Ingredients

For the Prime Rib:\
* 3-4 pound boneless prime rib roast (2-3 ribs)\
* 2 tablespoons olive oil\
* 4 cloves garlic, minced\
* 2 tablespoons fresh rosemary, chopped\
* 1 tablespoon fresh thyme, chopped\
* 1 tablespoon coarse sea salt\
* 1 teaspoon black pepper
For the Garlic Mashed Potatoes:\
* 2 pounds Russet or Yukon Gold potatoes, peeled and quartered\
* 6 cloves garlic, peeled\
* 1/2 cup whole milk, warmed\
* 1/2 cup unsalted butter, softened\
* 1/4 cup sour cream (optional)\
* Salt and freshly ground black pepper to taste\
* Fresh chives, chopped, for garnish
Step-by-Step Instructions

1. Prepare the Prime Rib: Pat roast dry. Combine olive oil, minced garlic, rosemary, thyme, sea salt, and black pepper into a paste. Rub generously over the roast. Place on a rack in a roasting pan; let sit at room temperature for 1-2 hours for even cooking.
2. Roast the Prime Rib: Preheat oven to 450°F (230°C). Roast for 15 minutes to develop a crust. Reduce oven to 325°F (160°C); continue roasting. For medium-rare, aim for an internal temperature of 120-125°F (49-52°C), typically 12-15 minutes per pound.
3. Rest the Meat: Once target temperature is reached, remove from oven, transfer to a carving board, and tent with foil. Rest for a crucial 20-30 minutes. This allows juices to redistribute, ensuring a tender, flavorful roast.
4. Make Garlic Mashed Potatoes: While prime rib rests, place peeled, quartered potatoes and whole garlic cloves into a large pot. Cover with cold, salted water; bring to a boil. Cook until fork-tender, about 15-20 minutes. Drain thoroughly.
5. Mash and Season: Return drained potatoes and garlic to the hot pot. Add warmed milk, softened butter, and sour cream (if using). Mash until smooth and creamy. Season generously with salt and pepper.
6. Serve: Slice the rested prime rib against the grain into thick, juicy portions. Serve immediately with garlic mashed potatoes, garnished with fresh chives.
Expert Tips
For spectacular prime rib, consider reverse searing: start at a lower oven temperature (250°F/120°C) until 10 degrees below target, then blast at 450°F (230°C) for 10-15 minutes to crisp the exterior. Always use a reliable meat thermometer. When mashing potatoes, avoid overworking to prevent a gluey texture; gentle mashing or ricing is key. Warm milk and softened butter ensure smooth incorporation without cooling spuds.
Variations
Elevate your prime rib rub with smoked paprika or a pinch of dried chili flakes. For mashed potatoes, try cream cheese for a richer tang, or swirl in roasted red pepper pesto for vibrant color and flavor. A sprinkle of grated Parmesan cheese adds savory depth.

Conclusion
This Anniversary Prime Rib Dinner is more than a meal; it’s an experience crafted with love. The golden-brown crust, tender, rosy interior of the prime rib, and cloud-like garlic mashed potatoes create a symphony of flavors. Savor each bite and enjoy the precious moments shared around the table. Here’s to many more delicious anniversaries!
