Ingredients
- 4 tablespoons butter softened
- 1 tablespoon orange zest
- 1 tablespoon rosemary minced
- ¼ teaspoon ginger minced
- 3 cloves garlic minced
- 1 ½ teaspoons brown sugar
- 1 teaspoon soy sauce
- 1 teaspoon pepper
- 1 teaspoon salt
- 6 pound prime rib roast about 3-4 ribs
- 3 cups water
Instructions
- Preheat oven to 450ºF.
- Combine butter, ginger, orange zest, garlic, salt, pepper, soy sauce, brown sugar, and rosemary.
- Spread butter rub over the prime rib and place on a roasting rack in a roasting pan (see note).
- Add water to the bottom of the roasting pan.
- Roast at 450ºF for 20 minutes.
- Reduce the oven temperature to 325º F and continue to roast until medium-rare (130-135ºF), about 1.5 hours. Check the water in the roasting pan and the temperature of the prime rib roast after about 1-hour, adding more water if necessary.
- Remove the prime rib roast from the oven and let it rest for 15-20 minutes before slicing and serving.
- Cut and remove the strings and slice the prime rib, or remove the bottom bones (they will just slide off) if you want to serve thinner slices.

Notes
- You can use 3 balls of foil to elevate the roast in the pan if you don't have a rack.
- If you're lucky enough to have leftovers, they transform beautifully into next-day prime rib sandwiches, hash, or thinly sliced for salads – giving busy moms multiple meals from one cooking session.
- For the most tender bites, always slice your prime rib against the grain. Serving thinner slices (about ¼-inch thick) provides the best eating experience and makes your roast go further.
- You can prepare the butter rub up to two days in advance.
