Remove the bacon from the oven and place on stacked paper towels to remove excess grease. Reduce oven temperature to 375 degrees.
When bacon is cool enough to touch, yet still warm and flexible...
Line the bottom of each prepared muffin cup with a piece of bread. Line the side of each cup with a rounded piece of bacon. Crack an egg into the center of the cup you created, being careful not to crack the yolk.
Bake for 18 minutes until the whites are completely set and the yolk is still slightly runny. (Bake 2 additional minutes for fully cooked yolks.)
Run a knife around the edge of each cup and lift out with a spoon.
Serve warm. Enjoy!
