Preheat oven to 350 degrees Fahrenheit and grease muffin pan with cooking spray.
Cook bacon in frying pan for 5-8 minutes over medium heat. Do not cook all the way through.
Remove bacon from frying pan and set aside to cool momentarily on a paper-towel lined plate. Once cool, use bacon to line the sides of each muffin cup.
Crack one egg into each bacon-lined muffin cup.
Sprinkle salt and pepper for taste.
Bake eggs and bacon for 12-20 minutes depending on your egg-texture preference.
