Why You’ll Love This Recipe
This is not just any grilled chicken sandwich; it is a culinary revelation. My secret weapon is a unique buttermilk-pickle juice brine that guarantees an incredibly juicy grilled chicken sandwich every time. The pickle juice adds a bright, tangy, and savory depth, creating a flavor profile that perfectly complements the smoky char from the grill. Meanwhile, the buttermilk’s lactic acid gently tenderizes the chicken, locking in moisture and preventing the common problem of dry grilled chicken.
This method ensures consistently juicy and flavorful chicken, taking all the guesswork out of grilling. You will achieve perfectly juicy results, even with lean chicken breast. The zesty and flavorful tang elevates the classic sandwich to a new level. Plus, with quick prep and cook time, this recipe is an easy weeknight meal, ideal for busy schedules. It is also family-friendly and highly customizable, making it a crowd-pleaser with endless topping possibilities.
Ingredients Needed

- 1 1/2 pounds boneless, skinless chicken breasts (about 4 breasts, 6-8 oz each)
- 1 cup buttermilk
- 1/2 cup dill pickle juice
- 1 tablespoon hot sauce (optional)
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon smoked paprika
- 1/2 teaspoon black pepper
- 1/4 teaspoon cayenne pepper (optional, for extra heat)
- 1/2 teaspoon salt
- Brioche buns or sourdough rolls, split and toasted
- For the Special Sauce:
- 1/2 cup mayonnaise
- 2 tablespoons dill pickle relish
- 1 tablespoon ketchup
- 1 teaspoon Dijon mustard
- 1/2 teaspoon garlic powder
- 1/4 teaspoon smoked paprika
- 1 tablespoon dill pickle juice
- For Assembly and Toppings:
- Green leaf lettuce leaves
- Tomato, sliced
- Red onion, thinly sliced
- Dill pickle slices
Ingredient Notes & Substitutions
For the grilled chicken breast, aim for boneless, skinless chicken breasts that are similar in size, about 6 to 8 ounces each. This helps them cook evenly. You can certainly use chicken thighs as well, though they may require a slightly longer grilling time to reach proper doneness. The buttermilk brine is essential here; the buttermilk tenderizes the chicken, and the dill pickle juice infuses it with incredible flavor and moisture. I recommend using natural dill pickle juice for the best taste.
When choosing your bread, brioche buns or sourdough rolls are fantastic choices. Their texture and sturdiness hold up well to the juicy chicken and toppings. If you prefer, whole wheat or gluten-free buns can be great alternatives. The hot sauce in the brine is optional, but it adds a nice kick; Tabasco or Frank’s RedHot are good choices. For the special sauce, the combination of mayonnaise, dill pickle relish, ketchup, Dijon mustard, garlic powder, smoked paprika, and dill pickle juice creates a balanced, creamy, tangy, and savory topping. For a healthy chicken sandwich, consider using light mayonnaise or a yogurt-based alternative for the sauce.
Finally, for the toppings, green leaf lettuce provides a fresh crunch, sliced tomato adds sweetness, thinly sliced red onion offers a nice bite, and extra dill pickle slices deliver that signature tang. Feel free to customize these to your liking.

How to Make Juicy Grilled Chicken Sandwiches
My kitchen thrives on precision and flavor, and this recipe delivers both. Follow these steps for an unforgettable grilled chicken sandwich experience.
Prepare the Chicken
First, prepare your chicken breasts. Place each chicken breast between two pieces of plastic wrap or parchment paper. Using a meat mallet or a heavy, flat-bottomed pan, pound them gently to an even 1/2 to 3/4-inch thickness. This step is crucial for ensuring the chicken cooks evenly and quickly on the grill, preventing any dry spots.
Make the Buttermilk Brine
In a shallow dish or a large, sturdy Ziploc bag, combine the buttermilk, 1/2 cup dill pickle juice, hot sauce (if you are using it), garlic powder, onion powder, smoked paprika, black pepper, cayenne pepper (if you like extra heat), and salt. Whisk these ingredients together very well to create your flavorful buttermilk brine.
Add the pounded chicken breasts to the brine, making sure they are fully submerged. Cover the dish or seal the bag and refrigerate for at least 2 hours. For optimal flavor and tenderness, I recommend brining for up to 8 hours. However, do not exceed 8 hours, as the chicken can become mushy with prolonged brining.
Make the Special Sauce
While the chicken is brining, you can prepare the special sauce. In a small mixing bowl, combine the mayonnaise, dill pickle relish, ketchup, Dijon mustard, 1/2 teaspoon garlic powder, 1/4 teaspoon smoked paprika, and 1 tablespoon dill pickle juice. Stir everything together until the sauce is smooth and creamy. Taste it and adjust any seasonings if you wish. Cover the bowl and refrigerate the sauce until you are ready to assemble your sandwiches.
Prepare the Grill
Preheat your grill to medium-high heat. Aim for a temperature of about 400-450°F (200-230°C). It is important to clean your grill grates thoroughly with a wire brush once they are hot. Then, lightly oil the grates to prevent the chicken from sticking and to help achieve those beautiful golden brown grill marks. A well-preheated and clean grill is essential for successful grilling.
Grill the Chicken
Remove the chicken breasts from the buttermilk brine, allowing any excess liquid to drip off. Discard the remaining brine. Place the chicken breasts carefully onto the preheated, oiled grill grates.
Grill the chicken for 4 to 6 minutes per side. The goal is to get good sear marks on the outside and cook the chicken through to an internal temperature of 165°F (74°C). Always use an instant-read thermometer inserted into the thickest part of the chicken to confirm doneness. This ensures food safety and prevents overcooking, which is the quickest way to dry out your chicken. Cooking time will vary slightly depending on the exact thickness of your chicken and the heat of your charcoal grill or gas grill.
Rest the Chicken
Once the grilled chicken breasts reach 165°F (74°C), transfer them to a clean cutting board or plate. Tent the chicken loosely with aluminum foil and let it rest for 5 to 10 minutes. This resting period is critical; it allows the juices within the chicken to redistribute throughout the meat, keeping it incredibly juicy and tender. Do not skip this step!
Assemble the Sandwiches
While the chicken is resting, lightly toast your brioche buns or sourdough rolls. You can do this on the grill or in a toaster until they are golden brown and slightly crisp. Toasting the bun adds a wonderful textural element and prevents it from becoming soggy from the sauces and juices.
Spread a generous amount of the special sauce on both halves of each toasted bun. Layer with a perfectly grilled chicken breast, fresh green leaf lettuce, a slice of ripe tomato, thinly sliced red onion, and some tangy dill pickle slices. Serve your perfectly juicy grilled chicken sandwich immediately and savor every bite!
Master Your Grill: Tips for Perfect Chicken Every Time
Achieving a perfectly cooked grilled chicken sandwich is an art, but with these techniques, you will master it every time. Preventing dry chicken is the main goal.
Preventing Dry Chicken
Our buttermilk-pickle brine is your ultimate weapon against dry chicken, infusing moisture and flavor deep into the meat. Beyond that, the most important rule is cooking to the correct internal temperature. Use an instant-read thermometer to ensure your chicken reaches precisely 165°F (74°C) and no more. This precision is key to preventing overcooked, dry chicken. Finally, always allow your grilled chicken to rest for 5 to 10 minutes after it comes off the grill. This resting period allows the juices to redistribute, ensuring every bite is succulent.
Grill Setup for Success
Whether you are using a charcoal grill or a gas grill, proper setup is vital. For charcoal grilling, I recommend creating a two-zone fire: one side with direct heat for searing and the other with indirect heat for finishing the cook. For a gas grill, you can achieve a similar effect by lighting burners on one side to medium-high and leaving others off, or set to low. Always preheat your grill thoroughly to the target temperature, around 400-450°F (200-230°C). Before placing the chicken, clean the grill grates with a wire brush and lightly oil them. This prevents sticking and ensures beautiful grill marks.
Achieving Perfect Grill Marks
To get those attractive grill marks, place the chicken on the hot, oiled grates and resist the urge to move it for the first few minutes. This allows the direct heat to sear the surface. For classic crosshatch marks, after the first side has developed distinct lines, rotate the chicken 45 degrees and cook for another 2-3 minutes before flipping. Then repeat on the second side. A clean and hot grill is essential for clear, appealing marks.
Pro Tips & Troubleshooting
Pro Tips
Do not skip the brine. This buttermilk-pickle juice brine is truly the secret weapon for incredibly moist and flavorful chicken. Always pound chicken breasts to an even thickness of 1/2 to 3/4-inch. This ensures they cook evenly and prevents any dry spots. An instant-read thermometer is your best friend. Always use it to ensure the chicken reaches precisely 165°F (74°C) internal temperature; overcooking is the quickest way to dry chicken.
Allow the grilled chicken to rest for 5 to 10 minutes after grilling to help the juices redistribute, ensuring maximum juiciness. A properly toasted bun adds a crucial textural element and prevents it from becoming soggy from the sauces and juices. Finally, take the extra minute to mix up the homemade special sauce. It adds a creamy, tangy, and savory layer that makes a huge difference to the entire sandwich experience.
Common Mistakes to Avoid
Overcooking the chicken is the most common mistake, leading to dry, tough chicken. Always check the internal temperature. Not brining means missing out on significant flavor and tenderness improvements that our unique brine provides. Grilling on a cold or dirty grill leads to sticking, uneven cooking, and poor grill marks. Always preheat and clean thoroughly. Cutting into chicken immediately after grilling allows all the delicious juices to escape; always rest the chicken. Ensure your brine is well-seasoned and consider a light additional seasoning post-brine if you desire extra punch to avoid bland seasoning. Untoasted buns quickly absorb moisture, becoming limp and detracting from the sandwich experience, leading to soggy buns.
Serving & Storage
Serving Ideas
My favorite way to serve these juicy grilled chicken sandwiches is alongside classic side dishes. Think creamy coleslaw, a hearty potato salad, crispy sweet potato fries, or perfectly golden onion rings. For a lighter, healthy meal option, pair your sandwich with a fresh side salad dressed with a tangy vinaigrette. To boost the flavor even more, offer extra dill pickle slices or a dollop of a spicy aioli on the side. A sprinkle of fresh herbs like cilantro or parsley can also brighten the plate. For beverages, refreshing homemade lemonade, a tall glass of iced tea, or a crisp lager are excellent choices.
Storage and Make-Ahead
Cooked grilled chicken breasts can be stored in an airtight container in the refrigerator for up to 3 to 4 days. Always store the special sauce and any fresh toppings separately to maintain their quality. For longer storage, grilled chicken breasts can be frozen for up to 2 to 3 months. Allow them to cool completely, then wrap them tightly in plastic wrap, followed by foil, or place them in a freezer-safe bag. Thaw frozen chicken overnight in the refrigerator before reheating.
This recipe is excellent for make-ahead meal planning. The chicken can be brined for up to 8 hours in advance. The special sauce can be prepared 2 to 3 days ahead of time and stored in the refrigerator. You can also prepare your toppings, such as slicing tomatoes and red onions or washing lettuce, a day in advance for quick assembly. To reheat grilled chicken, gently warm it in a pan with a splash of water or broth, or in the oven at a low temperature, around 300°F (150°C), until warmed through. This prevents it from drying out.
