This blueberry baked oatmeal is a healthy breakfast that is perfect for meal prepping for the week ahead!
Last year, we ran an overnight oats series and got an amazing response! So, we wanted to bring you more ways to mix up your morning oats. This time, we’re bringing you blueberry baked oatmeal. This oatmeal bake is great for colder months when you’d prefer a warm breakfast. It tastes like a cross between a granola bar and the traditional oatmeal you’d make on your stovetop. Inside, the consistency is creamy and chewy, while the top and edges are crisp and buttery. It is bursting with bright blueberry flavor, cinnamon, and vanilla. This baked oatmeal can be quickly whipped up in one bowl for the week ahead, and once it is done baking you can cut it into squares and pack it into individual containers for a grab-and-go breakfast.
Blueberry Baked Oatmeal Ingredients
Here’s what you’ll need to make this baked oatmeal:
- Oats – We recommend using old-fashioned rolled oats for this recipe as they cook up the best. Steel-cut oats won’t cook fast enough. While oats are naturally gluten-free, they are often grown alongside wheat and easily cross-contaminated. So, if you have Celiac Disease or are super gluten-sensitive, look for certified gluten-free oats like these from Bob’s Red Mill.
- Eggs – The eggs in this recipe help bind the oats together to make it a casserole. We haven’t tried any egg replacers, but if you do, let us know in the comments!
- Milk – You can use whatever milk you prefer here! Whole milk, almond milk, cashew milk, and oat milk will all work.
- Maple Syrup – We chose to use pure maple syrup as our sweetener here because it goes perfectly with oats!
- Cinnamon & Vanilla – Cinnamon and vanilla are two other spices that pair perfectly with oats and lend a nostalgic taste to this dish.
- Baking Soda – The baking soda helps the oat bake rise just a little so it’s not too dense.
- Chopped Pecans – The chopped pecans add a bit of crunch and a delicious toasted flavor. However, you can easily leave them out or substitute them for whatever nut you prefer!
- Blueberries – The blueberries add a bright burst of berry flavor to each bite.
- Butter – The butter poured over the top gives it a delicious crisp. If you can’t have dairy, feel free to use your favorite vegan butter substitute or coconut oil.
How to Make Baked Oatmeal
Making baked oatmeal is so simple! All you need is one bowl for mixing it up, and a dish to bake it in. First, you’ll whisk up all of the wet ingredients (milk, eggs, syrup, and vanilla) until well combined, then you’ll stir in the baking soda, cinnamon, oats, and pecans, and finally, the blueberries. Once everything is mixed together, you’ll pour it into a well-greased baking dish, and bake at 375°F for 25-30 minutes, until browned.
Can this be made egg-free?
It can! In order to do this, you’ll need ground chia seeds and oat flour. Simply combine 2 tablespoons of ground chia seeds + 6 tablespoons of water and let the mixture rest for 5-10 minutes. Then, combine the ‘chia egg’ with the rest of the wet ingredients (milk, syrup, and vanilla), stir in the dry ingredients (with the addition of 1/2 cup of oat flour), and bake at 375°F for 25-30 minutes, until browned!
How long will this keep for?
This blueberry baked oatmeal will keep for about 5 days in the refrigerator. If you’d like, you can cut it into squares once cool then portion it into individual containers for a quick grab-and-go breakfast. To reheat, simply microwave an individual square on high for 60 to 90 seconds, or place in an oven-safe container in a preheated 350°F oven and heat for 7 to 9 minutes, until warmed through.
You can also freeze it for up to 5 months! To reheat, just microwave from 2 to 2 1/2 minutes, or bake for 15-20 minutes in a preheated 350 F oven.
Toppings for Baked Oatmeal
While baked oatmeal is great on its own, you can make it even tastier by adding toppings! Here are a few of our favorites:
- Yogurt – We love using full-fat, plain Greek yogurt here as a way to add some extra protein and keep you full for longer. If you’re dairy-free, just sub your favorite yogurt instead!
- Fresh Fruit – While there are already blueberries inside, a little bit of fresh fruit on top is great, too. Our favorites are berries, pomegranate seeds, and bananas.
- Honey – A drizzle of honey, especially if you’re using plain yogurt, makes for a deliciously sweet finish.
- Whipped Coconut Cream – This is a great yogurt alternative, especially if it isn’t easy to find dairy-free yogurt in your area! You can find our whipped coconut cream here.
- Nut Butter – A drizzle of nut butter is not only a tasty topping, it also adds satiating fats and protein to the dish.
