Nutritional Benefits

This Make-Ahead Breakfast Egg Casserole is not only delicious but also offers numerous health benefits. Eggs are an excellent source of protein, which helps in muscle repair and keeps you feeling full longer. The addition of vegetables like bell peppers and onions adds fiber and essential vitamins, making this dish a balanced option for breakfast.

If you choose to include meats like ham or sausage, you add even more protein, but you can easily keep this dish lighter by skipping the meat altogether. This way, it can fit into various dietary lifestyles, including vegetarian or low-carb diets.
