Buttery Herb Spatchcocked Chicken w/ Carolina Mustard Sauce
Few backyard cooks realize just how much difference one simple technique can make to a whole chicken. Spatchcocking -- removing the backbone and flattening the bird (read our guide on spatchcocking a bird here) -- allows the chicken to cook more evenly, exposing more skin directly to the heat. The result is exactly what every pitmaster wants: crispy, golden skin on the outside and juicy, tender meat throughout. It’s a simple step that turns an everyday chicken into a true grill centerpiece.
In this recipe from the American Flame BBQ Box, the flavor starts with Hi-West Buttery Montana Herb Seasoning, a rich blend that brings savory herbs, buttery notes, and classic backyard flavor to every bite. Applied generously over a light butter or mayo binder, the seasoning melts into the skin as the chicken slowly cooks over wood smoke. As the fat renders and the herbs toast, the bird develops deep color and a savory crust that smells incredible coming off the smoker.
To finish the dish, Lane’s Southbound Sauce delivers a bright Carolina mustard kick that perfectly balances the richness of the chicken. Brushed on during the final minutes of cooking, the sauce sets into a tangy glaze that cuts through the smoky, buttery flavors without overpowering them. The mustard-forward bite adds just enough acidity to keep every bite bold, balanced, and incredibly satisfying.
It’s the kind of recipe that feels impressive when it hits the table but is surprisingly straightforward to make. Whether you’re cooking for a weekend cookout, a backyard gathering, or just looking for a new way to elevate a whole chicken on the smoker, this buttery herb spatchcocked chicken delivers crowd-pleasing results every time.
