How to Make Protein Baked Oatmeal

Step 1: Prep Your Oven and Baking Dish

Begin by preheating your oven to 375°F. Lightly spray an 8-inch square baking dish with nonstick cooking spray to ensure your bake comes out effortlessly later. This step is small but so important—no one wants to wrestle with stuck oatmeal in the morning!

Step 2: Mix Together the Base Ingredients

In a large mixing bowl, combine the rolled oats, vanilla protein powder, unsweetened almond milk, peanut butter, eggs (or flax eggs for a plant-based option), maple syrup, coconut oil, vanilla extract, and salt. Use a sturdy spoon or whisk to blend everything thoroughly. This mixture will look creamy and smell absolutely divine, hinting at the delicious breakfast to come.

Step 3: Fold in the Blueberries

Gently stir in the fresh blueberries, being careful not to smash them so they stay whole and juicy as they bake. The little pops of blueberry color will look gorgeous speckled throughout the oatmeal batter.

Step 4: Pour and Top

Carefully pour the oat mixture into your prepared baking dish, spreading it out evenly with a spatula. Sprinkle a few extra blueberries on top for good measure—this not only looks beautiful, but gives you bursts of berry flavor in every bite.

Step 5: Bake and Cool

Pop the dish in your preheated oven and bake for 35 to 40 minutes, or until the center is set and the top has become a lovely golden hue. Let the Protein Baked Oatmeal cool for several minutes before slicing, which helps everything firm up and makes serving slices a breeze.

Step 6: Portion and Serve with Nut Butter

Once slightly cooled, cut your oatmeal into squares, plate them up, and drizzle with your favorite nut butter. The warmth of the oatmeal makes the nut butter extra melty and irresistible.

How to Serve Protein Baked Oatmeal

Garnishes

Have fun with toppings! Try adding extra blueberries, a sprinkle of toasted nuts for crunch, a dusting of cinnamon, or a modest dollop of Greek yogurt for creaminess. Whatever you choose, each garnish transforms your Protein Baked Oatmeal into a showstopper.

Side Dishes

This bake is pretty satisfying all on its own, but you can round out the meal with a fresh fruit salad, crispy turkey bacon, or a smoothie for a brunch that really feels like a treat. Even a simple side of sliced bananas alongside your oatmeal squares can add a touch of natural sweetness.

Creative Ways to Present

For an eye-catching brunch spread, cut the Protein Baked Oatmeal into small squares and serve them stacked on a platter with little nut butter cups for dipping. Hosting a crowd? Try baking in mini ramekins for adorable individual servings. Don’t be afraid to play with presentation—this dish is as versatile as it is tasty.

Make Ahead and Storage

Storing Leftovers

Leftover Protein Baked Oatmeal keeps beautifully! Once cooled, store individual portions in an airtight container in the refrigerator. They’ll stay moist and delicious for up to five days, making breakfast a grab-and-go delight all week.

Freezing

To freeze, let the oatmeal cool completely, slice it into portions, and wrap each tightly in plastic wrap or parchment paper. Place wrapped squares in a freezer-safe bag or container. It keeps fresh for up to three months—just think of it as meal prep magic for future you!

Reheating

For the best results, reheat Protein Baked Oatmeal in the microwave for about 30–60 seconds per square, or warm in a 350°F oven for about 10 minutes. Add a splash of almond milk before reheating if you want things extra moist. Don’t forget the drizzle of nut butter before serving—it truly brings everything together.

FAQs

Can I use quick oats or steel cut oats instead of rolled oats?

Rolled oats are ideal because they give Protein Baked Oatmeal its perfect chewy texture. Quick oats would work in a pinch but may produce a softer, less hearty result. Steel cut oats are not recommended here, as they don’t soften enough with this baking time.

Is there a substitute for protein powder?

If you don’t have protein powder, you can add a bit more oats and a touch more sweetener to maintain structure and flavor. While you won’t get the protein boost, the bake will still be delicious and hearty.

Can I make Protein Baked Oatmeal vegan?

Absolutely! Swap in flax eggs for the regular eggs, and use a plant-based protein powder. Make sure the maple syrup and other ingredients are certified vegan as needed.

What other fruits can I use instead of blueberries?

Try swapping blueberries with raspberries, diced strawberries, or even chopped apples for a fun twist on classic Protein Baked Oatmeal. Dried cranberries or cherries also add delightful tartness if fresh fruit isn’t on hand.

Can Protein Baked Oatmeal be made nut free?

Yes! Use sunflower seed butter in place of peanut or nut butter and ensure your protein powder and milk of choice are nut free. The oatmeal stays just as rich and satisfying—perfect for sharing with everyone.
