Bring soy milk and water to a gentle boil in a medium-sized pot.
Stir in oats, salt, cinnamon, and vanilla extract.
Lower the heat to medium-low and simmer for 20 minutes, stirring occasionally (every 5 minutes or so).
Add the protein powder and mix to combine with the oats.
Add more water, using just as much as you want to achieve your desired oatmeal consistency. I usually use about a ¼ cup, but you can use up to 1 cup more.
Continue simmering for about 5 minutes until the oats have reached your desired consistency.
Top with chopped strawberries, walnuts, and almond butter, and enjoy!
Notes
See more expert tips, pictures, and variations above for making the best protein steel-cut oats!Yield: 4 bowls of oatmeal, about 3 cups totalServing Size: 1 bowl of oatmeal, about ¾ cupStorage: Store leftover protein steel-cut oats in an airtight container in the refrigerator for 4 to 5 days. For longer storage, freeze individual servings in freezer-safe containers for 2 to 3 months. Reheating: When reheating on the stovetop, add milk or water to maintain creaminess. Alternatively, microwave them for a minute for a quick and easy preparation.Protein Content: Without the recommended toppings, the protein content of the oats alone is 20 grams. Each serving has ½ a scoop of protein powder. I find a full scoop to be too overpowering, but for an even higher protein content, you could double the amount of protein powder and add more water to maintain a creamy texture.
