Pro tips to bake it like a brunch pro

Want your casserole to come out just right? Keep these in mind:

• Use slightly stale bread. It soaks up the custard better without turning to mush.
• Don’t skip the overnight soak. It gives the casserole its signature creamy interior.
• Let it sit for a few minutes after baking before cutting in, so it sets properly.
• For extra richness, mix in a few cubes of cream cheese before baking.
• A sprinkle of turbinado sugar on top before baking gives it a sweet, crunchy crust.

Gear up with these simple tools

You won’t need fancy gadgets to make this dish. Just a few essentials:

Large Mixing Bowl: For whisking your custard ingredients smoothly.

Whisk: Helps combine the eggs, milk, and flavorings with no lumps.

9×13 Baking Dish: The perfect size for a generous batch that bakes evenly.

Measuring Cups and Spoons: Precision is key for getting that sweet balance.

Spatula or Spoon: To mix and pour everything into the baking dish neatly.
