Cut the bread into 1-inch cubes and place in a very large bowl or spread out on a baking sheet to sit out for 24 hours.
1 pound Loaf of day-old French bread, cut into 1" cubes
Butter a 9 x 13 baking dish. Set aside.
In a large bowl whisk the eggs to blend. Add the milk, cream, sugar, vanilla, cinnamon, nutmeg, and salt. Whisk to combine thoroughly.
8 large Eggs, 3 1/2 cups Whole milk, 1 1/2 cups Heavy whipping cream, 1 1/2 cups Granulated sugar, 2 tsp Vanilla extract, 1 tsp Ground cinnamon, 2 tsp Pumpkin pie spice, 1/2 tsp Kosher salt, 1 15oz Pumpkin puree
Toss the pecans on top of the bread cubes. Pour the egg mixture over the cubed bread and stir to coat and blend evenly. Pour into the buttered baking dish spread out evenly, and press down for a more uniform slice or leave as is for crusty edges on top. Cover and refrigerate at least 4 hours to overnight. (overnight preferred)
3/4 cup Pecans
