Ingredients

• 1 loaf of challah or brioche bread, cut into cubes
• 6 large eggs
• 2 cups milk (whole milk recommended for creaminess)
• 1/2 cup granulated sugar
• 1 teaspoon vanilla extract
• 1 teaspoon cinnamon
• 1/4 teaspoon nutmeg
• 1/2 cup turkey bacon, cooked and crumbled
• Cooking spray or butter for greasing the baking dish

How To Make Baked French Toast Casserole

Step 1: Prep Your Bread

Start by cutting your challah or brioche loaf into 1 to 1.5-inch cubes. These breads are ideal because they’re slightly sweet and have a tender crumb that absorbs the custard well without turning mushy. Spread the cubes evenly in a greased 9×13-inch baking dish.

Step 2: Cook and Crumble the Turkey Bacon

While the bread is ready, cook your turkey bacon until crisp. You can do this in a skillet over medium heat or in the oven. Once cooked, crumble the bacon into small pieces and set aside. This will add a savory crunch to your casserole.

Step 3: Make the Custard Mixture

In a large mixing bowl, whisk together the eggs, milk, granulated sugar, vanilla extract, cinnamon, and nutmeg until everything is well combined and smooth. This custard mixture is the flavor base of your casserole and will soak into the bread cubes.

Step 4: Combine and Soak

Pour the custard evenly over the bread cubes in the baking dish. Gently press the bread down with a spatula or your hands to ensure it soaks up as much liquid as possible. Sprinkle the crumbled turkey bacon evenly on top, gently pressing it into the mixture.

Step 5: Refrigerate Overnight (Optional but Recommended)

For best results, cover the casserole with plastic wrap and refrigerate overnight or at least 4 hours. This allows the bread to fully absorb the custard, resulting in a creamy, custardy texture once baked.

Step 6: Bake

Preheat your oven to 350°F (175°C). Remove the plastic wrap from the casserole and place it uncovered in the oven. Bake for 45 to 55 minutes, or until the top is golden brown and the custard is set. You can test doneness by inserting a knife into the center — it should come out clean.

Step 7: Serve

Allow the casserole to cool for about 10 minutes before serving. This dish pairs beautifully with maple syrup, fresh berries, or a dusting of powdered sugar. Enjoy warm!

Common Mistakes to Avoid

• Using bread that is too fresh – fresh bread can become soggy instead of custardy. Slightly stale challah or brioche works best.
• Skipping the soak time – allowing the bread to soak in the custard overnight ensures even texture and flavor throughout.
• Not cooking the turkey bacon fully – undercooked bacon can be chewy and overpower the casserole.
• Baking at too high a temperature – this can cause the edges to burn while leaving the center undercooked.
• Overcrowding the baking dish – using a dish that’s too small will result in uneven baking and soggy spots.

Variations and Customizations

• Make it vegetarian: Simply omit the turkey bacon or replace it with sautéed mushrooms or chopped nuts for added texture.
• Add fruit: Layer sliced apples, pears, or berries between the bread cubes before pouring the custard for a fruity twist.
• Use different spices: Swap nutmeg for cardamom or pumpkin pie spice to change up the flavor profile.
• Swap the sweetener: Replace granulated sugar with maple syrup or honey for a natural sweetness.
• Top it off: Before baking, sprinkle a mixture of brown sugar and chopped pecans on top for a crunchy streusel effect.

How to Store Leftovers

Store any leftover Baked French Toast Casserole covered in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or warm slices in a preheated oven at 325°F (160°C) until heated through. This casserole also freezes well — wrap individual portions tightly in plastic wrap and aluminum foil, then freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

FAQ

Can I use a different type of bread?

Absolutely! While challah and brioche are ideal for their texture and flavor, you can substitute other breads like French bread, Texas toast, or even whole wheat bread. Just make sure it’s sturdy enough to soak up the custard without disintegrating.

Can I make this recipe dairy-free?

Yes! Replace the milk with your favorite dairy-free alternative such as almond milk, oat milk, or coconut milk. Just be mindful of the flavor profile and sweetness level of the milk you choose, as it may affect the final taste slightly.

Is it possible to prepare this casserole without turkey bacon?

Definitely. You can omit the turkey bacon for a vegetarian version or replace it with a plant-based bacon alternative or even cooked sausage crumbles. You could also add chopped vegetables or nuts for added texture and flavor.

How long can I soak the bread in the custard mixture?

The bread can soak anywhere from 4 hours to overnight. The longer it soaks, the more custardy and flavorful the casserole will be. If you’re short on time, even 30 minutes can work, but the texture may not be as rich.
