Jo Cooks creates a simple blend of garlic, rosemary, chili flakes, and olive oil to make her show-stopping Roast Pork with Rosemary and Garlic. The 10-minute prep time is perfect for busy holiday party hosts, as you can slather on the fragrant oil rub, park the roast in the oven for three hours, and carry on with the remaining courses of your festive spread.
