Blueberry baked oatmeal is one of those cozy recipes that brings me back to quiet weekend mornings in my first apartment. I didn’t have much back then—not even a proper mixing bowl—but I always had oats, milk, and frozen berries in the pantry. One Sunday, with music humming softly in the background and sunlight coming through the window, I decided to try something different and bake my usual oats. I didn’t expect much, but the result? Absolutely perfect and totally comforting.

That experiment quickly became a regular favorite and I’ve refined it since. Now I make it with plump blueberries that burst in the oven and warm spices that fill the kitchen with the most inviting aroma. Whether it’s a lazy Sunday or a busy weekday, this baked oatmeal recipe is like a warm hug you can eat.

Ingredients

Here’s what I use for this recipe. You can always make substitutions if you prefer!
Rolled oats – They give the dish structure and a chewy texture
Blueberries – These add sweetness and a juicy, tart contrast to the oats
Baking powder – This helps the oatmeal bake evenly and gives it a slight lift
Cinnamon – For cozy, warm flavor in every bite
Salt – To balance and enhance all the flavors
Milk – Adds moisture and binds everything together
Egg – Helps hold the oats together and creates a custardy finish
Maple syrup – Adds natural sweetness with rich caramel notes
Vanilla extract – Rounds out the flavors with a soft, aromatic touch
Coconut oil (or butter) – Adds richness and helps with browning

Tools You’ll Need

Mixing bowl – I use this to combine the wet and dry ingredients easily
Whisk – Perfect for blending the egg, milk, and other wet ingredients smoothly
Baking dish – I bake everything in this, it ensures even cooking and golden edges
Measuring cups and spoons – To keep the proportions just right
Oven – Essential for that baked golden top and warm center

Instructions

Step 1: Preheat and prep

I start by preheating the oven to 375°F and lightly greasing a small baking dish with coconut oil or butter.

Step 2: Mix the dry ingredients

In a mixing bowl, I stir together the rolled oats, baking powder, cinnamon, and salt. I make sure everything is well combined.

Step 3: Whisk the wet ingredients

In another bowl, I whisk the egg with the milk, maple syrup, vanilla extract, and melted coconut oil until smooth.

Step 4: Combine everything

I pour the wet mixture into the bowl of dry ingredients and stir gently until everything is moistened. Then I fold in most of the blueberries, saving a few for the top.

Step 5: Assemble and bake

I pour the mixture into the prepared baking dish, spreading it out evenly. Then I scatter the reserved blueberries on top and bake it for 35–40 minutes, or until the top is golden and the center is set.

Step 6: Cool slightly and serve

I let it cool for about 5 minutes before slicing and serving. That way, it holds its shape better and doesn’t burn your tongue!

Tips

If I want to add extra texture, I like tossing in chopped nuts like pecans or almonds. Sometimes I switch out the blueberries for chopped apples or raspberries depending on the season. And for a dairy-free option, I’ve used almond milk or oat milk with great results!

Ways to Serve

I love serving this warm with a spoonful of Greek yogurt and a drizzle of maple syrup on top. It also tastes great cold the next day, sliced into bars for a quick breakfast. You can even top it with a scoop of nut butter or a splash of milk to bring it back to life!
