Casserole Ingredients

  • 8 slices slices of bread Cubed
  • 2 cups of milk
  • 4 large eggs
  • 1/2 cup of sugar
  • 1 teaspoon of alcohol-free vanilla extract
  • 1 teaspoon of cinnamon
  • 2 cups of fresh blueberries
  • Butter for greasing
  • Powdered sugar for serving (optional)

Instructions
 

Preparation

  • Preheat oven to 350°F (175°C). Grease a 9x13-inch baking dish with butter.
  • Cut bread into cubes. Place half the cubes in the prepared dish and sprinkle with half the blueberries.
  • Add remaining bread cubes and top with the rest of the blueberries.
  • In a bowl, whisk milk, eggs, sugar, vanilla, and cinnamon until smooth.
  • Pour the mixture evenly over the layered bread and berries. Press lightly so bread absorbs liquid.
  • Let sit 30 minutes at room temperature or refrigerate overnight for hands-off prep.
  • Bake for 35–40 minutes until golden and set.
  • Cool slightly, dust with powdered sugar if desired, and serve.

Notes

Cool completely, cover tightly, and refrigerate leftovers up to 3 days. Freeze individual portions in airtight containers for up to 1 month. Reheat in a 350°F oven for 10–15 minutes or microwave single portions for 60–90 seconds until warm.
