I never thought a crock pot could handle prime rib. But one cold evening, I gave it a try. The result? Tender, juicy, and full of rich flavor. No oven. No stress. Just slow heat and simple steps. Since then, I’ve made it this way many times. In this guide, I’ll show you how to slow cook prime rib in crock pot without fuss. You’ll learn what to use, how long to cook, and what makes it taste so good. Whether you’re new to cooking or just want an easier way, this method is cozy, simple, and full of flavor.
Why the Crock Pot Works So Well for Prime Rib
The crockpot is perfect for cooking prime rib. It uses slow, steady heat that breaks down fat and makes the meat tender. The juices stay in the pot, so every bite stays moist and full of flavor. You don’t need to check it or flip it.
Compared to oven-roasting, slow cooking is easier. There’s no guesswork. The meat won’t dry out or cook too fast. Pressure cookers work fast but don’t give the same soft texture. The crock pot builds flavor over time.
It’s also great for small meals. One of the best slow cookers for one person can handle a smaller roast with no trouble. That makes it easy to enjoy prime rib, even in a one-person kitchen.

Step-by-Step: How to Slow Cook Prime Rib in Crock Pot
Slow cooking is simple. Just take it one step at a time. No stress. No rush. The crock pot does the work for you.
Step 1: Bring the Roast to Room Temperature
Take the meat out of the fridge. Let it sit for 30 minutes on the counter. This helps it cook more evenly.
Step 2: Season and Sear (Optional)
Pat the roast dry with a paper towel. Rub it with salt, pepper, garlic, and herbs. For extra flavor, sear each side in a hot skillet for 2–3 minutes.
Step 3: Build the Broth Base
Slice one onion and place it in the bottom of the crock pot. Pour in beef broth. Add red wine if you like a deeper taste.
Step 4: Set the Roast and Cook on Low
Place the seasoned meat on top of the onions. The broth should come partway up the side. Cover with the lid. Cook on low for 6 to 7 hours.
Step 5: Rest, Slice, and Serve
Once it’s done, remove the roast and let it rest for 15 minutes. This keeps it juicy. Then slice and serve with warm broth spooned on top.
Expert Tips for Juicy, Flavorful Prime Rib
Great comes down to a few smart steps. Follow these, and you’ll get tender slices every time.
Search for More Flavour
A quick sear adds depth. The crust locks in flavour and brings a rich, roasted taste. Just a few minutes in a hot pan makes all the difference.
Rest Before Slicing
Resting keeps the juices inside. Let the roast sit for at least 15 minutes. Cut too soon, and the meat will lose moisture.
Use the Best Herbs
Garlic, rosemary, and thyme are classic. Fresh herbs brighten the flavor. A light touch is all you need.
Keep Lean Cuts Tender
Roasts with less fat need care. Add extra broth to the pot. Stop cooking once the meat is tender—don’t let it go too long.
Trust a Thermometer
Check the temperature before serving. Medium-rare is 135°F, medium is 145°F. A thermometer removes all guesswork.
Small details like these turn a good roast into a great one.
What to Serve with It: Simple Pairings that Shine
It is rich, so the right sides help balance the meal. A few simple pairings turn it into a feast without extra work.
Mashed potatoes are always a favorite. Creamy and smooth, they soak up the juices perfectly. Roasted vegetables add color and sweetness—carrots, Brussels sprouts, or parsnips work well. A fresh salad on the side keeps the plate light.
Don’t forget the gravy. The broth left in the crock pot is full of flavor. Reduce it on the stove, or whisk in a little cornstarch for a silky sauce. Pour it over the meat and potatoes for pure comfort.
This meal also works on a smaller scale. Even with one of the best slow cookers for one person, you can enjoy prime rib with simple sides. A small roast, a bowl of greens, and a spoon of gravy make a complete, balanced dinner.
Good food doesn’t need to be complicated. These pairings let the prime rib shine while keeping the meal warm and inviting.
What to Do with Leftovers (Don’t Toss It!)
Leftover prime rib is too good to waste. With a few quick ideas, you can turn it into more easy meals.
Wrap the meat tight and store it in the fridge. It stays fresh for up to four days. For longer use, freeze in small packs.
Try it in sandwiches, wraps, or sliders. Chop it for tacos or mix into scrambled eggs. Add it to rice bowls, pasta, or hearty soups.
Save the broth too. Strain and freeze it for sauces or stews. Every drop adds rich flavor.
With smart storage and a little prep, one roast can feed you all week.
Mistakes to Avoid (From My Own Kitchen Fails)
We all make mistakes in the kitchen. I’ve made plenty while learning to slow cook prime rib. Here are the ones to skip.
Skipping the Resting Time
I used to slice the roast too fast. It looked perfect, but the juices ran out. Let it rest for at least 15 minutes. That small pause makes a big difference.
Using Too Much Liquid
More broth doesn’t mean more flavor. Too much can wash out the taste and make the roast soggy. Just enough to come partway up the meat works best.
Overcrowding the Crock Pot
Stuffing in too much meat or adding too many extras blocks the heat. The roast needs space to cook evenly. Keep the pot roomy and simple.
Forgetting to Taste Before Serving
One time, I forgot to check the broth. It needed salt, but I served it anyway. A small taste before plating helps fine-tune the flavor.
Learn from my missteps. These fixes are easy, and they lead to better results every time.
FAQs
Can I skip searing?
Yes, you can. But searing adds flavor and a nice crust. It only takes a few minutes and is worth the effort.
How much liquid do I need?
Not much. Two cups of broth are enough for most roasts. The goal is to keep the meat moist, not to boil it.
Can I add veggies into the same pot?
Yes. Add carrots, potatoes, or onions under or around the roast. Just don’t pack it too full. The meat still needs room to cook evenly.
Final Thoughts
You don’t need to be a pro to make great prime rib. All it takes is time, a little care, and the right approach.
Slow cooking makes this rich cut easy for anyone. Try it once, and you’ll see. It’s simple, stress-free, and full of flavor.
Play around with seasoning. Use more garlic, fresh herbs, or even a splash of wine. Adjust the roast size to fit your needs. The crock pot gives you room to explore.
