What Are Overnight Oats?
Overnight oats are oats soaked in liquid (juice, milk, or yogurt) and left in the refrigerator overnight. This process softens the oats, creating a creamy texture without cooking. Princess Diana’s version uses clementine juice for a refreshing citrus twist and can be topped with a variety of fresh fruits, nuts, or yogurt for added flavor and nutrition.
Cooking Tips
- Use fresh clementines for the best flavor; freshly squeezed juice elevates the oats.
- Choose old-fashioned oats instead of instant for a chewier texture.
- Mix toppings gently to avoid breaking delicate fruits like blueberries.
- Prepare the night before to save time in the morning.
