Trim chicken breasts to get to an even thickness and pat dry with paper towels. Set aside.
Lay out two breading trays. In one of the trays, whisk together all the dry ingredients.
In the second tray, whisk together buttermilk and egg.
Dredge chicken breasts in flour, gently pressing to adhere. Gently shake off excess.
Dip floured chicken breast in egg mixture and turn to coat completely.
Return chicken breasts to the flour mixture for a second coat, being sure to cover all sides. Place on wire rack to rest while you bring the oil to temperature.
Add enough oil to skillet to come about 1/2-inch up the sides of the pan. Heat oil over medium-high until temperature reads 345 F.
Cook chicken for approximately 5-7 minutes per side, or until internal temperature reaches 165 F.
Remove to wire rack and allow to rest for 2-3 minutes. Serve on sandwich buns.
You want to trim the chicken breasts to an even thickness so they cook evenly in the oil.
We use breading trays, but if you don’t have them, shallow bowls, plates, or platters will do the trick.
We use a heat temperature gun whenever we need to heat oil to a certain temperature. It’s accurate and much safer than thermometers that require your hand to get near the hot oil.
