Substitutions
Here are my recommended substitutions to make this overnight oats with protein if you need them.
- Oats: Heartier types of oats such as old fashioned, rolled oats or steel cut oats are better options for overnight oats. Quick cooking oats will become mushier than the other types of oats. If needed, use gluten free oats to make these overnight protein oats gluten free.
- Chia Seeds: I like adding chia seeds to overnight oats for a thicker and creamier consistency. Feel free to omit or use flax seeds if you like.
- Milk: Use any milk you like. Plant based milk also works well in this recipe if you would like to make these protein overnight oats vegan. For an extra boost of protein, use protein milk.
- Yogurt: Use a good greek yogurt you like. If you would like to make this vegan, use a plant based yogurt.
- Protein Powder: Use your preferred vanilla or chocolate protein powder. I personally love this one.
- Maple Syrup: Honey or agave work well to sweeten these protein oats.

M’s Expert Tips
- Mix the ingredients directly into individual containers. The easiest and more precise way to make overnight oats is to mix the dry and wet ingredients directly into the individual containers.
- Max out on protein. For the most protein, use a combination of greek yogurt, protein milk and a scoop of protein powder for the base of the overnight oats. Add some nut butter for even more protein.
- Use the right kind of oats. Rolled oats, old fashioned oats or steel cut oats are good for making overnight oats. Quick cooking oats are not ideal unless you prefer a mushier texture.
- Add chia or flax seeds. The addition of chia or flax seeds adds healthy omega-3 fats and creates a thicker more pudding like consistency to the overnight oats.
- Add toppings before serving. Add a dollop of lightly sweetened yogurt, fruit like berries, a drizzle of nut butter, chopped nuts and/or a dusting of cinnamon right before serving.
