Nearly three decades after the death of Diana, Princess of Wales, her former personal chef, Darren McGrady, revealed that her favorite breakfast was overnight oats, a soaked oatmeal dish prepared the night before. The recipe, which exploded on social media in recent years, was already a staple for Diana in the early 1990s, well before it became a global trend. McGrady, who worked for the princess at Kensington Palace, shared details in a YouTube video, highlighting her preference for healthy eating. The revelation, made on August 1, 2025, reinforces Diana’s legacy as an icon of a balanced lifestyle.
The recipe, according to the chef, was discovered by Diana during a trip to Switzerland, where she encountered the concept of bircher muesli, created in the early 20th century. From then on, the dish became part of her morning routine, served with fresh and nutritious ingredients.
McGrady, now 65, detailed how he prepared the dish for the mother of Princes William and Harry, emphasizing the simplicity and nutritional benefits of the recipe.
- Main ingredients: rolled oats, orange juice, yogurt, and honey.
- Variations: included blueberries, walnuts, apple crisps, or chia seeds.
- Preparation: oats were soaked overnight for better texture and flavor.
Origin of the favorite recipe
The history of overnight oats dates back to the early 20th century, when Swiss nutritionist Maximilian Oskar Bircher-Benner developed bircher muesli. The dish, initially served in health clinics, combined oats, fruits, and dairy for energy and convenience. Diana, upon trying the recipe in Switzerland, brought the idea to the UK, adapting it to her lifestyle.
McGrady noted that the princess ate the dish almost daily, especially during periods when she prioritized her physical health. He served the mixture in glass cups, garnished with fresh fruits, making the breakfast visually appealing. The recipe was so popular that even the palace staff requested extra portions.
The chef also revealed that Diana preferred natural ingredients, avoiding refined sugars. The use of raw honey and fresh juices, for instance, reflected her commitment to a balanced diet.
Rise of overnight oats
Although overnight oats gained global fame around 2012, driven by social media platforms like Instagram and Pinterest, Diana was enjoying it nearly two decades earlier. McGrady emphasized that the princess was ahead of her time, embracing healthy eating trends long before they became mainstream.
The recipe is now widely known for its versatility and nutritional benefits. Nutritionists highlight that oats are rich in fiber, aiding digestion and cholesterol control. Combining them with yogurt and fruits adds protein and vitamins, making the dish ideal for sustained energy.
