Mary Berry’s Overnight Oats Recipe – Fuss-Free, Creamy, and Morning-Ready

The first time I tried making overnight oats, I made the rookie mistake of using instant oats instead of rolled. By morning, what I had wasn’t creamy—it was more like wallpaper paste. Not my finest breakfast moment.

But once I followed Mary Berry’s approach—keeping it simple, flexible, and just a bit playful—the difference was night and day. Soft but still a little chewy, creamy without being claggy, and the kind of breakfast you can make half-asleep and still feel like you’ve nailed it. Let me show you the tweaks that saved me from mushy oats forever.

What Makes This Recipe Special

Most overnight oat recipes get one thing wrong: they drown the oats. Too much liquid, and you’re left with something closer to soup. Mary’s base ratio (1 part oats to 2 parts milk) just works. Add in yogurt, a touch of honey, and you get a texture that feels more like pudding than porridge.

And here’s the other thing—I didn’t think soaking time mattered much, but it does. Less than six hours, and the oats are chalky. Leave them overnight, and they’re silky smooth by breakfast.

Ingredients + Why They Matter

• Rolled oats (100g / 1 cup) – Old-fashioned oats are non-negotiable. Instant turns mushy, steel-cut never softens.
• Milk (200ml / ¾ cup + 1 tbsp) – I’ve tested oat, almond, and dairy. Almond milk keeps it light, full-fat milk makes it almost dessert-like.
• Greek yogurt (2 tbsp, optional) – Game-changer for creaminess. Once I skipped it, and the oats felt thin and sad.
• Honey or maple syrup (1 tbsp) – Adds gentle sweetness. I’ve tried skipping sweetener, but unless your fruit is very ripe, it falls flat.
• Chia seeds (1 tsp, optional) – They soak liquid and make it feel extra thick—almost like a mousse.
• Fruit (a handful) – Berries sink less than grated apple or banana, but all work if you don’t mind a little color bleed.
• Nuts or seeds (1 tbsp) – Crunch is everything. Toasted almonds are my go-to.
• Cinnamon or vanilla (pinch, optional) – Tiny addition, big payoff in flavor.

Want to Change It Up? Here’s How

• Vegan – Use oat or almond milk + coconut yogurt. Works beautifully.
• Protein Boost – Stir in a scoop of vanilla protein powder before refrigerating. Thickens it even more.
• Apple Pie Version – Grated apple + cinnamon + chopped walnuts. My autumn favorite.
• Mocha Morning – Half a teaspoon of instant coffee + cocoa powder. Surprisingly good.

How to Make Mary Berry’s Overnight Oats

1. Mix the base – In a jar or bowl, stir together oats, milk, yogurt (if using), honey, and chia. The oats should look well-coated, not swimming.
2. Add flavor – Stir in cinnamon or vanilla if you like.
3. Layer in fruit & nuts – Add berries or grated apple now, or save for topping. Nuts stay crunchier if added in the morning.
4. Chill overnight – Cover and refrigerate for at least 6 hours. Don’t rush it.
5. Serve – Stir, taste, adjust sweetness. Add toppings (peanut butter swirl, toasted seeds, extra fruit). Eat straight from the jar.

Tips From My Kitchen

• I prep 3 jars at once—by day three they’re still spot on.
• A sprinkle of sea salt makes the sweetness pop (tiny, but makes a difference).
• If I want it warm, 45 seconds in the microwave does the trick without ruining the texture.
• Toast your nuts before adding—brings out way more flavor.

---

Storage + Serving

• Fridge life: Up to 4 days, though fruit toppings are best added fresh.
• Freezer: Surprisingly, yes! Freeze portions without fruit, thaw overnight in the fridge.
• Serving ideas: Pair with coffee, or pile on stewed apples in winter.

FAQs

Q: Can you make Mary Berry’s overnight oats with water instead of milk?
Yes, you can, but the oats won’t be as creamy. I tested a batch with just water and, honestly, it felt more like cold porridge. If you want dairy-free, use oat, almond, or coconut milk—it keeps the texture rich without feeling heavy.

Q: How long do Mary Berry’s overnight oats last in the fridge?
Up to 4 days if stored in a sealed jar. I usually prep three at once on Sunday night, and by Wednesday morning they’re still fresh. Just wait to add fresh fruit or nuts until serving—otherwise they go soggy.

Q: Can I warm up overnight oats, or are they meant to be eaten cold?
They’re usually eaten chilled, but I’ve microwaved mine for about 45 seconds on a cold morning. The oats stay creamy, and the cinnamon flavor actually comes alive when warm. Just don’t overheat, or it’ll dry out fast.

Q: Which oats are best for Mary Berrys’s overnight oats?
Old-fashioned rolled oats every time. I once tried quick oats (mushy mess by morning) and steel-cut oats (still crunchy, even after two nights). Rolled oats give the perfect balance—soft, creamy, but still with a little bite.

Q: What are the best toppings for Mary Berry’s overnight oats?
Jamie’s base recipe is flexible, but my top-tested combos are:

• Peanut butter + banana (filling & high-protein)
• Berries + Greek yogurt (classic, refreshing)
• Grated apple + cinnamon (tastes like apple pie)
• Mango + coconut flakes (a tropical twist)

Q: Can I make overnight oats without yogurt?
Yes—you can skip it and just add more milk. I’ve done it both ways, and while yogurt gives that lovely pudding-like creaminess, the oats still soften perfectly without it.

Q: Are overnight oats good for weight loss?
They can be. The oats and chia seeds keep you full, and if you skip heavy sweeteners and use fruit for natural sweetness, it’s a very balanced, high-fiber breakfast. My go-to is berries + cinnamon—it tastes indulgent but is actually light.
