Prime Rib is a classic beef roast, so the pairing options for sides are extensive! Try classic vegetables like Creamed Spinach, Roasted Brussels Sprouts, Mashed Potatoes, Sauteed Green Beans, Roasted Carrots and Root Veggies. Go with something unique like Cauliflower Puree, Drunken Mushrooms, Winter Squash, and Toasted Nuts, Swiss Chard. And of course, don’t forget the sauces. Prime Rib goes especially well with a dollop of Horseradish on the side and some Red Wine Sauce drizzled on top! (Don’t get too rich with sauces, though. The meat is already rich and flavorful as is. You might overwhelm your palate.)
