– In a heavy large skillet, add olive oil and butter over medium high heat. Once mixture is melted and hot, add the celery and onions, cooking until onions are browned and translucent. Add remaining ingredients up to (but not including) cubed stuffing. Cook 1-2 minutes, stirring, and turn off heat. Add stuffing cubes and stir gently to combine. Add 2 cups of broth until bread is softened and moist. At this point, you can choose to cover and chill overnight or continue on with recipe.
– When ready to bake, preheat oven to 375F with rack on lower middle position. Use rubber spatula to gently stir stuffing mixture and add more broth as needed (may not need to add much, depending on how soft you like your stuffing.)
– Butter a 12-muffin tin generously. Divide stuffing mixture evenly into muffin tin. Bake 10-15 min or until nicely browned on top. Stuffing muffins can be served fresh out of the oven or a couple of hours later (they can easily be reheated if you like.)
