Easy Overnight Cinnamon Roll French Toast Casserole

A cozy, hands-off breakfast casserole made by soaking cinnamon rolls in a cinnamon-spiced custard overnight and baking to a golden, custardy perfection.

Ingredients

Scale
  • 8 to 10 store-bought cinnamon rolls (classic refrigerated kind or homemade)
  • 6 large eggs, room temperature
  • 2 cups (480 ml) whole milk or 2% milk (almond or oat milk for dairy-free)
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon (plus extra for sprinkling)
  • 2 tablespoons packed brown sugar
  • A pinch of salt
  • 2 tablespoons melted butter (for greasing the dish)
  • Optional toppings: powdered sugar, maple syrup, cream cheese glaze (cream cheese, powdered sugar, splash of milk)

Instructions

  1. Unwrap cinnamon rolls and cut into roughly 1-inch chunks. Place evenly in a buttered 9×13-inch baking dish.
  2. In a large bowl, whisk together eggs, milk, vanilla extract, ground cinnamon, brown sugar, and salt until fully combined and slightly frothy.
  3. Pour custard mixture evenly over cinnamon roll chunks. Gently press down to help rolls soak up custard. Cover tightly with plastic wrap or foil.
  4. Refrigerate covered for at least 6 hours or overnight to allow rolls to absorb custard.
  5. Preheat oven to 350°F (175°C). Remove plastic wrap and bake uncovered for 45 to 55 minutes until top is golden brown and casserole is set (toothpick should come out mostly clean).
  6. Let casserole rest for about 10 minutes before serving to set further and ease cutting.
  7. Add optional toppings such as powdered sugar, maple syrup, or cream cheese glaze just before serving.

Notes

Do not skip the overnight soak to avoid doughy centers. Use cinnamon rolls with or without icing; make your own glaze for better sweetness control. Butter the dish well to prevent sticking and add richness. Check oven around 40 minutes if it runs hot to prevent over-browning. For a fluffier texture, let cinnamon rolls thaw fully before cutting.
