A simple, homestyle blueberry oatmeal baked with crunchy walnuts, tangy berries, and softened oats. As we bake this sweet breakfast casserole, the top layer gets all crisp and toasty. This serves as a delicious, crunchy topping for those juicy berries at the bottom. We enjoy this baked blueberry oatmeal just as much for breakfast as we do for dessert!
How To Make This Recipe
This baked oatmeal recipe is loaded with wholesome ingredients, including old-fashioned oats, nuts, and blueberries. Old-fashioned oats, or rolled oats, hold up especially well in this dish because they handle moisture well. Instead of using eggs as a binder, we cut the cholesterol by using unsweetened applesauce.
We’ve used both fresh and blueberries successfully, so we recommend using whatever you have handy. While we’re using blueberries here, this recipe is quite flexible to accommodate whatever fruit you have on hand.
Prepare Oatmeal Topping
We start by pre-heating our oven to 350 degrees. While the oven pre-heats, we whisk together our dry ingredients in a medium bowl. This includes our oats, walnuts, baking powder, nutmeg, and salt.
Mix dry ingredients in a medium bowl.
Next, in a large bowl, we whisk together remaining wet ingredients. We include our melted non-dairy butter, non-dairy milk, applesauce, brown sugar substitute, and vanilla extract.
Whisk together wet ingredients.
Then, we bring our wet and dry ingredients together. We do so by pouring our dry oat mixture into the larger bowl of wet ingredients. Next, we mix until just combined using a spatula.
Combine wet and dry ingredients.
Assemble And Bake
Now, it’s time to assemble our baked oatmeal with blueberries. We start by greasing a standard 8×8-inch baking dish. Then, we scatter our blueberries in bottom of our prepared baking dish. We’re aiming for an even layer of berries.
Pour blueberries into prepared baking dish.
Next, we pour our topping over the berries. Finally, we shake the baking dish to evenly distribute the topping.
Pour oatmeal mixture over blueberries.
Let’s get to baking. We allow our oatmeal casserole to bake for 35 minutes or until our blueberry oatmeal baked firm and pale golden. Then, we remove our dish from oven.
Enjoy your blueberry baked oatmeal.
Ready To Serve
Before we dig in with our serving spoons, we allow this baked oatmeal with blueberries to rest for 10 minutes or so. We serve this sweet treat at room temperature or slightly warm. Sometimes, sprinkle this dish with a bit more sugar at serving time–especially if those berries are on the tart side. This sweet breakfast dish pairs nicely with almond milk yogurt, a drizzle of non-dairy creamer, or a scoop of coconut ice cream.
Allow to rest for 10 minutes or so.
This blueberry oatmeal baked dish is great for meal prep as leftover baked oatmeal will keep in the refrigerator for up to a week. We just let the oatmeal cool to room temperature, seal in an air tight container, and set in the fridge. Now, let’s go enjoy our breakfast!
