This Southern-style sandwich features grilled chicken breasts seasoned with smoky paprika and garlic, then chopped and coated in Alabama's famous white BBQ sauce—a creamy, tangy blend of mayonnaise, vinegar, horseradish, and mustard. Piled high on toasted buns with crisp coleslaw and pickles, it delivers the perfect balance of smoky, tangy, and creamy flavors in every bite.
The first time I encountered white BBQ sauce, I stared at the bowl with genuine suspicion. Mayo and vinegar on grilled chicken? Then I took that first bite and suddenly everything I thought I knew about barbecue turned upside down. The tangy creaminess cuts through the smoky chicken in ways red sauce never could. Now I keep a jar of this Alabama-style sauce in my fridge year round.
Last summer I made these for a backyard cookout and watched my skeptical cousin go back for thirds. The sound of chopping chicken on a cutting board has become one of my favorite kitchen noises. Theres something so satisfying about building a sandwich that tall and watching everyone try to take that first enormous bite. Friends now specifically request the white sauce sandwiches whenever we fire up the grill.
Ingredients
- 4 boneless skinless chicken breasts: These grill up beautifully and stay juicy when you dont overcook them

These sandwiches have become my go to for feeding a crowd because theyre just so satisfying to eat. Watching someone discover that white sauce for the first time never gets old. Something about the combination of cool creamy sauce, warm smoky chicken, and crisp vegetables hits every single craving.
Making It Your Own
Sometimes I swap in chicken thighs when I want something even more indulgent and forgiving on the grill. The extra fat means you practically have to try to dry them out. Wood chips on the grill take this to a whole new level if you have the time to set it up.
Sauce Secrets
This white BBQ sauce keeps beautifully in the fridge for up to two weeks, which is dangerous because youll want to put it on everything. Ive started using it as a dip for roasted veggies and honestly its changed my lunch game. The horseradish is the ingredient that makes people ask whats in this.
Perfect Pairings
Cold sweet tea is the classic Southern choice but a crisp lager cuts through the richness beautifully too. I like serving these with extra pickles on the side because the vinegary crunch balances everything.
- Make extra sauce and use it the next day on a grilled chicken salad
- Toast your buns with a little butter for extra richness and structure
- Keep the coleslaw on the side until youre ready to eat so nothing gets soggy
Theres something joyfully messy about eating one of these sandwiches with sauce running down your arms and coleslaw falling everywhere. It reminds me that the best food experiences are the ones you cant eat neatly.
Recipe FAQs
- → What makes Alabama white BBQ sauce different?
-
Alabama white BBQ sauce is a mayonnaise-based sauce unlike traditional tomato-based BBQ sauces. It features vinegar, horseradish, mustard, and spices for a creamy, tangy flavor that pairs perfectly with grilled chicken.
- → Can I make the white sauce ahead of time?
-
Yes, the Alabama white BBQ sauce actually develops better flavor when made 1-2 days ahead. Store it in an airtight container in the refrigerator and give it a good stir before using.
- → What's the best way to chop the chicken?
-
Let the grilled chicken rest for 5 minutes after cooking, then use a sharp knife to cut it into bite-sized pieces about ½-inch in size. This helps the chicken absorb the sauce while staying tender.
- → Can I use chicken thighs instead of breasts?
-
Absolutely. Boneless, skinless chicken thighs are juicier and more forgiving than breasts. Grill them until they reach 165°F internally, then chop and sauce them the same way.
- → What sides pair well with this sandwich?
-
Classic Southern sides like potato salad, baked beans, or sweet potato fries complement this sandwich perfectly. For a lighter option, serve with a simple green salad or corn on the cob.
