Mix the base: In a medium-sized bowl, combine mayonnaise and sour cream. Whisk until smooth and creamy — this forms the rich, tangy base of your dip. The smoother it starts, the better it’ll hold the chunky blue cheese later.

Add flavor layers: Stir in garlic powder, onion powder, salt, and pepper. Add the lemon juice (or vinegar) to give it that classic Wingstop-style brightness that cuts through the richness. Mix well to distribute everything evenly.

Fold in the blue cheese: Add the crumbled blue cheese and gently fold it into the mixture. If you prefer a smoother dip, mash some of the crumbles with a spoon. If you like it chunkier (like Wingstop’s signature texture), leave most of them whole.

Adjust consistency: If the dip feels too thick, stir in buttermilk one tablespoon at a time until you reach your desired creaminess. It should be thick enough to cling to wings but still scoop easily with celery or fries.

Chill for flavor: Cover the bowl and refrigerate for at least 30 minutes before serving. This step allows the flavors to blend and the blue cheese to infuse the sauce. The longer it chills, the better it tastes.

Serve and enjoy: Transfer to a small bowl and garnish with chopped chives or parsley for a fresh look. Serve alongside hot chicken wings, fries, or veggie sticks. It’s rich, creamy, and perfectly balanced — just like the dip from Wingstop.
