Use day-old bread or dry fresh bread in the oven to avoid mushy stuffing. Butter adds richness but can be substituted with olive oil for a dairy-free option. Fresh herbs are preferred over dried for better flavor. Add stock gradually to achieve perfect moisture. Toasting bread cubes before mixing adds texture. The stuffing mixture can be made ahead and refrigerated before baking. Variations include adding sausage, nuts, fruits, cheese, or using vegan substitutions.
