Why You’ll Love Blueberry Baked Oatmeal Recipe

I enjoy this recipe because it’s easy to prepare and makes several servings at once. The baked texture is hearty and satisfying, while the blueberries add bursts of sweetness in every bite. I also appreciate how versatile it is since I can swap in different fruits, nuts, and toppings depending on what I have available. It’s a wholesome breakfast that tastes just as good fresh from the oven as it does reheated later.

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

⅔ cup roughly chopped pecans

2 cups old-fashioned oats

2 teaspoons ground cinnamon

1 teaspoon baking powder

¾ teaspoon fine-grain sea salt (or ½ teaspoon regular table salt)

¼ teaspoon ground nutmeg

1 ¾ cups milk of choice (almond milk, coconut milk, oat milk or cow’s milk all work)

⅓ cup maple syrup or honey

2 large eggs or flax eggs

3 tablespoons melted unsalted butter or coconut oil, divided

2 teaspoons vanilla extract

12 ounces or 1 pint fresh or frozen blueberries (or 2 ½ cups of your preferred berry/fruit, chopped into ½” pieces if necessary), divided

2 teaspoons raw sugar (optional)

Optional toppings for serving: plain/vanilla yogurt or whipped cream, additional maple syrup or honey for drizzling, and/or additional fresh fruit

Directions

I preheat the oven to 375°F and grease a 9-inch square baking dish.
Once the oven is heated, I spread the pecans on a rimmed baking sheet and toast them for 4 to 5 minutes until fragrant.
In a medium mixing bowl, I combine the oats, toasted pecans, cinnamon, baking powder, salt, and nutmeg.
In a separate bowl, I whisk together the milk, maple syrup or honey, eggs, half of the melted butter or coconut oil, and vanilla extract until smooth.
I reserve about ½ cup of the blueberries for the topping.
I scatter the remaining blueberries evenly across the bottom of the prepared baking dish.
I pour the dry oat mixture over the fruit.
I drizzle the wet mixture evenly over the oats.
I gently wiggle the baking dish to help the liquid distribute throughout the oats and lightly press down any dry oats on top.
I scatter the reserved blueberries over the surface and sprinkle with raw sugar if using.
I bake for 42 to 45 minutes, or 45 to 50 minutes if using frozen blueberries, until the top is golden brown.
I remove the oatmeal from the oven and allow it to cool for a few minutes.
I drizzle the remaining melted butter or coconut oil over the top before serving.
I serve it warm with my favorite toppings if desired.
