Crispy, juicy, spicy mayo, pickle on top. The fried chicken sandwich wars happened for a reason — this high calorie dinner is genuinely that good.
Combine buttermilk, 1 tsp paprika, 1 tsp garlic powder, and 1 tsp salt in a large bowl. Add chicken thighs, turning to coat. Cover and refrigerate for at least 1 hour (or overnight for optimal moisture).
In a separate shallow dish, mix flour, cornstarch, 1 tsp paprika, 1 tsp onion powder, 1 tsp salt, and black pepper. Dredge each marinated chicken thigh fully in the flour mixture, pressing to ensure a thick, even coating.
Heat vegetable oil in a heavy-bottomed pot to 350°F (175°C); use a thermometer for precise heat control to avoid soggy breading or burnt outsides.
Fry chicken thighs one or two at a time for 5–6 minutes per side, flipping once for even browning. Lay fried chicken on a wire rack; let rest 3 minutes to allow carryover cooking and keep the crust crisp.
For spicy mayo: In a bowl, combine mayonnaise and hot sauce until smooth. Toast buns lightly, then assemble with lettuce, fried chicken, spicy mayo, and dill pickle slices. Serve immediately for best texture.
