How much fat is in mashed potatos?

Mashed potatoes can vary in fat content depending on the ingredients and preparation method used. Typically, mashed potatoes made with milk and butter will contain more fat than those made with only water or plant-based milk. On average, a 1/2-cup serving of mashed potatoes made with milk and butter contains around 9-10 grams of fat. However, this can vary depending on the specific recipe and ingredients used.
