Preheat oven to 350 degrees F. On a parchment lined baking sheet, place phyllo dough shells and fill them with a chunk of brie cheese, about 1/2 tbsp. Bake for 7-10 minutes of until brie cheese is melted and shells are golden brown. Remove from oven

Layer a dollop of cranberry sauce on top of the brie cheese, then add some crispy fried onion pieces and a light sprinkle of dried rosemary. I like to serve with the remaining brie cheese and cranberry sauce on the side to enjoy with crackers too
