Cook the Chicken Breasts: Add chicken breasts to the skillet and cook until golden brown on both sides.
Simmer with Savory Sauce: Stir in soy sauce and chicken broth, bringing the mixture to a simmer. Cook until the chicken is fully cooked through, about 20 minutes.
Boil and Mash the Potatoes: Bring a pot of salted water to a boil and add the diced potatoes. Cook until tender, then drain and mash with milk, butter, salt, and pepper.
Assemble and Serve: Serve the glazed chicken breasts over a scoop of creamy mashed potatoes, drizzling the pan sauce on top.
