INGREDIENTS

• 1 loaf French bread (day-old or slightly stale), cut into cubes
• 6 large eggs
• 2 cups whole milk
• ½ cup heavy cream
• ½ cup granulated sugar
• ¼ cup brown sugar
• 1 tablespoon vanilla extract
• 1 teaspoon ground cinnamon
• ¼ teaspoon salt
• 2 tablespoons butter, for greasing
• Maple syrup and powdered sugar, for serving (optional)

DIRECTIONS

• Step No.1: Prepare the dish
  Grease a 9x13-inch baking dish with butter. Cut the bread into 1-inch cubes and spread evenly in the prepared dish.

• Step No.2: Make the custard
  In a large bowl, whisk together eggs, milk, cream, both sugars, vanilla, cinnamon, and salt until smooth and fully combined.

• Step No.3: Pour and soak
  Pour the custard mixture evenly over the bread cubes, pressing down gently to help them soak. Cover with foil or plastic wrap.

• Step No.4: Refrigerate overnight
  Place the dish in the fridge and let it chill overnight. This allows the bread to soak up the custard thoroughly.

• Step No.5: Bake the casserole
  Preheat oven to 175°C (350°F). Uncover the dish and bake for 45–50 minutes, until golden and the centre is set.

TIPS FOR SUCCESS

• Use Stale Bread: Slightly dry bread holds up better and soaks in the custard without turning soggy or mushy.

• Grease Thoroughly: Butter the baking dish well to prevent sticking and create a golden crust on the edges.

• Let It Soak Fully: Refrigerate for at least 8 hours to let the bread absorb all the delicious flavours of the custard.

• Top Before Baking: Add fruit, nuts, or streusel on top before baking for extra texture and taste.

• Check Centre for Doneness: Insert a knife into the centre—if it comes out clean, the casserole is ready.

• Let It Rest: Allow the casserole to cool for 10 minutes before serving so it slices neatly and holds its shape.

• Serve With Toppings: Maple syrup, powdered sugar, whipped cream, or berries make it feel extra special and complete.

VARIATIONS

• Berry Delight: Add fresh or frozen berries between the bread layers or on top before baking for fruity bursts.

• Nut Crunch: Sprinkle chopped pecans, almonds, or walnuts on top for crunch and a nutty contrast to the custard base.

• Chocolate Swirl: Mix in mini chocolate chips or drizzle chocolate syrup for a sweet, dessert-like version.

• Apple Cinnamon: Add sliced apples and an extra pinch of cinnamon for a comforting, pie-inspired breakfast.

• Savoury Twist: Skip the sugar and cinnamon, and add cheese, herbs, and cooked sausage for a savoury version.

• Pumpkin Spice: Stir in ½ cup pumpkin purée and pumpkin spice for a fall-themed variation that’s warm and fragrant.

• Cream Cheese Layer: Dot with cream cheese cubes for a tangy contrast and creamy bites throughout the casserole.
