What is a Rump Roast?
A rump roast is a specific cut of beef that makes for a perfect roast when cooked low and slow.
It comes from the cow’s hindquarters, specifically the top part of the back end (near the hip). It’s a lean cut with relatively little fat and marbling, which means it can be a bit tougher if not cooked properly. However, with low, slow cooking methods—like roasting or using a slow cooker—the meat breaks down to become tender and flavorful.
Rump roast is pretty often affordable which makes it a popular choice for family meals. Its rich flavor makes it perfect for pot roasts, stews, and other hearty dishes that benefit from long cooking times and seasoning.

How to Make Tender Slow Cooker Rump Roast

Ingredients:
- 2.5 lbs rump roast
- 1.5 lbs yellow baby potatoes

- 1 onion
- 1 sprig rosemary
- 3-4 sprigs thyme
- 1 tsp salt, or to taste

Instructions:
This recipe couldn’t be easier! It is perfect for chilly winter days, makes a whole meal, and takes mere minutes to prep. First place the rump roast in the slow cooker and season with salt and pepper.

Place all the baby carrots around the roast. (You can also use regular carrots sliced in half and then quartered.) Peel and quarter the onion. Use your fingers to break up the onion layers and sprinkle around the roast.
Scrub the baby potatoes and place atop everything else. They absorb the flavor and juices they are cooker in very easily so it’s best to place them on top so they don’t get too saturated and mushy.

Add all remaining ingredients in the slow cooker over and around the meat.

Cook on low for 7-8 hours or on high for 4-5 hours. Once cooked, cut the beef and serve warm.
