I store it on top of the toaster oven will a paper towel over it. Sorry you burned your bread crumbs, OP.

Put it in the freezer.

be used for stuffing, either don’t store it out of the way in the oven, or, if you do use the oven, remember to pull it out before turning the oven on. This is what I’ll have to tell myself next time I make stuffing, I guess.
