Preheat oven at 400 degrees, and lay frozen waffle fries in a single layer. Bake as directed on package.
Combine cream cheese and shredded cheddar until well combined. If you need to add more of either cheese, you can do so. This is a very forgiving recipe.
Once waffle fries are cooked, remove them and place a dollop of cheese mixture on top of fries. Return to oven at 350 degrees, for 3-5 minutes or until cheese is melted.
Remove fries from oven and place a slice of bacon on top of the cheese so it adheres to the melted cheese.
Serve warm, with sour cream on the side if desired.
