Cozy Cinnamon Roll French Toast Casserole

Cinnamon Roll French Toast Casserole - featured image

A quick and easy breakfast casserole that transforms store-bought cinnamon rolls into a gooey, custardy delight perfect for lazy weekends or brunch gatherings.

Ingredients

Scale
  • 8 large store-bought cinnamon rolls (preferably with icing included)
  • 6 large eggs, room temperature
  • 2 cups whole milk (480 ml)
  • 1 cup heavy cream (240 ml)
  • ½ cup granulated sugar (100 g)
  • 2 teaspoons ground cinnamon
  • 2 teaspoons pure vanilla extract
  • ¼ teaspoon salt
  • 2 tablespoons butter, melted (for greasing the baking dish)

Instructions

  1. Preheat your oven to 350°F (175°C). Butter your 9×13-inch baking dish generously to prevent sticking and add richness to the crust.
  2. Unroll the cinnamon rolls and slice each roll into 3 equal pieces to keep the gooey swirls visible after baking.
  3. Arrange the cinnamon roll pieces in the baking dish, flat side down, packing them close but not squished.
  4. In a large mixing bowl, whisk together 6 large eggs, 2 cups whole milk, 1 cup heavy cream, ½ cup granulated sugar, 2 teaspoons ground cinnamon, 2 teaspoons vanilla extract, and ¼ teaspoon salt until fully combined and slightly frothy.
  5. Pour the custard evenly over the arranged cinnamon rolls. Gently press the pieces down so the custard seeps into every nook.
  6. Cover the dish with aluminum foil and refrigerate for at least 30 minutes, or overnight for best results.
  7. Remove the foil and bake the casserole in the preheated oven for 35-40 minutes, or until the top is golden brown and the custard is set (a knife inserted near the center should come out clean).
  8. Optional: In the last 5 minutes, drizzle the included icing over the top or make a quick glaze by mixing powdered sugar and a splash of milk. Return to oven briefly to warm the icing.
  9. Remove from oven and let rest for about 10 minutes before serving.

Notes

Do not skip the soaking step; refrigerate the casserole for at least 30 minutes or overnight to allow the custard to fully penetrate the dough. Tent with foil if edges brown too quickly. Use room-temperature eggs and dairy for best custard texture. Butter the baking dish generously to prevent sticking.
