Preheat Oven and Prepare Pan: Preheat your oven to 350°F. Grease a 9X13 inch square baking pan and set aside.
Cream Cream Cheese: Add the softened cream cheese to a large bowl and cream using a handheld mixer on medium speed until light and fluffy.
Zest Orange: Use a zester to zest a large orange over the cream cheese.
Add Cheese and Cranberry Sauce: Grate and add 2 cups of extra sharp white cheddar and spoon in 2 cups of cranberry sauce to the bowl. Mix together until all the ingredients are combined.
Add Fresh Cranberries: Add the whole, fresh cranberries to the bowl and fold in until evenly incorporated.
Pour in & Bake: Spoon in the cream cheese mixture into the prepared baking dish and smooth out. Sprinkle remaining 1 cup of cheese over the top of the cream cheese mixture and evenly dollop the extra cranberry sauce over the top of the cheese. Bake uncovered for 25 minutes, then broil for additional 1-2 minutes until top is golden and bubbly.
Serve Warm: Remove the dish from the oven and let sit for 5 minutes before serving, it will be piping hot. Garnish with a few fresh cranberries and rosemary for a festive vibe.
