Overnight oats are a simple and nutritious breakfast option made by soaking rolled oats in liquid, typically milk or yogurt, overnight. This process allows the oats to absorb the liquid, softening them and making them ready to eat in the morning without cooking. They can be customized with various toppings like fruits, nuts, and sweeteners, making them versatile and enjoyable. This no-cook method is convenient for busy mornings, as it requires minimal preparation time. Overnight oats are also a good source of fiber and protein, helping to keep you full and energized throughout the day.
