Ingredients You’ll Need

One of the best things about this dish is how the ingredient list is purely composed of kitchen staples and a few star players. Each ingredient was chosen not just for flavor, but for the perfect balance of texture and pleasant pops of color that make Blueberry Baked Oatmeal irresistible.

Old-fashioned rolled oats: The foundation provides hearty texture and soaks up all the flavors beautifully.
Baking powder: Just a touch of leavening keeps your oatmeal soft and barely fluffy, never dense.
Ground cinnamon: Adds a gentle spice that warms the entire bake with comfort and nostalgia.
Salt: Balances the sweetness and brings out the flavors of oats and blueberries.
Milk (dairy or non-dairy): Binds the mixture and creates a custard-like interior—choose your favorite!
Maple syrup or honey: Lends natural sweetness and a hint of caramel nuance; either choice is delicious.
Large egg: Holds everything together and ensures you get perfect slices every time you serve.
Melted butter or coconut oil: For rich flavor and a tender crumb; coconut oil adds a subtle exotic twist if you’re feeling adventurous.
Vanilla extract: Rounds out the flavor, making everything taste a little more inviting.
Fresh or frozen blueberries: The star ingredient! Bursts of juicy tartness make every bite sing—no need to thaw if they’re frozen.
Chopped nuts (optional): Pecans or walnuts add a little crunch and a toasty undertone—completely up to you.

How to Make Blueberry Baked Oatmeal

Step 1: Preheat and Prepare Your Pan

Start by preheating your oven to 375°F (190°C). While it’s heating up, grease an 8×8-inch baking dish with butter or a bit of non-stick spray. This simple step ensures your Blueberry Baked Oatmeal comes out effortlessly once it’s time to serve, with perfectly intact edges every time.

Step 2: Mix the Dry Ingredients

In a large mixing bowl, combine the oats, baking powder, cinnamon, and salt. Give them a quick stir so the leavening and spices are evenly distributed—no one wants a mouthful of only cinnamon in the final dish! The oats form the backbone, so blending everything now gives structure to the bake later.

Step 3: Whisk the Wet Ingredients

Grab a separate bowl and whisk together the milk, maple syrup or honey, egg, melted butter (or coconut oil), and the vanilla extract. This is where the flavor magic happens. Combining them all together ensures an even distribution in the final Blueberry Baked Oatmeal, giving you a perfectly tender crumb in every bite.

Step 4: Combine Wet and Dry Mixtures

Pour your wet mixture into the bowl with the oats. Stir well so that every oat is coated and the mixture starts to thicken a little. You’ll notice the oats ready to start soaking up all that goodness, which leads to a delicious, custardy texture when baked.

Step 5: Fold in Blueberries and Nuts

Gently fold in your blueberries and nuts (if you’re using them). If your blueberries are frozen, toss them in straight from the freezer—this prevents them from turning the bake purple as they don’t have time to bleed. The nuts, meanwhile, add a lovely rustic crunch, but go with or without depending on your crowd.

Step 6: Bake to Golden Perfection

Pour the completed mixture into your prepared pan, spreading evenly with a spatula. If you like things a little sweeter, feel free to sprinkle a touch of brown sugar over the top. Slide it into the oven for 35 to 40 minutes, until the top is golden and the center has set. Let it cool for a few minutes—Blueberry Baked Oatmeal slices best when it’s warm, not hot.

How to Serve Blueberry Baked Oatmeal

Garnishes

Top your squares with a drizzle of maple syrup, a dollop of Greek yogurt, or maybe a scattering of extra fresh blueberries. For something extra decadent, a small pat of butter melting over the warmth is positively dreamy. These little touches make every serving look and taste even more inviting.

Side Dishes

This oatmeal bake loves good company. Try pairing it with crisp bacon, turkey sausage, or a platter of seasonal fruit for a full brunch spread. Even a simple smoothie or a hot cup of coffee makes Blueberry Baked Oatmeal feel like a special occasion.

Creative Ways to Present

Cut the bake into small squares for grab-and-go breakfast bites, or use a round biscuit cutter for mini oatmeal “cakes.” Hosting a brunch? Serve each portion in a small ramekin with a blueberry compote and a sprig of mint for a touch of restaurant flair.

Make Ahead and Storage

Storing Leftovers

Blueberry Baked Oatmeal stores beautifully in the fridge. Once completely cooled, cover the dish with foil or transfer portions to airtight containers. You can expect it to stay fresh for up to five days—just the thing for busy mornings or snack attacks.

Freezing

For longer storage, freeze individual squares on a baking sheet, then place them in a freezer-safe bag or container. This way, you can thaw one or two at a time. Blueberry Baked Oatmeal will keep its flavor and texture well for up to three months in the freezer.

Reheating

To reheat, simply pop a square in the microwave for about a minute, or warm several in a covered dish in the oven at 325°F (163°C) until heated through. A splash of milk over the top before reheating keeps everything moist and delicious.

FAQs

Can I use steel-cut oats instead of rolled oats?

Steel-cut oats require more liquid and a longer bake time, so they aren’t a direct swap in this recipe. Stick with old-fashioned oats for the ideal creamy-yet-textured results in your Blueberry Baked Oatmeal.

Are frozen blueberries as good as fresh?

Absolutely! Frozen blueberries are picked at peak ripeness and lend the same flavor as fresh. Just add them straight from the freezer to keep your Blueberry Baked Oatmeal from getting purple streaks.

Can I make Blueberry Baked Oatmeal dairy-free?

Yes! Non-dairy milk like almond, oat, or soy works perfectly, and substituting coconut oil for the butter makes the whole recipe dairy-free without sacrificing taste or texture.

Is it possible to double this recipe?

Doubling is easy—just bake the mixture in a 9×13-inch pan and keep an eye on the oven as you may need a few extra minutes for the center to set. It’s a wonderful way to feed a crowd with minimal effort.

Can I add other fruits or mix-ins?

Definitely! Swap or add raspberries, diced apples, strawberries, or even chocolate chips. Blueberry Baked Oatmeal is endlessly customizable to what you have on hand or your family’s favorites.

Final Thoughts

If you’re looking for a breakfast that’s comforting, nourishing, and packed with berry goodness, you can’t do better than Blueberry Baked Oatmeal. It’s a recipe that’s as delightful for guests as it is for quiet mornings at home. Try it just once, and chances are it’ll earn a regular spot in your kitchen, too.
