Lemon Blueberry Baked Oatmeal (Printable Version)

Tender baked oats with fresh blueberries and bright lemon flavors make this wholesome breakfast perfect for meal prep and busy mornings.

# Ingredient List:

→ Dry Ingredients

01 - 2 cups old-fashioned rolled oats
02 - 1/2 cup chopped walnuts or almonds
03 - 1 teaspoon baking powder
04 - 1/2 teaspoon ground cinnamon
05 - 1/2 teaspoon salt

→ Wet Ingredients

06 - 2 cups milk
07 - 1/4 cup maple syrup or honey
08 - 2 large eggs
09 - 1/4 cup unsalted butter, melted
10 - 1 tablespoon lemon zest
11 - 1 teaspoon pure vanilla extract
12 - 2 tablespoons fresh lemon juice

→ Add-ins

13 - 1 1/2 cups fresh or frozen blueberries

→ Topping

14 - 2 tablespoons coconut sugar or brown sugar

# How to Make:

01 - Preheat the oven to 350°F and lightly grease a 9x9-inch baking dish with cooking spray or butter.
02 - In a large bowl, combine rolled oats, nuts, baking powder, cinnamon, and salt. Mix thoroughly to distribute evenly.
03 - In a separate bowl, whisk together milk, maple syrup, eggs, melted butter, lemon zest, vanilla extract, and lemon juice until fully incorporated.
04 - Pour the wet ingredients into the dry ingredients and stir until just combined. Avoid overmixing to prevent tough texture.
05 - Gently fold in the blueberries, taking care not to crush them. If using frozen blueberries, add them directly from the freezer.
06 - Transfer the mixture to the prepared baking dish and spread evenly with a spatula. Sprinkle with coconut sugar or brown sugar if desired.
07 - Bake for 35 minutes, or until the top is golden brown and the oatmeal is set. A toothpick inserted in the center should come out moist but not liquidy.
08 - Allow to cool for 5 minutes before serving. Serve warm, with extra milk or yogurt if desired.

# Expert Tips:

01 -
  • It tastes like dessert but powers you through a whole morning without that midday crash
  • The blueberries burst in your mouth creating little pockets of jammy sweetness
02 -
  • Do not overmix the batter or your oatmeal will turn tough instead of tender
  • Using frozen blueberries straight from the freezer prevents them from bleeding into the batter too much
03 -
  • Use room temperature eggs and milk to prevent the melted butter from solidifying when you mix it
  • Zest your lemon before juicing it, much easier to handle the whole fruit at once
