To store uneaten cooked bacon, label, and place in an airtight container in the refrigerator for 3-5 days. I save leftovers for quick breakfasts, or crumble a piece of bacon to make bacon bits for a garnish for other dishes. You can even use a slice of bacon or two, to add bacon into breakfast burritos. If you have several bacon slices leftover, you can use them in a blt sandwich too.
