Preheat oven to 400 degrees. Spray (12) cavities of a standard muffin cup with cooking spray or use silicone muffin cups (I highly recommend them and no greasing is necessary! See affiliate link above).

Wrap one slice of bacon around the inside of each muffin cup and bake for 7-10 minutes (see notes on bacon thickness). Remove from heat and drain the grease. Reposition the bacon in the muffin cup if necessary to make more room for the eggs.

Crack an egg into the center of each muffin cup, being careful to keep it inside the bacon slice. Sprinkle the top of each egg with salt and pepper, to taste, and bake for 12-15 minutes more depending on the desired amount of doneness (see notes). 12 large eggs,salt and pepper

Remove from the oven and place on a wire rack for 5 minutes. Remove from the muffin cups, serve with chopped fresh chives if desired and enjoy! 1/4 cup chopped chives
