Blueberry Banana Baked Oatmeal

I love having toddler breakfasts ready to go for my entire family, and this easy baked oatmeal is a favorite option—the flavor from the berries and banana is just so delicious. It stirs together really easily; has a load of nutritious ingredients including oats, chopped nuts or seeds, and fruit; and is perfect for any age. It’s a great make-ahead breakfast—and special enough to serve for a family brunch—that we love to top with butter and maple syrup. It’s also delicious with a big dollop of yogurt. Older babies can eat it as a baby finger food, too. This is one of my favorite baked oatmeal recipes to enjoy all year round.

Milk: I typically bake with whole-dairy milk, but you can use any type you prefer, including nondairy milk. Banana: I like to add ripe banana to the base of my baked oatmeal for extra sweetness (and then I don’t add any other sweetener). Eggs: This oatmeal bakes up slightly firm with the help of both the bananas and large eggs in the mix. Vanilla: I add vanilla extract to this recipe to round out the flavors. You can use pure vanilla extract or imitation. Rolled oats (old-fashioned oatmeal): This forms the base of the baked oatmeal, so look for it in your cereal aisle. Walnuts (or pecans): For a little extra texture and nutrition (including fiber and beneficial fats), I like to add finely chopped walnuts or pecans. To make this nut-free, you could use a seed your family likes or simply replace the volume with additional oats. Cinnamon: Cinnamon is a delicious addition in the mix with the vanilla and fruit flavors. Baking powder: A little baking powder helps the mixture rise just enough to have a better texture than if we didn’t use it. Blueberries: You can use fresh or frozen blueberries here. (Learn how to freeze blueberries to take advantage of sales.) I particularly love using frozen wild blueberries since they have such intense flavor. Butter, maple syrup, yogurt, optional for serving

How to Store

Once cooled, cover blueberry banana baked oatmeal with foil or transfer squares to an airtight container and store in the fridge for up to a week. Warm in the microwave or toaster oven. You can also slice and freeze in a freezer bag for up to 6 months. Do your best to remove as much air as you can from the bag to minimize freezer burn. Learn more in my guide to freezing food.

Best Tips for Success

Serve blueberry banana baked oatmeal cold or warm with butter, maple syrup, whipped cream, or regular or Greek yogurt. Skip the nuts and replace with additional oats or shredded unsweetened coconut, as you like. Buy chopped nuts from the store and/or finely chop them to ensure they are very tiny pieces, which are easier to chew, more pleasant in the mix, and not considered to be a choking hazard. To make this egg-free, omit the eggs and add ½ cup more banana (for ¾ cup total). Use dairy-free milk as needed. Use gluten-free rolled oats as needed. Use another berry on top as desired. Serve with Flavored Milk, a Toddler Smoothie, or a Kids Protein Shake. If you have extra blueberries, try Blueberry Yogurt, Blueberry Popsicles, and Oatmeal Bars with Blueberries.
