Blueberry Oatmeal Bake
We all want to provide our family with a nutritious meal to start the day, and this blueberry baked oatmeal is an incredibly delicious breakfast that will keep everyone full and energized for hours.
Oats are an excellent source of fiber and complex carbs, which help keep us feeling full and provide long-lasting energy.
There are so many things to make with oatmeal, like my overnight oats recipes and while single-serve oatmeal jars are practical, some mornings I feel like eating warm oats right out of the oven with a little milk over the top. Nothing beats that!
Blueberry Baked Oatmeal Ingredients
Ready to whip up your baked oatmeal? Run to the pantry and pull out these healthy ingredients:
- old-fashioned oats: for baked oatmeal recipes, old-fashioned oats work best. I don’t recommend steel-cut or instant.
- baking powder: helps the batter rise.
- salt: enhances the other flavors.
- honey: just enough to give the baked oatmeal a touch of sweetness.
- milk: use any milk or non-dairy alternative.
- egg: binds the batter ingredients and helps it rise.
- butter: flavor purposes and to moisten the baked oatmeal.
- vanilla: makes it more like cake!
- blueberries: infuses the oats with tangy-sweet berry flavor!
This recipe is successful with frozen or fresh blueberries, so you can make this any time of the year! Frozen and wild blueberries may give your oatmeal a purplish color, but the baked oatmeal will taste amazing either way.

Baked oatmeal is easy to turn into an allergy-friendly breakfast. Oats are naturally gluten-free, and ingredient swaps below show you how to make this recipe egg and dairy-free.
- egg: use a flax egg instead. Mix 3 tablespoons warm water with 1 tablespoon ground flax. Wait 10 minutes until a gel-like mixture forms.

Can You Freeze Baked Oatmeal
Baked oatmeal holds up well in the freezer and reheats with the same delicious flavor and texture you get when it’s fresh from the oven. The color might be a little more purple, but this usually isn’t an issue since the flavor is all there.
To freeze baked oatmeal, place single portions into freezer-safe containers and seal. Freeze for up to 2 months.
The night before you plan to serve it for breakfast, transfer the baked oatmeal to the fridge and let it thaw out. In the morning, reheat it in the microwave, and enjoy.
Best Baked Oatmeal Success Tips
Before you get to the kitchen, here are a few simple tips to make perfect baked oatmeal every time!
Use enough liquid
The oats need just enough liquid to soak up and turn into a cakey, bread pudding texture.
Don’t swap oats
This recipe uses old-fashioned oats. The large flakes soak up all the liquid and won’t dry out. Exchanging them for instant or steel-cut outs would require changing the other ingredient ratios.
Want to bake this the night before? Good thinking. Prepare as directed and allow the baking dish to reach room temperature before covering with plastic wrap and refrigerating. Reheat the entire baking dish in the oven at 375F for 10 minutes or place a serving into a microwave-safe bowl and reheat for 1 to 2 minutes.
