How to Make Blueberry Banana Oatmeal Casserole

Step 1

Preheat oven to 350°F. Grease a 9x13-inch or 2-quart casserole dish with nonstick cooking spray.
Step 2

In a large mixing bowl, combine the oats, chia seeds, flaxseed, ¼ cup almonds, cinnamon, nutmeg, and cardamom; set aside.
Step 3

In a medium mixing bowl, whisk together the eggs, milk, maple syrup, orange zest, and vanilla extract until well combined. Add to oat mixture and stir to combine. Gently fold in blueberries and bananas.
Step 4

Transfer mixture to prepared casserole dish. Sprinkle the top evenly with remaining almonds. Bake, uncovered, for 25 to 30 minutes, or until golden brown and a toothpick inserted into the center comes out clean.
Step 5

Serve warm and cut into 12 even single-serve bars. If desired, enjoy with additional blueberries or banana slices and a drizzle of maple syrup.
