Perfectly Baked Chicken Breast: How Long at 350°F? Your Guide to Juicy Results

It’s one of the most common kitchen questions: "How long do I bake chicken breast at 350°F (175°C)?" You want it cooked through and safe, but desperately want to avoid that dry, chewy texture that plagues so many baked chicken attempts.

The simple truth? There’s no single magic number. The exact time depends on several factors. However, we can give you reliable estimates and, more importantly, the foolproof method to guarantee perfectly cooked chicken every time.

The Key Factors Influencing Baking Time:

1. Size and Thickness: This is the biggest variable. A thin, small chicken breast (around 5-6 oz) will cook much faster than a thick, large one (8 oz+).
2. Bone-In vs. Boneless: Bone-in chicken breasts generally take longer to cook than boneless ones because the bone insulates the meat.
3. Oven Accuracy: Ovens aren’t always precise. Yours might run hotter or cooler than the set temperature, affecting cook times.
4. Starting Temperature: Fridge-cold chicken will take slightly longer than chicken that has sat at room temperature for 15-20 minutes (though for food safety, don’t leave it out too long).

Forget the Clock, Trust the Thermometer!

While estimates are helpful starting points, the only way to guarantee perfectly cooked, safe, and juicy chicken is by using an instant-read meat thermometer.

The Target Temperature: Chicken breast is safely cooked and ideally juicy when it reaches an internal temperature of 165°F (74°C) in the thickest part, without touching the bone (if applicable).

Estimated Baking Times at 350°F (175°C):

Use these as a guideline, but always start checking the temperature before the minimum time is up:

• Boneless, Skinless Chicken Breasts (Average size, 6-8 oz): Approximately 20-30 minutes.

  • For thinner cutlets or smaller breasts (4-5 oz), start checking around 15-20 minutes.
  • For very large or thick breasts (8 oz+), it might take closer to 30-35 minutes.

• Bone-In, Skin-On Chicken Breasts: Approximately 30-45 minutes, sometimes longer depending on size. The bone adds cooking time.

Step-by-Step Guide to Perfectly Baked Chicken Breast at 350°F:

1. Preheat: Set your oven to 350°F (175°C).
2. Prepare the Chicken: Pat the chicken breasts completely dry with paper towels (this helps with browning and seasoning adherence). Season generously with salt, pepper, and any other desired herbs or spices (garlic powder, onion powder, paprika, Italian seasoning are great choices). You can also lightly coat them in olive oil.
3. Arrange: Place the seasoned chicken breasts in a single layer in a baking dish or on a baking sheet (lining it with parchment paper or foil makes cleanup easier). Ensure there’s some space between the breasts for even cooking.
4. Bake: Place the dish in the preheated oven.
5. Start Checking Temperature: Begin checking the internal temperature with your instant-read thermometer about 5-10 minutes before the estimated minimum cook time (e.g., start checking boneless breasts around the 15-20 minute mark). Insert the thermometer horizontally into the thickest part of the breast, avoiding bone.
6. Cook to Temperature: Continue baking until the thermometer registers 165°F (74°C).
7. REST! (Crucial Step): Once the chicken reaches temperature, remove it from the oven. Tent loosely with foil and let it rest for 5-10 minutes before slicing or serving. This allows the juices to redistribute throughout the meat, resulting in a much juicier and more tender breast. Skipping this step is a common cause of dry chicken!
8. Serve: Slice against the grain and enjoy your perfectly baked chicken!

Tips for Extra Juicy Chicken:

• Don’t Overcrowd: Give the chicken space in the pan for hot air to circulate.
• Consider Pounding: If your chicken breasts are unevenly thick, gently pound the thicker end with a meat mallet (between plastic wrap) to create a more uniform thickness for even cooking.
• Brining (Optional): For guaranteed juiciness, consider a quick brine (soaking in salt water solution) for 30 minutes to an hour before baking. Rinse and pat dry thoroughly before seasoning.

In conclusion, while 20-30 minutes for boneless and 30-45 minutes for bone-in are good starting points for baking chicken breast at 350°F, your best friend is an instant-read thermometer. Cooking to the safe internal temperature of 165°F (74°C) and letting it rest properly will give you perfectly juicy, tender, and delicious results every time.
