French Toast Casserole:

  • 1 loaf of brioche bread (approximately 14 ounces, ‘day old’ best)
  • 8 eggs
  • 2 cups whole milk
  • ¾   cup heavy cream
  • ¾ cup sugar
  • 2 tablespoons vanilla
  • 1 teaspoon cinnamon
  • Butter for buttering the baking dish

Praline topping:

  • 1/2 cup flour
  • 1/2 cup brown sugar
  • 1/2 teaspoon nutmeg
  • 1/2 teaspoon cinnamon
  • 1/4 teaspoon salt
  • 1/2 cup cold butter, cubed
  • 3/4 cup pecans, chopped


  • Cube the bread. If it’s really fresh and still soft and fluffy, let it set out for a little while on a baking sheet.
  • Using 1 tablespoon of softened butter, ‘grease’ the baking dish then add the cubed brioche.
  • Whisk the eggs, milk, heavy cream, sugar, vanilla and cinnamon together then pour it evenly over the top of the bread.
  • Cover and refrigerate the casserole.
  • Blend the praline ingredients together using a fork. Store the praline in an airtight container until morning.
  • Before baking, crumble the praline onto the top of the casserole. Using your fingers, gently press down.
  • Bake at 375° for about 40 minutes or until it’s puffed and cooked through. The last 3-4 minutes of baking place the casserole dish to the lowest rack in the oven.
