Ingredients

• 12 eggs: These act as the binder and provide a custard-like texture.
• 1 1/2 cups milk: Adds moisture to the casserole; use whole milk for best results.
• 2 tablespoons McCormick® Cinnamon, Ground, divided: Provides warmth and flavor. Substitute with 1 tablespoon cinnamon and 1 teaspoon nutmeg if needed.
• 1 tablespoon McCormick® Pure Vanilla Extract: Enhances the sweet notes. Use any pure vanilla extract.
• 1 loaf challah bread, cubed: The soft, airy texture is perfect for soaking; brioche would work too.
• 1/4 cup butter, melted: Helps brown the casserole and enriches flavor.
• 1/4 cup firmly-packed brown sugar: Sweetens the casserole and adds depth.
• 1 batch cream cheese icing: Adds a creamy finish. See below for details.
• 4 ounces cream cheese, softened: Forms the base of the icing; very important for smoothness.
• 1 cup powdered (confectioners’) sugar, sifted: Ensures a smooth, lump-free icing.
• 1 teaspoon McCormick® Pure Vanilla Extract: Adds rich flavor to the icing.
• 1-3 teaspoons milk, as needed: Adjusts the icing’s consistency.

How to Make It

Step 1: Prepare the Custard

In a large mixing bowl, whisk together the eggs, milk, 1 tablespoon of cinnamon, and vanilla extract until fully combined. This mixture will permeate the bread, creating a moist, flavorful base.

Step 2: Assemble the Casserole

Submerge the cubed challah bread in the custard mix, ensuring each piece is thoroughly soaked. Pour the mixture into a greased 9×13-inch baking dish. Cover the top with melted butter, then sprinkle with brown sugar and the remaining cinnamon for a sweet, spicy crust.

Step 3: Refrigerate Overnight

Cover the dish with plastic wrap and refrigerate overnight. This resting period allows the bread to fully absorb the custard, enhancing flavor and texture.

Step 4: Bake the Casserole

Preheat your oven to 350°F (175°C). Remove the plastic wrap and bake the casserole for 30-35 minutes, or until golden brown. The edges should be firm while the center remains slightly soft.

Step 5: Prepare and Add the Icing

While the casserole bakes, make the icing by beating the cream cheese, sifted powdered sugar, and vanilla extract until smooth. Gradually add milk to reach your desired consistency. Drizzle the cream cheese icing over the warm casserole, allowing it to melt and spread.

Recipe FAQs

Can I use a different kind of bread?

Yes, while challah bread offers a unique texture, brioche or a sturdy white bread can serve as excellent substitutes due to their similar absorbent qualities.

How can I store leftovers?

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at a lower temperature to maintain the texture without drying it out.

Can I make the icing ahead of time?

Absolutely. Prepare the icing up to two days in advance and store in the refrigerator. Allow it to soften slightly at room temperature before drizzling over the casserole.
