    Why this baked protein recipe is the best!

    This protein oatmeal is such a warm and satisfying breakfast. This can be mixed up in 10 minutes and bake while your getting ready on busy mornings.  It has a sweet vanilla flavor with a hint of cinnamon similar to a cinnamon roll but without the guilt!  Top this with a drizzle of maple syrup or agave syrup with a few berries for a special breakfast treat!

    Key ingredients

    old fashioned rolled oats- are oats that have been minimally processed.  They will soften more than steel cut oats and hold their texture better than quick oats.  Oats are a great source of whole grains.  There are many amazing health benefits to eating oats.  They help manage your weight and reduces blood sugar levels.

    protein powder- there are many different types of protein powder to choose from.  There are plant based or whey options and they will vary in the nutritional content.   They make a lower sugar option as well as low calorie and low carb.  Choose a vanilla flavored protein that works for your needs.  Check out my favorite protein powder.

    almond milk- any variety of milk will work just remember it will change the nutritional information a little.

    almond butter- use your favorite nut butter.  I like the subtle flavor that natural almond butter adds to the baked oats.

    coconut oil- this helps bind everything together. You could use avocado oil or any oil you prefer.

    ingredients needed for protein baked oats.

    step-by-step instructions

    In a large mixing bowl mix together vanilla protein powder, oats, cinnamon and salt.

    mixing the dry ingredients.

    In another large bowl mix together the wet ingredients of almond milk, apple sauce, almond butter, vanilla extract, egg whites, maple syrup, and coconut oil.

    mixing the wet ingredients.

    Stir together the wet and dry ingredients coating the oats in the milk mixture.

    A mixing bowl with the wet ingredients stirred into the oats.

    Pour the oatmeal mixture into a baking dish.  Bake in 350 degree oven for 35 minutes.  It will be very runny but that is okay, the oats will absorb the liquid while baking.

    Expert Tips

    • The mixture will seem very liquidy but the oats and the protein will absorb the liquid.
    • Choose a protein you like the flavor of because this will give the overall flavor of the oatmeal recipe.
    • If the protein powder you choose isn’t very sweet you can add an additional tablespoon of maple syrup to sweeten the recipe.

    Serving suggestions

    Baked oatmeal is best served warm with a little extra maple syrup drizzled over top. You can add fresh fruit or berries with a sprinkle of cinnamon.  My husband likes to add an extra splash of milk to his.

    Can I Make ahead

    The best part of baked oatmeal is that it's an easy high protein recipe that is great for meal prep!  Bake this on Sunday to have for the next few days.  Allow to cool completely before refrigerating.  Store in an airtight container until the next morning.  To reheat cut a piece and warm in the microwave for 45-60 seconds or until it is warmed through.  Kept in the refrigerator baked oatmeal will be fresh for 3-5 days.

    Storing and freezing tips

    For best results, allow the oatmeal to cool completely before freezing.  You can either bake and then freeze the entire baking dish or you can cut into single serving pieces and wrap individually.  Use plastic wrap and tightly wrap the baked oatmeal and put the pieces inside a freezer bag.  They will keep in the freezer for up to 3 months.

    Can I make this gluten-free?

    Yes, make sure that you buy certified gluten-free oats and a gluten-free protein powder.

      I see the ingredients photo shows applesauce, but it’s not on the ingredient list. How much applesauce do you need for this recipe?

      This recipe is delicious and perfect for breakfast!! We LOVE this recipe and we'll always make it! Thank you SOOO much. We feel so blessed! I lift weights and I do a 100g + a day animal protein diet, but a recent hospital event made me re-evaluate my breakfast choices. hehe I had enough of the low protein cold oats, making me gain weight. I can't thank you enough for this!!!!

          Can I substitute bananas in place of applesauce or egg whites?

            You can definitely use bananas in place of the applesauce. I'm not sure without testing the recipe if the egg white can be replaced but I think it would probably work.

        You could mash a banana, it would change the flavor but I'm sure would still be good.

          Would oat milk be a suitable alternative for this?
