Lemon Blueberry Baked Oatmeal (Printable Version)

A wholesome breakfast baked with oats, blueberries, and lemon zest.

# What You Need:

→ Dry Ingredients

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

→ Wet Ingredients

06 - 2 cups milk (dairy or plant-based)
07 - 1/4 cup maple syrup or honey
08 - 2 large eggs
09 - 1/4 cup unsalted butter, melted (or coconut oil)
10 - 1 tablespoon lemon zest (from about 1 large lemon)
11 - 1 teaspoon pure vanilla extract
12 - 2 tablespoons fresh lemon juice

→ Add-ins

13 - 1 1/2 cups fresh or frozen blueberries (do not thaw if frozen)

→ Topping

14 - 2 tablespoons coconut sugar or brown sugar (optional)

# Directions:

01 - Preheat the oven to 350°F (175°C). Lightly grease a 9x9-inch (23x23 cm) baking dish with butter or cooking spray.
02 - In a large bowl, add rolled oats, nuts (if using), baking powder, cinnamon, and salt. Whisk together until evenly distributed.
03 - In a separate medium bowl, whisk together milk, maple syrup, eggs, melted butter, lemon zest, vanilla extract, and lemon juice until completely smooth and well blended.
04 - Pour the wet ingredients into the dry ingredients. Stir with a spatula or wooden spoon until just combined, being careful not to overmix.
05 - Gently fold in the blueberries using a folding motion to distribute them evenly without crushing.
06 - Pour the mixture into the prepared baking dish and spread evenly with a spatula. Sprinkle coconut sugar or brown sugar over the top 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 mostly clean).
08 - Allow the baked oatmeal to cool for 5 minutes before serving. Serve warm, optionally topped with extra milk or yogurt.

# Expert Tips:

01 -
  • The lemon brightens up the hearty oats in a way that feels like sunshine on a plate
  • You can prep everything the night before and just bake it in the morning
  • Leftovers reheat beautifully for quick breakfasts all week long
02 -
  • Dont overmix when combining wet and dry ingredients or the texture will become gummy
  • The oatmeal will continue to set as it cools, so dont worry if it seems slightly jiggly right out of the oven
  • Frozen blueberries can make the baking time vary by a few minutes, so trust your eyes more than the timer
03 -
  • Room temperature ingredients blend more smoothly and prevent the melted butter from solidifying
  • If using frozen blueberries, toss them in a tablespoon of flour before adding to prevent them from sinking
  • Let the lemon zest sit in the sugar for a few minutes before mixing to release more oils
