My secrets to the JUICIEST baked chicken breasts?
- The magic seasoning
- High heat
Magic Cajun Seasoning
The flavor in these Cajun Chicken Breasts lies in the BEST Cajun Spice Mix! Simple to throw together with ingredients you probably have in your cupboard, it adds fantastic flavor.
The secret ingredient in this Cajun Seasoning is brown sugar. The brown sugar caramelizes while it’s baking, sealing in the juices and giving the chicken its beautiful crust and caramelized edges.
Don’t worry, it won’t make the chicken very sweet. It just adds the perfect balance to the mildly spicy flavors. Just a spoonful goes a long way.

The Secret to super JUICY chicken breasts is High Heat
Baking the chicken breasts at a high temperature (425-450° F) seals in the juices and creates a beautiful golden crust. Turning on the broiler in the last few minutes gives those beautiful caramelized edges – my favorite part!
Cooking it hot and fast is what makes it so juicy with those crispy, caramelized edges.
I highly recommend using an instant meat thermometer. It’s a small investment for perfectly cooked chicken every time.
How Long To Bake Chicken Breast
The key to perfectly baked chicken breasts is not overbaking them. Bake them until the internal temperature reaches 165°F. This should take about 15-18 minutes depending on the size/weight of the breasts.

To brine or not to brine
I don’t usually brine chicken breasts before baking them. In fact, when testing for this recipe, I brined half of the breasts. By the time they were done baking, I had forgotten which where brined and which weren’t. It was difficult to tell the difference between the two.
If you would like to brine the chicken, put 1 quart of cool water into a bowl. Stir in ¼ cup of salt. Add the chicken breasts and let them sit in the salted water for at least 15 minutes on the counter or in the refrigerator for up to 6 hours.
When you’re ready to cook, remove them from the brine and pat them off with a paper towel. Use a little less salt in the seasoning mix.
How to make Oven Baked Cajun Chicken Breasts
Prep the chicken breasts – use a meat mallet or rolling pin, hit the chicken breasts so that they are about 1 ½ cm thick at the thickest end. This ensures even cooking.

Rub – rub in the Cajun seasoning, brown sugar, and oil. Add salt to taste if your Cajun Seasoning doesn’t contain salt.

Bake – in a 450° F oven until the internal temperature reaches 165°F on an instant meat thermometer. This should take about 15-18 minutes depending on the size/weight of the breasts. For caramelized edges and crispy bits, turn on the broiler for the last few minutes of baking.
Rest – Let the chicken rest for 5-10 minutes before cutting into it. This lets all those natural juices recirculate throughout the meat.

Grilled Cajun Chicken Breasts
This Cajun Chicken Breasts recipe is also fabulous on the grill. Simply rub the chicken breasts in the spice mix, brown sugar, oil, and salt to taste, and grill until the internal temperature reaches 165° F.

This chicken is packed with flavor. I love your technique of cooking these at a really high heat! I must admit, I don't usually cook chicken in the oven because it turns out so dry. I can't wait to give these a try.

Please can you tell me if the 450f is for a conventional oven or a fan oven?
Thank you
Hi Katie! I bake mine in a conventional oven with some browning under the broiler at the end. If you did try the fan oven, you might not need the broiler at the end. Thanks so much!
This was absolutely delicious cooked mine with red pepper and onions and garlic. Will make again. My husband just loved this dish
So happy you liked it, Judy! Thanks so much!
