Heat a large saute pan over medium-high heat until warmed. Add the oil. During heating, dip the chicken breasts
into the eggs
, and then dust
each breast with seasoned flour on both sides. Once floured, add to the oiled pan, reduce the heat to medium and cook until light brown in color, 3 to 4 minutes. Flip and repeat cooking for a final 3 to 4 minutes. Once cooked, remove the breasts from the pan and allow to finish with carry-over cooking.
Return the same pan to the heat and add the stock. Allow to simmer and reduce by three-quarters of the volume. After reducing, whisk in the butter to create a sauce, removing from the heat during the process. Finally, finish with lemon juice and parsley and serve over the chicken.
