A cozy and crowd-pleasing breakfast casserole featuring custardy soaked bread topped with a crunchy cinnamon streusel. Perfect for busy mornings or special gatherings.

Ingredients

Scale
  • 8 cups day-old bread cubes (about 10 slices of thick-cut bread like brioche or challah)
  • 6 large eggs, room temperature
  • 2 cups whole milk (or any milk of choice; almond or oat milk work well for dairy-free)
  • 1/2 cup heavy cream (adds richness but can be swapped for extra milk)
  • 1/2 cup granulated sugar
  • 2 tsp vanilla extract
  • 1 tsp ground cinnamon
  • 1/4 tsp salt
  • 1/2 cup all-purpose flour
  • 1/3 cup brown sugar (packed)
  • 1 tsp ground cinnamon
  • 1/4 tsp nutmeg (optional)
  • 6 tbsp unsalted butter, cold and cubed
  • Pinch of salt

Instructions

  1. Cube your day-old bread into roughly 1-inch pieces and spread evenly in a greased 9×13 inch baking dish.
  2. In a medium bowl, whisk together eggs, milk, heavy cream, sugar, vanilla extract, cinnamon, and salt until smooth.
  3. Pour the custard mixture evenly over the bread cubes and gently press down to help bread absorb the custard. Do not stir.
  4. Cover the dish with plastic wrap and refrigerate for at least 4 hours or overnight.
  5. In a small bowl, mix flour, brown sugar, cinnamon, nutmeg (if using), and salt. Add cold cubed butter and use a pastry cutter or fingers to mix until coarse crumbs form.
  6. Preheat oven to 350°F (175°C).
  7. Sprinkle the streusel evenly over the soaked bread and bake uncovered for 45-50 minutes until the top is golden brown and custard is set.
  8. Let the casserole cool for 5-10 minutes before serving.

Notes

Use day-old bread for best texture; stale bread soaks custard better without becoming mushy. Resting overnight is crucial for custardy texture. If streusel browns too fast, tent with foil halfway through baking. For gluten-free, substitute flour with almond or gluten-free flour. For dairy-free, use coconut oil instead of butter and plant-based milk.
