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. I’m not great with roasts, but I figured it would be okay if I did it in the crock pot. I read all of the comments about this recipe, and toned down the spices, cooked it for 10 hours, even made gravy for it. I’m sorry to say that I was totally disappointed. The meat was tough, especially the part that was not in the beef broth. It was too spicy and the flavours were not the greatest. I won’t be making this one again…

  2. The reason I do not like digital crock pots is because if you set it and head off to work, and the power goes off for just a second, the crock pot will not turn back on. Living in Florida, if the sky burps, the power is likely to go out for a second.

    I have crock pots of varying sizes to accomplish just about any task, but I will not own a digital crock pot.

    1. Just hack a non digital crackpot using a light timer. Set it to turn on at whatever time you need and/or when you want it to turn off. Your problem is solved!

  3. I’m assuming 10 hours of cooking time is for a -4-6 pound piece of meat. What if I use a smaller piece of meat? Maybe 2-3 lbs? How would you adjust the process?

  4. The texture of the meat turned out amazing, but mine tasted so strong with black pepper. Did I possibly add the wrong amount (too much!), or does this rump roast intentionally have a strong taste of pepper? Had to read online to figure out how to tone down pepper (fyi add lemon, and sugar if needed to balance acid). Just curious…maybe I accidentally added too much pepper??(my 3.5 yr old was helping me’s possible?)

    1. I used black peppercorns and crushed them myself, and I also thought the pepper was strong (and I love pepper). I’d cut the black pepper by 1/3 to 1/2. I also like the addition of a few tablespoons of apple cider vinegar, as it helped mellow out the pepper flavor. I also added a bunch of carrots and red potatoes. Great recipe, but not kid friendly at the full pepper strength!

  5. I add 4 teas. of apple cider vinegar to some beef broth and mix it together and poor it over the rump roast and it helps it break down better and I usually crick mine 10 hours. Scrumptious. Melt in your mouth tender. I also add carrots, potatoes and chopped onion and salt and pepper. Perfect every time.

  6. I usually cook a Chuck Roast but store was out , my boys like the gristle , so I got a Rump Roast not knowing how to cook it. Thanks for the help , it was delicious

  7. I make this often, any cut of meat that’s on sale works great! Not on the Paleo diet, just loved George’s preface to the recipe. Had me cracking up! Had to try it! I use whatever broth I may have, even used beer once, it was fabulous! Enjoy everyone! This is a winner!

  8. Question: I looked at Wild Oats and Swanson Organic beef broth today, both had cane sugar and one had soy…I know you aren’t suppose to have sugar on Paleo and I’m allergic to soy, do you know of a beef broth without? I just put your recipe in the crockpot but added water instead of beef broth, hope it turns out okay!

  9. 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.

  10. 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.

  11. 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!

  12. 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.

  13. 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!

  14. 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…?
