Prime Rib is a delicious cut of meat. The easy beef recipe can be made in the slow cooker for an impressive weeknight meal or a holiday meal.

You may have tried our Easy Prime Rib Recipe in the oven or this Texas Roadhouse Prime Rib Recipe. Using the crock pot saves oven space and makes the steak flavorful and juicy.

Why We Love This Recipe

Crock pot prime rib is the perfect meal to prepare when you want to make a nice Christmas dinner or for any occasion. Making it in the slow cooker allows you to toss everything in and let the crock pot do all the work.

The prime rib turns out super juicy and bursting with flavor.

How to Choose the Right Prime Rib

When we make prime rib, or standing rib roast, in the oven we always recommend using the bone-in option. But for the slow cooker, we make the boneless option. We like to keep the untrimmed fat cap on the prime rib for the flavor and how juicy it cooks.

For best results, ask your butcher for the prime-grade option for best results.

Variations Ideas

  • Veggies – A delicious variation to this recipe is to cook the prime rib with vegetables. You can easily add in carrots, potatoes, and celery.

Step by Step Instructions

Rubbing oil over the prime rib

Step 1 – Pat the prime rib dry using paper towels. Rub the entire surface of the meat with olive oil. In a small bowl, combine the coarse sea salt and pepper, garlic powder, onion powder, dried rosemary, and dried thyme. Rub this seasoning mixture all over the prime rib.

Placing the onions quarters and garlic in the slow cooker

Step 2 – Place the quartered onions and minced garlic at the bottom of the Crock Pot.

Placing the seasoned prime rib in the slow cooker

Step 3 – Carefully place the seasoned prime rib on top of the onions and garlic in the Crock Pot.

Pouring beef broth into the slow cooker

Step 4 – Pour the beef broth and red wine around the meat in the Crock Pot. Ensuring not to pour it over the meat so the seasonings remain intact.

  • Step 5 – Cover the Crock Pot and cook on a low setting for 6 hours, or until the meat reaches your desired level of doneness. For a medium-rare finish, the internal temperature should be approximately 130 to 135 degrees Fahrenheit.
  • Step 6 – Once cooked, remove the prime rib from the Crock Pot and let it rest for about 20 minutes to 30 minutes before slicing. This resting period allows the juices to redistribute throughout the meat.
  • Step 7 – Slice the prime rib on a cutting board and serve, using the juices from the Crock Pot as a sauce if desired.

Recipe Tips

  • Monitoring Cooking Time – Cooking times may vary depending on the size of the roast and your crockpot. For the perfect prime rib in a slow cooker, use a meat thermometer to check for doneness.
  • Importance of Resting – Allow the cooked prime rib to rest before slicing to ensure juiciness and makes it super tender.
  • Sauce Options – For a thicker sauce, simmer the Crock Pot juices with a cornstarch slurry on high heat.
