Ingredients for High-Protein Overnight Oats
- Oats – I recommend using old-fashioned rolled oats but quick-cooking oats will also work well. Do not use instant oats (i.e. pre-cooked oats) or steel-cut oats, they will not absorb as much liquid or provide as good of a texture.
- Chia Seeds – To thicken the overnight oats, create a rich and creamy texture, and add some healthy fats and a bit of protein at the same time.
- Protein Powder – The recipe calls for vanilla protein powder, but you can use any flavor your like. Be sure to use the best protein powder possible.
- Greek Yogurt – To add a big boost of protein and help to creamy a creamy texture. You can use whole milk or non-fat Greek yogurt. You can use plain yogurt; however, it won’t be as high in protein.
- Milk – Using cow’s milk helps to add additional protein to the oats. Although you can use almond milk or non-dairy milk, they will not provide nearly as much protein.
- Berries – To add some extra flavor and fiber. You can use fresh berries or fresh fruit of your choice.
Although optional, you can add a spoonful of honey or maple syrup to sweeten the protein overnight oats if you like. Depending on the flavor and sweetness of your protein powder you may or may not need it.
Dietary Adaptions
To Make them Gluten-Free: No adaptations are needed, this recipe is gluten-free. Just be sure to use certified gluten-free rolled oats.
To Make them Dairy-Free: You can make this recipe dairy-free by swapping the cow’s milk for unsweetened almond milk, soy milk, or coconut milk, and swapping the Greek yogurt for dairy-free yogurt, such as coconut milk yogurt, however, the oats will not be as high in protein.
