Princess Diana’s Breakfast is a refreshing and nourishing Bircher muesli-style dish made with citrus-soaked oats, creamy yogurt, fresh fruit, and crunchy walnuts. This elegant breakfast became popular after Diana’s former chef revealed her favorite morning meal. Unlike traditional overnight oats, this version uses freshly squeezed clementine or orange juice to soften the oats overnight, giving the dish a naturally sweet and vibrant flavor. It’s light yet filling, simple to prepare, and perfect for busy mornings.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 1/2 cup old-fashioned oats
• 4 fresh clementines, juiced to make 1/2 cup juice
• Tiny pinch of salt
• 1/8 teaspoon vanilla extract
• 1 Honeycrisp apple, grated
• 1 teaspoon lemon juice (optional)
• 1/3 cup fresh blueberries
• 1/4 cup toasted walnuts
• 1/4 cup honey vanilla Greek yogurt
• 1 to 2 teaspoons honey, to taste

Directions

1. Juice the clementines until you have about 1/2 cup of fresh juice. Fresh juice works best because it gives the oats a vibrant citrus flavor without added sweetness.
2. In a small bowl or mason jar, combine the oats, clementine juice, salt, and vanilla extract. Stir thoroughly to ensure all the oats are coated.
3. Cover the bowl or jar and refrigerate overnight, or for at least 8 hours. During this time, the oats soften and absorb the citrus flavor.
4. In the morning, stir the oat mixture well. If it feels too thick, add a small spoonful of yogurt or a splash of juice to loosen it slightly.
5. Grate the apple just before serving to keep it fresh and crisp. If desired, toss the grated apple with lemon juice to prevent browning.
6. Transfer the oats to a serving bowl and top with grated apple, blueberries, toasted walnuts, and Greek yogurt.
7. Drizzle honey over the top for extra sweetness and enjoy immediately.

Variations

For a berry-filled version, replace the blueberries with raspberries, strawberries, or blackberries.

If you prefer a different nut flavor, try toasted almonds, pecans, or pistachios instead of walnuts.

You can also swap the honey vanilla yogurt for plain Greek yogurt, coconut yogurt, or even almond milk yogurt for a dairy-free option.

To make the breakfast naturally sweeter, add chopped dates, raisins, or dried cranberries.

For extra texture, sprinkle chia seeds, flaxseeds, or granola on top before serving.

Storage/Reheating

Store the soaked oats in an airtight container in the refrigerator for up to 4 days. For the best texture, keep the toppings separate until ready to serve.

This recipe is designed to be enjoyed cold, so reheating is not necessary. However, if you prefer warm oats, gently heat the oat mixture in the microwave for 30 to 45 seconds before adding the toppings.

Fresh fruit and nuts are best added just before eating to maintain their texture and flavor.

FAQs
