For holiday meals when there are many dishes to manage, go ahead and prep the Brussels sprouts up to the point where you pop them into the oven. Instead, cover with foil and refrigerate. When it's time to cook, just pop them into the preheated oven. If your oven schedule is tight, roast the Brussels sprouts per the recipe and then pop them into an airfryer right before serving to heat through and bump up the crispiness.
