What Is ‘Overnight Oats’ And Why To Make It
Overnight oats are a simple, no-cook method of preparing oats by soaking them in liquid—usually milk or a milk alternative—overnight in the fridge. This soaking softens the oats, making them creamy and ready to eat straight away the next morning without any cooking.
Why make overnight oats? They’re a fantastic, time-saving breakfast option that’s nutritious, convenient, and customizable. Because they soak overnight, they’re ready to grab and go, perfect for busy mornings. Plus, you can pack them with wholesome ingredients like fruits, nuts, seeds, and natural sweeteners to create a balanced meal high in fibre, protein, and essential vitamins. Overnight oats are also gentle on digestion and help keep you feeling full and energized throughout the morning.
Tips
- Prep ahead: Make several jars at once for a quick grab-and-go breakfast all week long.
- Blueberry compote shortcut: Use frozen blueberries to save time—they break down quickly and taste just as delicious.
- Milk swaps: Use any plant-based milk or dairy milk according to your preference or dietary needs.
- Sweetener options: Swap honey for maple syrup or agave for a vegan version.
- Boost protein: Add a scoop of your favourite protein powder or some chopped nuts/seeds for extra protein and crunch.
- Texture tip: If you prefer a thinner consistency, add a splash of milk in the morning before eating.
- Storage: Keep in the fridge for up to 3 days, perfect for meal prep.
Swaps
Oats: Use gluten-free oats if needed or try rolled oats for a creamier texture. Avoid quick oats as they can get too mushy overnight.
Chia seeds: Flaxseeds or hemp seeds work well as a fibre and omega-3 boost.
Milk: Any plant-based milk like almond, oat, or coconut milk can be used, or dairy milk if preferred.
Yoghurt: Greek yoghurt can be swapped for dairy-free yoghurt or skyr for extra protein.
Honey: Maple syrup or agave nectar are great vegan alternatives.
Blueberries: Use any berries you like, such as raspberries, strawberries, or blackberries. You can also mix frozen berries — just thaw before layering.
Lemon zest and juice: Lime zest and juice work as a fresh substitute for a slightly different citrus flavour.
Storage
Fridge: Store in an airtight container for up to 2-3 days. Enjoy cold straight from the fridge or give it a quick stir before eating.
Freezer: Not ideal for freezing overnight oats as the texture changes and becomes watery after thawing. Best enjoyed fresh.
