Preheat the oven to 375°F. Coat 6 cups of a muffin tin with cooking spray or line with paper liners.
Crack the eggs into a large bowl and whisk until smooth. Add remaining ingredients; stir to combine.
Divide the egg mixture evenly among the muffin cups. Bake for 15-18 minutes or until eggs are set.
Serve immediately or store in the refrigerator until ready to eat. Enjoy!
