Here's a recipe that I normally make in a Dutch Oven but you could easily put it in a 9x13 on throw on a smoker.
Praline French Toast
1 loaf French bread
8 large eggs
2 cups whipping cream
1 cup milk
1/4 cup sugar
1 teaspoon vanilla extract
1 teaspoon cinnamon
1/2 teaspoon nutmeg
Praline Topping
2 sticks butter
1 cup packed brown sugar
2 tablespoons light corn syrup
1 teaspoon cinnamon
1 teaspoon nutmeg
2 cups chopped pecans
Slice French bread into 20 1-inch slices. In a bowl or a 2-gallon plastic ziptop bag, mix the eggs, whipping cream, milk, sugar, vanilla, cinnamon and nutmeg. Make sure it is well blended. Add bread slices and soak overnight in the refrigerator or cooler. (If you don't have a 2 gallon bag, divide the mixture into two 1-gallon bags).
In the morning, melt the butter, brown sugar, corn syrup, cinnamon and nutmeg in the bottom of a 14-inch oven. Be careful not to scorch.
When melted, add chopped pecans and toss to coat. Disperse evenly over the bottom of the oven and top with French bread slices. Pour any remaining egg mixture over bread. Bake at 350 degrees for 30 to 40 minutes or until golden brown. Serve with warm syrup.
