Prime Rib with Dijon Mustard Slather


If you're looking for a recipe that adds a burst of flavor to prime rib, you'll love this Prime Rib Dijon Mustard Slather. It's super easy to make and works well as a meat tenderizer. I let the meat marinade in the refrigerator for a few hours, then let the prime rib roast stand at room temperature for about an hour prior to roasting.

I serve Prime Rib with Dijon Mustard Slather with roasted potatoes or bacon bleu cheese mashed potatoes, along with steamed green beans or roasted corn on the cob. It pairs well with a fresh garden salad and dinner rolls.

Servings: 4 (8 ounce)
Prep Time: 15 minutes
Marinade Time: 2 to 3 hours
Roasting Time: 35 to 45 minutes


2 pound Prime Rib Roast
1/4 cup Dijon Mustard
4 cloves Garlic, mashed
1 Tablespoon fresh ground Black Pepper
1/4 cup Red Wine Vinegar
2 Tablespoons Olive Oil
2 Tablespoons Hot Creamed Horseradish


1. In a small bowl, combine all ingredients, except prime rib roast, and whisk together until well blended.

2. Rub slather over entire roast. Place in a baking dish and store in refrigerator for 1 to 2 hours.

3. Remove roast and let stand for 30 minutes to an hour.

4. Preheat oven to 500 degrees then reduce to 350 degrees when you put the roast in. This will sear the outside and help keep juices locked in.

5. Roast for 18 to 22 minutes per pound for medium rare. Remove from oven and let stand for 30 minutes or until internal temperature reaches 140 degrees before slicing. If you prefer medium, the internal temp should be 150 degrees. For well done, the internal temp should be 170 degrees.

6. Slice meat and transfer to serving dishes. Serve with side dishes, garden salad, and rolls.
