Step 1

In a large bowl, combine the ground chicken, sour cream, breadcrumbs, chives, garlic, salt, black pepper, mustard, and hot sauce (if using). Mix gently to combine well. Divide the mixture into 6 even portions (about 6 ounces each). Pat together into a ball, then press into a patty, about ¾-inch thick. Place the patties on small squares of parchment or waxed paper to make it easier for transferring to the grill.

Step 2

On the stove-top: Heat a large cast-iron skillet over medium-high heat. Add 1 tablespoon vegetable oil and swirl to coat the pan. Remove the patties from the wax paper, place in the skillet, and let cook for 5 minutes. Flip and cook the other side until the internal temperature of the burger reaches 165˚, about 5 more minutes.

Step 3

Alternatively, grill the burgers: Preheat the grill over medium-high heat (400 to 425˚) and oil the grill grates. Remove the patties from the wax paper and place on the grill over direct heat. Cook, with the grill covered, until the internal temperature of the burger reaches 165˚, about 4 to 5 minutes per side.

Step 4

Serve immediately on toasted buns with whatever toppings that you like!
