This Blueberry Banana Baked Oatmeal is so simple and quick to prepare and makes for a quick, healthy and hearty breakfast! It’s also perfect for brunch, or make it ahead for the week for easy meal prep.

The best part about this healthy baked oatmeal recipe is that it’s sweetened naturally with bananas and honey. You can also make it gluten-free by using gluten-free oats or dairy-free by using any milk you are tolerant with.

Be sure to keep the blueberries frozen until you add them so they don’t bleed purple color throughout the oatmeal. Also, adding the blueberries at the very end helps as well.
