Ingredients & Substitutions

These are the main ingredients and substitutions for high protein overnight oats. Scroll below to the recipe card for full ingredients list and instructions.

Use old fashioned oats instead of instant oats. They soak up more liquid and become soft. Use gluten free oats for gluten free. Do not use quick oats.

Any type of milk works. For dairy free, use dairy free milk. For nut free, use cow’s milk, oat milk or coconut milk.

Chia seeds add a nutritional boost and soak up the milk. They are heart healthy, full of fiber and omega 3s. They can be omitted if needed, but the oats might not be quite as thick.

A little cinnamon adds a touch of flavor. Feel free to replace with a pinch of nutmeg.

Pure maple syrup sweetens these protein overnight oats. Honey or date syrup can be used in its place.

Any type of protein powder works. Use a plant based protein to make vegan overnight oats. Otherwise, feel free to use whey protein or collagen powder. Use vanilla or chocolate.

Expert Tips & Tricks

Use old fashioned rolled oats for best results. Instant oats are more rough and do not soak up the liquid as much. Do not use steel cut oats.

If needed, use certified gluten free oats.

Refrigerate for at least 4 hours. The longer it chills, the more creamy and soft the oats will become. These are great for meal prep and planning ahead!

Add toppings! This recipe is a great starting point for all the toppings. Stir in some nut butter, chocolate chips or nuts.

This recipe is also great topped with fruit or yogurt.

If protein overnight oats are too thick, feel free to add a splash more milk until desired consistency is reached.
