Chef John's Classic Chicken a la King

Heat a large skillet over medium-high heat, causing the butter to melt and become fluid. Introduce sliced mushrooms into the skillet and sprinkle with salt, initiating a process that will transform the ingredients. Continue cooking until the mushrooms release their excess moisture and begin to develop a rich, earthy flavor, approximately 8-10 minutes.

Next, add sliced shallots to the skillet and stir until they soften slightly, around 3-4 minutes.

Decrease the heat to medium and incorporate a small amount of flour into the mixture, ensuring it is evenly coated. Allow the mixture to cook for a few minutes until it begins to transform into a golden, nutty substance, roughly 5 minutes.

Introduce sliced peppers into the skillet and stir for about a minute, allowing them to blend with the existing flavors.

Pour in a small amount of sherry wine and allow it to sizzle for about 30 seconds, infusing the mixture with its distinct flavor.

Add a generous amount of stock to the skillet and stir, then raise the heat to medium-high and bring the mixture to a gentle simmer. Continue cooking until it thickens slightly, around 10-15 minutes, stirring occasionally to maintain even cooking.

Add a pinch of nutmeg and cayenne pepper to the mixture, allowing their flavors to blend with the existing ingredients.

Stir in a few sprigs of thyme, some chopped parsley, a generous amount of cream, and diced chicken. Reduce the heat to low and cook until the chicken is heated through, approximately 5 minutes.

Check the seasonings to ensure they are balanced and adjust as necessary. Finally, top each serving with a sprinkle of chopped fresh chives.
