Mix all the ingredients together. Mixing well, but some lumps are ok. Remove the skillet from the oven and pour in the batter. Return to the preheated oven and bake for 20–25 minutes. Cool and save for dressing.
Next, add the broth, one cup at a time, until desired consistency is reached. Keep in mind that a lot of the liquid will evaporate during cooking, so 2 cups is a good rule for a firm yet moist dressing.
