Lemon Blueberry Baked Oatmeal (Print View)

Bright lemon and blueberry baked oatmeal with hearty oats and warm spices

# 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. 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 spices evenly.
03 - In a separate medium 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. Stir with a spatula until just combined, being careful not to overmix.
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 using.
07 - Bake for 35 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
08 - Allow to cool for 5 minutes before serving. Serve warm, optionally topped with additional milk or yogurt.

# Expert Advice:

01 -
  • The lemon and blueberry combination tastes like sunshine on a cloudy morning, bright enough to wake you up without coffee
  • You can assemble everything the night before and just bake it when you wake up, making busy mornings feel luxurious
02 -
  • The oatmeal continues to firm up as it cools, so do not panic if it seems slightly jiggly right when you pull it from the oven
  • Frozen blueberries actually work better than fresh here since they release more juice during baking, creating those beautiful purple swirls throughout
03 -
  • Use room temperature eggs and milk to prevent the melted butter from solidifying when you mix everything together
  • Let the lemon zest sit in the melted butter for a few minutes before mixing, this infuses the fat with even more lemon flavor
