Lemon Blueberry Baked Oatmeal (Printer-Friendly)

Wholesome breakfast baked with oats, fresh blueberries, and bright lemon flavors.

# What You'll Need:

→ 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 (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

# How-To Steps:

01 - Preheat the oven to 350°F. Lightly grease a 9x9-inch baking dish with butter or cooking spray.
02 - In a large mixing bowl, combine rolled oats, chopped nuts (if using), baking powder, ground cinnamon, and salt. Whisk briefly to distribute evenly.
03 - In a separate medium bowl, whisk together milk, maple syrup, eggs, melted butter, lemon zest, vanilla extract, and fresh 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 light folding motion to distribute them evenly without crushing the fruit.
06 - Transfer the mixture to the prepared baking dish and spread 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 the oatmeal is set. A toothpick inserted in the center should come out clean.
08 - Allow the baked oatmeal to cool for 5 minutes before serving. Serve warm, optionally with additional milk or yogurt on the side.

# Expert Hints:

01 -
  • It tastes like lemon blueberry muffins but feels lighter and more wholesome
  • The texture is somewhere between cake and custard, pure breakfast comfort
02 -
  • Do not overmix when combining wet and dry ingredients or the texture becomes dense instead of tender
  • Letting it rest for those 5 minutes after baking makes all the difference for clean servings
03 -
  • Use a microplane for the lemon zest to get just the outer yellow layer, none of the bitter white pith
  • If using frozen blueberries, keep them frozen until the moment you fold them in to prevent bleeding
