Eleven ingredients and about two and a half hours, including the rest.
The roast comes out of the fridge before it goes in the oven, gets a herb-butter rub, and is carved over rice rather than served with potatoes or a jug of jus.
Why This Recipe Works
- Letting the roast stand for forty-five minutes takes the deep chill off, so it cooks more evenly.
- Fifteen minutes at 450F sets the dark outside before the temperature drops.
- Finishing at 325F brings the middle up slowly, which is what keeps it rosy.
- Softened butter carries the garlic and herbs and stays where it is rubbed.
- A long rest lets the juices settle so the slices stay neat rather than flooding the rice.
The Roast Is Judged Once, With a Thermometer
A four-to-five-pound roast gives no reliable outside cue: the crust is dark within fifteen minutes and stays that way for another hour and a half. So there is one gate in this recipe, and it is a safety one - WHOLE-CUT BEEF MUST REACH AT LEAST 145°F AND REST AT LEAST 3 MINUTES.
- 45 minutes out of the fridge, oven at 450°F1 BONELESS PRIME RIB ROAST, 4 TO 5 LB, TAKEN OUT ABOUT 45 MINUTES BEFORE ROASTING. A roast straight from the refrigerator cooks unevenly - the outside overshoots while the middle lags.
- Seasoned, then the GARLIC-HERB BUTTER2 tsp SALT and 1 tsp PEPPER, then 4 tbsp SOFTENED BUTTER mixed with 4 FINELY GRATED GARLIC CLOVES, 1 tbsp ROSEMARY, 1 tbsp THYME and 1 tbsp PARSLEY RUBBED OVER THE ROAST. Softened, not melted, so it clings.
- 15 minutes at 450°F, then 325°FROASTED 15 MINUTES AT 450°F, THEN REDUCED TO 325°F. The high start is for the dark exterior; the low finish is what carries the centre up gently.
Check before you continue
At least 145°F, then a rest of at least 3 minutes — An instant-read thermometer in the centre of the roast
The oven time is open-ended on purpose: CONTINUE ROASTING UNTIL THE CENTER REACHES AT LEAST 145°F, because a four-pound roast and a five-pound roast do not take the same time. RESTED AT LEAST 3 MINUTES, PREFERABLY 15 TO 20 MINUTES FOR CLEANER SLICING.
- The RICE, cooked during the rest1 1/2 cups LONG-GRAIN WHITE RICE cooked with 2 1/4 cups WATER UNTIL FLUFFY, with 1 tbsp OLIVE OIL and the REMAINING PARSLEY FOLDED IN. The rest is exactly long enough for it. If it will not be served at once, cool it promptly.
- Carved over the riceThe rice SPREAD ACROSS A PLATTER, the roast SLICED and THE ROSY SLICES ARRANGED OVER THE RICE, with ANY GARLIC-BUTTER PAN JUICES SPOONED LIGHTLY OVER THE BEEF. The rice bed is what defines the dish, and there is NO JUS, POTATOES OR HORSERADISH.
Ingredient Notes
- Boneless prime rib roast
- Four to five pounds. Boneless is what makes the even slices in the photograph straightforward.
- Softened butter with garlic, rosemary and thyme
- Four tablespoons with four grated cloves and a tablespoon each of the herbs, rubbed over the outside.
- Long-grain white rice
- A cup and a half cooked in two and a quarter cups of water. The rice bed is named in the title and is not a side dish.
- Parsley, divided
- Two tablespoons: one into the butter rub, one folded through the finished rice.
How to Make It
Roast out of the fridge 45 minutes, oven to 450°F
Take the prime rib out of the refrigerator about 45 minutes before roasting. Heat the oven to 450°F.
Seasoned, then rubbed with garlic-herb butter
Season the roast with the salt and pepper. Mix the softened butter with the garlic, rosemary, thyme and 1 tablespoon of the parsley and rub it over the roast.
Fifteen minutes hot, then 325°F until 145°F inside
Roast 15 minutes at 450°F, then reduce the oven to 325°F and continue roasting until the centre reaches at least 145°F.
Rested at least 3 minutes, better 15 to 20
Rest the roast at least 3 minutes, preferably 15 to 20 minutes for cleaner slicing.
Rice cooked during the rest, oil and parsley folded in
While the beef rests, cook the white rice with the water until fluffy and fold in the olive oil and the remaining parsley.
Rice spread on a platter, slices arranged, juices spooned over
Spread the parsley rice across a platter, slice the prime rib and arrange the rosy slices over the rice. Spoon any garlic-butter pan juices lightly over the beef.
Success Tips
- Put the thermometer into the thickest part of the roast, away from any fat seam.
- Start the rice when the roast comes out, so both are ready at the same moment.
- Carve across the roast in even slices so each one sits flat on the rice.
Serving Ideas
Six servings from one platter: parsley-flecked white rice spread across it, rosy slices of garlic-butter prime rib laid over the top, and the pan juices spooned lightly over the beef.
Frequently Asked Questions
How do I keep the centre pink and still safe?
Roast to at least 145°F in the centre and rest it. A thick roast holds a rosy interior at that temperature, and the rest lets it settle.
Is the rice really part of the recipe?
Yes. The rice bed is named in the title and is what the roast is carved over, rather than potatoes or a separate side.
What about jus or horseradish?
Neither is part of this version. The only sauce is the garlic-butter pan juices spooned lightly over the slices.
