Lemon Blueberry Baked Oatmeal (Print)

A wholesome breakfast bake with juicy blueberries, zesty lemon, and hearty oats for a satisfying morning meal.

# 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)

# How To Make It:

01 - Preheat the oven to 350°F. Lightly grease a 9x9-inch baking dish with butter or cooking spray.
02 - In a large bowl, add rolled oats, nuts (if using), baking powder, cinnamon, and salt. Mix thoroughly to distribute the baking powder and spices evenly.
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 mixture into the dry ingredients. Stir gently with a spatula or wooden spoon until just combined, being careful not to overmix.
05 - Gently fold the blueberries into the batter, taking care not to crush them. If using frozen blueberries, add them directly from the freezer.
06 - Pour the mixture into the prepared baking dish and spread it evenly with a spatula. Sprinkle the top with coconut sugar or brown sugar if using.
07 - Bake for 35 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean. The oatmeal should be set but still slightly moist.
08 - Let the baked oatmeal cool for 5 minutes before serving. Serve warm, optionally topped with additional milk, yogurt, or fresh berries.
