Crock Pot Rump Roast

crockpot rump roast

Rump roast. One of those cuts of meat that makes you scratch your head. I know how you feel and I learned a very valuable lesson early on in cooking. When in doubt on how to cook meat, use a crock pot, they fix everything. Well and you top everything with bacon. In my opinion, a crockpot is the most versatile and valuable tool in the kitchen. I believe in them so much, I spent 2 months making The Ultimate Guide to Crockpots. Enjoy!

Rump Roast in your Crockpot

The name rump roast just makes me laugh. When I started cooking, it actually intimidated me until I learned how to defeat the rump in the kitchen. In the UK, they call the rump roast a Silverside and I like that a lot better. So here are a couple of facts about the rump roast:

  • It comes from the bottom round, the rear leg of a cow
  • It’s a tough piece of meat and tastes best when roasted slowly until tender
  • The three best ways to cook rump roast: A crockpot, braised, or marinated

Did you see that tweet above this? The beef and pork industry changed 350 names of cuts of meat to be more appealing and sell more. Just in case you run to the store to buy a rump roast, it will probably be labeled Leg Sirloin now. You can actually use any tough cut of beef interchangeably with this recipe and get great results.

Crockpot / Slow Cooker

Every one always asks what my favorite crockpot is? I have used at least 5 different brands of slow cookers and crockpots and have finally landed on my favorite. I now own 4 of the same one and they never fail me.

My favorite all around crockpot is the Hamilton Beach Set ‘n’ forget Slow Cooker (6 quart).

I also have favorites of every size and even a Wifi model.

Lately, I have been using One tool to replace 5 different appliances in my house. Click here to see it.

  1. Combine all the spices above together and mix well.
  2. Generously rub this spice mixture all over your rump roast to your taste liking. If you don't like too many spices just lightly coat it.
  3. Line the bottom of your crock pot with your diced onions.
  4. Place your seasoned roast on top.
  5. Pour in your beef stock.
  6. Cover and cook on low for 10 hours.


  1. Made this two days ago and boy is this recipe a keeper. The meat came out so tender and flavorful. Seriously the easiest dish to make and my whole family loved it. It’s actually in my crock pot again today. Can’t get enough.

  2. I was at the store on Jan 4 and found several Rump Roasts in the butcher case. No fancy renaming, despite your tweet.

    Looking forward to cooking the roast in the crock pot over night, and then adding a “pot roast” soup mix I found.

  3. Making this for the family for Christmas – I think I’ll take someone’s suggested advice to start it the night before as I have a 6 1/2 lb roast! Wish me luck!

  4. Made this tonight for my husband and seven year old foster daughter… was absolutely amazing! Seasoned a bit less to meet our taste and added a package on dry onion soup mix on top. It was one of the best tasting, flavorful rump roasts I have ever made. So much better than a recipe I tried that called for mushroom soup. Will use this recipe and again and again.

  5. I put 2 packs of au jous and one pack of ranch dressing powder, half a stick of butter, onion sliced, new potatoes, baby carrots, 1/2 box of chicken broth, 2 garlic cloves. 9 hours, fork tender. Awesome!

    1. Traditionally…chunks of garden fresh sweet carrots are served with pot roast BUT you can serve whatever is your fav!

  6. I have always used chuck roast, but this time i got a rump roast (4lb). I have been slow cooking it for what i normally do (5 hours) but it is sooo tough i can’t believe it. Can someone give me suggestions as to why this happened? A rump roast is the but, right? and i thought it was a better piece of meat that the chuck…?

  7. Hi George

    I made this roast today in the slow cooker and wow is it good. I read all of it’s reviews and tweaked it accordingly. I’ve been making your bacon and garlic roast for a couple of months now and needed to switch up. I stuck with your beef recipes cuz they’re so tasty!

    Thanks so much for this one, it’s really really good. I’m a fan, I own your cookbook!
    Take care, Sandra

  8. Maybe it is the meat where we live, but I find that I need to cook roasts in the slow cooker for 12-14 hours in any of my slow cookers. For those who said that their roast was dry, they may have actually needed longer cook time to break down all of the connective tissue. I usually don’t even bother with putting extra liquid into the slow cooker. As the connective tissue and fat breaks down, the meat is usually covered at least half way in it’s own juices, by the time cooking is done. I find that it is important to let the meat rest in the juices before attempting to slice or shred. Sometimes while I’m taking care of that I will pour the liquid into a cooking pot and place on the stove, to reduce the liquid and concentrate flavor before pouring back over the meat. Or another technique is to shred the meat immediately and return back to the slow cooker with all the little pieces reabsorbing the juices. I prefer the first method. I have also found that with the longer cook times, the flavor in seasonings and any vegetables can wind up cooking right out of the food so that its flavorless. To fix this, I usually start the meat cooking before I go to bed, and then I add seasonings (other than salt and pepper) and any vegetables when I wake up in the morning, just during the last few hours of cooking time. Best of luck. Going to be trying your recipe overnight tonight (adding all the flavoring aspects to the roast in the morning). Although based on the reviews will definitely cut back on the spices a bit! You can always season to your own liking after the dish is done. Best of luck to all… (p.s. we will have this for lunch, and then be trying the honey ham recipe for dinner.)

  9. Delicious…but way too spicy for us. Next time I’ll reduce the spices by 75%. For now, my husband has rinsed the meat under running water, leaving a moist, well-cooked roast that we will enjoy with a tiny bit of the sauce drizzled over it. A 3 lb. roast cooked on high was done in 5 hours.

  10. The meat was tender and pretty moist. I cooked it on high for 4 hours and low for 5 hours. It could have used a little less time but it was still tender and fairly moist. I loved the smell while it was cooking.

  11. As always, this is delicious. The Mr. and I always have plenty of left-overs with this easy recipe.
    Tonight, we are making “tacos” with some of the left-over meat! Guacamole, a little cheese, scrambled eggs, and a “salsa” yummmm
    Thanks George!!

  12. We have made this several times. It is very good. I usually have to use chicken broth as it’s what I have on hand since it’s what is typically brewing.

  13. Tried this one. Pretty good. Maybe it’s my 6qt CrockPot but 10 hours on low was wayyyyyy too long. Meat ended up being a little dry. I even added a little more beef stock. Next time we’ll be doing it for 7 hours.

  14. Love this and ill be making it this weekend! This may be a really stupid question but…. The roast needs to be completely thawed right? Thanks!

  15. WOW thanks for this! Bought my first grass fed rump roast at Whole Foods today and was wondering how long I should cook it since it’s generally a tough cut.
    I luv “spicy” so this will go in the crock tonite before bedtime.

  16. Apologizing for a photo that has my mouth watering and rearranging my menu for tomorrow? Um, NOT NEEDED! Can’t wait to try this–I’ve never used a rub with this combination on a pot roast before. Can’t WAIT to try it!

  17. Sounds great, however, when I chose the “PrintFriendly” option, the ingredients did not print with the picture and process :(

  18. Perhaps a tad spicy but thanks for dinner! (And lunch tomorrow.) The kids certainly didn’t complain. :)

    BTW the photo’s not as bad as you think. Anyway if you want a quick fix, the “sharpen” tool in Photoshop (or Gimp, which is free) would give it more life.

  19. No worries on the photo! :)
    I forgot to tell you that I made this roast over the weekend, and man, is it GOOD! Plus, it made so much that I can bring it for lunch for myself every day *and* share it with the guys at the gym! :D
    I made mine a little bit spicier, as I spilled my whole bottle of paprika all over the kitchen floor…so, I subbed in more chili powder and a dash of cayenne.
