Ingredients

Scale
  • 8 tablespoons unsalted butter, divided
  • 6 large eggs
  • 2 cups half-and-half
  • 3/4 cup apple butter
  • 1 1/2 teaspoons ground cinnamon, divided
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon freshly grated nutmeg
  • 1/4 teaspoon fine salt
  • 1 (1-pound) loaf challah or brioche, cut into 1-inch-thick slices
  • 2 large Pink Lady or Honeycrisp apples, cut into 1/2-inch cubes (about 4 cups)
  • 2 tablespoons granulated sugar
  • 1/2 cup all-purpose flour
  • 1/2 cup granulated sugar for the topping
  • 1 teaspoon ground cinnamon for the topping
  • Powdered sugar and warm maple syrup, optional for serving

Instructions

  1. Brush a 9-by-13-inch baking dish with some melted butter. Whisk the remaining melted butter, eggs, half-and-half, apple butter, 1/2 teaspoon cinnamon, vanilla, nutmeg, and salt.
  2. Dip each bread slice in custard and arrange slightly overlapping in four alternating rows in the dish.
  3. Toss apple cubes with 2 tablespoons sugar and the remaining 1 teaspoon cinnamon. Tuck them around and between the bread, then pour remaining custard evenly over everything.
  4. Whisk flour, 1/2 cup sugar, and topping cinnamon. Cut in 4 tablespoons cold butter until crumbly, scatter over the casserole, cover, and refrigerate overnight for up to 24 hours.
  5. Uncover while the oven heats to 350°F. Bake 35 to 40 minutes until puffed, golden, and set in the center. Rest briefly and serve with optional powdered sugar or warm maple syrup.

Notes

  • Use slightly dry bread so it absorbs custard without losing all structure.
  • Distribute apple cubes into every open space for fruit in each serving.
  • Keep topping butter cold so the crumbs remain distinct rather than melting into a paste.
  • Nutrition information is an estimate calculated per serving and may vary by ingredient brand and portion size.
