Chicken a la King is rich, creamy, and hearty comfort food. This 30-minute dinner recipe contains chicken and veggies in a cream sauce made from scratch.
Add butter to a large skillet and melt over medium-high heat until it starts to bubble, about 1 minute. Add mushrooms and sauté until golden brown on both sides, about 5 minutes.
Stir in onion, garlic, salt, and pepper. Cook for another 2-3 minutes until the color turns nicely brown (salt will further extract more water from the mushrooms, giving them a nice brown color).
Add flour and stir well until thickened into a paste, about 1 minute.
Slowly pour in chicken broth and heavy cream. Stir constantly until smooth and bring the mixture to a simmer. Let it simmer over medium-low heat until thickened to a desired consistency, about 2-3 minutes, stirring often. If the sauce gets too thick, thin it out with more chicken broth.
Add peas, pimentos, and chicken. Mix well and cook until heated through, about 2-3 minutes.
Serve immediately in serving bowls with a sprinkle of chopped parsley (if desired) and topped with biscuits or serve over pasta or rice.
