Creamy chicken à la King features tender chicken in a rich mushroom and pimiento cream sauce served over toast points or biscuits. This classic, protein-packed chicken dish is a retro family favorite.
Melt the unsalted butter in a large skillet over medium heat. Add the sliced mushrooms and cook for 4–5 minutes, stirring occasionally until tender and most liquid evaporates.
Sprinkle the flour over the mushrooms and stir constantly for 1–2 minutes to form a roux, taking care not to brown.
Gradually whisk in the chicken broth and milk, stirring constantly to prevent lumps. Raise the heat to medium-high and cook until the sauce thickens, about 4–5 minutes.
Add the cooked chicken, red bell pepper, peas, and pimientos to the thickened sauce. Reduce heat to low and simmer for 5 minutes to warm through, stirring occasionally.
Season with kosher salt, black pepper, and ground nutmeg. Simmer for an additional 2–3 minutes, adjust seasoning if needed, and serve hot over toast points or fresh biscuits.
