Helpful Tips

• For extra flavor, you can sear the roast in a hot skillet for 2–3 minutes per side before placing it in the slow cooker. This step is optional and is not required for a delicious roast.
• Let the roast rest for about 10 minutes before slicing to help keep the juices inside the meat.

Ingredient Notes

Rump Roast
Rump roast is an affordable cut of beef that’s perfect for making a tender slow cooker pot roast. As it cooks low and slow, it becomes flavorful, juicy, and easy to slice or shred.

Yellow Baby Potatoes
Yellow baby potatoes hold their shape well during the long cooking time while becoming soft and buttery.

Baby Carrots
Baby carrots add natural sweetness and cook until perfectly tender alongside the roast.

Yellow Onion
A medium yellow onion adds rich flavor to the broth while becoming soft and flavorful as it cooks.

Fresh Rosemary and Thyme
Fresh herbs give the roast a classic savory flavor that pairs perfectly with beef and vegetables.

Beef Broth
Beef broth helps keep the roast moist while creating a flavorful cooking liquid that’s delicious spooned over the meat and vegetables.

Directions:

Step 1

Place the rump roast into the slow cooker.

Season both sides with the salt and black pepper.

Step 2

Add the baby carrots and quartered onion around the roast.

Step 3

Add the baby potatoes to the slow cooker.

Pour the beef broth over the roast and vegetables.

Top with the fresh rosemary and thyme.

Cover with the lid.

Cook on Low for 7 to 8 hours or High for 4 to 5 hours, until the roast is fork tender.

Slice or shred the beef, then serve with the potatoes, carrots, onions, and cooking broth.

Recipe Notes

• Trim any large pieces of excess fat from the roast before cooking.
• Try to keep the potatoes in larger pieces so they don’t become overly soft.
• Taste the broth before serving and adjust the salt and pepper if needed.
• Leftovers make excellent sandwiches, wraps, or beef and vegetable soup the next day.
• If your slow cooker tends to cook hot, begin checking the roast about 30 minutes before the minimum cooking time.

Frequently Asked Questions

What is the best cut of beef for slow cooker rump roast?

Rump roast is an excellent choice because it becomes tender and flavorful when cooked low and slow. Chuck roast is another popular option if you prefer a roast with more marbling.

Should I brown the roast before putting it in the slow cooker?

No. This recipe is designed to be a simple dump-and-go meal, so browning isn’t necessary. However, if you have a few extra minutes, searing the roast can add additional flavor.

Why is my rump roast tough?

If your roast is still tough, it likely needs more cooking time. Rump roast becomes tender as the connective tissue slowly breaks down during the long cooking process.

Can I use frozen carrots?

Yes. Frozen carrots work well in this recipe and can be added directly to the slow cooker without thawing.

Can I substitute dried herbs for fresh herbs?

Yes. If you don’t have fresh rosemary or thyme, use about 1 teaspoon of dried rosemary and 1 teaspoon of dried thyme instead.

Can I add more vegetables?

Absolutely. Celery, mushrooms, parsnips, and turnips are all delicious additions that cook well alongside the roast.

Can I make this recipe ahead of time?

Yes. You can prepare all of the ingredients the night before and store them in the refrigerator. The next morning, simply place everything in the slow cooker and start cooking.

How do I make gravy from the cooking liquid?

After removing the roast and vegetables, pour the cooking liquid into a saucepan. Whisk together 2 tablespoons cornstarch with 2 tablespoons cold water, then slowly stir it into the simmering broth until the gravy thickens.

How do I know when the roast is done?

The roast is ready when it is fork tender and slices easily. If it still feels firm, continue cooking for another 30 to 60 minutes and check again.

Can I cook this on High instead of Low?

Yes. Cook on High for 4 to 5 hours if you’re short on time. For the most tender roast, cooking on Low for 7 to 8 hours is recommended.

Can I cook potatoes and carrots with a rump roast in the slow cooker?

Yes! Potatoes and carrots cook beautifully alongside the rump roast. They absorb the flavorful beef broth while becoming perfectly tender by the time the roast is finished cooking.

Can I make this recipe in a Crock Pot?

Absolutely. Crock-Pot is a brand of slow cooker, so the cooking instructions work the same whether you’re using a Crock-Pot or another slow cooker.
