Crispy Buttermilk Fried Chicken Sandwich with Garlic Herb Mayo

This buttermilk fried chicken sandwich delivers that loud, shattering crunch with every bite. Chicken breasts are pounded thin, soaked in seasoned buttermilk, and dredged in flour to create a craggy, extra-crispy crust.

Toasted brioche buns, creamy garlic herb mayo, tangy pickles, and crisp lettuce balance the richness. It's a satisfying dinner that feels like a special treat, yet comes together in under an hour.

Forget dry, bland chicken sandwiches. This recipe focuses on technique: pounding the chicken to an even thickness, soaking it in buttermilk to tenderize, and pressing the flour coating to create those craggy, crunchy bits.

The result is a juicy, flavorful cutlet with a crust that shatters when you bite. Toasted brioche adds sweetness, while the garlic herb mayo and pickles cut through the richness. It's a complete, crowd-pleasing meal.

Ingredients

Why this recipe works

Pounding the chicken to an even 1/2-inch thickness is the secret to even cooking. Thin cutlets fry quickly, so they stay juicy inside while the crust turns golden and crisp. This also creates more surface area for the crunchy coating, maximizing the satisfying crunch in every bite.

The buttermilk soak does double duty: it tenderizes the chicken and provides the moisture that makes the flour cling.

Pressing the flour into the wet chicken creates craggy flakes that fry up into an extra-crispy, textured crust. The seasoned flour adds layers of flavor, so the coating tastes as good as it looks.

Notes and substitutions

Use boneless, skinless chicken breasts and pound them yourself for the best results. Buttermilk is key; if you don't have it, mix whole milk with lemon juice and let it sit for 5 minutes.

The garlic herb mayonnaise can be store-bought or homemade—just make sure it's creamy and full-flavored.

For the crispiest crust, use a wire rack to let the coated chicken rest before frying; this helps the coating adhere. A thermometer is essential for keeping the oil at 350°F (175°C) so the chicken cooks through without burning. Brioche buns are soft and slightly sweet, but any soft bun works.
