Whether it’s slow-roasted in an oven or cooked over hot coals, prime rib is
never complete without horseradish and a little au jus. Horseradish makes a
perfect finish for your roast, whether you lean toward a prepared, creamy style
(often not too hot on the palate), or you prefer a freshly grated, sinus-blowing
experience. Use the drippings from your roasting pan — make sure you scrape up
all the little bits of rosemary and garlic that have accumulated — and a little
water to make a flavorful jus. You can also throw in a couple of the bones for
added flavor and richness to finish the sauce while your roast rests. If you
would rather eliminate this step, we recommend trying out Johnny’s French Dip Au
Jus. Happy roasting!
Ingredients
A combination of fresh flavors, such as fresh chopped garlic and rosemary
leaves
Kosher or sea salt and cracked black pepper to taste
Preparation
Cooking Tips:
Leave the roast cradled on the bone and in the net. Our rib roasts are ready
to cook: no trimming necessary and no need for a roasting rack!
Massage seasonings (we suggest simple, fresh flavors such as fresh garlic,
rosemary leaves, sea salt and cracked black pepper) all over the roast to form a
thin "crust".
After seasoning your roast, allow it to come to room temperature, about 2
hours, before placing it in the oven; this helps the roast cook evenly.
Estimate about 15-17 minutes per pound — the end cuts will be cooked to
medium and the center rare. Always use a meat thermometer to ensure the roast
has met your goal temperature! Digital read thermometers are the best and most
accurate.
Internal Temperature Guide:
a. Rare begins at 120°F
b. 125°F to 130°F for medium-rare
c. 140°F for medium
If cooking your roast on an outside grill, either charcoal or gas, use an
indirect heating method (the roast should not be placed directly over coals or
flame, but off to the side).
Cooking Method:
Set oven temperature to 450ºF. Roast meat for 15 minutes (to sear the
outside). Reduce oven temperature to 325ºF; continue roasting for the
appropriate time based upon the weight of the roast. Baste with drippings every
½ hour. Check internal temperature with a meat thermometer approximately 30-45
minutes before estimated end of cooking time.
Always allow roast to stand 20-30 minutes, tented with aluminum foil, before
carving. Internal temperature will raise another 5-10°F while the roast
rests.
