Alabama white sauce is a tangy, creamy, peppery BBQ sauce born in northern Alabama that will completely change how you think about barbecue. Made with a mayonnaise and apple cider vinegar base and loaded with horseradish, Dijon mustard, and cayenne, this no-cook sauce comes together in just 10 minutes and keeps in the fridge for up to two weeks — making it the ultimate make-ahead condiment for smoked chicken, pulled pork, grilled fish, and so much more.
Medium mixing bowl - Glass or stainless steel works best
Whisk - A balloon whisk makes the job easier; a fork works too
Measuring cups and spoons
Airtight storage container - Mason jars or plastic containers with tight-fitting lids
Rubber spatula - For scraping every last bit into your storage container
Ingredients
2cupsmayonnaise - 480ml; full-fat recommended for best flavor and texture
1/2cupapple cider vinegar - 120ml

2tablespoonsDijon mustard - 30g
1tablespoonWorcestershire sauce - 15ml
2teaspoonsgarlic powder - 6g
1teaspoononion powder - 3g
1teaspoonblack pepper - 2g; freshly ground makes a noticeable difference
1teaspooncayenne pepper - 2g; adjust based on heat preference
1teaspoonkosher salt - 6g
1/2teaspoonpaprika - 1g; adds color and a hint of smokiness
Instructions
Gather all ingredients and equipment on a clean work surface. If using fresh lemons, juice them now and strain out any seeds.
Add the mayonnaise, apple cider vinegar, and lemon juice to your mixing bowl. The liquids may initially appear to separate from the mayo — this is normal.
Stir in the prepared horseradish, Dijon mustard, and Worcestershire sauce — these three ingredients give the sauce its depth and complexity.
Add all dry seasonings at once: garlic powder, onion powder, black pepper, cayenne pepper, salt, and paprika.
Whisk vigorously for about 2 minutes, scraping down the sides and bottom, until completely smooth with no visible lumps or pockets of unmixed mayo.
Taste with a clean spoon and adjust as needed — add more vinegar or lemon juice for tang, more cayenne for heat, or a pinch of salt to balance.
Transfer to an airtight container and refrigerate for at least 2 hours before serving — overnight is even better to let the flavors fully meld.
Notes
Use full-fat mayo: Low-fat or reduced-calorie mayo produces a thinner, less flavorful sauce. Duke's is a top recommendation for its tangy, sugar-free profile.
Room temperature mayo whisks better: Let it sit out for 15 minutes before mixing for a smoother, more emulsified sauce.
Don't over-whisk: Two minutes of vigorous whisking is enough — excessive whisking can thin out the mayo and make the sauce runny.
Make it ahead: The sauce tastes significantly better after chilling overnight as flavors meld together. You can make it up to 2 weeks in advance.
Taste before and after chilling: Flavors intensify in the fridge, so the sauce should taste slightly under-seasoned when first mixed.
Cayenne can vary: Potency differs by brand — start with less if heat-sensitive and add gradually, as you can't take it out once it's in.
Storage: Keep in an airtight container in the refrigerator for up to 2 weeks. Always use a clean spoon to scoop. Do not freeze — mayonnaise-based sauces become grainy when thawed.
Separation is normal: The sauce may separate slightly after sitting; just stir before use and it will come back together perfectly.
Lighter version: Replace half the mayonnaise with Greek yogurt to cut calories and fat, though the texture will be slightly thinner and more tart.
Never heat this sauce: It is meant to be served cold or at room temperature — heating will cause the mayonnaise to break and become unappetizing.
