If you’ve been trying to eat more high-protein and high-fiber breakfasts lately, you might be sick of eating eggs. (I know I am.) That’s why I decided to revisit my classic overnight oats recipe and give it a higher-protein makeover.
First, I tried adding both peanut butter and collagen peptides. The collagen doesn’t add a yucky flavor like unsweetened protein powder often does. (And I don’t use zero-calorie sweeteners, so flavored ones are out, too.)
After a few more rounds of experimenting, I realized that my favorite way to make this relies on Greek yogurt for extra protein. It’s lower in calories and higher in protein than peanut butter, and it makes these oats taste like cheesecake. When you add fresh berries on top, it’s a delicious way to start your morning. Plus, you can eat it straight from the fridge with no extra effort on a busy morning.
With this Greek yogurt variation, you’ll get up to 29 grams of protein and 9 grams of fiber per serving, before you add any toppings. I’ll share the peanut butter version in the recipe notes, in case you prefer a dairy-free option, too.

High-Protein Overnight Oats Ingredients
- Old Fashioned Rolled Oats. You’ll get the best texture with old-fashioned rolled oats, since they don’t turn as mushy when soaked overnight. However, quick oats will work, too! If you need a gluten-free recipe, be sure to buy a package labeled “certified gluten-free.”
- Greek Yogurt. This adds tangy flavor, creamy texture, and protein. I usually buy the 3.5% milkfat kind, but I think low-fat or fat-free yogurt would also work here. (Or try dairy-free yogurt if you prefer.)
- Collagen Peptides. I use this as an unflavored protein “boost.” You can’t taste it at all in the final oatmeal, unlike regular protein powder. (I tried adding just 1 tablespoons of my plain protein powder to this and I couldn’t stand the flavor.)
- Milk of Choice. It doesn’t matter which kind of milk you use when it comes to soaking the oats, but certain varieties (like cow’s milk and soy milk) will have more protein than others.
- Maple Syrup. This is my natural sweetener of choice, and you definitely don’t need more than 1 tablespoon per serving. I use a little less than that when I plan on serving this with berries, since they are sweet, too.
- Chia Seeds. This helps the pudding thicken and adds fiber to help keep you feeling full.

How to Make Protein Overnight Oats
Step 1:
Start with a wide-mouth jar with a lid at least 12 ounces or larger. If you want to make multiple servings, use multiple jars (like a mason jar or working jar—see my favorite above).
To each jar, add 1/2 cup rolled oats, 1 tablespoon of chia seeds, 2 tablespoons of collagen powder, 1/3 cup Greek yogurt, 1 tablespoon of maple syrup, and 1/2 cup of milk to each jar. Stir well until no clumps are visible.

The texture will look runny at this point, but don’t worry, it will thicken up overnight!

Step 2:
Secure the lid and store the jar(s) in the fridge to chill overnight. If you’re in a hurry, they are usually tender enough to eat in 3 to 4 hours, so you could also make these in the morning for an easy lunch.
When you’re ready to eat the oats, grab a jar from the fridge and remove the lid. Stir well and add any toppings you like, such as sliced bananas, almonds, or fresh berries. I really love cheesecake with berries, so that’s my favorite topping.
Storage Tip: These jars can be stored in the fridge for 3 to 4 days, so make as many as you’d like to eat in that time.


Protein Overnight Oats (Tastes like Cheesecake!)
Ingredients
- ½ cup old-fashined rolled oats
- 2 tablespoons collagen peptides
- 1 tablespoon chia seeds
- ⅓ cup Greek yogurt
- 1 tablespoon maple syrup
- ½ cup milk (see notes)
Instructions
- Add the rolled oats, collagen, chia seeds, Greek yogurt, maple syrup, and milk to a 12-ounce or larger jar with a lid. Stir well until everything is mixed, then secure the lid and transfer to the fridge to chill. (At least 4 hours, or overnight.)
- When you're ready to eat, remove the lid and give the oats another stir. You'll notice that they have plumped up and absorbed the liquid. They are ready to eat with any toppings you like, such as fresh berries or a dollop of Greek yogurt.
- These jars can be stored in the fridge for 3 to 4 days, so you can make as many servings as you'll eat in that time.

My husband and I both thoroughly enjoyed these overnight oats. The creamy texture and the combination of flavors were delightful. The recipe was not only simple to follow but also allowed for some creativity with toppings. I will definitely be making these again, perhaps experimenting with different fruits and nuts to keep things interesting. Overall, a delicious and nutritious breakfast option!
