Yes, cube it and spread it on a baking sheet and let it sit for at least a day. And don't worry, even if you let it sit out until Thanksgiving day, it wouldn't be too stale. For future stuffing making, you can also cheat this by letting the bread cubes toast in a 200-degree oven until they're firm and dry.

I like to cube the bread and toast it for a bit in the oven. If you get it nice and dried out then it can absorb all the delicious flavors of the stuffing. You don't have to get the bread crouton like, just dry it out a bit.
