This Grilled Sweet Cajun Chicken recipe fills any summer barbecue with bold smoky flavors and just the right touch of sweetness. I love making it when I want something simple yet impressive for a weeknight dinner or when friends come by unexpectedly. The marinade does all the heavy lifting while you get to enjoy tender juicy chicken with hardly any effort.
I first discovered this marinade when I wanted to jazz up plain chicken breast for my kids. Now they ask for it whenever the grill comes out and even like leftovers tossed with pasta the next day.
Ingredients
- Olive oil: provides richness and keeps the chicken juicy during grilling. Choose a quality extra virgin olive oil for the best flavor
- Cajun spice blend: adds robust smokiness warmth and a hint of spice. Look for a blend with fresh paprika garlic onion and thyme. If your spice mix is unsalted add a pinch of salt for balance
- Brown sugar: brings sweetness that caramelizes on the grill for irresistible flavor. Opt for dark brown sugar if you want more molasses notes
- Large chicken breasts: stay moist when marinated and sliced properly. Use fresh organic chicken when possible for tenderness
Step-by-Step Instructions
- Marinate the Chicken:
- In a medium bowl or zip lock bag mix olive oil cajun seasoning and brown sugar thoroughly until a loose paste forms. Squish it around with your hands or use a spoon for even blending
- Slice the Chicken:
- Lay chicken breasts flat on a clean board. With a sharp knife held parallel to the board carefully slice each breast in half so you get two thinner pieces per breast. This helps the chicken cook through quickly and stay juicy
- Soak and Set:
- Add the chicken to the marinade ensuring each piece is well coated. Cover and refrigerate for at least thirty minutes but marinating twelve to twenty-four hours gives the deepest flavor. You can freeze the chicken at this stage if making ahead
- Heat the Grill:
- Preheat your outdoor grill to high or set a frying pan over medium high heat. Let it get nice and hot before adding the chicken for a good sear
- Grill the Chicken:
- Remove chicken from marinade letting excess drip off. Place on hot grill and cook for three to four minutes until golden brown on one side. Flip and cook the other side for another three to four minutes until the thickest part is fully cooked with clear juices

My favorite part of this recipe is the way brown sugar caramelizes on the grill. Those dark sweet bits are always the first thing my kids pick off their plates. We once made this for a Sunday picnic and ended up eating right off the grill with our fingers because nobody could wait for plates.
Storage Tips
Store leftover chicken in an airtight container in the refrigerator for up to four days. To freeze lay cooked or marinated chicken flat in a zip lock bag pressing out the air. Thaw overnight in the fridge before reheating on a skillet or grill for the best texture.
Ingredient Substitutions
If you do not have cajun spice blend use a mix of smoked paprika garlic powder onion powder dried thyme and a dash of cayenne. Chicken thighs can be swapped for breasts and add salt if your spice blend is unsalted.

Serving Suggestions
Serve with grilled corn lime wedges and a simple green salad for a light summer meal. Slice leftovers for wraps chop into salads or toss with warm pasta and extra vegetables for a quick dinner.
Cajun Roots
Cajun spice blends come from Louisiana where bold smoky and spicy flavors unite in many dishes. The sweetness in this recipe is inspired by the Southern tradition of combining heat and sugar for grilled meats.
