Spread butter over bottom of large baking pan with 1-inch-high sides. Arrange bread slices in one layer across pan.
Beat eggs, milk, syrup, vanilla, orange juice, zest, and salt in large bowl. Pour mixture over bread so that each piece is covered. Turn bread slices to coat. Cover with plastic wrap and refrigerate overnight.
Preheat oven to 400 F. (Or, you can pan-fry it the traditional way.) Bake bread for 10 minutes. Turn bread over and continue baking until just golden, about 4 minutes longer. Transfer cooked toast to plates and sprinkle with powdered sugar.
Serve immediately with all-natural maple syrup, pecans, and berries.
Preparation time: 20 minutes (not including marinating time)
