Why This Recipe Works

After testing dozens of versions, we’ve perfected the formula for French toast casserole that’s:

• Consistently custardy without being eggy
• Golden and crisp on top
• Flavor-balanced (not too sweet)
• Versatile for various diets and preferences

Key innovations:

• The right bread-to-custard ratio (most recipes use too much liquid)
• Dual soaking method for maximum flavor penetration
• Broiler finish for perfect caramelization
• Resting time for ideal texture

The Secret of Great French Toast Casserole

Understanding these principles will make you a better breakfast cook:

Bread Selection & Preparation

• Starch retrogradation: Stale bread absorbs better because its starch molecules have recrystallized
• Ideal porosity: Brioche and challah have the perfect crumb structure
• Surface area: Cubed vs. sliced – why we prefer cubes

Custard Chemistry

• Egg proteins coagulate at different temperatures
• Sugar’s role beyond sweetness (it affects browning)
• Fat content matters – why whole milk beats skim

The Maillard Reaction

How heat transforms your casserole into a flavor powerhouse

Ingredients: Quality Matters

*(Serves 10-12 generously)*

The Bread (Choose Wisely!)

• 2 lbs (about 16 cups) brioche (our top pick)
• Excellent alternatives:
  • Challah
  • French bread
  • Panettone (for holiday version)
  • Croissants (extra rich)
  • Gluten-free brioche (King Arthur makes a great one)

The Custard (The Flavor Foundation)

• 8 large eggs (room temperature blends better)
• 3 cups whole milk (or 2 cups milk + 1 cup heavy cream)
• ¾ cup granulated sugar (or ½ cup white + ¼ cup brown)
• 1½ tbsp vanilla extract (use real vanilla bean paste for luxury)
• 2½ tsp ground cinnamon
• ½ tsp freshly grated nutmeg
• ½ tsp sea salt (balances sweetness)
• 2 tbsp bourbon or rum (optional flavor booster)

The Crunchy Topping

• 6 tbsp unsalted butter, melted
• ⅓ cup brown sugar
• 1½ tsp cinnamon
• ¼ tsp cardamom (secret flavor enhancer)

Optional Mix-ins (Choose 1-2)

• 2 cups seasonal fruit (berries, apples, pears)
• 1 cup toasted nuts (pecans, walnuts, almonds)
• ¾ cup chocolate chips or chunks
• ½ cup dulce de leche or caramel sauce
• Zest of 1 orange (brightens flavor)

Step-by-Step Instructions with Pro Techniques

Day Before: Prep & Soak

1. Prepare the Bread
   • Cut into 1½-inch cubes (larger pieces hold texture better)
   • Spread on baking sheet
   • Toast at 275°F for 15 minutes if using fresh bread
2. Make the Custard
   • In large bowl, whisk eggs until uniform
   • Gradually add milk while whisking
   • Incorporate sugar, vanilla, spices, and salt
   • Pro Tip: Warm milk slightly (110°F) to help sugar dissolve
3. First Soak (Critical Step!)
   • Place half the bread in greased 9×13″ dish
   • Pour half the custard over, pressing down gently
   • Add remaining bread and custard
   • Cover with plastic wrap pressed directly on surface
   • Refrigerate 1 hour
4. Second Soak
   • Remove from fridge
   • Using clean hands, gently turn and mix bread
   • Recover and refrigerate overnight (8-12 hours ideal)

Baking Day

1. Preheat & Prep
   • Remove casserole from fridge 30 minutes before baking
   • Preheat oven to 325°F (lower temp prevents curdling)
   • Make topping: mix melted butter, brown sugar, and spices
2. Bake to Perfection
   • Uncover casserole
   • Drizzle topping evenly over surface
   • Bake 50 minutes
   • Increase temp to 375°F, bake 10 more minutes
   • Broil 2-3 minutes until deeply caramelized
3. Rest & Serve
   • Let stand 15 minutes (allows custard to set)
   • Dust with powdered sugar
   • Serve with warm maple syrup and fresh berries

Chef’s Secret Techniques

1. The Double Soak Method
   • First soak hydrates the bread
   • Second soak ensures even distribution
   • Eliminates dry spots
2. Temperature Control
   • Starting at lower temp prevents rubbery eggs
   • Final high heat creates perfect texture contrast
3. The Butter Trick
   • Adding melted butter to topping (not just on top)
   • Creates crispy, candy-like crust

This make-ahead French Toast Casserole is perfect for holiday mornings or weekend brunches. Cubes of bread are soaked overnight in a rich custard mixture, then baked until golden and puffy. It’s like having French toast for a crowd without the hassle of cooking individual slices!

Ingredients

For the Casserole:

• 1 loaf (16 oz) day-old French bread or brioche, cut into 1-inch cubes

• 8 large eggs

• 2 cups whole milk

• 1/2 cup heavy cream

• 1/4 cup granulated sugar

• 1/4 cup brown sugar, packed

• 1 tablespoon vanilla extract

• 1/2 teaspoon ground cinnamon

• 1/4 teaspoon ground nutmeg

• 1/4 teaspoon salt

• 2 tablespoons butter, melted

• For the Topping:

• 1/2 cup all-purpose flour

• 1/2 cup brown sugar, packed

• 1/2 teaspoon ground cinnamon

• 1/4 teaspoon salt

• 1/2 cup cold butter, cubed

• 1/2 cup chopped pecans (optional)

Directions

Preparation (Night Before):

• Prepare the dish: Grease a 9×13-inch baking dish with butter or cooking spray.
• Prepare bread: Cut day-old bread into 1-inch cubes and arrange evenly in the prepared baking dish.
• Make custard mixture: In a large bowl, whisk together eggs, milk, heavy cream, granulated sugar, brown sugar, vanilla extract, cinnamon, nutmeg, and salt until well combined.
• Assemble: Pour the custard mixture evenly over the bread cubes, making sure all pieces are coated. Press down gently with a spatula to help bread absorb liquid.
• Chill overnight: Cover tightly with plastic wrap and refrigerate for at least 4 hours or overnight.
• Baking Day:
• Preheat oven: Remove casserole from refrigerator 30 minutes before baking. Preheat oven to 350°F (175°C).
• Make topping: In a small bowl, combine flour, brown sugar, cinnamon, and salt. Cut in cold butter using a pastry cutter or fork until mixture resembles coarse crumbs. Stir in pecans if using.
• Add topping: Remove plastic wrap and sprinkle the crumb topping evenly over the casserole.
• Bake: Bake for 45-50 minutes, or until center is set and top is golden brown. If top browns too quickly, cover with foil.
  
• Rest and serve: Let cool for 5-10 minutes before serving. Serve warm with maple syrup, powdered sugar, or fresh berries.

Notes

• Best bread to use: Day-old or slightly stale bread works best as it absorbs the custard without falling apart. French bread, brioche, challah, or thick-cut Texas toast all work well.
  Make-ahead tip: This recipe is designed to be made the night before, making it perfect for busy mornings.
  Texture tip: For extra richness, substitute half-and-half for the milk.
  Flavor variations: Add 1/2 cup fresh blueberries, sliced strawberries, or chocolate chips to the bread before adding custard.
  Storage: Leftovers keep in the refrigerator for up to 3 days and can be reheated in the microwave or oven.
  Freezing: Can be frozen (before baking) for up to 2 months. Thaw overnight before baking, adding 10-15 extra minutes to bake time.
