Planning a prime rib meal for Christmas or any big gathering and wondering what deserves a spot beside that juicy prime rib roast?
You can lean into timeless classics—like pillowy mashed potatoes, golden Yorkshire pudding, caramelized vegetables, or rich, buttery mushrooms—or you can bring some fresh twists to the table to make your menu feel extra celebratory.
Prime rib isn’t exactly a weeknight throw-together dish. It’s a centerpiece that announces “this is a special moment,” so the accompaniment you choose should elevate the occasion, look stunning on the table, and taste just as impressive as the roast itself.
But crafting that memorable spread doesn’t have to be complicated.
With the best side dishes selected to complement your gorgeous roast, your entire prime rib feast will come together beautifully—and I’ve got plenty of ideas to help you make it unforgettable.
