Who knew Princess Diana was enjoying overnight oats long before they became trendy?

Her former private chef, Darren McGrady, recently shared a YouTube video with the overnight oats recipe that she requested almost every morning and they’re now going viral on TikTok and Instagram. As a huge overnight oats fan I had to try them for myself!

Overnight Oats Fit For a Princess

I’m always looking for breakfasts that feel a little special but are still practical for busy mornings, and this recipe totally nails it. Princess Diana’s overnight oats are nourishing, refreshing and surprisingly have a good amount of protein. Plus they come with a backstory that makes breakfast feel a little more special. Here’s why I know you’ll love them:

High-protein: About 20 grams per serving so you’ll actually stay full until lunch.
Bright & refreshing: Orange juice-soaked oats with a touch of lemon.
Great texture: Creamy yogurt, juicy blueberries, grated apple, and crunchy walnuts.
Meal prep friendly: Quick to prep ahead so mornings feel effortless.

Ingredients Needed

rolled oats: old-fashioned oats soak up the citrus juice without turning mushy, making them perfect for overnight oats.
orange juice: Princess Diana’s former chef used freshly squeezed orange juice, but I opted for store-bought orange juice out of convenience. Either option works great!
greek yogurt: creates a creamy base and adds about 20 grams of protein per serving. I like using a thick brand like Fage or Chobani for the best texture. Use a dairy-free yogurt if you need this recipe to be dairy-free.
honey or maple syrup: balances the tang of the citrus and yogurt with natural sweetness.
lemon juice: prevents the apple from browning while adding some brightness.
cinnamon: adds warmth and depth without extra sugar.
apple: grated right into the oats for natural sweetness, fiber, and texture.
blueberries: fresh and juicy, they bring color, antioxidants, and a burst of flavor.
walnuts: chopped and toasted for crunch, healthy fats, and omega-3s. Use any nut of choice or skip for a nut-free version.

My Overall Thoughts

I’m not an orange juice lover so I wasn’t sure I would love these, but the citrus flavor grew on me. I will say that these oats a bit higher in carbs and sugar, but they do pack a decent amount of protein (20 grams) and fiber (8 grams). Definitely a fun recipe to try if you’re looking to switch up your breakfast, but probably not something I would make on regular rotation.

How to Store

These overnight oats are perfect for meal prep because they stay fresh for several days.

Refrigerator: Store in an airtight container or individual jars for 3–4 days. The flavors get even better as they sit, but the oats will continue to soften over time.
Mix-ins later: For crunchier walnuts or fresher blueberries, keep them separate and add right before serving.
Freezer: Overnight oats don’t freeze well, so stick to fridge storage only.
