This crock pot rump roast is made of simple beef, carrots, and potatoes cooked low and slow for hours until the meat is fall-apart tender. Everything comes out so flavorful! Even better, this recipe requires only 20 minutes of prep time.

Tender Crock Pot Rump Roast

Imagine this. At 10 AM, you arrange a bunch of simple, delicious ingredients into a slow cooker before going about the rest of your day. The rich, earthy smell of beef and potatoes grows strong. As the hours pass, they waft through the house. 6 o’clock rolls around, and everyone is home from work or school, looking around for the source of that magical smell.

You sit down at the table to hearty servings of carrots and potatoes piled with tender, melt-in-your-mouth portions of beef loaded with simple, heartwarming flavors the whole family will love. Everyone falls silent as they devour the delicious meal that only took you 20 minutes to prep. Success! 🙌

Why You’ll Love This Recipe

This heartwarming meal is sure to make it to your favorites list. Here are some of the reasons I love it so much.

• Fall apart tender. Cooking a naturally tough cut of beef, like rump roast, for a long time at a low temperature transforms it into a deliciously tender entree.
• Set it and forget it. I love that all you have to do is sear the meat, place it in the crock pot with a few other ingredients, and press some buttons. 8 hours later, you have a heartwarming meal waiting for you. It’s the perfect recipe for a busy day.
• All-in-one meal. Although you can serve this rump roast with a side dish or two (see the section below titled “What Goes With Rump Roast?” for inspiration), you do not need to. The meat, carrots, and potatoes deliver a well-rounded meal on their own.
• The gravy. You can opt out of making the gravy if you are pinched for time, but it does pull the whole thing together. Smooth and rich, it seeps into every cranny of meat and veggies. It will have you craving a second bite before you swallow your first.

What You’ll Need

Meat, potatoes, and some seasoning. That’s pretty much all it takes. Here’s a list of what you will need to make a crock pot rump roast. Don’t forget to scroll to the recipe card below for measurements.

For the rump roast

• Rump roast: You could also use chuck roast or top sirloin instead.
• Yellow onion
• Carrots
• Baby potatoes: I prefer baby potatoes, but any waxy potato will do. If you use waxy potatoes, cut them into 1-inch chunks.
• Garlic
• Dried oregano
• Bay leaves
• Avocado oil
• Beef stock: You can use water instead; just make sure to season a bit more heavily.

For the gravy

• Salted butter
• All-purpose flour

What is a Rump Roast?

Rump roast is a large cut of beef taken from the cow’s top portion of the backside. It is relatively low in fat and has a rich, beefy flavor. Due to the leanness of the cut, rump roast is best enjoyed after being cooked at a low temperature for many hours. The process breaks down the meat, making it tender.

How to Cook a Rump Roast in the Crock Pot

Here’s a quick rundown of how to make rump roast in a crock pot. Be sure to scroll to the recipe card below for more detailed instructions.

For the rump roast

• Season the rump roast with sea salt and ground black pepper and let sit for 15 minutes.
• Add the veggies to the crock pot along with the garlic, oregano, and bay leaves.

• Brown the beef. Heat the olive oil in a heavy-bottomed pan over medium-high heat. Brown the beef for 2 minutes on all sides.

• Cook. Add the beef to the slow cooker, add the beef stock, cover the slow cooker, and cook on low heat for 8 hours. Flip the roast halfway through cooking.
• Serve. Shred the beef and serve it over the cooked veggies with gravy.

For the gravy

• Melt the butter in a saucepan over medium heat.
• Add the flour and whisk continuously for 2 minutes.
• Add the cooking liquid (about 3 cups) gradually, whisking continuously until smooth.
• Simmer for 3 to 4 minutes or until thickened and ladle over individual portions of crock pot rump roast.

Tips for Success

Here are a few simple tips and tricks that will help you achieve a tender, flavorful rump roast. Happy cooking!

• Season liberally. Don’t be shy with the salt and pepper. No one wants a bland rump roast.
• Sear. It makes a difference to take an extra few minutes to sear the rump roast before adding it to the slow cooker. The end product will have a much more full-bodied flavor and will be more visually appealing.
• Get the liquid right. Your roast does not need to be submerged entirely here, but it should be at least 3/4 of the way submerged. Feel free to add a bit more liquid than prescribed in the recipe to make this possible.
• Flip halfway through. If you are around the house while the roast is cooking, I highly suggest that you flip it halfway through the cooking time. Rump roast is a tough piece of meat, and exposing both sides of the roast directly to the cooking liquid will help it break down more.
• Give it more time. If the rump roast is not falling apart tender by the time 8 hours of cook time have passed, go ahead and give it another hour in the slow cooker.

What Goes With Rump Roast?

One of the best things about this recipe is that it delivers a hearty dose of protein, carbs, veggies, and fats on its own. So you don’t really need any side dishes. That being said, you can take this rump roast to the next level by serving it alongside some dinner rolls, a salad, or more veggies. Here are some ideas:

• Dinner rolls. Try these Orange Glazed Sweet Dinner Rolls or my Macedonian Dinner Rolls with Feta Cheese.
• Salad. Lighten things up with my Green Goddess Salad, this Crunchy Kale Quinoa Salad, or my Heirloom Tomato Salad.
• Mashed potatoes. There are already potatoes in this recipe but feel free to leave them out and serve the tender beef with my Instant Pot Mashed Cauliflower with Garlic and Chives or these Garlic Rosemary Mashed Potatoes instead.
• Horseradish sauce. Regardless of what side/s you choose to serve with your rump roast crock pot, I implore you to try spooning a bit of creamy horseradish sauce on top.

How to Store and Reheat Leftovers

• Allow the dish to cool completely before sealing it in an airtight container and storing it in the refrigerator for up to 4 days.
• Reheat on the stovetop over medium-low heat or in the oven, covered, at 325˚F for 15-20 minutes or until heated through. It can be helpful to add some beef broth to the pan or baking dish to keep things from drying out.

Can I Freeze Extras?

You can, in part. I do not recommend freezing the veggies as they will not reheat well. The beef will freeze and reheat beautifully.

• To freeze: Let it cool before separating the beef from the veggies. Shred the meat and transfer it to an airtight container, and store in the freezer for up to 3 months.
• Thaw in the refrigerator overnight. To reheat, do so on the stovetop over medium-low heat or in the oven, covered, at 325˚F for about 30 minutes or until heated through.

Instructions 

For the rump roast

• Season the rump roast with sea salt and ground black pepper and let sit until it comes to room temperature (about 15 minutes).
• In the meantime, add the chopped yellow onions, carrots, baby potatoes, garlic, oregano, and bay leaves to the bowl of a slow cooker. Set aside.
• Heat the avocado oil in a heavy-bottomed pan over medium-high heat.
• Place the seasoned rump roast in the pan and let sear for 2 minutes before flipping and searing for 2 minutes on the other side.
• Transfer the seared rump roast to the slow cooker; pour in the beef stock. The liquid should cover about 3/4 of the rump roast. If needed, add more broth.
• Close the slow cooker and cook on low heat for 8 hours, flipping the roast halfway through.
• When cooking time is up, remove the beef from the slow cooker and transfer it to a cutting board. Shred the rump roast using two forks or meat shredders – it should be fall-apart tender. If it's not pulling easily, place it back in the slow cooker and continue to cook for 30 more minutes and up to one hour.

For the gravy

• Melt the butter in a saucepan over medium heat.
• Add the flour and whisk continuously for 2 minutes (do NOT allow the mixture to brown)
• Slowly add 3 cups of the cooking liquid from the slow cooker, whisking continuously until smooth.
• Allow the gravy to simmer for 3 to 4 minutes or until thickened to your desired consistency, stirring occasionally.
• Serve the shredded rump roast over the carrots and potatoes and top with the gravy.

Equipment

• Slow Cooker
• Chef Knife
• Cutting Board
• Meat Shredders/Claws

Notes

• Rump Roast: A rump roast is a cut of beef from the top of the back end of a cow. A lot of people use chuck roast and rump roast interchangeably. While both cuts of meat come from parts of a cow, their similarities end there because chuck roast is a different cut; it comes from the cow’s shoulder portion. But on that note, you can also use a chuck roast to make this recipe.
• Potatoes: I almost always use gold/yellow baby potatoes for roast dinners, but you can use any thin-skinned waxy potato you have on hand. If they are bigger potatoes, cut them to 1-inch chunks before cooking. 
• Season the rump roast with salt and pepper, and when it’s done cooking, give it a taste and see if it needs more salt. 
• Searing the beef before putting it in the slow cooker is not a must, but it does make a difference in taste and appearance. 
• Add enough liquid (beef stock) to the slow cooker to cover about 3/4 of the rump roast. 
• If at all possible, flip the roast halfway through cooking. It’s okay if you don’t. 
• If the beef does not shred easily, put it back in the slow cooker and continue to cook it for 30 minutes to one hour.
