I love me some overnight oatmeal. They are a godsend in the summer when the last thing you want is a hot breakfast. You can make them in a bunch of different flavors, too.

Why you will love this recipe
Let’s talk fiber and protein, shall we? From my recipe analytics, I have noticed that people are on the hunt for breakfasts with high protein and fiber, so this recipe is for YOU. This recipe has 24 grams of protein and 5 grams of fiber, making it a great source of both.
Easy, peasy, lemon squeezy. All you have to do is measure and stir, then let it cold soak in the fridge overnight. Done. This is perfect for healthy meal prep.
This recipe is also naturally gluten-free. Bonus!

Ingredients
Find the complete ingredient list, with measurements, in the recipe card below.
- Oats – Old-fashioned rolled oats are the way to go with this recipe. Quick oats can tend to get mushy, so we always opt for the rolled. I grab a big bag of sprouted grain rolled oats at Costco and use it in a ton of recipes. They are certified gluten-free oats.
- Protein Powder – My pick is Ora brand “So Lean So Clean” in vanilla. It has a great nutrition profile with no weird ingredients.
- Chia Seeds – These are a great add-in for a little more fiber and a boost of omega-3s.
- Milk – This helps to soften the oats while they soak, and provides extra protein.
- Greek Yogurt – For a creamy, delicious way to add protein to this breakfast. We love our local Tree Island Greek yogurt. It is the BEST.
- Maple Syrup – Just a touch of natural sweetness. You could also use agave or honey as a natural sweetener.
- Blueberries – It is summer as I post this, so sweet and juicy fresh blueberries are in abundance. You can use frozen blueberries, but just be ready for your oats to turn blue as they release juice as they thaw. They still will taste yummy! They will just have a touch of the Violet Beauregard, if you know what I mean. 😉
- Salt – We use a fine sea salt in all of our recipes.
Expert Tip!
Even sweet oats taste best with a pinch of salt. It brings out the best in your ingredients and really makes the flavors pop.

Equipment
Nothing fancy is required for this recipe.
- Mixing Bowl – I use a medium-sized mixing bowl so there is enough room to stir, but also enough room to place it in my fridge. We live in a small downtown apartment, so space is at a premium.
- Spoon or Spatula – This is for stirring your mixture. I love using a spatula for mixing as it really scrapes the sides down and gets every bit, which appeals to my meticulous nature.
- Wrap – This is to cover your bowl when you place it in the fridge. You can use a lid, plastic wrap, or beeswax wrap as long as it creates a tight seal.
- Includes 1.3-qt, 2.3-qt, and 4.5-qt round glass bowls with BPA-free lids.
- This Pyrex line is proudly designed and manufactured in the U.S.A.
Instructions

Step 1
First, add the dry ingredients to your mixing bowl. Give them a good stir.
Step 2
Next, add the wet ingredients and stir them in well to combine everything.
Step 3
Finally, gently fold in the blueberries.



Step 4
Then, cover the bowl tightly with the wrap. Place the bowl in the refrigerator overnight (or at least 4 hours) for the oats to soften up and create a creamy, perfect consistency.
Step 5
In the morning, portion your oats into two bowls, add your favorite toppings, and enjoy.

Substitutions and recipe variations
Instead of regular whole milk, you can use unsweetened almond milk, hemp milk, oat milk, or coconut milk.
To make this vegan, swap in coconut yogurt instead of Greek yogurt.
Feel like chocolate for breakfast? Sprinkle in some cacao powder with your dry ingredients.
Serving suggestions
For me, overnight oats are all about the toppings. I like to add peanut butter granola to give a bit of crunch to balance the creamy nature of the oats. Other toppings include fresh berries, sliced bananas, hemp seeds, chia seeds, nut butter, and chopped nuts.
Swirl in some blueberry chia jam for an extra punch of blueberry goodness. Or add strawberry chia jam for a very berry experience.
FAQS
The longer the better, hence the name ‘overnight’. Overnight is best for texture, but a bare minimum of four hours.
Yes, you can. A quick 30-60 seconds in the microwave or on the stovetop with a splash of extra liquid if you prefer warm oats.
Storage tips
Store your overnight oats tightly wrapped or in an airtight container. They will keep if properly stored in the fridge for up to 3 days.
