Ingredients Notes

The beauty of White BBQ Chicken Subs lies in their simple yet flavor-packed ingredients. Let’s break them down so you can get the most out of each bite.

Chicken Breasts: Boneless, skinless chicken breasts work best here. They're easy to grill and slice into juicy, tender pieces. You can also use chicken thighs for a richer flavor.
White BBQ Sauce: This tangy blend of mayonnaise, vinegar, horseradish, and spices is what sets these subs apart. You can make it from scratch (recipe below!) or use a store-bought version if you're short on time.
Sub Rolls: Look for soft, sturdy rolls that can hold up to the saucy filling without falling apart. Toasting them lightly adds a nice crunch.
Pickles: Dill pickles add a tangy crunch that balances the richness of the sauce. Thinly sliced bread-and-butter pickles work well, too, for a sweeter note.
Vegetables: Crisp lettuce and thinly sliced red onions give the sandwich freshness and a satisfying crunch.

You’ll also need basic grilling tools like a grill pan or outdoor grill, a whisk, and a small bowl for the sauce.

How to Make These White BBQ Chicken Subs

Making these White BBQ Chicken Subs is simple and straightforward. Follow these steps for a guaranteed crowd-pleaser.

Prep the Chicken: Start by seasoning your chicken breasts with salt, pepper, and a pinch of smoked paprika. This adds a subtle smoky flavor that pairs beautifully with the tangy sauce.
Grill to Perfection: Heat a grill pan or outdoor grill to medium-high heat. Cook the chicken for about 4-5 minutes per side, or until it reaches an internal temperature of 165°F. Let the chicken rest for a few minutes before slicing it into thin strips.
Make the White BBQ Sauce: While the chicken cooks, whisk together 1 cup mayonnaise, 2 tablespoons apple cider vinegar, 1 tablespoon prepared horseradish, 1 teaspoon Dijon mustard, and a dash of cayenne pepper. Adjust the seasonings to taste—more horseradish for heat, or a pinch of sugar for balance.
Toast the Rolls: Slice your sub rolls in half and toast them lightly under a broiler or on the grill until golden brown. This step helps the bread stand up to the juicy fillings.
Assemble the Subs: Spread a generous layer of the white BBQ sauce on the bottom half of each roll. Layer on the grilled chicken slices, followed by lettuce, thinly sliced red onions, and a handful of pickles. Drizzle more sauce on top, then add the top bun.
Serve Immediately: Serve your subs warm, with extra sauce on the side for dipping.

Storage Options

These White BBQ Chicken Subs are best enjoyed fresh, but you can easily prepare parts of the recipe ahead of time.

Chicken: Grilled chicken can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet or microwave before assembling your subs.
White BBQ Sauce: The sauce can be made up to 5 days in advance and stored in a sealed jar in the fridge. Stir well before using.
Assembled Subs: If you have leftovers, wrap them tightly in foil and store them in the fridge for up to 1 day. Reheat in the oven at 350°F for 10-12 minutes to keep the bread from getting soggy.

Variations and Substitutions

One of the best things about these White BBQ Chicken Subs is how versatile they are. Here are some ways to make them your own:

Spicy Kick: Add sliced jalapeños or a dash of hot sauce to the white BBQ sauce for an extra kick.
Vegetarian Option: Replace the chicken with grilled portobello mushrooms or crispy tofu for a plant-based version.
Cheesy Upgrade: Melt a slice of provolone or pepper jack cheese on top of the chicken before assembling the sandwich.
Bread Alternatives: Swap the sub roll for a ciabatta bun, tortilla wrap, or even lettuce leaves for a low-carb option.
Add Bacon: Crispy bacon strips bring an irresistible smoky crunch that pairs perfectly with the creamy sauce.

Experiment with these ideas, and don’t be afraid to add your own twist. Every bite is guaranteed to be delicious!
