Ingredients
  

For the casserole
  • 1 loaf bread (French or challah), preferably day-old or slightly stale, cut into 1-inch cubes Stale bread absorbs custard better.
  • 6 large eggs
  • 2 cups milk (whole, almond, or oat) Use non-dairy milk for allergy-friendly option.
  • 1 cup fresh blueberries Frozen works — do not thaw fully to avoid excess bleeding.
  • 1/4 cup granulated sugar (or swap with 1/4 cup maple syrup)
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 1 tablespoon butter for greasing the baking dish

Method
 

Preparation
  1. Preheat the oven to 350°F (175°C). Generously butter a 9x13-inch baking dish.
  2. Cut the loaf into 1-inch cubes and spread half of them evenly in the prepared dish.
  3. In a large bowl, whisk the eggs, milk, sugar (or maple), vanilla, cinnamon, and salt until smooth and slightly frothy.
  4. Pour half the custard over the first bread layer and press gently to soak.
  5. Scatter half the blueberries over the soaked bread.
  6. Add the remaining bread cubes, pour the rest of the custard over and press lightly.
  7. Top with the remaining blueberries and cover with plastic wrap or foil. Refrigerate for at least 30 minutes, or up to overnight.
Baking
  1. Remove the cover and bake uncovered for 45 to 50 minutes, until golden brown and a knife inserted comes out mostly clean.
  2. Let the casserole rest for 5 minutes before slicing and serving warm.
