This prime rib recipe with an incredibly delicious roasted garlic and rosemary crust featuring Dennis’ Horseradish is refreshingly easy to make. The flavours blend together so well, this is a simple way to turn any dinner into an unforgettable feast.



Preparations are done the day before.

To roast the garlic:

Step One
Heat oven to 350 degrees. Remove all the loose outer ‘paper’ from the bulb. Cut the top off the head.
Step Two
Place each bulb in an aluminum foil square large enough to cover the whole bulb. Drizzle each with a ½ tsp or so of olive oil. Close foil around the bulb. Toss it into the middle of the oven and cook for 30 to 45 minutes. When it is soft to the touch, it is fully roasted.
Step Three
Remove from the oven and let cool. Note the cloves should still be a whitish colour and not too brown.

To prepare the Prime Rib:

Step One
In a food processor, add the horseradish, rosemary, steak seasoning and the peeled, roasted garlic. Slowly add the olive oil and blend it until it forms a nice, smooth paste.
Step Two
Cut the prime rib away from the bone, filet style. Spread a thin layer of the horseradish mixture onto the top of the bone side, then place the trimmed rib meat right on top. Using butcher string, tie the meat back onto the bone.
Step Three
Place the roast in a shallow roaster. Smother the top of the prime rib with the rest of the horseradish mix (this is what’s going to make the spectacular crust.) Cover your roast and refrigerate it for a day, or at least 3 hours.

Cooking Instructions

Step One
Take your prime rib roast out of the fridge an hour before you plan on cooking it.
Step Two
Heat your oven to 500 degrees, place the prime rib in the middle and cook for about 20 minutes.
Step Three
Turn the oven down to 325. Roast until a thermometer reads 125 degrees – it will take about 90 minutes. That’ll give you a nice rare roast. If you like it more well done, cook it to your preference.

Serving your prime rib

Step One
Remove the prime rib from the oven and let it sit for about 20 minutes.
Step Two
Cut the butcher string and remove. Slice roast between the bones and serve on a platter.
Step Three
Spoon some Dennis’ Horseradish into a side dish and serve alongside the roast.
