Ingredients (per serving):
- 1/2 cup (40g) rolled oats (old-fashioned, not instant)
- 1 scoop (30g) protein powder (vanilla or chocolate work well)
- 1/2 cup (120ml) milk of your choice (dairy or non-dairy)
- 1/2 cup (125g) plain Greek yogurt
- 1 tablespoon (10g) chia seeds
- Optional: 1-2 teaspoons of sweetener like maple syrup or honey, if needed

- Protein: 35-40g
- Carbohydrates: 40-45g
- Fat: 10-12g
The Method
This is less of a recipe and more of an assembly process. All you need is a jar with a lid or a small container.
- Combine Dry Ingredients: In your jar, add the rolled oats, protein powder, and chia seeds. Put the lid on and give it a good shake to mix everything together. This prevents the protein powder from clumping.
- Add Wet Ingredients: Remove the lid and add the milk, Greek yogurt, and any optional sweetener.
- Mix Thoroughly: Use a spoon to stir everything together until it's well combined and there are no dry pockets. Make sure to scrape the bottom of the jar.
- Refrigerate: Secure the lid and place the jar in the refrigerator for at least 4 hours, but preferably overnight. The oats and chia seeds will absorb the liquid, soften, and create a creamy, pudding-like texture.
- Serve: In the morning, give it a quick stir. You can eat it straight from the jar or transfer it to a bowl. Add your favorite toppings and enjoy.
Customization and Toppings
This is where you can get creative. Mix and match these additions to keep your breakfast interesting.
- Fruit: Add fresh berries, sliced banana, or diced mango on top just before serving.
- Nuts and Seeds: A sprinkle of chopped almonds, walnuts, or pumpkin seeds adds a great crunch and healthy fats.
- Spices: A dash of cinnamon, nutmeg, or cardamom in the base mix adds a lot of flavor.
- Flavor Extracts: A few drops of vanilla or almond extract can enhance the taste.
- For a thicker texture: Use slightly less milk. For a thinner texture, add a splash more in the morning.
Frequently Asked Questions (FAQ)
Can I use steel-cut oats?
Steel-cut oats require more liquid and a longer soaking time, and they will have a much chewier texture. Rolled oats are generally recommended for the best creamy consistency.
Can I heat it up?
Yes. You can microwave your overnight oats for 60-90 seconds if you prefer a warm breakfast. You may need to add a splash of milk before heating.
What kind of protein powder is best?
Both whey and casein protein work well. Casein tends to create a thicker, creamier texture. Plant-based protein powders also work, but they can be more absorbent, so you might need to add a little extra liquid.
