🌿 Ingredients

Ingredients for protein overnight oats arranged on a marble countertop.

The ingredients for this overnight oats recipe are all easily found at large grocery stores. The berries are totally optional; you can also top with sliced bananas, strawberries or your other favorite fruits. I like using Vega Protein Made Simple Vanilla (affiliate link) protein powder since it contains natural ingredients, but feel free to substitute any protein powder you like (chocolate is delicious too!)

Here are a few other ingredient notes:

  • Rolled oats - you'll definitely want to use old fashioned for this recipe as quick cooking oats do not stand up well and tend to get too mushy overnight (if you have celiac disease or gluten sensitivity, make sure to use certified gluten-free oats to avoid cross contamination issues with wheat)
  • Chia seeds - substitute ground flax seeds or just leave out if you don't have either (note that they do help thicken the oats, so you may want to use a little less milk if you're not using chia or flax)
  • Maple syrup - you can substitute coconut sugar or honey
  • Soy milk - feel free to use any other non-dairy milk such as almond milk, oat milk or coconut milk, or substitute dairy milk

See recipe card below for exact quantities.

📝 Instructions

Rolled oats, chia seeds, protein powder and maple syrup in a glass working jar.

Step 1: Place the oats, chia seeds, protein powder, syrup and sea salt in a small jar.

Step 2: Pour in the milk and stir well to incorporate everything together.

Pro tip: Just like with warm oatmeal, you can adjust the amount of milk you add to your overnight oats to make them the perfect texture for you. As written, this recipe will yield slightly wet overnight oats, but feel free to cut back on the amount of milk if you like your oats to have a little less liquid.

Step 3: Wash and add some fresh berries on top of your oats if desired, place the lid on your jar and refrigerate overnight.

Step 4: In the morning, mix the fresh berries in a little and enjoy! If you prefer warmer oats, heat the oats in the microwave for 30-60 seconds or to desired temp.

📖 Variations

There are so many delicious ways you can mix up this overnight oats recipe. Here are few of my favorites:

  • Chocolate protein overnight oats - use chocolate protein powder instead of vanilla
  • Peanut butter protein overnight oats - add a tablespoon of peanut butter when you mix everything together, or try this peanut butter overnight oats recipe to make without protein powder
  • Protein overnight oats without protein powder - substitute a tablespoon or more more of almond butter or other nut butter (or chopped nuts) for the protein powder, and use soy milk for the plant milk since it contains more protein than other plant-based milks
  • Overnight oats with whey protein - substitute vanilla or chocolate whey protein powder (but keep in mind it will no longer be vegan or dairy free)

💭 FAQ

How much protein powder should I add to make protein overnight oats?

One scoop of vanilla or chocolate protein powder is a good rule of thumb to make protein overnight oats, which will yield about 15-25 grams of extra protein per serving.

How can I make my overnight oats thicker or thinner?

You can adjust the amount of milk to make your oats wetter or drier, and you can also add chia seeds, ground flax seeds or a little Greek yogurt to thicken the consistency.

What kind of milk works best for protein overnight oats?

Soy milk or dairy milk will yield more protein in addition to the added protein powder, but any plant milk such as almond milk will work as well.

What can I add to overnight oats with protein powder?

Fresh berries such as blueberries, raspberries or blackberries work well over protein overnight oats, as well as sliced bananas and strawberries, sliced kiwi or other fresh fruits.

Storage: Overnight oats will stay fresh in the fridge for up to 4 days and work well for meal prep if you'd like to make ahead for the week. They don't stand up well to freezing.
