What says the holidays better than a delicious Prime Rib or Cross Rib Roast with Horseradish sauce. The original recipe for closed door cooking of the Prime Rib came from Colorado Cache Cookbook, still my all-time favorite cookbook.  We have served this recipe many times, always a big hit.

This time, however, the balsamic vinegar and rub were new and I loved the results.

ROAST BEEF PERFECTION

1 Prime Rib or Cross Rib Roast, any size
3 tablespoons Balsamic vinegar
3 tablespoons fresh minced garlic
2 tablespoons fresh thyme leaves, removed from stems and chopped
2 tablespoons fresh rosemary leaves, removed from stems and chopped
1 tablespoon coarse sea or kosher salt
Freshly-ground black pepper
1 tablespoon olive oil

• Preheat oven to 375 degrees.  Place Prime Rib in roasting pan and brush with Balsamic vinegar.  Make a paste of the garlic, thyme, rosemary, salt, pepper and olive oil.  Rub paste mixture over the roast.

• Place roast in oven and cook for 1 hour.  Turn the oven off and KEEP THE OVEN door closed.
• 45 minutes before serving, turn the oven to 300 degrees. Remove from oven and rest for 5-10 minutes.  The roast will be juicy medium-rare and perfect every time. If you like your Prime Rib cooked to medium, just add 15-20 minutes to the initial cooking time.

Horseradish Sauce

1 cup sour cream
1 tablespoon grated onion
1 1/2 tablespoon Dijon mustard
3 teaspoons prepared horseradish

• Stir together and refrigerate until serving time.
