I enjoy a good pot roast, but was tired of the same old thing. So, I began experimenting. Cooking the beef in horseradish sauce gives it a tangy flavor. Even my young children love this slow-cooker pot roast with its tender veggies and gravy. —Mimi Walker, Palmyra, Pennsylvania


  • 1 beef rump roast or bottom round roast (3 to 3-1/2 pounds)
  • 2 tablespoons canola oil
  • 4 medium carrots, halved lengthwise and cut into 2-inch pieces

Slow-Cooker Rump Roast Tips

How do you tenderize a rump roast?

Rump roast is a lean and economical cut that is tasty, yet tough. This cut typically takes a longer time to become tender. The best way to cook it is to braise it in the oven, or to use a slow cooker. Once cooked, slice the roast thinly against the grain to maximize tenderness.

How do you keep meat from drying out in a slow cooker?

There are several factors to keeping slow-cooked meat moist. Make sure your lid fits properly, and that you don’t remove it during cooking. Small cuts of meats dry out during cooking much faster than larger pieces. Also, use the right size slow cooker. Small amounts of food in a large slow cooker will cook faster, causing them to dry out before the end of the cooking time.

What are some variations of rump roast?

Similar cuts of beef that could be used in place of bottom round are sirloin tip roast and eye of round roast. You could also consider chuck roast, which is a great cut for the slow cooker. There is a lot of tangy flavor from the horseradish sauce and vinegar, but you could cut back on those and replace the water with apple juice for a sweeter flavor. Celery salt is a classic seasoning for pot roast recipes, but Italian herbs like basil, oregano and thyme in place of the celery salt would create a pleasant and homey dish as well.
