Helpful Tips for the Best Prime Rib with Garlic

• Invest in a meat thermometer: Accuracy matters when cooking such a fine cut. This ensures the perfect doneness.
• Let the meat rest: Resting allows juices to redistribute for a juicier roast.
• Use fresh herbs: Rosemary and thyme add depth, though the roast is still delicious even without them.
• Make the sauce ahead: Prepare the horseradish sauce several hours before serving to let flavors meld beautifully.
• Serve with balance: Pair with rich sides like mashed potatoes and a vibrant green veggie for color and freshness.
