Protein Overnight Oats are an easy, high-protein breakfast with 27 grams of protein per serving. Stir them together, and they’re ready to eat the next day, without cooking.
If you’re into meal prepping but are not a fan of traditional protein powder, you will love this recipe. These high-protein overnight oats are easy to prep and don’t taste like protein powder.
Instead, this recipe tastes like lightly sweetened oatmeal, with 27 grams of protein per serving. (And 10 grams of fiber to help keep you feeling full!)
Ingredients You’ll Need
This recipe starts with old-fashioned rolled oats, chia seeds (for extra fiber and protein), and your favorite milk. For the highest protein content, use cow’s milk or soy milk for a dairy-free option.
Non-dairy milk options like oat milk, coconut milk, or unsweetened almond milk will also work, but provide less protein.
Not a fan of collagen?
For a similar protein boost, you can replace it with 1/3 cup of plain Greek yogurt. You can also experiment with other options, like whey protein powder or chocolate protein powder.
(Note: I do not recommend my usual protein powder for this. It’s not delicious.)
Instead of calling for vanilla protein powder, this recipe relies on unflavored collagen peptides for added protein.
This blends seamlessly into the oatmeal, especially when you pair it with peanut butter and a touch of maple syrup for sweetness.
Make Protein Overnight Oats
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).
Add the oats, chia seeds, collagen powder, peanut butter, maple syrup, and milk to each jar. Stir well until the peanut butter has dissolved in the milk and no clumps are visible.
Secure the lid and store the jar(s) in the fridge to chill for at least 4 hours, or overnight.
When you’re ready to eat the oats the next day, 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.
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.
Gluten Free Tip
While oats are naturally gluten-free, they can be contaminated during processing. If necessary, shop for certified gluten-free oats.

- ½ cup old-fashined rolled oats
- 2 tablespoons collagen peptides
- 1 tablespoon chia seeds
- 1 tablespoon peanut butter
- 1 tablespoon maple syrup
- ¾ cup milk (see notes)
-
Add the rolled oats, collagen, chia seeds, peanut butter, 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.
Milk Note: Soy and cow’s milk have roughly 8 grams of protein per cup. This batch might have less protein if you swap for a dairy-free milk, like almond or oat milk.
Gluten-Free Note: Oats are naturally gluten-free, but can be contaminated during processing. Shop for certified gluten-free oats, if needed.
Protein Powder Note: I use unflavored collagen peptides in this recipe because you can’t taste this amount at all. (At least, not with peanut butter and maple syrup added.) Feel free to experiment with using your favorite protein powder instead. I tried adding 1 tablespoon of my usual unsweetened plant protein powder, and I hated it. So, experiment at your own risk.
