Ingredients You’ll Need
This Blueberry Baked Oatmeal couldn’t be simpler; each ingredient plays a big role in flavor or texture. A handful of pantry and fridge staples come together to create something that tastes like a cozy embrace, with blueberries adding vibrant bursts of color and sweetness to every bite.
- Old-fashioned rolled oats: These form the base and give the oatmeal its chewy, hearty texture—steel cut oats won’t work the same magic here!
- Chopped walnuts or pecans (optional): Bring lovely crunch and a boost of richness—toast them first for deeper flavor.
- Baking powder: The secret to a lighter, almost cake-like bake, allowing the oatmeal to rise beautifully.
- Ground cinnamon: Adds comforting warmth that pairs perfectly with blueberries.
- Salt: Just a pinch to balance the sweetness and make all the flavors pop.
- Milk (dairy or non-dairy): Keeps the oats creamy and can be customized to your preference; almond or oat milk both work wonderfully.
- Maple syrup or honey: Naturally sweetens without overpowering—maple syrup is particularly dreamy with blueberries.
- Large egg: Helps bind everything together for perfect slices every time.
- Melted coconut oil or butter: Adds richness and softness; coconut oil gives a subtle tropical hint, butter offers classic coziness.
- Vanilla extract: Elevates the whole dish with its sweet, floral aroma.
- Fresh or frozen blueberries: The star ingredient! Frozen berries can go straight in—no need to thaw.
- Extra blueberries and nuts for topping (optional): A finishing flourish for more bite, color, and a wow-worthy look.
How to Make Blueberry Baked Oatmeal
Step 1: Prep Your Baking Dish and Oven
Begin by preheating your oven to 375°F. This ensures a nice even bake and a golden top. Lightly grease an 8×8-inch baking dish with butter or cooking spray so nothing sticks and cleanup is effortless.
Step 2: Mix the Dry Ingredients
Grab a large mixing bowl and combine the old-fashioned oats, chopped nuts if you’re using them, baking powder, ground cinnamon, and salt. Whisking these together first guarantees those spices and leavening agents are evenly distributed throughout each bite.
Step 3: Whisk the Wet Ingredients
In a separate bowl, whisk together your milk of choice, maple syrup (or honey), egg, melted coconut oil or butter, and vanilla extract. Be sure your oil or butter isn’t piping hot to avoid scrambling the egg—nobody wants that!
Step 4: Combine Wet and Dry Mixtures
Pour the wet ingredients into the dry mixture, and stir until everything is smooth and nicely blended. This is where the magic starts, as oats begin soaking up all those sweet and aromatic flavors.
Step 5: Gently Fold in Blueberries
Now comes the best part—add in your fresh or frozen blueberries. Give everything a gentle fold with a spatula to avoid smooshing the berries, distributing them evenly through the oatmeal.
Step 6: Bake to Golden Perfection
Pour the oatmeal mixture into your prepared baking dish, spreading it out so it’s even. Sprinkle extra blueberries and nuts on top if you like—they’ll toast up beautifully. Bake for 35 to 40 minutes, until the oatmeal is set in the center and the top is gloriously golden. Let it cool for 5 to 10 minutes before digging in; this helps it slice neatly and allows the flavors to settle.
How to Serve Blueberry Baked Oatmeal

Garnishes
For the prettiest and most flavorful results, scatter extra fresh blueberries and a handful of chopped nuts across the top right before serving. A drizzle of maple syrup or a dollop of creamy yogurt also takes this Blueberry Baked Oatmeal to the next level of deliciousness.
Side Dishes
This oatmeal is already crave-worthy on its own, but if you want to round out your breakfast, try serving with crispy turkey bacon, fluffy scrambled eggs, or a vibrant fruit salad. The combination makes for a filling, energizing start to any day.
Creative Ways to Present
For brunch get-togethers, slice Blueberry Baked Oatmeal into neat squares and stack them on a platter, or bake it in individual ramekins for personal servings. You can even layer squares with Greek yogurt and a handful of granola for a stunning “breakfast parfait” presentation that has swoon-worthy layered appeal.
Make Ahead and Storage
Storing Leftovers
Leftover Blueberry Baked Oatmeal makes the ultimate grab-and-go breakfast. Allow the oatmeal to cool completely before covering and popping it into the fridge. It stays fresh and tasty for up to four days—just slice and serve as needed.
Freezing
If you want to plan far ahead, this dish freezes remarkably well. Cut cooled oatmeal into individual servings, wrap them tightly, and stash them in an airtight container. They’ll keep for a month; just thaw overnight in the fridge for an easy breakfast solution.
Reheating
To reheat, simply microwave individual slices for 30 to 60 seconds, or warm a batch in the oven at 350°F for about 10 minutes. Add a splash of milk before reheating if you like it extra creamy. The baked oatmeal returns to soft, freshly-baked glory in no time.
FAQs
Can I use steel cut oats instead of rolled oats?
It’s best to stick with old-fashioned rolled oats since they yield the creamiest, most tender Blueberry Baked Oatmeal. Steel cut oats will stay too tough and won’t cook through properly in this recipe.
Do I need to thaw frozen blueberries before baking?
There’s no need to thaw your blueberries—simply toss them right in, straight from the freezer! They’ll bake up beautifully, releasing juices and adding luscious bursts of flavor throughout the oatmeal.
What can I use instead of nuts for a nut-free version?
Not a fan of nuts or need a nut-free option? Try stirring in sunflower seeds or pumpkin seeds for crunch, or simply leave them out—the Blueberry Baked Oatmeal will still come out soft, moist, and delicious.
Is this recipe gluten-free?
If you use certified gluten-free rolled oats, then yes! Every other ingredient in this Blueberry Baked Oatmeal is naturally gluten-free, so it’s a great option for those with sensitivities.
How do I make it vegan?
Simply use your favorite non-dairy milk (like almond or oat), swap the egg for a flax egg (1 tablespoon flaxseed meal + 2.5 tablespoons water), and choose maple syrup for sweetness. Coconut oil is perfect for keeping it plant-based!
Final Thoughts
If you’re craving a breakfast that feels like an indulgence but keeps you fueled and energized, give Blueberry Baked Oatmeal a try. It promises cozy comfort food vibes, an easy make-ahead routine, and pure blueberry bliss in every bite. I can’t wait for you to discover just how delightful mornings can be!
