Crispy buttermilk-brined chicken, pickles, soft bun. This high calorie chicken sandwich is the lunch that launched a thousand drive-through wars.
Place chicken thighs in a bowl with buttermilk and 1 teaspoon kosher salt; marinate for at least 1 hour in the refrigerator to ensure maximum tenderness and flavor infusion.
In a large bowl, combine flour, garlic powder, paprika, black pepper, and remaining salt; dredge each chicken thigh thoroughly, pressing to adhere the seasoned flour.
Heat vegetable oil in a deep skillet to 350°F. Carefully add chicken thighs, frying 4-5 minutes per side until deep golden brown and crisp. Maintain oil temperature during frying.
Drain fried chicken on a wire rack for 2-3 minutes to preserve crispiness and avoid sogginess from excess oil; do not cover.
Assemble the sandwich by layering fried chicken on buns, topping with dill pickle slices. Serve immediately for best texture.
