How Long to Bake Chicken Breast

Bake boneless chicken breasts at 400°F (200°C) for 18 to 22 minutes, or at 350°F (175°C) for 25 to 30 minutes, until the thickest part reads 165°F (74°C) on a thermometer.

How Long to Bake Chicken Breast by Oven Temperature

For an average boneless, skinless chicken breast weighing 6 to 8 ounces and about 1 inch thick, the bake time ranges from about 15 minutes at 425°F (220°C) to about 30 minutes at 350°F (175°C). Hotter ovens cook faster and brown the outside more, while lower temperatures are gentler and a little more forgiving if you get distracted. The table below gives typical ranges for boneless breasts placed on a sheet pan on the middle rack.

Oven temperature	Boneless breast (6–8 oz)	Best for
350°F (175°C)	25–30 min	Gentle, even cooking; baking with sauces
375°F (190°C)	20–25 min	All-purpose middle ground
400°F (200°C)	18–22 min	Juicy meat with light browning
425°F (220°C)	15–20 min	Fast weeknight cooking, more color

Treat these numbers as a starting point rather than a promise. Start checking with a thermometer about 3 minutes before the low end of the range, especially with a convection oven, which usually runs 10 to 15 percent faster than a conventional bake setting. USDA’s own roasting chart lists 20 to 30 minutes at 350°F for a smaller 4-ounce boneless breast half, so large supermarket breasts will often land at the upper end of each range.

How Long to Bake Chicken Breast at 400°F

At 400°F (200°C), most boneless breasts are done in 18 to 22 minutes. This is the temperature many cooks settle on because it is hot enough to set a lightly golden surface before the center dries out, yet not so hot that seasoning on the outside burns. Thin cutlets need as little as 10 to 12 minutes at this temperature.

How Long to Bake Chicken Breast at 350°F

At 350°F (175°C), plan on 25 to 30 minutes for a boneless breast, and up to 35 minutes for a very large one over 10 ounces. The lower heat produces less browning, which makes it a good choice when the chicken is baked under a sauce, in a casserole dish, or covered with foil.

How Thickness Changes the Bake Time

Thickness matters more than weight, because heat has to travel from the surface to the center. A breast that is 1½ inches at its thickest point can take nearly three times as long as a ½-inch cutlet. These cards show typical times for boneless breasts at 400°F (200°C).

Most chicken breasts are teardrop shaped, thick at one end and thin at the other. To keep the thin end from drying out while the thick end catches up, pound the breast to an even ¾ inch between two sheets of plastic wrap, or slice a large breast horizontally into two thinner cutlets. Even thickness gives you an even bake and a more predictable time.

Bone-In vs. Boneless Chicken Breast

Bone-in, skin-on chicken breasts, sometimes sold as split breasts, take roughly twice as long as boneless ones. At 400°F (200°C), a bone-in breast of 10 to 12 ounces usually needs 35 to 45 minutes, and at 350°F (175°C) it needs about 45 to 60 minutes. The bone slows heat movement into the meat closest to it, so that area is the last to reach a safe temperature.

Cut	350°F (175°C)	400°F (200°C)
Boneless, skinless (6–8 oz)	25–30 min	18–22 min
Bone-in, skin-on (10–12 oz)	45–60 min	35–45 min

The trade-off is flavor and moisture. The skin bastes the meat as it renders and turns crisp at higher temperatures, and the bone helps the breast hold its juices. When checking a bone-in breast, insert the thermometer into the thickest part of the meat without touching the bone, since bone conducts heat differently and can give a misleading reading.

How Long to Bake Frozen Chicken Breast

You can bake chicken breast straight from the freezer. USDA says frozen chicken can be cooked in the oven or on the stove without thawing, but it takes about 50 percent longer than thawed chicken. In practice, a frozen boneless breast that would take 20 minutes at 400°F (200°C) needs about 30 to 35 minutes.

Separate frozen breasts before baking so heat can reach every side, and rinse off any surface ice so the seasoning sticks. Brush with oil, season, and bake on a lined sheet pan. Frozen chicken tends to release more liquid, so the surface will brown less. USDA advises against cooking frozen chicken in a slow cooker or microwave without thawing first, because the meat can sit too long at unsafe temperatures.

How to Bake Chicken Breast Step by Step

This method works at any of the temperatures above. It uses 400°F (200°C) as the default because it balances speed, moisture and browning for the typical boneless breast.

1. Heat the oven to 400°F. Set a rack in the middle position and line a rimmed baking sheet with parchment or foil for easy cleanup.
2. Even out the thickness. Pound thick breasts to about ¾ inch, or slice very large ones in half horizontally.
3. Dry and season the chicken. Pat the breasts dry with paper towels, brush both sides with oil, and season generously with salt, pepper and any spices you like.
4. Arrange with space between pieces. Leave at least an inch around each breast so hot air can circulate and the chicken roasts rather than steams.
5. Bake for 18 to 22 minutes. Begin checking at about 15 minutes for smaller or thinner breasts.
6. Check the temperature. Insert an instant-read thermometer horizontally into the thickest part. The chicken is done at 165°F.
7. Rest before slicing. Move the chicken to a cutting board and let it rest for 5 minutes.

How to Tell When Baked Chicken Breast Is Done

The only reliable test is internal temperature: chicken breast is safely cooked when the thickest part reaches 165°F (74°C). USDA notes that color is not a dependable sign of doneness, since cooked chicken can look slightly pink near the bone and undercooked chicken can look white. Clear juices and firm texture are helpful hints, but they do not confirm safety on their own.

For the most accurate reading, slide the thermometer probe in from the side so the tip sits in the center of the thickest section. A probe pushed straight down from the top can easily go through to the pan and read the hotter bottom surface instead.

Why Resting Chicken Breast Matters

Resting baked chicken breast for 5 minutes before cutting helps it stay juicy. While the chicken bakes, moisture is pushed toward the center; a short rest lets those juices redistribute so less of them run out onto the board when you slice. The internal temperature also climbs by a few degrees during the rest, a process known as carryover cooking.

Common Mistakes That Dry Out Baked Chicken

Most dry chicken breast is simply overcooked chicken breast. Because a lean breast has very little fat, a few extra minutes past 165°F (74°C) makes a noticeable difference in texture. These are the habits most likely to cause trouble.

• Baking breasts of very different sizes on the same pan and pulling them all at once.
• Skipping the thermometer and cutting into the chicken to check, which lets juice escape.
• Crowding the pan so the chicken steams in its own liquid instead of roasting.
• Leaving the thin end of an uneven breast exposed while the thick end finishes.
• Slicing immediately out of the oven without a short rest.

A quick brine also helps. Soaking breasts for 30 minutes to 2 hours in the refrigerator in a solution of about 1 tablespoon of salt per 4 cups of water seasons the meat throughout and helps it retain moisture during baking. Pat brined chicken dry and season it lightly, since it already contains salt.

How Long Baked Chicken Breast Lasts in the Fridge

Cooked chicken breast keeps for 3 to 4 days in the refrigerator at 40°F (4°C) or below, according to USDA. Refrigerate leftovers within 2 hours of baking, or within 1 hour if the room is above 90°F, and store them in shallow airtight containers so they cool quickly.

For freezing, slice or shred the cooled chicken, pack it into freezer bags with the air pressed out, and label the bag with the date. Thaw frozen cooked chicken in the refrigerator overnight, then reheat it covered in a 350°F oven or in a skillet with a splash of broth until it is hot all the way through.

Frequently Asked Questions

These are short answers to the questions people most often ask about how long to cook chicken breast in the oven.

How long do you bake chicken breast at 375°F?

Bake boneless chicken breast at 375°F (190°C) for 20 to 25 minutes, and bone-in breasts for about 40 to 50 minutes, until the thickest part reaches 165°F.

How long do you bake chicken breast at 425°F?

At 425°F (220°C), boneless breasts take about 15 to 20 minutes. Thin cutlets can be ready in as little as 10 minutes, so start checking early.

Should I cover chicken breast when baking?

Covering is not necessary at 375°F or above, and uncovered chicken browns better. At 350°F, or when baking with a sauce, a loose foil cover can help keep the surface from drying out.

Do I need to flip chicken breast in the oven?

No. Hot air cooks the chicken from all sides, so flipping is optional. Turning it once halfway through can give slightly more even color on both sides.

Is it better to bake chicken breast at 350°F or 400°F?

Both work. 400°F is faster and gives better browning, while 350°F cooks more gently and suits casseroles and sauced dishes. The safe endpoint is the same: 165°F in the thickest part.
