High Protein Overnight Oats: 6 Recipes, 25–40 g Protein

High protein overnight oats are made by soaking rolled oats overnight with high-protein ingredients: Greek yogurt or skyr, dairy or soy milk, chia or hemp seeds and, if you like, a scoop of protein powder. That combination takes a jar from around 10 g of protein to between 25 and 40 g, with five minutes of prep the night before. Below is the base ratio, six flavour variations and tips to fix runny or gluey oats.

The appeal is obvious: breakfast is ready when you wake up, it's portable, and it reheats well. Getting the protein up is mostly a question of swapping some liquid for yogurt and choosing the right milk.

The base recipe

Ingredients (one jar)

Optional boosters: 15 g (half a scoop) protein powder adds about 12 g; 1 tbsp hemp seeds adds about 3 g; 1 tbsp peanut butter adds about 4 g.

Method

1. Add oats, chia seeds, salt and cinnamon to a jar.
2. Add yogurt and milk. If using protein powder, whisk it into the milk first to avoid lumps.
3. Stir thoroughly, scraping the bottom.
4. Seal and refrigerate for at least six hours or overnight.
5. In the morning, stir, loosen with a splash of milk if needed, and add toppings.

Which milk gives the most protein?

Swapping almond milk for dairy or soy adds about 3 g to a jar for free, with no change to the method or the taste of the finished oats. Ultra-filtered milks add more.

Six high-protein overnight oats recipes

1. Peanut butter and banana (about 30 g protein)

Base recipe plus 1 tablespoon peanut butter and 15 g vanilla protein powder. Top with sliced banana in the morning.

2. Chocolate protein (about 35 g protein)

Base recipe plus 1 tablespoon cocoa powder, 20 g chocolate protein powder and 2 extra tablespoons of milk. Top with raspberries.

3. Berry cheesecake (about 30 g protein, no powder)

Base recipe, but replace half the yogurt with 80 g blended cottage cheese. Add vanilla and lemon zest, top with mixed berries and a crumbled digestive biscuit. Cottage cheese gives a thicker, cheesecake-like texture. More in high protein cottage cheese recipes.

4. Apple pie (about 26 g protein)

Base recipe plus grated apple, a teaspoon of cinnamon, a pinch of nutmeg and 1 tablespoon hemp seeds. Top with chopped walnuts.

5. Mocha (about 32 g protein)

Base recipe with 60 ml cold coffee replacing half the milk, plus 1 teaspoon cocoa and 15 g chocolate or coffee protein powder.

6. Tropical (about 25 g protein, no powder)

Base recipe made with skyr instead of Greek yogurt and soy milk, plus diced mango, a spoon of desiccated coconut and lime zest.

Common problems and fixes

Meal prep: five jars on Sunday

1. Line up five jars or containers.
2. Add dry ingredients (oats, chia, seeds, cocoa, spices) to each.
3. Mix the wet ingredients in a large jug (yogurt, milk, powder, vanilla) and divide evenly.
4. Stir each jar well and seal.
5. Keep toppings separate and add each morning.

Use the meal prep recipe scaler to multiply the base for any number of days, and the protein cost calculator to see what each jar costs. The 7-day high-protein meal prep plan uses overnight oats on several days.

How much protein do you need at breakfast?

There's no single right number. Public health guidance such as the US Dietary Guidelines sets an adult minimum (the RDA) of 0.8 g of protein per kilogram of body weight per day, and many active people eat more. Spreading protein across meals rather than loading it all into dinner is a common, sensible approach, and 20 to 40 g at breakfast is a typical range in sports nutrition writing. If you have a specific goal or a medical condition, a registered dietitian can give you a number that fits you.

What overnight oats do well is make that 20 to 40 g easy on busy mornings. The base recipe already lands near 20 g; adding one booster gets most people into the high 20s without powder.

Warm "overnight" oats

Prefer a hot breakfast? Make the jar as usual, then microwave it in 30-second bursts, stirring each time, until warm through. The yogurt can separate a little when heated, so stir in an extra spoon of cold yogurt at the end for creaminess. Or skip the soak entirely: simmer the oats with milk for four minutes, take the pan off the heat, and stir in the yogurt and protein powder last.

Steel-cut, quick or rolled oats?

Rolled (old-fashioned) oats are best. Quick oats go soft and mushy overnight. Steel-cut oats stay quite chewy unless you soak them for a full 12 hours or more. Protein content is similar across types per gram.

Overnight oats for hiking

For the trail, pre-mix oats, milk powder, chia, protein powder and freeze-dried fruit at home in a zip bag. At camp, add cold water to the bag the evening before, or just before breakfast for "instant" soaked oats, and eat from the bag. A 100 g dry mix with milk powder and protein powder gives roughly 30 g of protein and about 420 kcal. More ideas in backpacking breakfast ideas.

Dietary notes

Oats are naturally gluten-free but often processed alongside wheat; buy certified gluten-free oats if you need them. For dairy-free oats, use soy milk, a high-protein plant yogurt and a plant protein powder, and check labels, because many plant yogurts are low in protein. This is general information, not personal dietary advice.
