I still remember my first whiff of hickory smoke at a family cookout—it changed how I approach grilling forever. This sandwich brings that smoky char to your table.
Tender grilled thighs meet creamy garlic aioli between soft buns. The secret is high heat and patience for perfect char marks every time.

The chicken thighs are non-negotiable here. Boneless, skinless gives you even cooking and maximum char—Costco has great packs if you’re feeding a crowd. Soak those hickory chips for at least 30 minutes, or they’ll burn up before doing their job. I always keep a bag of Traeger hickory pellets on hand for emergencies (or just because).
Out of Dijon? Whole-grain mustard at half the amount works, but the texture’ll be different. No hickory chips? Apple or pecan wood gives a milder but still delicious smoke. The brioche buns can be swapped for potato rolls (trust me, they’re just as soft). If you’re skipping the aioli, at least brush the buns with garlic butter—don’t leave them dry.
Smoke the chicken fresh—leftovers lose that char magic after 2 days in the fridge. The aioli? Keeps 1 week covered. Assemble sandwiches right before serving, or the buns get soggy. Hickory chips? Store dry in a sealed bag for 6 months (or until you fire up the grill again).

Step-by-Step Instructions for Grilled Chicken Thigh Sandwich
Here’s the method I use to get that perfect smoky char and juicy bite every time.
Step 1: Prepare the Chicken and Soak Wood Chips
Pat the 1.5 lb boneless skinless chicken thighs completely dry with paper towels. This step is crucial for achieving even charring and preventing sticking on the grill. Season them generously with the 1 tsp salt, 0.5 tsp black pepper, and 0.5 tsp smoked paprika, making sure to coat all sides evenly.
Meanwhile, soak the 1 cup hickory wood chips in water for at least 30 minutes. This prevents them from burning too quickly and ensures they’ll produce that beautiful, aromatic smoke we’re after. Drain them just before you’re ready to start grilling.
Step 2: Make the Garlic Aioli
While the chicken rests and the wood chips soak, prepare the aioli. Mince the 4 cloves garlic cloves finely—you want small pieces that will blend smoothly into the sauce. In a small bowl, whisk together the 0.5 cup mayonnaise, 1 tbsp lemon juice, and 1 tbsp Dijon mustard.
Add the minced garlic and stir to combine. The acidity from the lemon juice will mellow the garlic’s sharpness while the Dijon adds a subtle tang. Taste and adjust seasoning if needed, though the chicken will bring its own savory notes to the sandwich.
Step 3: Grill the Chicken to Perfection
Preheat your grill to medium-high heat (about 375-400°F). If using a charcoal grill, bank the coals to one side for indirect heat. Add the soaked 1 cup hickory wood chips directly to the coals or to a smoker box for gas grills. Brush the chicken thighs lightly with the 2 tbsp olive oil to help them develop a beautiful crust.
Grill the chicken for 6-7 minutes per side, or until the internal temperature reaches 165°F and you see distinct char marks. Avoid pressing down on the chicken with your tongs—this squeezes out precious juices. Let the chicken rest for 5 minutes after grilling to allow the juices to redistribute.
Step 4: Toast Buns and Assemble Sandwiches
Lightly toast the 4 whole brioche buns on the grill or in a skillet with a touch of butter. This adds a subtle crunch that contrasts beautifully with the tender chicken. Spread a generous layer of the garlic aioli on both the top and bottom halves of each bun.
Slice the 0.5 whole red onion thinly and arrange the slices on the bottom bun. Add 2 pieces butter lettuce leaves and 2 slices heirloom tomato slices to each sandwich, then top with a grilled chicken thigh. Cap it with the top bun and press gently. The result should be a harmonious blend of smoky, creamy, and fresh flavors in every bite.
Pro Tips For Making Grilled Chicken Thigh Sandwich
- Pound the Thighs: Use a rolling pin or meat mallet to even out the thickness of the boneless thighs to ½ inch—this guarantees they cook through at the same rate without drying out the thin edges.
- Marinate 30 Minutes: Mix the lemon juice, minced garlic, and Dijon mustard with the chicken and let it sit for at least 30 minutes; the acid tenderizes the meat and the flavors actually penetrate.
- Skip the Cold Chicken: Let the thighs sit at room temperature for 15-20 minutes before grilling—I learned this the hard way after serving undercooked centers more times than I’d like to admit.
- Toast the Buns: Lightly butter and toast the buns on the grill for 1-2 minutes while the chicken rests; it adds a crucial crunch that keeps the sandwich from turning soggy under the mayo.
Flavor Customization for This Dish
Spice It Up
Add ½ tsp cayenne pepper to your rub for a subtle kick that doesn’t overpower. I discovered this trick at a local BBQ competition—it enhances the smokiness without adding heat. For real spice lovers, mix 1 tbsp sriracha into the aioli. 🌶️
Herb Infusion
Fresh herbs from my coastal foraging spots elevate this sandwich. Stir 1 tbsp chopped rosemary into the aioli for a piney note. Or add 2 tbsp fresh cilantro to the chicken rub. These small additions make the flavors pop.
Cheese Please
Melt 1 slice pepper jack on each chicken thigh during the last 2 minutes of grilling. The cheese adds creaminess while the jalapeños give a mild heat. Alternatively, crumbled blue cheese on the aioli offers a bold, tangy contrast.
Sweet and Smoky
Brush the chicken with 1 tbsp honey during the final 1 minute of grilling for a sweet glaze. This caramelizes beautifully with the smoke. I also love adding 2 slices crispy bacon to each sandwich for extra depth.
Crunchy Texture
Add ¼ cup pickled jalapeños for tangy crunch. Quick-pickle thin onion slices in ½ cup apple cider vinegar and 1 tsp sugar for 30 minutes before assembling. This cuts through the richness perfectly.
