Fieri’s says that the incredible texture comes from “pounded chicken and crispy toasted baguette pieces.” Start by pounding the chicken ever so slightly with a meat mallet.
Coat the chicken with sour cream, granulated onion, and granulated garlic. Let the chicken marinate in the refrigerator while onions sizzle with butter in a cast-iron skillet.
Cook the chicken for several minutes, form the flour into a roux, add beef stock, and simmer. Cook the chicken on the bed of caramelized onions and cover with the remainder.
Place baguette slices, shredded gruyère, and provolone on top. Bake in the oven for 15 to 20 minutes, and garnish the final product with chopped chives.
