Today’s recipe for Horseradish Crust Ribeye Roast is a meal that will become a family go-to for those times you want to serve something very impressive, but not have to worry about a lot of details in making it.  It uses very few ingredients, most you will have on hand.

What is the difference between a Prime Rib Roast and a Ribeye Roast(or Rib Roast)?

When making this meal when you go to the market you may see all kinds of roasts called many different things.  There are roasts with bones in them and some without.  You will see things marked as a standing rib roast, Prime Rib Roast, Ribeye Roast.  You can use any of these for this recipe.

“Prime” refers to the classification given to the cut of meat by the USDA.  Prime is more expensive because it is a better quality than other classifications. (Other classifications are select and choice.)  You can use a Standing Rib Roast or a Ribeye Roast(Rib Roast).  The terms are used interchangeably these days.  All of these roasts are cut from the rib section, thus the name rib in their name.

A Ribeye Roast is often served without a bone.  The only thing to consider when buying bone-in or boneless when it comes time to cook it is that the cooking time will be a little longer with a bone-in roast.

No matter what you call this meal your guests, (or just your family) will absolutely love it.  It’s always a treat in our house and pretty much shows up on any special occasion or holiday that we are having company over.

How much Prime Ribeye Roast needed per person?

Figure with a bone about one pound per person.  You can also plan by how many bones are in the roast.  One bone yields enough for 2 hearty servings, or 3 as a part of a meal with several sides.

Where to find Horseradish root and how to prepare it?

When making this recipe for Horseradish Crust Prime Rib roast you will need to purchase the horseradish root which is found in the produce section of your local market.  It’s a root vegetable and it looks very nobby and looks somewhat like a fat cream-colored carrot with dirty rough texture.

You will need to peel it and then grate it for this recipe.  You can use a hand grater like I have shown in the picture below, or even put it in your food processor like this one here. 

Since this Horseradish Crust Ribeye Roast is what we use for entertaining often I tend to use a spiralizer like this one here from Sur La Table.  You’ll notice the horseradish comes off in nice spiral ribbons as you grate it. the horseradish in this picture is about 1/3 of what I had originally purchased, imagine a long fat carrot.

Once you have your horseradish ready you will then season your Rib Roast or Ribeye Roast with seasoning salt and mustard and sear it before placing it on a pan to go into the oven.

I place just a few small pieces of horseradish on at the time it goes into the oven.  If you put it on too early it will burn. Here is an example of what the horseradish will look like once it comes out of the oven.  Its crunch, flavorful and not at all hot like you think of horseradish would be.  It makes this recipe not only a beautiful presentation, but the flavor is top-notch!

How long to cook the Horseradish Crust Ribeye Roast?

In general, you can figure cooking the prime rib roast on a higher temp for 20 minutes, then after that about 13-15 minutes per pound.  You will want to have a thermometer on hand to be able to check it.  Pay special attention when sticking the thermometer in to not touch the bone. If you want rare you will cook to 120°-125°, medium-rare 130°-140° Medium 145°-155°.

Other tips for the perfect Prime Rib Roast: 

  • Be sure to pull out the roast about 5° before the final temp that you want to finish at.  It will continue to cook while you rest it.
  • If you have someone who likes their meat a little more done you can give them an end cut because the ends are more done.  If that still isn’t enough and they want it more well done…(gasp, that is blasphemy in our house, but we do have one family member who LOVES it well done) you can place some au jus from the pan juices and pan cook it a little bit more.
  • When you remove the roast it is super important to let it rest for 15 minutes to allow the juices to settle within the meat before cutting.  You can cover it with foil and leave it on the back of the stove where it is warm from the oven and work on the rest of your sides.  (I have a Yorkshire pudding recipe and an Exotic Mushroom bread pudding that will work!)
  • Be generous with the seasoning salt and mustard when you are seasoning the roast.  The crust will get super crispy and you will be happy with how flavorful it is with the big bold beef taste.
  • Looking for a grilled version of Prime Rib? You could opt to make this Grilled Prime Rib with Whiskey Butter instead!

What sides go well with a Horseradish Crust Ribeye Roast:

  1. Dan at Plattertalk has a Cauliflower Gratin recipe in Horseradish sauce for something unique recipe that also has some horseradish in it so it works beautifully.
  2. My recipe for Creamy Scalloped Potatoes you can make ahead and just bake when you put the meat in the oven at the lower temp.
  3. Lemon Blossoms has a Sweet Potato casserole with a topping that you will want to have on everything.
