How To Make A Tender Beef Rump Roast In The Oven

Step 1: Prep Your Beef Roast

Take the roast out of the fridge and unwrap it at least 1 hour before you plan to put it in the oven. We will be adding the topping right away. We want to allow it to rest with the marinade on it and come to room temperature so that it cooks more evenly.
Mix the worcestershire sauce, brown sugar, garlic, salt and black pepper in a small bowl. Set this aside.
Rub the roast with olive oil.
Rub the worcestershire sauce mixture over the entire roast.
Allow the beef roast to rest at room temperature for the full hour.

Step 2: Cooking Your Rump Roast In The Oven

Heat oven to 425 degrees Fahrenheit.
Place roast directly on the middle oven rack, fatty side up. Place a roasting pan on the rack below to catch the drippings.
Cook in a 425 degree oven for 15 minutes. Then reduce the heat to 325 degrees for the remaining cook time.
Cook for about 15 minutes per pound. A 3 pound roast will need about 1 hour total (45 minutes more at 325 degrees) and a 4 pound roast will need about 1.5 hours total (1 hour, 15 minutes more at 325 degrees). However, the thickness of the roast will influence the cook time. So check the temperature of the roast when you are nearing the end of the expected time.

Step 3: Serving Your Beef Roast

Insert a meat thermometer to check for doneness. Cook until the internal temperature reaches 145 degrees Fahrenheit for a roast done medium. (130 degrees is for rare meat, 155 is well done meat – keep in mind that well-done meat may be more tough) Remember that the temperature will continue to rise slightly after you remove the roast from the oven.
If you have any liquid on the bottom of the pan, save it if you'd like to serve the roast au jus.
Place the roast beef on a cutting board. Cover it with aluminum foil.
To have the juiciest pot roast, allow the cooked roast to rest for 15 minutes before carving into thin slices with a sharp knife.

Popular Substitutions & Additions

If you want to add a little more tang to your spice rub, dry mustard powder can be added. You'll want to use about a tablespoon, or if you want to add a little more sweetness, dark brown sugar is the way to go.
Try adding sliced onions, potatoes, carrots, parsnips, turnips, or other root veggies if you like adding veggies when cooking your beef rump roast. You will want to add them around the last hour and a half. Make sure the veggies are all at room temperature, so you don't bring down the oven's temperature.
If you are not a fan of Worcestershire sauce, try soy sauce! It has the same flavor profile and can be substituted one to one in most recipes.

How To Reheat & Store Cooked Rump Roast

Best Way To Store Oven-Baked Rump Roast Leftovers

If you are able to salvage any leftovers, you'll want to store them in an airtight container in an au jus that was produced while cooking to keep it tender or wrap it in tin foil.

How Long Will Beef Roast Last In the Fridge?

This beef roast should stay good in the fridge for 4-5 days after roasting.

Can I Freeze Rump Roast Once it's cooked?

Yes! You can freeze it for up to 6 months, but it will be the best quality if you freeze it for no more than 3 months. You will want to wrap it tightly in aluminum foil and make sure it has cooled completely to avoid frostbite and excess moisture.

How To Reheat Your Rump Roast Without Drying it out

One of the challenges of reheating a roast that has already been cooked is moisture loss. You'll want to avoid this by using a slow cooker to slowly bring it back up to temp with a bit of beef broth or au jus. You can also place it in a baking dish with about 1/4 cup of beef broth, cover with foil, and heat it until just warm at 325 degrees. The broth will help keep it tender and juicy.

Oven Roasted Rump Roast FAQs

How long should you cook a rump roast per pound in the oven?

If you have a rump roast that weighs less or more than 3-4 pounds, you'll adjust the cooking time. A good rule of thumb is 30-35 minutes per pound at 350°F or until it reaches the desired internal temperature.

How do I know my rump toast is done?

Depending on how "cooked" you like, your meat will dictate when it's done. You will need a meat thermometer to accurately gauge the internal temp. 145°F makes for a nice medium roast and helps keep it tender and juicy. If you like your meat DONE, then you will want to cook it until it reaches 155°F – this may result in a drier, tougher roast.

If you like a nice med-rare, go for 135°F. Keep in mind the cooking process continues after it is removed from the oven, so you may want to take it out just shy of the desired internal temp.

What's the best way to slice beef rump roast?

When it comes to slicing large cuts of beef, it's best to slice it across the grain in slices no more than 1/4 of an inch thick. This will give you more tender pieces of meat. It seems crazy, but how you slice your beef can make all the difference in texture, chewiness, and tenderness.

Could I make this roast in a crockpot?

Yes! The slow method of a crock pot (or slow cooker) is another great way to produce tender roast beef . You may want to sear the meat before placing it in the crock pot. Oil and season the meat. Place a cast iron pan (or a dutch oven, or even a large skillet) on the stove top and heat it to medium-high heat. Sear the roast on each side, until it is browned. Then place it in the crock pot. You will need to add liquid to the pot. I would recommend 2 cups of beef broth (or substitute red wine for ¼ cup of the beef broth). You could even add some potatoes and carrots for a complete easy dinner. Cook it on low heat for 8 hours, or on high heat for 5 hours.

Could I make this roast in my Instant pot?

Yes! You will want to saute the roast first, which you can do right in your instant pot, using the saute function. Add a Tablespoon of oil to the instant pot, turn on the saute function, season the roast and then set it into the hot oil. Turn it so that all sides brown. This will add great flavor to the roast. Remove the roast so that you can deglaze the pan. Add 1 cup of beef broth (or stock) to the pot and deglaze the pan (use a wooden spoon to free up the brown bits that are on the bottom of the pot). Return the roast to the instant pot. The cook time will be 20 minutes per pound. Allow for at least 10 minutes of natural pressure release.

I can't find a rump roast – what other cuts of beef will work with this recipe?

Tough cuts work well with this recipe because of the slow cooking. You do not need lean meat to get the perfect roast beef. Chuck roast or round roast will work just as well.

I don't care for Worcestershire sauce – is there something else I could use?

Feel free to use a mixture of your favorite herbs. Rosemary and thyme are especially nice with roast beef.
What is the best way to reheat roast beef? Heat the oven to 325 degrees. Wrap the meat in foil or place it in a baking pan with some of the juices from the meat (or beef broth). Cover the pan with a tight fitting lid or tin foil. Heat it until heated through (10 to15 minutes).

I don't have any liquid in the pan below my roast to make au jus – what can I do?

Beef broth, or beef stock make a fine alternative to au jus. Or you could prepare a broth using beef bouillon cubes or powder. This will be helpful if you are planning to use the leftovers for roast beef sandwiches and you need something to dip them in.

Should I use light or dark brown sugar for the spice rub?

You can use either dark or light brown sugar for this recipe. Dark brown sugar is heavier on the molasses (it has twice as much) giving it more of a caramel flavor. Depending on the flavor profile you are going for is which one you should use.

Can I use regular white sugar if I don't have brown sugar?

I don't recommend using white sugar in place of brown sugar for this recipe. Honey would be a better substitute and goes well with the Worcestershire sauce.
