An easy Chicken a la King sauce that comes together fast on the stovetop! Rich, creamy and loaded with a hearty mix of tender chicken, mushrooms, peas, celery, and peppers.
Add the butter to a large skillet (with a fitted lid) or a Dutch oven over medium-high heat. As soon as the butter has melted, add the diced bell pepper, onion, celery, mushrooms, 1 teaspoon Kosher salt and ½ teaspoon black pepper. Stir the mixture until evenly coated in the butter. Reduce the heat to medium, cover and cook for about 6 minutes -- just until everything has softened.
Sprinkle the flour over the vegetables and stir for about 1 minute. Add the chicken broth one big splash at a time, stirring until completely mixed and smooth after each addition.
Once all of the broth has been incorporated, stir in 1 teaspoon Kosher salt, ½ teaspoon pepper, garlic powder, and paprika. Simmer for 2-3 minutes, or until slightly thickened.
Stir the peas and the cream, and bring to a simmer. Simmer for about 5 minutes more, then stir in the chicken.
