Step 1: Prepare the Chicken: Pat the chicken strips dry with paper towels. This step is crucial for achieving a crispy coating.
Step 2: Create the Breading Mixture: In a shallow dish, whisk together the flour, cornstarch, paprika, garlic powder, onion powder, thyme, cayenne pepper (if using), salt, and pepper. Ensure all ingredients are evenly distributed for consistent flavor.
Step 3: Prepare the Wet Mixture: In a separate shallow dish, combine the buttermilk and beaten egg. Whisk until well combined.
Step 4: Bread the Chicken: Dredge each chicken strip in the flour mixture, ensuring it is fully coated. Dip the floured chicken into the buttermilk mixture, allowing any excess to drip off. Return the chicken to the flour mixture, coating it thoroughly once more. This double coating creates a thicker, crispier crust.
Step 5: Heat the Oil: Pour vegetable oil into a large, heavy-bottomed skillet or deep fryer, filling it to a depth of about 1 inch. Heat the oil over medium-high heat until it reaches a temperature of 325F (163C). Using a deep-fry thermometer is highly recommended for accurate temperature control.
Step 6: Fry the Chicken: Carefully add the breaded chicken strips to the hot oil in a single layer, being careful not to overcrowd the skillet. Overcrowding will lower the oil temperature and result in soggy chicken. Fry the chicken for about 5-7 minutes, turning halfway through, until golden brown and cooked through. The internal temperature of the chicken should reach 165F (74C).
Step 7: Drain and Serve: Remove the fried chicken strips from the skillet using a slotted spoon or tongs and place them on a wire rack lined with paper towels to drain any excess oil. Serve immediately with your favorite dipping sauces.
For a gluten-free option, substitute the all-purpose flour with a gluten-free blend. Consider adding a dash of hot sauce to the buttermilk mixture for extra flavor. Chicken tenderloins can be used instead of chicken breasts for a quicker cooking time.
