Overnight oats soften in the refrigerator, so the morning work is mostly stirring and adding toppings. Use rolled oats for a familiar texture and leave space in the jar for the mixture to expand.
Stir rolled oats with yogurt and milk, divide into covered containers and refrigerate for 6–12 hours. Stir again before eating and add a splash of milk if the mixture is too thick.

Keep milk and yogurt refrigerated. Wash fresh fruit and use clean containers. This is a refrigerator soak, not a jar left on the counter overnight.

Ingredients
Base batch: 2 breakfasts
Ingredient amounts scale; oven temperatures and cooking times do not. Split a larger batch between pans when needed.
For the best fruit texture, prepare only a few days at a time and keep every portion cold.
Let’s do this
Step by step
- 01
Mix the base
Combine oats, yogurt and milk in a bowl. Stir right down to the bottom so dry oats do not remain in pockets.
- 02
Divide and cover
Spoon into two containers with room for stirring. Add fruit now for a softer mixture or reserve it for the morning. Close the lids.
- 03
Chill overnight
Refrigerate for 6–12 hours at 40°F or below. The oats absorb moisture while cold. Do not substitute a room-temperature soak.
- 04
Adjust and serve
Stir thoroughly. Add a small splash of milk if too thick and finish with fruit or cinnamon. Keep the second portion refrigerated until you need it.

Choose toppings for the texture you like
Soft fruit can mix in overnight; nuts, toasted seeds and crunchy cereal stay crisper when added at serving. Keep toppings separate when preparing several portions.

Common questions & sticking points
Can I use steel-cut oats?
They need a different preparation and will remain much firmer in this formula. Use rolled oats for the stated method.
Can I eat them warm?
Yes. Use a microwave-safe bowl rather than heating a closed jar, stir during heating and handle carefully.
