WHAT IS RUMP ROAST?
Rump roast is beef that comes from the cow’s rear end, near the tail. A rump roast weighs 3-4 pounds and comes from the top of the back leg muscle on the cow.
The muscle where the rump roast comes from gets continual use. It is lean with almost zero fat marbling throughout, making it a chewy and tough cut of beef.
However, a muscle on the cow that gets a lot of use is also very flavorful. Rump roast is easy to cook if done low and slow in lots of liquid or under pressure in a pressure cooker, such as an Instant Pot.
NAMES FOR RUMP ROAST
Rump roast is called by various other names, including:
- Standing Rump Roast (this rump roast has a bone in it)
- Round Tip Roast
- Bottom Round Roast or Bottom Round Oven Roast
Rump Roast in the Pressure Cooker
Unpackage the rump roast and allow it to rest at room temperature for 30-60 minutes.
Don’t skip this step – it allows the beef to rest and relax to cook more easily and evenly. Cut the roast into five chunks, then season each with the steak seasoning.
Add the tomato paste to the Instant Pot, then stir in the can of soup and water.
Place the seasoned pieces of roast into the soup mixture, then top the beef with the potato halves.
Choose the high-pressure setting, then set the timer to 30 minutes, bringing the Instant Pot to full pressure.
Use a natural pressure release for 20 minutes when the Instant Pot timer sounds.
If any pressure remains after 20 minutes, perform a quick release to remove it from the Instant Pot.
Carefully unlock the Instant Pot lid and remove it. Use a fork to test the beef to ensure it is nicely fork-tender.
Remove the meat and potatoes from the Instant Pot to a platter.
Use a spoon to skim the fat from the surface of the sauce in the pot. Or place the sauce into a fat separator to separate the fat from the sauce to make a delicious gravy.
Serve the roast with potatoes on the side, all drizzled with the warm gravy.
IS RUMP ROAST TENDER?
Rump roast can be juicy and tender if cooked low and slow in the oven (braised), slow cooker, or in. pressure cooker, like an Instant Pot.
What to do with rump roast
Rump roast is one of the best cuts of beef you can choose. Rump roast is delicious when cooked the first time and also as leftovers for other dishes.
How Long to Cook a Rump Roast
A 3-4 lb rump roast in the Instant Pot takes about 50 minutes.
The first thirty minutes are cooking in the Instant Pot. The next twenty minutes will be a natural pressure release.
Make sure not to skip the natural release. It makes the roast much more tender!
IS A RUMP ROAST THE SAME THING AS CHUCK ROAST?
A rump roast and a chuck roast are not at all the same. They are both beef roasts but come from very different areas on the cow.
A rump roast is classified as very lean and comes from the cow’s rear end. This musclue gets a lot of use, making it a tough muscle.
A chuck roast is classified as lean and comes from the shoulder of the cow. The chuck roast has more marbling and is, therefore, a juicier roast.
HOW TO CUT A RUMP ROAST
Before cooking a rump roast, you can cut it into quarters or even smaller pieces if desired. This will help the meat cook quickly.
Cut any roast into chunks to speed up the cooking process. This allows the heat can reach the center of the meat more quickly from all sides.
Place the roast onto a cutting board and use your favorite sharp knife. Cut the roast in half. Then cut each half in half so that you’ve got 4 chunks that are fairly even in size. Cutting each chunk as close to the same size as the others helps them cook evenly.
HOW TO SLICE A RUMP ROAST
Any time you slice a roast, slice it across the grain, not with the grain. Slicing across grain shortens the protein fibers that run the length of the roast. This makes it more tender to chew and a better eating experience.
You can also shred the meat into chunks if you prefer not to slice it.
WHAT TO DO WITH ROAST THAT IS TOUGH
When your roast turns out tough and chewy, remember these three words: SLICE, CHOP, SHRED.
- Slice the roast across the grain into VERY THIN slices, like deli meat comes. You can use the meat for making sub sandwiches, sliders, wraps, or pinwheels.
- Chop the roast into very small pieces. I like to add chopped cooked roast to mac and cheese or roast beef wellington packets. Or, add the chopped roast to salads to make them a main dish.
- Shred the roast in a food processor. It is perfect for making roast beef salad (think chicken salad or ham salad but with beef instead).
HOW TO COOK RUMP ROAST
You can easily cook rump roast low and slow, completely unattended, by braising it in the oven or a pot on your stove.
I like to cook my rump roast in a pressure cooker, like an Instant Pot, because I’m always in a hurry!
SHOULD RUMP ROAST BE BRAISED?
Braising rump roast is one of the best ways to cook a rump roast. It simmers low and slow in the braising liquid, such as broth, beer, wine, or any combination of flavorful liquids.
You can also make delicious savory rump roast in an electric pressure cooker, such as an Instant Pot.
IS A RUMP ROAST GOOD FOR POT ROAST?
Yes! Nearly any roast is good for making pot roast as long as you cook it low and slow.
Technically, any roast cooked in pot is considered pot roast! My favorite roast for making pot roast is the CHUCK roast. I’m a big fan of chuck roast because it is flavorful from all the great marbling (fat!) it has.
HOW DO YOU KNOW WHEN A ROAST IS FORK-TENDER?
When a roast is fork-tender, a fork can be inserted into the cooked meat. With a gentle twist, the meat gently gives to the pressure and comes apart.
If you insert the fork into the roast and you feel resistance, this indicates the roast is not ready. The roast needs to continue to cook until it is more tender.
WHY TO USE A FORK TO TEST A ROAST FOR TENDERNESS
A fork has dull tips, so it will not slide easily into the meat UNLESS it is nicely tender.
Some cooks use a knife tip to test a roast for doneness. This can deceive us since a sharp knife tip will slide into nearly anything.
This will give you a false read and a roast that hasn’t cooked long enough to be tender.
WHAT TEMPERATURE SHOULD A RUMP ROAST BE COOKED TO?
I always recommend testing tough roasts with a fork for doneness, not by internal temperature.
When a roast is very fork-tender, you know the roast is tender and ready to eat.
HOW TO COOK RUMP ROAST WITH VEGETABLES
Add vegetables to the pot when the roast gets nicely fork-tender.
The roast will continue to cook until it’s fully done without over-cooking the vegetables.
Adding the vegetables at the beginning of the rump roast cooking time will result in overcooked vegetables.
DOES A RUMP ROAST SHRED?
Yes, a rump roast will shred if cooked until it is very fork-tender.
Any roast, whether beef or pork, will shred if braised low and slow until fork-tender.
HELPFUL TIPS FOR COOKING THIS RUMP ROAST RECIPE
Cutting the roast into chunks helps the meat cook much more quickly. You can do this with any roast to make it cook faster, no matter your chosen cooking method.
Leaving the skin on the potatoes instead of peeling them helps them hold together. After cooking under pressure with the meat and liquids in the pot, the skins become super tender and easy to eat.
When cooking any roast, give it some good beauty rest on the counter BEFORE you cook it and AFTER you cook it. This is more important than you may realize! Rest before meat cooks allow it to accept the heat much more easily so it can cook evenly. Rest after meat cooks lets the cooking juices redistribute throughout the meat’s fibers so it’s juicy and tender when eaten.
When cooking ANY meat in the Instant Pot under pressure, be sure to use a natural release. Never use the quick-release on meat. This gives the meat the beauty rest it needs in the Instant Pot to rest, relax, and finish cooking. When the timer sounds, leave the Instant Pot and let your meat REST.
