Lemon Blueberry Baked Oatmeal (Printable)

Tender oats baked with juicy blueberries and bright lemon for a warm, satisfying breakfast.

# What You’ll 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 cooking spray or butter.
02 - In a large bowl, combine rolled oats, nuts (if using), baking powder, cinnamon, and salt. Mix well 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 blended and smooth.
04 - Pour the wet ingredients into the dry ingredients and stir until just combined. Do not overmix as this can affect texture.
05 - Gently fold in the blueberries, being careful not to crush them if using fresh berries.
06 - Transfer the mixture to the prepared baking dish and spread evenly. Sprinkle with coconut sugar or brown sugar if desired for a crisp topping.
07 - Bake for 35 minutes, or until the top is golden brown and the oatmeal is set (a knife inserted in the center should come out clean).
08 - Allow to cool for 5 minutes before serving. Serve warm, with extra milk or yogurt if desired.
