High Protein Greek Yogurt Overnight Oats

High Protein Greek Yogurt Overnight Oats

Greek yogurt and vanilla protein powder make the no-cook oat base creamy, while rolled oats keep their shape as they soften. Whisk the powder into the milk first to avoid dry clumps, then let the oats and chia thicken in the refrigerator. Serve the oats cold in a bowl with fresh banana slices, whole blueberries, and a separate dollop of peanut butter. Because protein powders absorb liquid differently, check the texture after chilling and loosen the oats with a little milk if needed.

Ingredients

Makes 1 generous serving. Prep time: 10 minutes. Chill time: at least 4 hours, preferably overnight.

• 1/2 cup milk (120g), plus 1–3 tablespoons more if needed
• About 1/2 scoop vanilla protein powder (15g; scoop sizes vary)
• 1/2 cup plain Greek yogurt (120g)
• 1/2 cup old-fashioned rolled oats (40g)
• 1 tablespoon chia seeds (12g)
• 1/2 medium banana, sliced (about 60g)
• 1/3 cup fresh blueberries (about 50g)
• 1 tablespoon creamy peanut butter (16g)
• Optional: 1–2 teaspoons maple syrup, to taste

How to Make Greek Yogurt Overnight Oats

1. Whisk the powder: In a pint-size jar or other container with room to stir, whisk the 1/2 cup milk and protein powder until evenly combined, with no dry pockets.
2. Mix the base: Stir in the Greek yogurt, rolled oats, and chia seeds until no dry oats or chia clumps remain. Add maple syrup if needed for sweetness.
3. Cover and chill: Refrigerate for at least 4 hours, preferably overnight. The oats are ready when the flakes have softened but remain visible and the mixture is creamy and spoonable.
4. Adjust the texture: Stir well. If the oats are stiff, add milk 1 tablespoon at a time, up to about 3 tablespoons, until they mound softly on a spoon. Transfer to a serving bowl.
5. Add the toppings: Slice the banana and group the rounds along one side of the bowl. Cluster the whole blueberries toward the front and add a separate dollop of peanut butter, leaving some oats visible between the toppings. Serve cold.

How Thick Should Overnight Oats Be?

The oats should be moist and thick enough to mound gently, not dry or runny. Stir before adding milk; the top can look firmer than the mixture underneath. If the oats are still loose after 4 hours, stir and continue chilling until the flakes soften and the base thickens.

Old-fashioned rolled oats retain visible flakes and some chew. Quick oats soften faster and can become mushy, especially during longer storage.

Protein Powder and Milk Choices

Protein powders differ in sweetness, texture, and how much liquid they absorb. Whisking the powder into milk reduces clumps, but it cannot remove grittiness inherent to a powder. Wait until after chilling to decide whether the oats need extra milk.

For a powder-free version, omit the protein powder, begin with slightly less milk, and adjust after soaking. It will have less protein than the main version. Soy milk is a plant-milk option for a protein-forward bowl, though protein amounts vary by product.

Make-Ahead and Storage

Keep the covered oat base in the refrigerator and aim to eat it within 3 days for the best texture. A 5-day storage window is sometimes used, but the oats will continue to soften and thicken. Store the fruit separately; slice the banana and add it with the blueberries and peanut butter just before serving.

For another blueberry-forward bowl, try lemon blueberry overnight oats. For more banana and peanut butter flavor, see peanut butter banana overnight oats.
