Ingredients

1 bone in prime rib beef roast, 3 ribs, about 6 pounds
5 garlic cloves, smashed
1/4 cup grated fresh or prepared horseradish
Leaves from 2 fresh rosemary sprigs
Leaves from 4 fresh thyme sprigs
1/2 cup kosher salt
1/4 cup freshly ground black pepper
1/2 cup extra-virgin olive oil
1/2 cup dry white wine
1 tablespoon all-purpose flour
2 cups canned chicken or beef broth

Directions

Preheat the oven to 350 degrees F.

Lay the beef in a large roasting pan with the bone side down. (The ribs act as a natural roasting rack.) In a small bowl mash together the garlic, horseradish, rosemary, thyme, salt, pepper, and olive oil to make a paste. Massage the paste generously over the entire roast. Put the pan in the oven and roast the beef until the internal temperature of the meat registers 125 degrees F on an instant-read thermometer (medium-rare), 1 1/2 to 2 hours. Remove the beef to a carving board and let it rest for 20 minutes before carving.

Pour off some of the pan drippings and place pan on stovetop over medium-high heat.

Add the white wine and bring to a simmer, scraping the bits on the bottom of the pan. Reduce the wine by half. Whisk in the flour, then add the broth and continue to cook, whisking until sauce thickens into a gravy, about 10 minutes.

Serve with Scalloped Potato Gratin and Roasted Red Onions.

Scalloped Potato Gratin:

1 1/2 cups heavy cream

1 sprig fresh thyme

2 garlic cloves, chopped

1/2 teaspoon ground nutmeg

Butter

2 russet potatoes, peeled and cut into 1/8-inch thick slices

Salt and freshly ground black pepper

1/2 cup grated Parmesan, plus more for broiling

Preheat the oven to 375 degrees F.

In a saucepan, heat up the cream with a sprig of thyme, chopped garlic and nutmeg.

While cream is heating up, butter a casserole dish. Place a layer of potato in an overlapping pattern and season with salt and pepper. Remove cream from heat, then pour a little over the potatoes. Top with some grated Parmesan. Make 2 more layers. Bake, uncovered, for 45 minutes. Sprinkle some more Parmesan and broil until cheese browns, about 5 minutes.

Yield: 4 to 6 servings

Roasted Red Onions with Butter, Honey, and Balsamic Vinegar:

6 tablespoons butter

3 tablespoons balsamic vinegar

1/2 cup honey

1/2 bunch fresh thyme

Salt and freshly ground black pepper

4 red onions, halved

Preheat the oven to 350 degrees F.

Combine the butter, vinegar, honey, thyme, salt, and pepper in a small saucepan over medium heat. Bring to a simmer and cook for 1 minute to reduce slightly. Place the onions, cut sides up, in a single layer on a baking pan. Drizzle the butter-vinegar mixture over and roast until soft and slightly caramelized, about 45 minutes.

Yield: 6 servings

WITHOUT A DOUBT "THE BEST PRIME RIB I EVER COOKED"
Rated: 5 stars out of 5

I am from the "older generation" and had been cooking prime rib the same for years. I happened to be watching this episode on... t v and decided to give it a try, actuallly the entire dinner. The prime rib melted in your mouth and the other side dishes were simply delicious. I did everything the recipe called for including the salt and had zero complaints. I have made this several times and it has become my favorite way to serve this marvelous roast. The horseradish and the garlic made it superb. Thank you Tyler. Suzzie from VegasRead more

Perfect Meal!
Rated: 5 stars out of 5

It was excellent. Made a few changes (as per other comments). Cut the salt to 1.5 tablespoons. Cut the pepper to 1.5 tbsp,... and cut the oil to 1/4 cup. It was outstanding, and everyone thought it was excellent. My husband is still raving about it! The gravy turned out very well also, lots of flavour!Read more

easy and fantastic
Rated: 5 stars out of 5

I made this for a family feast this past weekend. Everyone LOVED it and raved about it. I ended up slow roasting this and... used a bone in almost 13 lb of prime rib. (turned the oven 500 and let cook for about 1/2 hr and then turned the over down to 225 for 20 min a lb. and the last 10 min I turned up to 350 ) It was a hit and so easy. Def will make this again! Thanks for the great recipe and keep them coming! JEN D Worcester,MaRead more

He says KOSHER salt, folks
Rated: 5 stars out of 5

I have not made this recipe yet, but all the people complaining about the salt - you do realize he says "Kosher" salt, right?... The crystals are far larger than normal or sea salt, and do not make the food as salty. However, he does say to grind it in a paste with the rest of the ingredients, now I'm a little puzzled myself ...Read more

Yummy
Rated: 5 stars out of 5

This was a great recipe although I agree 1/2 cup of salt is too much. I reduced it to 4 tablespoons as someone else... suggested but still found it salty. I will make this recipe again but with 2 tablespoons of salt.Read more
