Preheat your oven to 400 degrees F. Lightly grease four nonstick muffin tin cups and line each of them with a ham slice, as shown in the video below.
Break an egg into each cup. Season them with salt, pepper, onion powder, and red pepper flakes.
Bake until the eggs are set, 12-15 minutes.
Cool the cups for 5 minutes in the pan. Then slide a spoon underneath each cup to release them from the pan. Serve immediately.

Notes
*I use large eggs in most of my recipes. But in this recipe, medium eggs actually work better and prevent an overflow of eggs from the cups.Another option, if your eggs are very large, is to pour out a bit of the egg white into the sink before pouring the egg into the ham shell.
