Prime Rib Roast with Miso Jus
Prime Rib seems so intimidating to cook, but in all honesty, it’s easier than roasting a turkey. There’s no brining, stuffing a cavity, flipping halfway or injecting with marinade. Cooking the most tender Prime Rib only uses one cooking rule – slow ‘n low. All you need is time.

This is by far the most simple way to cook a Prime Rib Roast – my trick is to start with a savory-sweet-umami-rich ingredient, Miso Paste. Rubbing the Prime Rib Roast with miso, salt and pepper will season the roast nicely. If you’re concerned that the Prime Rib Roast will taste like miso soup – let me give you a guarantee that it certainly won’t. When miso is combined with meat and heat, the flavor profile helps deepen the flavor of the meat itself, much better than just plain salt. It’s like the difference between sprinkling salt on your bread vs. spreading a rich butter.
In my recipe, you can either use low-sodium miso paste (my favorite is shiro miso, which is white miso) or Miso & Easy, a super easy to use miso product, from the makers of one of Japan’s #1 brand of miso, Marukome. I’ve developed quite a few recipes for them over the past year – come take a look.
Prime Rib Roast with Miso Au Jus Recipe
Prep Time:10 minutes
Cook Time:20 minutes per pound
salt and freshly ground black pepper
1/3 cup miso paste (or 1/2 cup Miso & Easy), divided
5 large carrots, halved
8 stalks celery, halved
2 onions, halved
1 cup red wine
2 cups good quality beef stock
Heat the oven to 250F. Season the rib roast on all sides with salt and pepper. Rub just 2-3 tablespoons of the miso (keep the rest of the miso for the Au Jus) on all sides of the rib roast. Place rib roast in a large roasting pan. Scatter the vegetables all around the roast.
Roast for 17-20 minutes PER POUND or until temperature of the middle of the roast is 130F (medium-rare to medium). Turn the broiler to high and let the roast brown a bit on the outside, for about 5 minutes. Transfer roast to cutting board, carefully untie the bones from roast. Cover loosely with tin foil. Rest for 20 minutes.
While roast is resting, make the Miso Jus. Keep the vegetables in the roasting pan but discard all but 1 teaspoon of the fat. Place the roasting pan 2 burners set on high heat.
Pour in the red wine and cook until wine is reduced by half. Use a wooden spoon to scrape up the bits. Whisk in the beef broth and 2 tablespoons of miso paste (or 3 tablespoons Miso & Easy). Turn heat to medium-low and simmer for 15 minutes. Add any juices accumulated from the rib roast on the cutting board. Turn off heat.
Strain the jus with mesh strainer, pressing down with wooden spoon to extract out all the juice from the vegetables. Carve the roast, serve with the jus.
