What are overnight oats?

Overnight oats are simply oats soaked in liquid (milk, yogurt, or a dairy-free alternative) until they soften. Think of them as oatmeal's cooler, meal-prepped cousin that you don't have to slave over the stove making.

Overnight oats vs porridge: Porridge is hot and cooked, while overnight oats are cold (unless you reheat them) and no-cook. Both are filling, but overnight oats win for convenience.

What are the best oats for overnight oats?

Here's the breakdown:

• Rolled oats (old-fashioned oats): The gold standard - creamy, soft, reliable.
• Instant oatmeal (quick oats): Works, but can go mushy quickly.
• Steel-cut oats: Chewy, nutty, but need more liquid + longer soak (often 24 hrs).

What's the oats to liquid ratio?

The sweet spot is usually ½ cup oats to ¾ cup liquid. Adjust depending on whether you like thicker (less liquid) or looser (more liquid) oats.

Best milk for overnight oats?

• Dairy milk: Creamy, classic and highest in protein and calcium.
• Almond milk: Light, slightly nutty. Can be a little watery so aim for a "barrister" style milk.
• Soy: My go-to for dairy-free - super creamy, great texture and most similar to dairy milk.
• Oat milk: The success will depend on your brand. Some are super creamy and will act like soy and dairy milk, but others are more watery and act like almond milk.
• Coconut milk: Rich, slightly tropical, can also be runny and more "watery" depending on the brand.

How to make it higher protein

• Greek yogurt: Thick, creamy, extra protein.
• Protein powder: Great for high protein overnight oats (but mix thoroughly to avoid clumps). If heating in the morning, add after or use a vegan protein powder.
• Nut butters / seeds: Peanut butter, almond butter, chia, flax.

Chia seeds vs flax

• Chia seeds: Thicken oats into a pudding-like texture.
• Flaxseed: Milder thickener, nuttier flavor, more subtle.

How to store and reheat overnight oats

• Fridge life: 4-5 days.
• Freezer: Yes - freeze in portions, thaw overnight in the fridge.
• Microwave Reheating: Add a splash of liquid, stir and reheat on 1 minute intervals until heated through
• Stove. Warm gently with an extra splash of milk.
• Jar size: 225ml - 350ml (8-12 oz) mason jars or reusable containers work perfectly.
