Princess Diana’s breakfast recipe, shared by her private chef, is just as iconic as she is. It’s a Bircher muesli–style dish with citrus-soaked oats and all the best toppings.

Author’s Notes
A Royally Good Breakfast
Princess Diana’s private chef shared the breakfast he used to make for her, and it’s been blowing up on social media. It’s kind of like a mix between overnight oats and muesli, which I already love, but the twist? Instead of soaking the oats overnight in milk or yogurt (like I usually do), he used orange juice.
Of course, I had to try it! I made one batch with freshly squeezed orange juice and another with clementine juice.
You guys…Princess Diana’s breakfast is AMAZING. I’m fully obsessed with it!
The toppings she loved take it over the top: a grated apple, creamy vanilla yogurt, fresh blueberries, toasted nuts, and a drizzle of honey. Absolute perfection.
And it’s so easy. Just squeeze citrus over oats, let them sit overnight, and pile on the toppings in the morning. Wow! Trust her to turn breakfast into something this iconic.
Princess Diana’s Breakfast Ingredients
Ingredient | Tip |
---|---|
Oats | Use old-fashioned oats for the best texture. Quick oats can get mushy, and steel-cut won’t soften enough overnight. |
Clementine juice | Freshly squeezed orange juice works too, but I preferred the flavor and sweetness of clementines. Squeeze the citrus yourself; skip the bottled juice. |
Vanilla & salt | A splash of vanilla and a pinch of salt make the oats taste balanced instead of flat. |
Apple & blueberries | Grate the apple right before serving so it stays fresh. Blueberries add a pop of sweetness. |
Walnuts, Greek yogurt & honey | Toast the nuts for crunch, use creamy high-quality yogurt for richness, and finish with honey for just the right sweetness. |
Storage
Store the citrus-soaked oats in an airtight container in the fridge for 3–4 days. Add toppings just before serving and enjoy Princess Diana’s Breakfast while the fruit and nuts are still fresh and crunchy.

Recipe Notes
How To Toast Walnuts
Princess Diana’s breakfast always included walnuts. To make them as flavorful as possible, toast them first:
- Skillet method: Add walnuts to a dry skillet over medium heat. Stir often for 4–6 minutes until fragrant and lightly browned. Remove right away so they don’t burn, then let cool.
- Oven method: Spread walnuts on a baking sheet in a single layer. Bake at 350°F for 7–10 minutes, stirring halfway through, until golden and fragrant. Let cool before using.
Variations
