Protein overnight oats: the base recipe and three variants
A base overnight oats recipe with roughly 35 g of protein per serving, exact quantities, eight minutes of prep and three variants for when the same bowl gets dull.

If your mornings are tight and breakfast keeps landing at about 10 g of protein, this sorts out both problems. Overnight oats take eight minutes the night before and come out of the fridge ready to eat, and one serving gets you to roughly 35 g of protein. Below are exact quantities for two servings, then three variants for when the same bowl gets dull.
Prep time and servings
Prep: 8 minutes. Cooking: 0 minutes. Servings: 2.
The mix needs at least 6 hours in the fridge, ideally overnight. If you are batching for the working week, double or triple everything — without fruit it keeps for 3 days.
Ingredients
For two servings:
- 100 g rolled oats (not instant)
- 300 ml semi-skimmed milk, 1.5% fat
- 200 g Greek yoghurt, 2% fat
- 30 g protein powder (about 24 g protein; vanilla or unflavoured)
- 20 g chia seeds
- 1 pinch of salt (about 1 g)
- optional: 5 ml vanilla extract
Fruit goes in separately in the morning — quantities are in the variants section.
Method
- Get out two jars or lidded containers holding at least 400 ml each.
- Into each one put 50 g oats, 10 g chia seeds and half a pinch of salt, then stir the dry mix.
- Whisk the protein powder into the milk separately: 15 g powder into 150 ml milk per jar. Tip powder straight onto oats and you get lumps.
- Pour the protein milk over the oats and stir for 20 to 30 seconds, until everything is wet.
- Add 100 g Greek yoghurt per jar. Stir it through for a creamier texture, or leave it as a layer on top.
- Put the lids on and refrigerate for at least 6 hours, ideally overnight.
- Stir in the morning. If it is too stiff, loosen with 20 to 40 ml milk — chia drinks up a lot of liquid.
- Only now add fruit and toppings, and eat it cold.
Nutrition per serving
These are an estimate per serving, worked out from the quantities above. Your numbers will shift with the protein powder, yoghurt and milk you use.
- Calories: about 435 kcal
- Protein: about 35 g
- Carbohydrates: about 46 g (roughly 8 g of that is fibre)
- Fat: about 11 g
For someone training regularly that is a solid breakfast: enough protein that you are not hunting a snack 90 minutes later, and enough fibre that it is not just fast sugar.
Variants and swaps
1. Berries
Add 80 g raspberries or strawberries per serving in the morning, right before eating. That is roughly 25 to 30 kcal more and almost no extra protein, but you get fibre and a sharpness that cuts the sweetness. If you want the numbers, we have separate pieces on the calories in raspberries and in strawberries.
2. Cocoa and peanut butter
Stir 5 g unsweetened cocoa into the dry mix and add 15 g peanut butter per serving. That takes a serving to roughly 535 kcal, 40 g protein and 19 g fat. It is thicker and holds you longer, so it makes more sense on training days.
3. No protein powder
Drop the 30 g of powder and add 200 g skyr or a low-fat curd cheese instead. A serving stays around 440 kcal and about 34 g protein. The texture is denser, so budget an extra 30 to 50 ml of milk in the morning.
Swaps that actually work
- Milk: soya drink gives you similar protein; almond or oat drinks drop it by about 3 g per serving.
- Chia: 20 g ground flaxseed does the same job, with a less gel-like texture.
- Fruit: sliced kiwi in the morning brings much the same sharpness as berries.
- Sweetener: 5 g honey per serving is about 15 kcal. A ripe banana is cheaper but adds roughly 90 kcal.
When to see a doctor
If this breakfast regularly leaves you bloated, cramping or running to the loo, the usual suspects are lactose or too much fibre at once — try lactose-free yoghurt and 10 g of chia instead of 20 g. Persistent stomach pain, blood in your stool or unexplained weight loss is not a recipe problem; that is one for your GP.
In short
The base is simple: 100 g oats, 300 ml milk, 200 g Greek yoghurt, 30 g protein powder and 20 g chia make two servings of about 435 kcal and 35 g protein each. Whisk the powder into the milk before it touches the oats, leave it overnight, and add fruit only in the morning.
With breakfast handled the rest of the day gets easier — for lunch built the same way, with exact quantities, have a look at the chicken rice bowl with vegetables.
