Overnight oats are the breakfast you make in five minutes the night before and eat straight from the fridge. The usual versions are mostly carbs, though. This one uses Greek yogurt and chia seeds to bring the base to about 26 g of protein per jar, before any protein powder.
Below you’ll find the base recipe, four flavors to keep it interesting through the week, and the macros for each.
Why this version works
- Greek yogurt does the heavy lifting. It adds around 15 g of protein per serving and makes the oats creamy instead of watery.
- Chia seeds thicken it overnight and add fiber, so the jar keeps you full until lunch.
- A pinch of salt sounds odd but makes the oats taste noticeably better, especially in sweet flavors.
- No cooking, no blender. Everything goes into one jar.
The base recipe (1 serving)
| Ingredient | Metric | US |
|---|---|---|
| Rolled oats | 40 g | ½ cup |
| Plain Greek yogurt (non-fat or 2%) | 150 g | ⅔ cup |
| Milk (dairy or soy) | 120 ml | ½ cup |
| Chia seeds | 12 g | 1 tbsp |
| Salt | A pinch | A pinch |
| Honey or maple syrup (optional) | 1 tsp | 1 tsp |
Method
- Add the oats, chia seeds and salt to a jar or container with a lid.
- Add the yogurt, milk and honey, if using. Stir well, scraping the bottom so no dry oats are left.
- Stir in the flavor ingredients from one of the options below, except fresh fruit toppings.
- Cover and refrigerate for at least 4 hours, or overnight.
- In the morning, stir, loosen with a splash of milk if it’s too thick, and add any fresh toppings.
Use rolled oats, not instant oats (they turn mushy) or steel-cut oats (they stay too hard without cooking).
4 flavors
Add these to the base recipe.
1. Peanut butter banana
Stir in 1 tbsp (16 g) peanut butter. In the morning, top with half a small banana, sliced. This is the most filling of the four and works well before a morning workout.
2. Berry vanilla
Stir in ¼ tsp vanilla extract. Top with 75 g (½ cup) mixed berries, fresh or frozen. Frozen berries can go in the night before; they thaw into a jammy layer by morning.
3. Chocolate protein
Stir in 15 g (half a scoop) chocolate or vanilla protein powder, 1 tbsp unsweetened cocoa powder and an extra 30 ml (2 tbsp) milk, since the powder thickens the mix. This is the highest-protein option.
4. Mango cardamom
Stir in a pinch of ground cardamom. Top with 75 g (½ cup) diced mango and 1 tbsp chopped pistachios. A nod to Indian mango lassi, and very good with frozen mango in winter.
Macros per jar
Values are approximate, calculated from USDA FoodData Central using non-fat Greek yogurt, 2% dairy milk and no honey. Add about 20 calories and 6 g carbs if you use 1 tsp honey.
| Flavor | Calories | Protein | Carbs | Fat | Fiber |
|---|---|---|---|---|---|
| Base only | 357 | 26 g | 43 g | 9 g | 8 g |
| Peanut butter banana | 496 | 30.5 g | 58 g | 17.5 g | 10 g |
| Berry vanilla | 397 | 26.5 g | 53 g | 9.5 g | 10.5 g |
| Chocolate protein | 444 | 40 g | 49 g | 11.5 g | 10 g |
| Mango cardamom | 447 | 28 g | 56.5 g | 13 g | 10 g |
Protein with and without powder
You don’t need protein powder for a high-protein breakfast. The base already gives about 26 g, which is a solid serving for most people.
If you need more, there are three easy ways to raise it:
- Add half a scoop of protein powder (about +12 g), as in the chocolate version.
- Use 200 g Greek yogurt instead of 150 g (about +5 g).
- Swap regular Greek yogurt for skyr or high-protein yogurt, which can add 3 to 5 g more per serving depending on the brand.
For a dairy-free version, use soy yogurt and soy milk. Most plant yogurts contain much less protein than Greek yogurt, so add protein powder to keep the total high.
How long do overnight oats keep?
Stored in a sealed container in the fridge, overnight oats keep for up to 4 days. That makes them easy to prep on Sunday for most of the working week.
- Keep the fridge at 4°C (40°F) or below, since the recipe contains dairy.
- Add fresh fruit, nuts and banana on the morning you eat them; they go soft or brown if added days ahead.
- Frozen berries and frozen mango are the exception and can go in the night before.
- Don’t freeze finished overnight oats; the yogurt texture turns grainy when thawed.
Troubleshooting
| Problem | Fix |
|---|---|
| Too thick in the morning | Stir in 1 to 2 tbsp milk before eating. Protein powder and chia both absorb liquid. |
| Too runny | Use thicker Greek yogurt, add another teaspoon of chia, or give it a few more hours in the fridge. |
| Too sour | Greek yogurt is tangy. Add vanilla, a little honey, or more fruit. |
| Mushy texture | You probably used quick or instant oats. Switch to rolled oats. |
| Dry oats at the bottom | Stir the jar well before refrigerating, scraping the corners. |
Common questions
Can you eat overnight oats warm? Yes. Microwave for 1 to 2 minutes, stirring halfway, and add a splash of milk. Add protein powder after heating if you can, since some powders go lumpy when heated.
Are overnight oats good for weight loss? They can be. The high protein and fiber keep you full, which helps you eat less later. Keep an eye on high-calorie toppings like nut butter and honey.
Are overnight oats gluten-free? Oats are naturally gluten-free but are often processed alongside wheat. If you need to avoid gluten, buy oats labeled certified gluten-free.
Can I use water instead of milk? You can, but the oats will be less creamy and you’ll lose about 4 g of protein per jar.
Make it your own
Once you know the base ratio, the flavors are endless: apple and cinnamon, coffee and cocoa, coconut and pineapple. Keep the oats, yogurt, milk and chia the same, change the flavorings, and you’ll always end up with a high-protein breakfast ready when you wake up.
