Baked egg muffins can turn out soggy if too much liquid is added to them, or if the vegetables release a lot of liquid. To keep this recipe super simple, I didn't saute the vegetables for this recipe (which a lot of egg muffin recipes have you do). However, I also didn't add any liquid, such as milk, to the egg mixture. So, you shouldn't have any issues with soggy egg muffins if you follow my recipe as written!
