How to Make Dijon-Rubbed Prime Rib With Cheddar Crumb Mashed Potatoes
Making a delicious prime rib is easier than ever with Omaha Steaks Boneless Heart of Prime Roast. Expertly prepared by master butchers and trimmed to perfection, this roast boasts beautiful marbling that delivers rich flavor, incredible tenderness, and juicy results every time. The velvety smooth Omaha Steaks Roasted Garlic Mashed Potatoes make for the perfect side.
1. “Spice The Halls” With Dijon Joy
The Dijon rub adds the right balance of tangy and aromatic depth, helping the crust lock in flavor while enhancing the richness of the roast. Combine whole-grain mustard, Worcestershire sauce, and olive oil in a small mixing bowl, whisk until well mixed and set aside.
2. Topping Tidings Begin Here
A crispy crumb coating adds the perfect contrast to creamy mashed potatoes, bringing texture, richness, and a golden, festive finish to every bite. Add finely blended buttery round crackers, unsalted butter, and black pepper to a medium bowl and mix until everything is well combined. Set aside until the mashed potatoes are ready.
3. The Roast of the Season
To cook the perfect prime rib, start by thawing your Omaha Steaks Boneless Heart of Prime Rib Roast in the refrigerator for 48 hours. In a small bowl, combine the kosher salt and cumin. Once thawed, pat dry with paper towels and season generously with dry seasoning mix. Let the roast sit at room temperature for about one hour.
While the prime rib comes to room temperature, preheat your oven to 250 degrees Fahrenheit. In a large cast-iron pan, heat grapeseed oil over medium-high. Sear all sides of the roast for about two minutes per side until golden brown.
Transfer the seared roast to a large wire rack-lined sheet pan. Brush the Dijon rub all over, and place in the oven. Cook roast until 10 degrees below the desired doneness via a meat thermometer. For medium-rare doneness, cook for about one hour and 15 minutes to one hour and 30 minutes. Refer to our helpful Omaha Steaks Roast Cooking Chart for different doneness temperatures.
Once done, remove the roast from the oven and increase the temperature to 400 degrees Fahrenheit for the potatoes. Let the roast rest for 15 to 20 minutes before slicing.
4. Say Cheese (and Pass the Potatoes)
Cheesy mashed potatoes topped with a crispy crumb strike the perfect balance of creamy comfort and golden crunch, making them an irresistible side dish that complements this holiday roast.
There’s no need to thaw your Omaha Steaks Garlic Mashed Potatoes – just remove the plastic wrap and microwave on high for three to four minutes. Stir, then microwave for an additional minute.
Transfer the potatoes to a medium cast-iron pan and stir in the cheddar cheese until fully combined. Sprinkle the crispy crumb evenly over the top. Bake in the oven for 15 minutes until the top is golden brown and bubbly. Serve hot with the prime rib.
