オーバーナイトオーツ
Overnight oats are rolled oats soaked cold in milk and yogurt until they swell into a thick, spoonable, pudding-like breakfast — no stove, no cooking. Chia seeds do the quiet work overnight, setting the mixture into something creamy and just barely sweet, ready to grab straight from the jar. Because the oats hydrate slowly in the fridge, they stay tender instead of gummy, and a single bowl divides into ready-to-eat mornings all week.
Stir together 1 cup rolled oats, 2 tablespoons chia seeds, and a pinch of salt, then mix in 1 cup milk, ½ cup yogurt, 2 tablespoons maple syrup, and 1 teaspoon vanilla until the mixture is loose and soupy; divide between two jars, seal, and refrigerate at least 6 hours or overnight. In the morning stir each jar, loosen with a splash of milk if it set too thick, taste for sweetness, and top with berries, sliced banana, and a swirl of almond butter before eating cold.
- Use old-fashioned rolled oats at a roughly 1:1 oats-to-liquid ratio — quick oats turn mushy and steel-cut oats stay hard.
- Chia seeds create the thick, creamy set; stir the mix once, wait 5 minutes, then stir again so they don't clump on the bottom.
- Add fresh fruit only just before eating so it stays bright; the plain oat base keeps up to 5 days in the fridge.
Equipment
- Two 350 ml (12 oz) mason jars or airtight containers
- Medium mixing bowl
- Measuring cups and spoons
- Spoon or small whisk
- Refrigerator
材料
For the oat base
- 100 g old-fashioned rolled oats, not instant or steel-cut
- 240 ml milk of choice, dairy or unsweetened plant milk
- 120 g plain Greek yogurt, or regular plain yogurt
- 24 g chia seeds, thickens and adds fiber
- 30 ml pure maple syrup, or honey, to taste
- 5 ml vanilla extract
- 1 g fine salt, balances the flavor
For serving (optional)
- 150 g mixed fresh berries, strawberries, blueberries, or raspberries
- banana
- 32 g almond butter, or peanut butter
作り方
- ステップ01
In a medium bowl, or straight in your jars, stir together the rolled oats, chia seeds, and a pinch of salt so the chia is evenly dispersed and won't clump into a jelly later.
- ステップ02
Pour in the milk and yogurt, then add the maple syrup and vanilla. Stir for 20 to 30 seconds until no dry pockets of oats remain and the mixture looks loose and soupy — it will thicken considerably as it sits.
- ステップ03
Divide the mixture between two 350 ml (12 oz) jars, scraping down the sides. Let them sit 5 minutes, stir once more to break up any chia clumps on the bottom, then seal tightly.
- ステップ04
Refrigerate for at least 6 hours, ideally overnight. The oats and chia absorb the liquid and swell into a creamy, spoonable, pudding-like texture.
- ステップ05
Give each jar a good stir. If it set thicker than you like, splash in 1 to 2 tablespoons of milk. Taste and add a little more maple syrup if needed.
- ステップ06
Spoon the berries and sliced banana over the top and finish with a swirl of almond butter. Eat cold straight from the jar, or warm it briefly if you prefer.
Make ahead
This is a natural batch recipe: scale it up and portion 3 to 5 jars of the base at once on a Sunday for grab-and-go breakfasts all week. Store the jars sealed in the fridge and dress each one with fruit and almond butter the morning you eat it.
Storage
Cover and refrigerate the plain oat base up to 5 days — it actually improves after the first night. Keep fresh fruit and nut butter separate and add them only when you're ready to eat, so the toppings stay bright and don't weep into the oats. Freezing isn't recommended, as thawed oats turn watery and lose their creamy set.
Variations
Vegan overnight oats
Swap the dairy milk for unsweetened almond, soy, or oat milk and use a coconut- or soy-based yogurt. Keep the maple syrup instead of honey. The texture stays just as creamy and the recipe becomes fully plant-based.
Chocolate peanut butter
Whisk 1 tablespoon unsweetened cocoa powder into the milk before adding, then stir 2 tablespoons peanut butter into the base. Top with banana and a few dark chocolate chips for a dessert-like breakfast.
Apple cinnamon
Add ½ teaspoon ground cinnamon and 3 tablespoons grated apple to the base, and use half milk, half apple juice for the liquid. Finish with chopped walnuts and an extra drizzle of maple syrup.

よくある質問
How to make overnight oats so they come out creamy, not mushy?
The key to how to make overnight oats with the right texture is using old-fashioned rolled oats and a roughly 1:1 ratio of oats to liquid, plus chia seeds to bind everything. Rolled oats hydrate slowly and hold their shape overnight, while chia thickens the surrounding liquid into a soft pudding. Stir once, wait five minutes, and stir again to keep the chia from settling into clumps.
Can I use quick oats or steel-cut oats instead?
Quick or instant oats work in a pinch but soak up liquid fast and can turn pasty, so use a little more milk and eat them within a day or two. Steel-cut oats stay stubbornly firm when soaked cold and are better cooked, so they're not a good swap for this no-cook method.
How long do overnight oats last in the fridge?
The plain base keeps well for up to 5 days in a sealed jar, which is what makes it such a good meal-prep breakfast. Add fresh fruit and nut butter the morning you plan to eat each jar rather than at the start, so the toppings don't go soft or bleed color into the oats.
Do you eat overnight oats cold or warm?
They're designed to be eaten cold straight from the fridge, which is the whole appeal — no cooking required. If you prefer a warm bowl, microwave a jar (metal lid removed) for 60 to 90 seconds and stir; the texture loosens slightly but stays creamy.
Are overnight oats actually healthy?
Yes — this version is high in fiber from the oats and chia, gets protein from the yogurt, and lets you control the sugar since you add the sweetener yourself. Soaking oats overnight also makes them easier to digest. Watch portion sizes on nut butter and syrup if you're keeping calories in check.
