Irresistible Blackened Chicken Sandwich

Here is my favorite blackened chicken sandwich recipe, with tender brined chicken breasts coated in smoky Cajun spices, topped with sautéed peppers and onions, melted pepper jack cheese, and a kick of sriracha mayo on toasted club rolls.

This sandwich has become our go-to weeknight dinner when we’re craving something with a little heat and lots of flavor. My kids love building their own at the table, and I love that it comes together in about 30 minutes. Perfect for those busy evenings when takeout just won’t cut it.

What Kind of Chicken Should I Use?

For this blackened chicken sandwich, you’ll want to use boneless, skinless chicken breasts that are about 8 ounces each. If your chicken breasts are on the thicker side (more than an inch thick), consider pounding them to an even thickness so they cook uniformly and don’t dry out. You can also use chicken cutlets if that’s what you have on hand – they’re already thin and will cook even faster. Fresh or frozen chicken works fine here, just make sure frozen breasts are completely thawed before you start the brining process.

Options for Substitutions

This sandwich is pretty forgiving when it comes to swapping ingredients:

• Chicken breasts: Chicken thighs work great here too and stay juicier during cooking. You can also use turkey cutlets if you prefer, just adjust the cooking time since they’re usually thinner.
• Pepper jack cheese: Not a fan of spicy cheese? Try regular Monterey Jack, provolone, or sharp cheddar instead. Swiss also works if you want something milder.
• Red bell pepper: Yellow or orange bell peppers are just as good. Green peppers work too, though they’ll add a slightly more bitter taste.
• Club rolls: Brioche buns, ciabatta rolls, or even Kaiser rolls make excellent substitutes. Just pick something sturdy enough to hold up to the toppings.
• Sriracha mayonnaise: Mix regular mayo with hot sauce, chipotle sauce, or even a bit of buffalo sauce for a similar kick. Or keep it simple with plain mayo if you’re watching the heat level.
• Cayenne pepper: If you want less heat, cut the cayenne in half or leave it out completely. The other spices will still give you plenty of flavor.
• Green leaf lettuce: Romaine, butter lettuce, or even arugula all work fine here. Use whatever crisp greens you have on hand.

Watch Out for These Mistakes While Cooking

The biggest mistake when making blackened chicken is cranking up the heat too high, which burns the spices before the chicken cooks through – medium-high heat gives you that dark crust without turning everything bitter. Don’t skip the brining step even though it seems like extra work, as those 30 minutes in the salt-sugar water keep your chicken from drying out on the grill. Make sure to pat the chicken completely dry after brining and before adding the oil and spices, otherwise the seasoning won’t stick properly and you’ll end up with uneven flavor. Finally, resist the urge to press down on the chicken while it’s grilling – this squeezes out all those juices you worked hard to keep in, leaving you with dry, tough meat instead of a juicy sandwich.

What to Serve With Blackened Chicken Sandwich?

This spicy sandwich pairs perfectly with crispy sweet potato fries or regular fries – something about the cool, creamy sriracha mayo and hot fries just works. If you want to keep things on the lighter side, a simple coleslaw helps balance out the heat from the blackened seasoning and adds a nice crunch. Potato salad or pasta salad are also great options if you’re feeding a crowd at a backyard cookout. For something easy, just grab some kettle-cooked chips and pickle spears to round out the plate.

Storage Instructions

Store: I like to keep the components separate if I’m meal prepping these sandwiches. Store the cooked chicken in an airtight container in the fridge for up to 4 days, and keep the peppers and onions in their own container. The assembled sandwiches can get a bit soggy, so it’s best to build them fresh when you’re ready to eat.

Freeze: The blackened chicken freezes really well on its own. Let it cool completely, then wrap each piece individually in plastic wrap and store in a freezer bag for up to 3 months. I don’t recommend freezing the assembled sandwiches or the veggies, as they won’t hold up as nicely.

Serve: If you’ve got leftover chicken, you can enjoy it cold sliced over a salad, or warm it up in a skillet over medium heat for a few minutes until heated through. Thaw frozen chicken in the fridge overnight before reheating for the best results.

Ingredients

For the brine:

• 2 chicken breasts (I like using Perdue for consistent size and quality)
• 32 fl oz ice water
• 2.5 tbsp salt (I use Morton kosher salt for better dissolving)
• 2.5 tbsp sugar

For the spice rub:

• 1.25 tsp paprika
• 0.75 tsp garlic powder
• 0.75 tsp onion powder
• 0.75 tsp thyme
• 0.5 tsp oregano
• 0.5 tsp cumin
• 0.5 tsp salt
• 0.5 tsp black pepper
• 0.25 tsp cayenne pepper
• 0.25 tsp brown sugar

For the sandwich and grill:

• 2.5 tbsp olive oil (I prefer Bertolli extra virgin for a balanced flavor profile)
• 1 red bell pepper (seeded and sliced into 1/4-inch strips)
• 1 red onion (sliced into thin 1/8-inch rings)
• 4 slices pepper jack cheese
• green leaf lettuce
• sriracha mayonnaise (I use Hellmann’s for the creamiest base)
• 4 club rolls (split and toasted until golden brown)

Step 1: Prepare the Brine and Brine the Chicken

• 2 chicken breasts, cut in half
• 32 fl oz ice water
• 2.5 tbsp salt
• 2.5 tbsp sugar

In a bowl, whisk together the ice water, 2.5 tablespoons salt, and 2.5 tablespoons sugar until fully dissolved.

This brine will keep the chicken moist and add flavor from the inside out.

Cut the chicken breasts in half horizontally to create thinner, more evenly-cooked pieces, then submerge them completely in the brine.

Let them sit for 30 minutes at room temperature—this brining time is crucial for tender, juicy chicken.

Step 2: Mix the Blackening Spice Blend

• 1.25 tsp paprika
• 0.75 tsp garlic powder
• 0.75 tsp onion powder
• 0.75 tsp thyme
• 0.5 tsp oregano
• 0.5 tsp cumin
• 0.5 tsp salt
• 0.5 tsp black pepper
• 0.25 tsp cayenne pepper
• 0.25 tsp brown sugar

While the chicken brines, combine all the dry spices in a small bowl: paprika, garlic powder, onion powder, thyme, oregano, cumin, 0.5 teaspoon salt, black pepper, cayenne pepper, and brown sugar.

Whisk them together thoroughly to ensure even distribution.

I like to make this spice blend ahead of time so it’s ready the moment the chicken finishes brining—it saves precious time when you’re ready to cook.

Step 3: Prepare the Vegetables for Grilling

• 1 red bell pepper, seeded and sliced
• 1 red onion, sliced
• olive oil
• salt and pepper to taste
• green leaf lettuce
• 4 club rolls

Seed and slice the red bell pepper into 1/4-inch strips.

Slice the red onion into thin 1/8-inch rings and place them in a small bowl.

Drizzle the onions with a bit of olive oil and season lightly with salt and pepper—this helps them caramelize evenly on the grill.

Have the lettuce washed and ready for assembly, and split and set aside the club rolls for toasting later.

Step 4: Season the Chicken and Prepare the Grill

• brined chicken from Step 1, patted dry
• 2.5 tbsp olive oil
• blackening spice blend from Step 2

Remove the brined chicken from the liquid and pat it completely dry with paper towels—this is essential for achieving a proper blackened crust.

Coat each piece lightly with 2.5 tablespoons olive oil, then generously coat both sides with the spice blend from Step 2, pressing it gently so it adheres well.

Preheat your grill to medium-high heat for about 5 minutes until it’s hot and the grates are clean.

I prefer to oil and season the chicken right before grilling so the spices don’t absorb moisture and lose their punch.

Step 5: Grill the Vegetables and Chicken Together

• seasoned chicken from Step 4
• prepared peppers and onions from Step 3
• 4 slices pepper jack cheese

Place the seasoned peppers and onions from Step 3 directly on the hot grill grates.

Let them cook for 5-8 minutes, stirring occasionally, until they’re charred and softened.

Once the vegetables are nearly done, place the spiced chicken pieces on the grill alongside them.

Cook the chicken for 3-5 minutes until the bottom is deeply blackened, then carefully flip each piece.

Immediately top each piece with a slice of pepper jack cheese and cook for another 3-5 minutes until the chicken is cooked through and the cheese is melted.

Step 6: Toast the Rolls and Prepare the Mayonnaise

• 4 club rolls, split
• sriracha mayonnaise

Remove the chicken from the grill and let it rest for 3 minutes—this allows the juices to redistribute, keeping the meat tender and moist.

While the chicken rests, place the split club rolls on the grill cut-side down for about 1-2 minutes until they’re lightly golden and toasted.

Spread a generous amount of sriracha mayonnaise on both sides of each toasted roll, preparing them for assembly.

Step 7: Assemble and Serve the Sandwiches

• rested chicken from Step 6 with melted cheese
• grilled vegetables from Step 5
• green leaf lettuce
• toasted rolls with sriracha mayonnaise from Step 6

On each prepared roll, layer a piece of the rested chicken with melted cheese, followed by the charred peppers and onions from Step 5, and finish with a handful of fresh green leaf lettuce.

Close the sandwich with the top half of the roll and serve immediately while everything is still warm.

The combination of the smoky blackened chicken, creamy sriracha mayo, charred vegetables, and cool crisp lettuce creates a perfectly balanced sandwich.
