Preheat your oven to 350 degrees F.
Butter or spray an 8x8 or 9x9 baking dish and layer the bottom of the dish with half of the bread cubes.
Scatter half of the sliced peaches over the bread cubes.
Repeat steps 2 & 3 with the remaining half of the bread cubes and peaches.
In a large bowl, whisk together the cream, milk, eggs, vanilla extract, cinnamon, nutmeg, and salt.
Pour the egg/cream mixture over the bread cubes and peaches.
Gently toss the mixture to ensure that the bread is evenly saturated with the liquid.
Bake for an hour or until the casserole is golden brown on top and set in the center, with no liquid remaining in the bottom of the dish.
Slice into squares and serve hot with your favorite toppings.
