High-protein overnight oats have become increasingly popular, and for good reason. By combining protein-rich ingredients with fiber-packed oats, you create a breakfast that provides sustained energy release throughout your morning. The preparation takes just 5 minutes the night before, making it perfect for busy professionals and fitness enthusiasts. Plus, 20-25g of protein per serving is an excellent option for meeting your daily protein goals.
Why This Recipe Works
Choosing the Right Ingredients
Best Protein Sources
The key to high-protein overnight oats lies in selecting the right protein sources. Greek yogurt serves as an excellent base, providing 15-20g of protein per serving while adding a creamy texture. For additional protein, you can incorporate:
- Protein powder (whey, pea, or hemp)
- Chia seeds
- Hemp hearts
- Nuts and nut butter
- Cottage cheese
Base Ingredients
Select old-fashioned rolled oats for optimal texture. These oats absorb liquid perfectly overnight without becoming mushy. While quick oats can work, they often result in a softer consistency. Steel-cut oats aren’t recommended for overnight soaking as they remain too firm.


Ingredients & Prep
Essential Components
Basic Recipe (1 serving):
- 1/2 cup old-fashioned rolled oats
- 1 scoop (30g) protein powder
- 1/2 cup Greek yogurt
- 3/4 cup milk (dairy or plant-based)
- 1 tablespoon chia seeds
- 1 tablespoon honey or maple syrup
- Pinch of salt
This combination provides approximately:
- Protein: 25g
- Fiber: 8g
- Healthy fats: 9g
- Complex carbohydrates: 45g
Preparation Method
The beauty of overnight oats lies in their simplicity. Combine all ingredients in a mason jar or container, ensuring the protein powder is fully incorporated. Seal tightly and refrigerate overnight or for at least 6 hours. The oats will soften and the chia seeds will expand, creating a thick, pudding-like consistency.
Step-by-Step Instructions
Pre-Prep Steps
- Gather all ingredients and measuring tools
- Choose a container with a tight-fitting lid
- Ensure protein powder is fresh and clump-free
- Check that your oats aren’t expired
Assembly Method
- Add dry ingredients first (oats, protein powder, chia seeds)
- Pour in milk and yogurt
- Add sweetener and any additional flavoring
- Stir thoroughly until well combined
- Seal the container and refrigerate
Storage Tips
Properly prepared overnight oats last 4-5 days in the refrigerator. Keep them in airtight containers and add fresh toppings just before serving. If meal prepping for the week, consider preparing all dry ingredients in advance.
