The chicken is the foundation—boneless, skinless breasts ensure even cooking and maximum tenderness. Costco or Sam’s Club offer bulk packs perfect for feeding a crowd. For the BBQ sauce, Stubb’s Original or Sweet Baby Ray’s deliver that ideal smoky-sweet balance. The brioche buns, with their buttery richness, elevate the sandwich from good to exceptional—Whole Foods has excellent options.
No brioche? Potato buns work in a pinch (toast them first). Out of smoked paprika? Regular paprika plus a pinch of liquid smoke mimics the flavor. For a tangier kick, increase the apple cider vinegar by half. The pickles can be swapped for pickled jalapeños if you prefer heat. Always let the chicken rest after grilling—5-10 minutes keeps it juicy.
Store raw chicken in the coldest part of your fridge for up to 2 days. BBQ sauce keeps for 1 month unopened, 1 week once opened. Assemble just before serving to prevent soggy buns. Leftovers? Reheat chicken gently and crisp the buns in a skillet.

Step-by-Step Instructions for Grilled BBQ Chicken Sandwich
Master the technique for juicy, char-kissed chicken with smoky-sweet sauce on buttery buns.
Step 1: Season and Marinate the Chicken
Pound the 1.5 lb Boneless Chicken Breasts to an even ½-inch thickness for consistent cooking. In a bowl, whisk together the 1 tsp Kosher Salt, 0.5 tsp Freshly Ground Black Pepper, 1 tsp Garlic Powder, 1 tsp Smoked Paprika, 1 tbsp Brown Sugar, and 1 tbsp Apple Cider Vinegar with the 2 tbsp Olive Oil to form a paste.
Coat the chicken thoroughly with this mixture, ensuring every surface is covered. Let it marinate for 15-30 minutes at room temperature. This step tenderizes the meat and builds a flavor foundation that pairs perfectly with the smoky BBQ sauce.
Step 2: Grill to Charred Perfection
Preheat your grill to medium-high heat (about 400°F). Clean and oil the grates to prevent sticking. Place the marinated chicken on the grill and cook for 5-6 minutes per side, or until the internal temperature reaches 165°F.
Resist the urge to move the chicken too soon. You want deep grill marks and a slight char for that authentic smoky flavor. The chicken is ready to flip when it releases easily from the grates. Brush the cooked chicken with 1 cup of the 1.5 cups BBQ Sauce during the last 2 minutes of grilling to caramelize the sauce.
Step 3: Toast the Brioche Buns
While the chicken rests, lightly toast the 4 whole Brioche Buns. Spread the 2 tbsp Butter on the cut sides of the buns and place them butter-side down on the grill. Toast for 1-2 minutes until they are golden brown and slightly crisp.
This step adds a rich, buttery flavor and prevents the buns from becoming soggy when assembled. Keep an eye on them to avoid burning—the high sugar content in brioche means they toast quickly.
Step 4: Assemble the Sandwiches
Slice the grilled chicken into strips or leave whole, depending on your preference. Place a piece of Romaine Lettuce on the bottom half of each toasted bun. Top with the grilled chicken, then drizzle with the remaining 0.5 cup BBQ Sauce.
Add the thinly sliced 0.5 whole Red Onion and 0.5 cup Pickles for a tangy crunch that cuts through the richness. Cap with the top bun and press gently to set. Serve immediately while the chicken is hot and the buns are still crisp.
Pro Tips For Making Grilled Bbq Chicken Sandwich
- Pound the Chicken: Use a meat mallet or rolling pin to even out the chicken breasts to ½-inch thickness—this way they cook through without drying out before the outside chars.
- Oil the Grill, Not the Chicken: Dip a paper towel in olive oil and brush it on the grill grates right before cooking; it prevents sticking way better than oiling the meat itself.
- Sauce at the End: I learned this the hard way—brush on the BBQ sauce only in the last 2 minutes of grilling to keep it from burning and turning bitter.
- Toast the Buns: Lightly butter the brioche buns and toast them face-down on the grill for 30 seconds; it adds a crisp layer that holds up to the saucy chicken.
Perfect Pairings for grilled bbq chicken sandwich
Classic Sidekicks
I love serving this with crispy potato wedges—toss 2 lbs Yukon Gold potatoes with 2 tbsp olive oil and 1 tsp smoked paprika, then roast at 425°F for 25-30 minutes. Their earthy flavor complements the smoky chicken perfectly. 🔥
Fresh Contrasts
Balance the richness with a simple slaw—shred 4 cups green cabbage and toss with ¼ cup apple cider vinegar, 1 tbsp brown sugar, and 1 tsp celery seeds. The acidity cuts through the BBQ sauce beautifully.
Beer Pairings
An iced cold lager like Samuel Adams or Modelo Especial refreshes your palate between bites. For craft beer lovers, a citrusy IPA such as Hazy Little Thing adds a hoppy contrast that works wonders. 🍺
Light Alternatives
Swap wedges for a grilled corn salad—toss 3 cups charred corn kernels with ½ cup crumbled cotija, 2 tbsp lime juice, and fresh cilantro. The sweetness and smokiness mirror the chicken’s char.
Sweet Finish
End with peach cobbler—the caramelized fruit echoes the BBQ sauce’s sweetness. Or try grilled pineapple with a sprinkle of cinnamon for a quick, smoky dessert that ties the meal together.
