Ingredients
- 1 boneless prime rib roast (about 6 pounds)
- 2 tsp prepared horseradish
- 2 Tbsp Primal Kitchen Spicy Brown Mustard
- 2 tsp sea salt
- 2 tsp coarsely ground black pepper
- 2 tsp dried thyme
- 2 tsp garlic powder
- 2 stalks celery, cut into 2-inch pieces
- 1 carrot, cut into 2-inch pieces
- 1 small onion, quartered and separated into slices
For the Gravy:
- 2 Tbsp Primal Kitchen Avocado Oil
- 2 Tbsp cassava flour
- 1/4 cup Primal Kitchen Steak Sauce
- 2 cups bone broth
Directions
The day before you want to serve the roast, remove it from the packaging and dry it thoroughly with paper towels. Set the roast on a baking sheet, and leave it in the refrigerator overnight.
Remove the roast from the refrigerator one hour before cooking time, and allow the meat to reach room temperature.
Preheat the oven to 450°F. Rub the roast with horseradish and mustard.
In a bowl, mix together the sea salt, black pepper, thyme, and garlic powder. Sprinkle the spice mix over the roast.
Put the celery, carrot, and onion pieces into the bottom of a roasting pan, then place the roast on top of the veggies.
Roast in the preheated oven for 30 minutes. Reduce the oven temperature to 350°F, and continue roasting the meat until it's browned. Insert a thermometer into the thickest part of the roast. The thermometer should read between 130-135°F for a medium-rare finish.
Once it's ready, remove the roast from the oven, transfer it to a platter, and cover with aluminum foil. Allow the prime rib to rest for 30 minutes before serving.
To make the gravy:
Carefully strain the drippings from roasting pan into a separate bowl.
Heat avocado oil in a deep pan over high heat, then add the cassava flour. Whisk the two ingredients together for approximately one minute.
Gradually add the meat drippings and steak sauce to the mix while whisking. Slowly whisk in bone broth until gravy reaches the desired consistency. Season to taste.
