Slow Cooker Rump Roast is a classic comfort meal, perfect for Sundays or whenever you’re craving a hearty, hands-off dinner.
A rump roast is a lean and flavorful cut of beef, often referred to as a bottom round roast. This particular cut is ideal for slow cooking, where it can be cooked until tender enough to shred or just enough to be sliced.
This recipe finishes with a rich, savory gravy made from the cooking juices—don’t skip it!
My other favorite recipes that are doused in gravy are Jack Daniels Pot Roast, Slow Cooker Chicken and Gravy, and Slow Cooker Pork Roast.
Magic Ingredients

How to Make Crockpot Rump Roast
Add the ingredients to your slow cooker and let everything simmer together until the roast is tender. Once it’s done, the flavorful cooking liquid can be turned into a simple gravy, making this a satisfying and easy-to-prepare main dish.
Rump Roast Variations
You can easily change up this meal and still get great results. Try these swaps or additions:
- Use any kind of potatoes—just halve or quarter larger ones.
- Add in other veggies like mushrooms, parsnips, celery, green beans, or sweet potatoes.
- For deeper flavor, pour in ½ cup of red wine or beer with the broth.
Serving Tips
Allowing the meat to rest for a few minutes after removing it from the slow cooker helps to retain its juices and makes it easier to slice or shred.
Skip adding the potatoes to the slow cooker and serve over mashed potatoes or steamed rice instead.
Leftover sliced beef is great on sandwich buns.

“My mother used this cut of meat almost every time she cooked a roast beef. It is easy to slice and plates well, as being tender and delicious when really slow cooked. The gravy is the magnificent finishing touch, but I always make mashed potatoes to go with it.

Ingredients
- 3 lb. rump roast, can use 3-4 lbs.
- 1 tsp. kosher salt
- ½ tsp. black pepper
- 1 large onion, sliced
- 2 Tbsp. olive oil
- ½ lb. baby carrots
- 1 lb. baby yellow potatoes

- 1 tsp. dried rosemary
- 5 cups beef stock, (can use beef broth)
- 3 Tbsp. butter
- 3 Tbsp. all-purpose flour
- fresh parsley, for garnish (optional)
Instructions
- Season the rump roast with salt and pepper on all sides. In a large skillet, heat the olive oil over medium-high heat. Sear the rump roast on all sides until it’s browned, about 3-4 minutes per side.
- Place the sliced onion, baby carrots, baby potatoes, garlic, and bay leaves at the bottom of the slow cooker. Add the seared rump roast on top of the vegetables. Sprinkle the thyme and rosemary over the roast. Pour the beef stock around the roast.
- Cover and cook on low for 8 hours or on high for 4-6 hours, until the meat is tender.
- Once the roast is done, remove the roast and vegetables from the slow cooker and transfer them to a serving platter. Cover to keep warm.
- Into a sauce pan, melt the butter over medium heat. Stir in the flour until there are no lumps. Cook the butter mixture for another minute.
- Strain 3 cups of the cooking liquid into the saucepan with the butter mixture and whisk to combine. Continue whisking until the liquid begins to simmer and thickens. Adjust and season with salt and pepper to taste.
- Slice or shred the rump roast and serve with the vegetables, topped with the gravy. Garnish with chopped fresh rosemary if desired. Enjoy!

Delicious, did it with mashed potatoes. I took the garlic cloves from the crock pot and mashed it with the potatoes, yummy!

My mother used this cut of meat almost every time she cooked a roast beef. It is easy to slice and plates well, as being tender and delicious when really slow cooked. The gravy is the magnificent finishing touch, but I always make mashed potatoes to go with it. A little more work than putting little potatoes in with the meat to roast, but so worth it. Thank you for reminding me to get this cut of meat instead of my usual chuck roast.
