Description

A comforting and wholesome Blueberry Baked Oatmeal recipe featuring cubed bread soaked in a cinnamon-vanilla custard with fresh or frozen blueberries, baked to golden perfection. This easy-to-make breakfast casserole offers a warm, fruity start to your day and can be customized with nuts and a dusting of powdered sugar.


Ingredients

Scale

Bread and Fruit

  • 6 cups cubed bread (brioche, challah, or French bread)
  • 2 cups fresh or frozen blueberries

Custard Mixture

  • 4 large eggs
  • 1 ½ cups milk (or dairy-free alternative)
  • ½ cup heavy cream (or coconut cream)
  • ½ cup maple syrup or honey
  • 1 tsp vanilla extract
  • 1 tsp cinnamon
  • ¼ tsp salt

Toppings (Optional)

  • ½ cup chopped nuts
  • Powdered sugar, for serving


Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C), ensuring it reaches the right temperature for baking the oatmeal evenly.
  2. Prepare Baking Dish: Lightly grease a 9×13-inch baking dish to prevent sticking and to help with even browning.
  3. Lay Bread Cubes: Spread the cubed bread evenly across the bottom of the prepared baking dish to form the base layer.
  4. Add Blueberries: Evenly sprinkle fresh or frozen blueberries over the bread cubes to distribute fruit flavor throughout.
  5. Mix Custard: In a large bowl, whisk together eggs, milk, heavy cream, maple syrup, vanilla extract, cinnamon, and salt until smooth and combined.
  6. Combine: Pour the custard mixture evenly over the bread and blueberries, pressing down gently with a spatula to ensure all pieces absorb the custard.
  7. Rest Mixture: Let the dish sit for 10 minutes to allow the bread to soak up the custard fully. For enhanced flavor, cover and refrigerate overnight.
  8. Add Nuts (Optional): Sprinkle chopped nuts on top if desired for added texture and flavor contrast.
  9. Bake: Bake in the preheated oven for 35-40 minutes until the top turns golden brown and the custard is set in the center.
  10. Cool and Serve: Allow the baked oatmeal to cool slightly before dusting with powdered sugar, then serve warm for the best taste experience.

Notes

  • You can substitute the heavy cream with coconut cream for a dairy-free option.
  • For added flavor, soak the mixture overnight in the refrigerator before baking.
  • Chopped nuts are optional but add great crunch and nutrition.
  • Use maple syrup or honey based on your preference for sweetness.
  • Fresh or frozen blueberries both work well; no need to thaw frozen berries before using.
  • Powdered sugar topping is optional and adds a lovely touch of sweetness and presentation.
