Instructions
Prime Rib Rub
- Place all ingredients in a small bowl and whisk until fully incorporated.
Horseradish Mustard
- Place all ingredients in a small bowl and whisk until well-incorporated.
Herb Breadcrumbs
- Place all ingredients in a small bowl and whisk until fully incorporated.
Prime Rib Roast
- Place prime rib roast in refrigerator for 48 hours until completely thawed.
- Remove prime rib roast from refrigerator, pat dry on all sides with paper towels, rub down with 2 tablespoons grapeseed oil, and season with prime rib rub; let come to room temperature for about 30 minutes.
- Preheat oven to 250 degrees Fahrenheit.
- Add 1/2 cup grapeseed oil to cast-iron pan and bring to medium-high heat.
- In the cast-iron pan, sear the roast on all sides until golden brown all over, about 2-3 minutes each side.
- Place seared prime rib roast, fat-cap-up on the wire rack-lined sheet pan and place in the preheated oven.
- Cook prime rib roast for about 30 minutes, remove from the oven, brush horseradish mustard on the fat cap and add breadcrumbs on top of mustard, then return to oven.
- Continue cooking prime rib roast until internal temperature is 10 degrees below desired cooking doneness, about 2 hours for medium-rare doneness. Refer to the Omaha Steaks cooking chart for a different desired cooking doneness.
- Once targeted temperature is reached, broil prime rib roast until the herb breadcrumb crust is lightly golden brown. Watch closely and be careful not to burn the herb breadcrumb crust during this step.
- Allow the prime rib roast to rest for about 20 to 25 minutes.
- Then slice and serve with roasted cauliflower.
Roasted Garlicky Cauliflower
- Preheat oven to 400 degrees Fahrenheit.
- In a small bowl, mix kosher salt, black pepper, and paprika together.
- Toss the cauliflower, olive oil, and spices together.
- Line a sheet pan with aluminum foil and add cauliflower on there.
- Roast cauliflower for 10 minutes, flip with spatula, and roast for an additional 10 minutes until browned and tender.
