Choosing the Right Bread for French Toast Casserole

Best Breads for This Recipe

The foundation of an excellent French toast casserole is the bread. Day-old bread works best as it absorbs the custard mixture without becoming soggy. My top recommendations:

Brioche: Creates the richest, most decadent result
Challah: Slightly sweet with perfect density
French bread: Offers more structure and chew
Texas toast: Thick-cut white bread for a classic approach

Bread Preparation Tips

For the best French toast casserole, your bread should be slightly stale. If you only have fresh bread, here’s what to do:

Cut bread into 1-inch cubes and spread on baking sheet
Leave uncovered at room temperature for 3-4 hours or overnight
Alternatively, toast bread cubes in a 275°F oven for 10 minutes

Substitutions

Don’t have the ideal bread? No problem! Try these alternatives:

Croissants: Create an ultra-buttery, decadent casserole
Cinnamon raisin bread: Adds built-in flavor and sweetness
Sourdough: Provides a slight tanginess that balances the sweet custard

Step-by-Step French Toast Casserole Instructions

Pre-Cooking Prep for French Toast Casserole

Grease a 9×13-inch baking dish with butter or cooking spray.
Arrange bread cubes evenly in the prepared baking dish.
In a large bowl, whisk together eggs, milk, cream, sweetener, vanilla, cinnamon, nutmeg, and salt until well combined.
Pour the custard mixture evenly over the bread, gently pressing down to ensure all pieces are soaked.

Baking Your French Toast Casserole

For immediate baking: Preheat oven to 350°F. Let the casserole sit for 15-20 minutes to absorb the custard while the oven heats.
For overnight prep: Cover dish with plastic wrap and refrigerate for 8-12 hours.
If refrigerated, remove casserole from refrigerator 30 minutes before baking.
Sprinkle with streusel topping if using.
Bake uncovered for 45-55 minutes until center is set and top is golden brown.

Doneness Check for French Toast Casserole

The perfect French toast casserole should be:

Golden brown on top
Set in the center (not jiggly)
Reach an internal temperature of 160°F
Spring back slightly when gently pressed

Resting Your French Toast Casserole

Allow the casserole to rest for 10-15 minutes before serving. This helps the custard set completely and makes cutting cleaner slices easier.

Pro Tips for Perfect French Toast Casserole

Avoiding Soggy French Toast Casserole

Use stale or dried bread that will absorb custard without falling apart
Don’t oversoak – bread should be moistened but not swimming in liquid
Ensure proper bread-to-custard ratio (approximately 1 cup custard per 2 cups bread)

Kitchen Tool Recommendations

Glass baking dish for even heating
Whisk for thoroughly combining custard ingredients
Serrated knife for clean slicing
Offset spatula for serving

Storage & Reheating French Toast Casserole

Refrigerate leftovers covered for up to 4 days
Reheat individual portions in microwave for 60-90 seconds
Reheat larger portions covered in 350°F oven for 15-20 minutes
Freeze baked casserole for up to 2 months

FAQs About French Toast Casserole

Can I make French toast casserole ahead of time?

Absolutely! This recipe is perfect for prepping the night before. Assemble everything, cover, and refrigerate overnight. In the morning, let it sit at room temperature for 30 minutes while the oven preheats, then bake as directed.

How do I know when my French toast casserole is done?

The casserole is done when the center is set and not jiggly, the top is golden brown, and an inserted knife comes out clean. The internal temperature should reach 160°F.

Can I freeze French toast casserole?

Yes! You can freeze it either before or after baking. To freeze before baking, assemble the casserole, cover tightly, and freeze for up to 2 months. Thaw overnight in the refrigerator before baking. For baked casserole, cool completely, wrap well, and freeze for up to 2 months.

My casserole turned out soggy. What went wrong?

Soggy casserole usually means either the bread was too fresh and didn’t absorb enough custard, or the casserole was underbaked. Try using staler bread or baking a bit longer next time.
