These egg white muffins are a healthy and easy breakfast. They are small and portable and can be prepared ahead of time for your weekly breakfast meal prep.
Preheat oven to 350°F. Grease 10 cavities of a 12-cup nonstick muffin pan with cooking oil spray.
In a large bowl, add egg whites, spinach, peppers, mushrooms, 2/3 of the cheese, scallions, salt and pepper. Whisk until evenly combined.
Using a 1/3 cup, scoop out batter and pour into muffin cavities. You should have enough batter and ingredients to make 10 muffins. Sprinkle remaining cheese over the surface of the muffins.
Bake for about 20-22 minutes or until muffins have puffed up and egg whites are completely cooked. Muffins will sink back down as they cool.
Muffins are best eaten warm. They can be stored in the fridge or freezer.
Notes
To save time separating eggs, this recipe can also be made with liquid egg whites.
All ingredient measurements should be taken after they have been chopped.
The muffins can be stored in the fridge or freezer. I prefer the fridge because freezing them will change the texture a little.
I usually reheat mine in the microwave. Because of the vegetables, the egg muffins will release water during reheat, so I recommend lining a plate with a paper towel before reheating in the microwave.
Make sure to grease your muffin pan even though it is nonstick. This will ensure that the muffins will pop right out and won't stick to the pan.
