This is the closest copycat to Chick-fil-A's new Jalapeño Ranch Club you'll find at home. Crispy pressure-fried chicken on a buttery ranch bun with pickled jalapeños, pepper jack, and caramelized onion candied bacon — plus a homemade jalapeño ranch sauce that honestly rivals the real thing.
Pound chicken breasts to an even ½-inch thickness for uniform cooking. Marinate in a mixture of ½ cup buttermilk, 1 tablespoon pickle juice, and 1 beaten egg for at least 30 minutes. (Copycat tip: Buttermilk brine makes the chicken tender and juicy, just like Chick-fil-A.)
Prepare the candied bacon: Rub bacon strips with 2 tbsp brown sugar and ½ tsp onion powder, bake on a rack at 375°F for 15–18 minutes until crispy and caramelized. Let cool on a rack for best texture.
Mix the dredge: Combine all-purpose flour, powdered sugar, 1½ tsp salt, black pepper, MSG (optional), paprika, and garlic powder. Dredge marinated chicken thoroughly, pressing to form a cohesive, lacy crust. (Copycat tip: Powdered sugar in flour gives you Chick-fil-A’s signature thin, golden crust.)
Fry chicken breasts in peanut oil preheated to 340–350°F, ideally pressure-frying or deep-frying for 4–5 minutes per side, until internal temp reaches 165°F and crust is deep golden. Rest on rack. (Copycat tip: Only refined peanut oil replicates original flavor.)
Toast brioche buns until just golden. For the jalapeño ranch, whisk together mayonnaise, ranch dressing, jalapeño brine, and a pinch of garlic powder. (Copycat tip: Jalapeño brine punches up the authentic Chick-fil-A ranch tang.)
Assembly: On the bottom bun, spread jalapeño ranch. Add lettuce, tomato, pickled jalapeños, and hot fried chicken. Place pepper jack slice over chicken so it softens from heat. Top with candied bacon, drizzle more sauce if desired, crown with top bun, and serve immediately.
