The traditional recipe for green bean casserole calls for butter, full-fat milk and sour cream which, while adding richness, seriously bump up the saturated fat. We call for low-fat milk and reduced-fat sour cream. We also use tangy buttermilk powder to add depth of flavor but not a lot of calories or fat (look for it in the baking section of your supermarket).You get tons of flavor and 8 grams less saturated fat than traditional versions.
