Prime rib roast, also referred to as "standing rib roast," is a tender cut of beef from the rib section, according to the Chicago Steak Company.


Prime rib roast is delicious and tender because it has a lot of fat marbling (which also makes it higher in saturated fat). You'll want to cook it in liquid or its own juices to prevent it from drying out.

That's why a slow cooker, like the Crock-Pot, is a wonderful way to cook a prime rib roast and vegetables — it creates a tender, juicy result with little fuss and no hot oven.

Slow Cooker Prime Rib Recipe

Things You'll Need

  • 4 lbs. prime rib roast or standing rib roast, bone-in

  • 1 cup red wine

  • 1 cup beef stock

  • 1 bay leaf

  • 3 cloves garlic, peeled and smashed

  • 3 celery stalks, chopped

  • 1 large red onion, chopped

  • 3 large carrots, peeled and chopped

  • 1 lb. fingerling potatoes, scrubbed clean, skins on

  • 1 tsp. dried rosemary

  • 1 tsp. dried sage

  • 1 tsp. salt

  • 1 tsp. ground black pepper

  • 1 tsp. garlic powder

  • Large serving platter

  • Gravy boat (optional)

  • Slow cooker

  • Food thermometer

Step 1: Combine Liquid Ingredients

Place red wine, beef stock and a bay leaf into a slow cooker. Stir to combine.

Step 2: Add the Veggies

Arrange garlic, celery, onion, carrots and fingerling potatoes in the broth mixture on the bottom of the slow cooker in an even layer.

Step 3: Season Your Meat

Sprinkle rosemary, sage, salt, pepper and garlic powder all over a prime rib roast. Pat the spices into the meat.


Step 4: Place Meat in the Pot

Place the standing rib roast with the bone side down and the fat side up on top of the vegetables. Turn the slow cooker on low heat and cover with the lid.

Step 5: Cook It

Cook for 6 hours on low, until the roast reaches a safe internal temperature of 145 degrees Fahrenheit, per the USDA. Use a food thermometer to check the temp.

Note that cooking rib roast in a Crock-Pot until well-done or using a high heat setting is not recommended because it'll dry out the meat and make it tough instead of tender.


Step 6: Let It Rest

Remove the roast and place it on a serving platter. Allow the meat to rest for 10 minutes so the juices settle in before cutting and serving.

Step 7: Serve

Arrange the vegetables on the serving platter around the roast. Serve the cooking liquid in a gravy boat, if desired.


You can trim the fat off the rib roast after cooking it to reduce your intake of saturated fat.

Side Dish Ideas

While your Crock-Pot prime rib is already made with a bunch of veggies, you can serve the protein with extra side dishes — such as grains and other vegetables — for a complete meal. Try a few of these side dish ideas:
