If you don't normally use cream cheese on bagels and toast, you can incorporate your leftovers into other recipes! Some of my favorite ways to use up leftover cream cheese is to make stuffed French toast. Mix some cream cheese when making homemade mac and cheese or any other cheesy sauce. You can also mix cream cheese into queso dip or nacho cheese to make it creamier. Likewise, you can stir it into other pasta sauces or soups to make them creamier.
