Blueberry Baked Oatmeal

This blueberry baked oatmeal is studded with blueberries and naturally sweetened with bananas and pure maple syrup. Can be made with fresh or frozen blueberries! Gluten-free and vegan-friendly.

We kicked off Oatmeal Week with baked oatmeal cups, but today we’re doing a full-on baked oatmeal recipe that bakes in a square baking dish.

This variation of baked oatmeal is still uber healthy and perfect for meal prep, but it’s also great for entertaining. Whenever we’re having friends or family over for breakfast or brunch, baked oatmeal is on the menu. Sometimes I’ll also make a frittata so we have two options (one sweet and one savory) for everyone to enjoy.

I’ve personally been hooked on baked oatmeal for a few years, ever since I shared this baked oatmeal recipe that everyone LOVES. I recently decided that I needed to experiment with different baked oatmeal flavor combinations and blueberries immediately came to mind!

Blueberry Health Benefits

I love blueberries because they’re available year-round (fresh or frozen) . . . and they taste delicious year round too! They’re also known for being a superfood because they contain some of the highest antioxidant levels compared to most common fruits and veggies. They have also been shown to help improve chronic diseases like heart disease, blood pressure and diabetes.

Here’s What You Need:

• rolled old-fashioned oats
• pure maple syrup
• baking powder
• ground cinnamon
• sea salt
• unsweetened vanilla almond milk
• egg or flaxseed egg
• coconut oil
• pure vanilla extract
• bananas
• fresh or frozen blueberries

This baked oatmeal is sweetened with a little bit of maple syrup and bananas, making it the perfect example of a baked breakfast that doesn’t need a ton of sugar to be delicious.

Of course, if you do feel like you want your baked oatmeal to be a little sweeter, you can always add a drizzle of maple syrup on it right before you dig in. 🙂

Prepping & Storing Baked Oatmeal

One of my favorite things about baked oatmeal is that you can prep it ahead of time. There are a couple options that work really well. Here’s what I recommend:

Option 1: Bake and Then Reheat Before Serving

1. Prepare baked oatmeal as the recipe suggests. Once baked, let the oatmeal cool, cover the baking dish and place in the fridge. You can do this 1-2 days in advance.
2. When ready to serve, take oatmeal dish from fridge, cover with foil and reheat in a 350°F oven for about 20 minutes. For individual portions, set toaster oven to 350°F and bake for 5-10 minutes or reheat in the microwave for 1 minute.

Option 2: Prep as Much as You Can Without Baking

1. Mix together your dry ingredients in a bowl, cover and let sit out on the counter until morning.
2. Mix together all the wet ingredients in another bowl, cover and store in the fridge until morning.
3. In the morning, simply mix the wet and dry ingredients together, pour oatmeal mixture into your prepared baking dish and bake as recipe suggests.

This baked oatmeal is good on it’s own, but to me, oatmeal isn’t complete without a drizzle of nut butter so I always serve my baked oatmeal with a drizzle of peanut butter or almond butter on top. So yummy!
