If you like spicy Buffalo wings, then you’ll love these Buffalo-style chicken burgers.
In a small saucepan, stir together 4 tablespoons of the hot sauce and the butter, and heat over medium until combined, stirring occasionally. Reserve about half of the sauce for serving.
In a large bowl, combine the chicken, carrot, scallions, garlic, salt, pepper, and remaining 2 tablespoons of hot sauce. Form into 4 patties. Heat about a tablespoon of butter over medium-high in a nonstick skillet. Cook the burgers until browned and cooked through on one side, about 3 minutes. Brush the top of the burger with the hot sauce mixture. Flip the burgers and cook through, another 3 minutes, brushing with the hot sauce mixture occasionally.
To serve, brush the burgers with the reserved hot sauce mixture. Spread the sandwich buns with the buttermilk blue cheese sauce, and layer with lettuce, celery leaves, and the chicken burgers.
