in a baking dish, not crowded.
- Bake according to thickness/time above until it hits 165°F (74°C).
- Rest the chicken
- Let it rest 5–10 minutes loosely covered with foil so juices redistribute and stay in the meat.
Mini Section: Bone‑In vs Boneless
- Boneless, skinless breasts
- Cook faster: about 20–30 minutes at 350–425°F depending on size and oven temp.
- Bone‑in breasts
- Need more time: about 30–40 minutes at 350°F for 6–8 oz pieces.
* Again, you’re done when the thickest part at the bone reaches 165°F.
Mini Section: Why Times Vary (And How Not to Dry It Out)
Even if two recipes say “20 minutes,” ovens and chicken sizes differ, which is why relying only on minutes can lead to dry meat.
- Things that change the time:
- Size and thickness of the breast.
- Starting temperature (cold from fridge vs closer to room temp).
- Oven accuracy and whether you’re using a glass or metal pan.
- Easy tips for juicier results:
- Bake at a relatively high temp (400–450°F) for a shorter time.
* Do not overbake; pull right at 165°F.
* Let it rest before slicing so juices don’t spill out on the cutting board.
A simple practical example: a medium, about 8‑ounce boneless breast baked at 450°F is typically ready in roughly 20 minutes once it hits 165°F inside.

| Chicken type | Oven temp | Approx. time | Key check |
|---|---|---|---|
| Boneless, 1/2" thick | 400–425°F | 16–18 min | 165°F internal |
| Boneless, 3/4" thick | 400–425°F | 20–22 min | 165°F internal |
| Boneless, 1" thick | 400–425°F | 24–26 min | 165°F internal |
| Boneless, ~8 oz | 450°F | ~20 min | 165°F internal |
| Bone‑in breast, 6–8 oz | 350°F | 30–40 min | 165°F internal |
TL;DR: For a typical boneless chicken breast, set your oven to 400–425°F, bake about 20 minutes, and trust your thermometer to tell you when it’s perfectly done at 165°F. Information gathered from public forums or data available on the internet and portrayed here.
