This Alabama-inspired white BBQ chicken sub delivers a tangy twist on traditional barbecue sandwiches. The creamy, zippy sauce paired with tender seasoned chicken creates a sandwich experience that feels indulgent yet refreshingly different from typical tomato-based BBQ.
I discovered white BBQ sauce during a road trip through Alabama five years ago and immediately knew I needed to create my own version. This sandwich has become our go-to summer meal when we want something satisfying without hours at the grill.
Ingredients
- Boneless chicken breasts or thighs the foundation of our sandwich, either cut works beautifully though thighs offer more natural moisture and flavor
- Olive oil helps seasonings adhere to the chicken and promotes beautiful browning
- Smoked paprika adds a subtle smokiness that mimics hours of barbecuing without the actual smoke
- Mayonnaise forms the creamy base of our Alabama-style white BBQ sauce with the perfect thickness
- Apple cider vinegar provides the signature tang that makes white BBQ sauce so distinctive and craveable
- Prepared horseradish adds a gentle heat and complexity that elevates this beyond a basic mayo sauce
- Sub rolls look for rolls with a slightly crisp exterior and soft interior for the perfect texture contrast
Step-by-Step Instructions
- Prepare the chicken
- Season chicken breasts with the perfect blend of spices. The key is ensuring even thickness by pounding gently with a meat mallet or rolling pin between plastic wrap. This guarantees consistent cooking and tenderness throughout. Apply seasonings liberally on both sides pressing gently to adhere.
- Cook the chicken
- Heat your pan or grill to medium-high before adding the chicken. Allow each side to develop a golden crust before flipping approximately 6 minutes per side. Test for doneness using a meat thermometer aiming for exactly 165°F. Let the chicken rest for 5 minutes before slicing to retain all those flavorful juices.
- Mix the white BBQ sauce
- Combine all sauce ingredients in a bowl ensuring the horseradish and spices are fully incorporated. The sauce should have a pourable yet slightly thick consistency. Taste and adjust seasonings remembering that flavors will develop further as the sauce chills. For best results make this sauce at least 30 minutes before serving.
- Toast the sub rolls
- Apply a thin layer of butter to the cut sides of each roll. Place buttered side down in a skillet over medium heat watching carefully as they turn golden in just 1 to 2 minutes. The contrast between the crispy buttered bread and creamy sauce makes all the difference.
- Assemble your masterpiece
- Layer fresh greens on the bottom half of each toasted roll creating a moisture barrier. Arrange sliced chicken in an overlapping pattern then generously drizzle with the white BBQ sauce. Add optional toppings like tomatoes or pickles based on preference. Serve immediately while the bread is still warm and slightly crisp.

The horseradish in this sauce is truly transformative. When I first experimented with this recipe I was tempted to skip it thinking the flavor might be too strong. That would have been a serious mistake. The horseradish provides that subtle heat that lingers pleasantly without overwhelming setting this sauce apart from anything store-bought.
Make-Ahead Options
The beauty of this recipe lies in its flexibility for busy schedules. The white BBQ sauce actually improves after sitting in the refrigerator for a day as the flavors meld together beautifully. Store it in an airtight container for up to a week. The chicken can be cooked and refrigerated up to two days ahead simply slice it cold and briefly warm in a covered skillet with a tablespoon of water to prevent drying. Assemble sandwiches just before serving to maintain the ideal texture contrast.
Customization Ideas
These subs welcome creative adaptations to suit any preference. For a lighter version use Greek yogurt in place of half the mayonnaise in the sauce. Spice lovers can increase the horseradish or add a full teaspoon of cayenne to the sauce. For a complete meal transform this into a wrap using large flour tortillas or serve open-faced on thick-cut artisan bread topped with melted provolone and broiled until bubbly. The versatile white BBQ sauce also works wonderfully as a dipping sauce for roasted vegetables.
Serving Suggestions
These subs shine when paired with simple sides that complement without competing. Classic potato chips provide the perfect crunchy contrast or try a vinegar-based coleslaw that echoes the tangy notes in the sauce. For a fresher option serve alongside a simple cucumber salad dressed with rice vinegar and dill. If entertaining arrange quartered subs on a platter surrounded by pickle spears various chips and extra sauce in a small bowl for dipping creating an interactive sandwich station.
Recipe FAQs
- → What makes this white BBQ sauce different from regular BBQ sauce?
White BBQ sauce (Alabama-style) is mayonnaise-based rather than tomato-based. It features tangy ingredients like apple cider vinegar, lemon juice, and horseradish, creating a creamy, zesty flavor profile with a bit of heat. Unlike traditional red BBQ sauces that rely on sweetness and smoke, white BBQ sauce emphasizes tanginess and creaminess.
- → Can I prepare any components ahead of time?
Absolutely! The white BBQ sauce can be made up to 5 days ahead and stored in an airtight container in the refrigerator. You can also cook and slice the chicken a day in advance, then reheat it briefly before assembling the subs.
- → What sides pair well with these chicken subs?
These subs pair wonderfully with potato chips, coleslaw, potato salad, grilled corn, or a simple green salad. For a complete meal, you might also consider serving with baked beans or french fries.
- → Can I substitute the chicken with something else?
Yes! This white BBQ sauce works beautifully with grilled or smoked turkey, pork tenderloin, or even firm white fish like cod or halibut. For a vegetarian option, try it with grilled portobello mushrooms or tofu.
- → How spicy is the white BBQ sauce?
The basic sauce is mildly zesty but not spicy. The horseradish provides a gentle kick without overwhelming heat. If you prefer more spice, add the optional cayenne pepper or increase the horseradish. For a milder version, reduce the horseradish or omit the cayenne.
- → Can I grill the chicken on an outdoor grill?
Absolutely! Outdoor grilling adds wonderful smoky flavor. Preheat your grill to medium-high heat and grill the seasoned chicken for about 5-6 minutes per side until it reaches an internal temperature of 165°F (74°C).
