Spray a 12-cup muffin pan with non-stick cooking spray (the heavier you spray, the less it will stick) or use thick muffin liners.
In a large mixing bowl, beat eggs. Add in remaining ingredients and mix together.
Scoop ⅓ cup of mixture into each muffin liner.
Bake for 20-25 minutes or until the center of the muffin is completely cooked.
Notes
After you have made your egg muffins and let them cool down, you can store them in an air-right container in the fridge for up to 4-5 days.
You can also place them in a resealable gallon-sized bag or freezer-safe container for up to 60 days. To keep them as fresh as possible while in the freezer, some of our readers have recommend individually wrapping each muffin.
Removed your scrambled egg muffin from the fridge or freezer. Reheat until it's warmed all the way through to the center of the muffin. Start with 30 seconds and then add on 10 second intervals until warm.
