How to Make Blueberry Baked Oatmeal Recipe
Step 1: Prepare Your Pan and Oven
Start by preheating your oven to 350°F and grease an 8×8-inch square baking pan. This step makes sure your oatmeal won’t stick to the pan and will bake evenly with a golden edge.
Step 2: Mix Dry Ingredients
Combine the oats, salt, baking powder, cinnamon, and brown sugar together in a small bowl. This dry mix is the base that will infuse the oatmeal with flavor and texture throughout.
Step 3: Whisk Wet Ingredients
In a separate bowl, whisk together the milk, eggs, and vanilla until smooth. This mixture is what will soak into the oats and create that creamy, custardy baked texture we all love.
Step 4: Combine Dry and Wet Mixtures
Pour the dry ingredients into the wet mix and stir them together until fully incorporated. Then, add the melted butter and fold it gently in.
Step 5: Add Blueberries
Gently mix in the blueberries, ensuring an even distribution without crushing them too much. This step guarantees delightful bursts of berry flavor in every bite.
Step 6: Bake to Perfection
Pour the oatmeal mixture into your prepared pan and bake for 45 to 55 minutes. You’ll know it’s done when the oatmeal is set and the top has turned a lovely golden color. Let it cool slightly before slicing into squares.
How to Serve Blueberry Baked Oatmeal Recipe
Garnishes
Enhance your blueberry baked oatmeal by topping it with a dollop of Greek yogurt or a drizzle of maple syrup for extra creaminess and sweetness. A sprinkle of toasted nuts or a few fresh blueberries on top creates a beautiful presentation that’s as inviting as it is tasty.

Make Ahead and Storage
Storing Leftovers
Store any leftover blueberry baked oatmeal in an airtight container in the refrigerator for up to four days. It keeps its flavor and texture beautifully, making for super easy breakfasts or snacks during the week.
Freezing
If you want to make this recipe in advance, you can freeze baked oatmeal squares individually wrapped in plastic wrap or foil, then placed in a freezer-safe bag. They’ll keep well for up to three months, perfect for quick mornings.
