Recipe tips
Here are my top tips for making the best protein oatmeal:
- Stir often: This will prevent the oats from sticking while they cook.
- Remove from heat: After adding the protein, remove from the heat for the best consistency.
- Thicken the oatmeal: To make it even thicker, add some chia or flax seeds.
- Add more flavour: Try adding in maple syrup, brown sugar, honey or pumpkin pie spice.
Frequently asked questions
What’s the best kind of protein powder to use?
You can use whey, soy, rice or pea protein powder. I prefer whey protein, and this is the one I use if you’re looking for ideas.
Can I add protein in other ways?
You can add even more protein to your oatmeal by adding in some Greek yogurt, cottage cheese, nuts, seeds, or nut butter.
Can I make it in the microwave instead?
I haven’t tested it, but you can try. Add the milk and oatmeal to a microwave-safe bowl and microwave for 90 seconds to 2 mins.
Why is my protein oatmeal clumpy?
If you find that your oatmeal is clumpy, try removing the oatmeal from the heat and letting it cool a little bit before adding the protein powder.
