How To Make Protein Baked Oatmeal
A protein baked oatmeal is like a classic baked oatmeal recipe but boosted with high-protein ingredients.
It’s the perfect post-workout breakfast if you want to build muscles or simply look for a fulfilling breakfast that is low in calories and high in fiber.
Ingredients
All you need to make a tasty protein baked oatmeal are:
- Almond Milk or any milk you love, but almond milk is low in calories and has low flavors, but still, adds creaminess to the oatmeal.
- Greek Yogurt – This is the best type of yogurt to boost the protein in baked oatmeal.
- Vanilla Protein Powder – I am using clean pea protein powder made with wholesome ingredients. It’s plant-based and gut-friendly. Feel free to use your favorite protein powder for this recipe.
- Maple Syrup – You can also use sugar-free maple syrup, agave syrup, or brown rice syrup.
- Peanut Butter – You need fresh drippy peanut butter, or it’s hard to whisk in. Other options are almond butter, cashew butter, tahini, or sunflower seed butter.
- Egg
- Egg White – This is optional but a great way to boost the protein content and increase the creaminess without adding tons of calories.
- Old-Fashioned Oats or quick oats
- Chia Seeds
- Mixed Berries – Like blueberries, raspberries, boysenberries, or strawberries.
- Cinnamon
Preparation
In a large bowl, add almond milk, Greek Yogurt, egg, maple syrup, peanut butter, and egg whites if used. Whisk until all the ingredients come together.
Next, whisk in the protein powder until no more lumps of powder can be seen.
Finally, stir in the remaining dry ingredients: rolled oats, chia seeds, and cinnamon.
If you like, fold in the mixed berries, fresh or frozen, and stir to combine evenly.
Preheat the oven to 350°F (180°C). Spray some cooking oil in a 8-inch x 8-inch square baking dish.
Pour the oatmeal into the dish and bake it on the center rack for 30 to 45 minutes or until the top is dry and the center set and not jiggly.
Flavoring Ideas
You can use these protein baked oats to create a range of baked oatmeal flavors.
For example, you can use different protein powder flavors, including chocolate protein powder, to make chocolate protein baked oats.
Other options consist of replacing the berries by a mix of:
- Carrot Cake – Grated carrots and chopped walnuts.
- Chocolate Baked Oats – Use chocolate protein powder and stir in chocolate chips instead of berries.
- Banana Bread Baked Oats – Replace the egg white with 1/3 cup of mashed banana and swap the berries for a mix of chopped roasted nuts – walnuts, pecans, and some dried raisins.
Serving
This protein oatmeal is delicious on its own but so much better with some toppings like:
- Drizzle of nut butter – cashew butter, peanut butter, or almond butter.
- Shredded coconut
- Hemp seeds for a boost of protein
- Drizzle of maple syrup to boost sweetness
- Fresh berries
- Drizzle of milk of choice
- Dollop of extra plain Greek yogurt
- Sliced almonds or chopped peanuts
Storage Instructions
The great thing about baked oatmeal recipes is that they can be stored for up to 5 days in the fridge.
Therefore, this protein baked oatmeal is the best healthy breakfast to meal prep a week of high-protein breakfast.
Store the baked oatmeal in its own baking dish and wrap the top with a piece of foil or plastic wrap.
Rewarming Baked Oatmeal
Some people enjoy cold baked oatmeal, but if you prefer yours warm, it’s very easy to do.
To rewarm it up, place one serve of baked oatmeal in a shallow, microwave-safe bowl and place in the microwave for 1 minute or until warm in the center.
You can also add the oatmeal to a non-stick saucepan with a bit of milk at the bottom, cover it, and rewarm on low heat until hot in the center.
Tips For Creamy Protein Baked Oatmeal
The main issue with protein powder recipes is their texture. Often, protein powder makes baked goods dry. So the trick to avoid that is to:
- Check The Baking Often – After 30 minutes, check the consistency. If the top is set and center of the dish not jiggly, you may want to stop baking the oatmeal. This keep the texture ultra moist and creamy. Bake by extra burst of 5-10 minutes until the texture match your liking
- Add Egg Whites – This makes a great difference! If you don’t eat eggs, try 1/3 cup of mashed banana or unsweetened applesauce. That won’t boost the protein content by increasing the moisture in the protein baked oats.
- Use Plant-Based Protein Powder – Whey protein powder absorbs liquid more, and often, it turns protein recipes drier.
Allergy Swaps
Below I listed some options to adapt the recipe to any food allergies you may have:
- Gluten-Free – Pick a gluten-free oat brand and wheat-free protein powder.
- Nut-Free – Use coconut milk, oat milk, or soy milk. Replace the peanut butter for sunflower seed butter, olive oil, or melted butter.
- Vegan – Swap the Greek yogurt for soy yogurt or plant-based yogurt you love. Swap the egg for a flax egg. See the recipe card notes below to learn how to make a flax egg. Skip the egg whites, and add 1/3 cup of mashed bananas instead.
- Dairy-Free – Use dairy-free yogurt.
- Sugar-Free – Use Monk fruit syrup and low-sugar fruits like raspberries. Pick a low-carb protein powder.
- Egg-Free – Replace the eggs with a flax egg – see notes below. Skip the egg white.
- Chia Seed-Free – Replace the chia seeds with a tablespoon of ground flaxseeds or an extra egg.
