Whether you're hosting or attending to a potluck Super Bowl party this year, having a make-ahead recipe or two up your sleeve is a must. Sure, it might not be the big game without some of the day-of treats, like baked spinach-artichoke dip or buffalo chicken wings, but it makes all the difference if most of the menu can be ready to go when the game starts. (That is, unless you aren't particularly into the game and enjoy hiding away in the kitchen for much of it.) These 42 recipes fit the bill; many can be made ahead in their entirety and served at room temperature, while others need only a finishing touch or to be reheated at party time. Nearly all are delightfully decadent.
