How long to cook chicken breast in oven is one of the most searched cooking questions for a reason. Chicken breast is lean, healthy, affordable—and incredibly easy to overcook. One extra five minutes can turn juicy chicken into something dry and rubbery.
This guide is designed to remove all guesswork. You’ll learn exact cooking times, best oven temperatures, how thickness affects baking, and how to tell when chicken is safely done—all explained in a simple, human way that actually works in real kitchens.
Whether you’re cooking dinner on a busy weeknight or meal-prepping for the week, this article gives you clear answers you can trust.
How Long to Cook Chicken Breast in the Oven (Quick Answer)
If you’re in a hurry, here’s the short, reliable answer most home cooks need:
Boneless, skinless chicken breasts baked at 400°F (200°C) take 20–25 minutes, depending on thickness.
Chicken is fully cooked when the internal temperature reaches 165°F (74°C).
That’s the safety rule. Everything else—juiciness, texture, flavor—depends on how well you manage time, temperature, and thickness.
Chicken Breast Oven Cooking Time Chart (By Temperature)
Cooking temperature has a direct impact on how long chicken breast takes to bake. Lower heat takes longer but is more forgiving. Higher heat cooks faster but requires attention.
| Oven Temperature | Cooking Time | Best For |
| 350°F (175°C) | 25–30 minutes | Very juicy, slower cooking |
| 375°F (190°C) | 22–27 minutes | Balanced, beginner-friendly |
| 400°F (200°C) | 20–25 minutes | Most popular & reliable |
| 425°F (220°C) | 18–22 minutes | Faster cooking, good browning |
| 450°F (230°C) | 15–18 minutes | Thin breasts only, watch closely |
No matter the temperature, 165°F internal temperature is what matters most.
How Long to Cook Chicken Breast Based on Thickness
Thickness is the #1 reason chicken breast overcooks. Two breasts can weigh the same but cook very differently if one is thicker in the center.
Thin Chicken Breasts (½–¾ inch)
Thin chicken breasts cook quickly and dry out fast.
- Average time at 400°F: 15–18 minutes
- Best cooked at slightly higher heat for shorter time
- Ideal for slicing or salads
Average Chicken Breasts (About 1 inch)
This is the most common size sold in stores.
- Average time at 400°F: 20–25 minutes
- Most forgiving size
- Best balance of moisture and structure
Thick Chicken Breasts (1½ inches or more)
Thick breasts are where most people struggle.
- Average time at 400°F: 25–30 minutes
- Pound slightly or lower oven temp
- Thermometer is essential
Pro tip: Lightly pounding chicken to an even thickness dramatically improves even cooking and juiciness.
Boneless vs Bone-In Chicken Breast Cooking Time
Boneless, Skinless Chicken Breast
This is what most recipes and weeknight meals use.
- Cooks faster
- Dries out more easily
- Best cooked at 375–400°F
Bone-In Chicken Breast
Bone-in chicken takes longer but stays juicier.
- Add 10–15 extra minutes
- Better moisture retention
- Ideal for roasting at 375°F
Bone slows heat transfer, which protects the meat—but increases total cooking time.
Best Oven Temperature for Chicken Breast (What Actually Works)
There is no single “perfect” temperature, but some choices work better than others depending on your goal.
- 350°F: Safest for beginners, hardest to dry out
- 375–400°F: Best balance of time, juiciness, and texture
- 425–450°F: Fast, flavorful, but unforgiving
For most people, 400°F is the sweet spot. It’s fast enough for weeknights and hot enough to develop flavor without drying out the chicken.
How Long to Cook Chicken Breast in Oven at 350°F
If you prefer lower heat:
- 25–30 minutes for boneless chicken breast
- Excellent for thicker cuts
- Less browning, very juicy
This temperature is ideal if you’re multitasking or nervous about overcooking.
How Long to Cook Chicken Breast in Oven at 375°F
This is one of the most forgiving temperatures.
- 22–27 minutes
- Good for beginners
- Even cooking with less risk
If you’re unsure which temperature to choose, 375°F is a safe bet.
How Long to Cook Chicken Breast in Oven at 400°F
This is the most commonly recommended option.
- 20–25 minutes
- Works for most thicknesses
- Best mix of speed and moisture
If you only remember one number, remember this one.
How Long to Cook Chicken Breast in Oven at 425°F
Higher heat shortens cooking time but increases risk.
- 18–22 minutes
- Best for thinner breasts
- Watch closely after 15 minutes
This temperature works well when you want browning without frying.
How to Tell When Chicken Breast Is Fully Cooked
Internal Temperature (The Gold Standard)
Chicken breast is done when it reaches 165°F (74°C) at the thickest part.
- Insert thermometer sideways
- Avoid touching the pan or bone
- Remove chicken at 160–162°F and let it rest
Carryover heat will finish the cooking.
Visual Signs (Backup Only)
If you don’t have a thermometer:
- Juices run clear
- Meat is opaque white
- Center feels firm, not squishy
Thermometers are more reliable—especially for thick breasts.
Should You Cover Chicken Breast When Baking?
Covering chicken breast changes texture and moisture.
- Covered: Softer texture, less browning, more moisture
- Uncovered: Better browning, firmer texture
Many cooks bake uncovered and loosely tent with foil during resting if needed.
How Long to Rest Chicken Breast After Baking
Resting is not optional.
- Rest for 5–10 minutes
- Allows juices to redistribute
- Prevents dryness when slicing
Cutting immediately is one of the most common mistakes.
How to Keep Chicken Breast Juicy in the Oven
Juiciness is about moisture retention, not complicated techniques.
- Light coating of oil
- Season just before baking
- Avoid overcooking
- Rest after baking
Optional: A quick 15-minute salt brine can significantly improve moisture, especially for thick breasts.
Common Mistakes That Make Chicken Breast Dry
Dry chicken usually comes from one of these:
- Overcooking past 165°F
- Cooking uneven thickness
- Skipping resting time
- Baking straight from fridge
- Using too high heat for thick cuts
Fixing even one of these dramatically improves results.
How Long to Cook Frozen Chicken Breast in Oven
Frozen chicken breast can be baked, but it takes longer.
- Add 50% more time
- Bake at 375°F
- Expect 35–45 minutes
For best texture, thaw first whenever possible.
Convection Oven vs Conventional Oven Cooking Time
Convection ovens cook faster.
- Reduce temperature by 25°F
- Or reduce time by 20%
- Watch closely near the end
It can dry chicken faster if not monitored.

Bake vs Roast Chicken Breast (Is There a Difference?)
Technically, baking and roasting are similar.
- Baking: Lower heat, gentler cooking
- Roasting: Higher heat, more browning
For chicken breast, the method matters less than temperature and timing.
Frequently Asked Questions
Is it better to bake chicken at 350 or 400?
400°F is faster and more flavorful, 350°F is more forgiving.
Why is my baked chicken breast rubbery?

Can chicken be slightly pink inside?
Color varies. Temperature matters more than color.
Should I use foil?
Optional. Foil reduces browning but can help retain moisture.

To get it right every time:
- Choose the right temperature
- Adjust for thickness
- Use a thermometer
- Rest before slicing
When you respect those four rules, oven-baked chicken breast becomes reliable, juicy, and stress-free—not a gamble.
Cooking chicken breast in the oven doesn’t need to be complicated.
Once you understand time, temperature, and thickness, you’ll never second-guess dinner again.
