Tender juicy Grilled Sweet Cajun Chicken has become a favorite for cookouts and quick weeknight dinners at my house. With just a handful of classic Cajun spices plus a touch of brown sugar for balance this chicken turns out smoky with a punch of sweetness. Whether you pile it onto a salad stuff it into sandwiches or enjoy it right off the grill it is always a crowd-pleaser.
This chicken became my family’s go-to after we craved something bold but still kid-friendly. The simple marinade is now a summer habit and I even use leftovers in wraps for lunches.
Ingredients
- Olive oil: helps the chicken stay moist on the grill and delivers a rich base select extra-virgin if possible for the best flavor
- Cajun spice blend: infuses smoky spicy notes choose one with paprika cayenne garlic and onion for true Cajun flair
- Brown sugar: lends a gentle sweetness that caramelizes on the grill use light brown sugar packed for moisture
- Large chicken breasts: serve as a lean canvas for all those flavors choose breasts that are plump and uniform in size for even cooking
Step-by-Step Instructions
- Make the Marinade:
- Combine olive oil Cajun seasoning and brown sugar in a large zip-top bag or glass container. Mix thoroughly to form a thick seasoning paste that will cover the chicken evenly.
- Prepare the Chicken:
- Lay chicken breasts flat on a chopping board and carefully slice each one in half horizontally so you end up with four even thin cutlets. This helps the marinade penetrate and ensures even quick grilling.
- Marinate the Chicken:
- Add the sliced chicken breasts to the marinade making sure each piece is fully coated. Cover or seal and refrigerate for at least thirty minutes. For the most flavor leave it overnight or up to twenty four hours.
- Heat the Grill:
- Get your grill hot before adding the chicken. Preheating ensures you get those grill marks and caramelization. If using a stovetop pan use medium high heat.
- Grill the Chicken:
- Remove chicken from marinade and let excess drip off. Place the chicken on the grill and cook for three to four minutes per side. Do not move the chicken around while cooking so you get perfect sear lines. Flip once and finish cooking until the interior is no longer pink.

I adore the way the brown sugar caramelizes on the grill turning sticky and almost candied at the edges. One summer we made a double batch for a big family picnic and there was not a single piece left.
Storage Tips
Store leftover grilled chicken in an airtight container in the refrigerator where it stays juicy for up to three days. To freeze marinated but uncooked chicken slip it into a freezer bag making sure it is well coated and freeze up to six months for quick meals later on. Thaw overnight in the fridge before grilling.
Ingredient Substitutions
If Cajun seasoning is too spicy use half the amount and add a little smoked paprika for warmth without as much heat. In a pinch boneless skinless thighs also work well with this marinade and provide a juicier bite.
Serving Suggestions
Slice the chicken and serve over a fresh green salad with corn and avocado. Tuck into warm sandwich rolls with crunchy lettuce and creamy mayo. Toss sliced chicken with warm pasta for a Cajun spin on chicken Alfredo.
