Expert Tips and Variations
You can swap regular milk with unsweetened almond milk or add different proteins like sausage, bacon, or leftover chicken for variety. Throw in some spinach, bell peppers, or mushrooms to make it extra nutritious. Be careful not to overbake doing so can make the eggs rubbery. For a flavor boost, sprinkle a little smoked paprika or shredded cheddar on top before baking.
