Dredge 2 pounds boneless, skinless chicken breasts in the flour until fully coated.

Add 2 tablespoons unsalted butter to a large cast-iron or oven-safe skillet set over medium-high heat.
4 tablespoons unsalted butter
Once heated, cook the chicken breasts for 2-3 minutes on each side to brown. Remove the chicken from the pan and set aside on a plate.
Turn down the heat to medium. Add the remaining 2 tablespoons unsalted butter to the pan.

Notes

*Boneless, skinless chicken thighs will also work.

**I recommend choosing a dry white wine like Sauvignon Blanc, Chardonnay, Riesling, or Pinot Grigio. In place of the white wine, use an equal amount broth.

***For a lighter flavor, use chicken broth instead of beef broth.

****Swiss is the next best substitute for gruyere.

Tips:

To help the flour stick to the chicken, do not pat the chicken dry!
For toastier cheese, place the pan under the broiler for a few minutes!
