01 - Pat chicken breasts dry with paper towels and season both sides generously with 1 teaspoon salt and 1/2 teaspoon black pepper.
02 - In a large bowl, whisk together buttermilk, hot sauce, chopped jalapeños, and minced garlic until fully combined.
03 - Submerge seasoned chicken breasts in the marinade, ensuring complete coverage. Cover and refrigerate for at least 1 hour, or overnight for maximum flavor penetration.
04 - In a shallow dish, combine flour, cornmeal, smoked paprika, cayenne pepper, garlic powder, onion powder, salt, and pepper. Mix thoroughly to distribute spices evenly.
05 - Remove chicken from marinade, allowing excess liquid to drip off. Dredge each piece in the breading mixture, pressing firmly to ensure complete adhesion. Transfer coated pieces to a wire rack.
06 - Pour approximately 2 inches of vegetable oil into a deep skillet or Dutch oven. Heat to 350°F, maintaining temperature throughout frying process.
07 - Working in batches to avoid overcrowding, fry chicken breasts for 6–8 minutes per side until golden brown and crispy. Verify doneness with a food thermometer reading 165°F at the thickest part.
08 - Transfer fried chicken to a clean wire rack or paper towels to drain excess oil. Allow to rest for 5 minutes before serving to retain juiciness.
