Today, I’m sharing my favorite way to make roast beef in the oven. It’s perfect when you want something easy and delicious to serve for the holidays or to make a Sunday dinner a little more special.
There’s a reason roast beef is such a classic for family gatherings. You don’t need to be a professional chef or even have much experience cooking at all to make it. All you need is a rump roast, some common seasonings, and a baking pan. Once you have those things in place, it’s time to get cooking!
So how do you cook a rump roast? That’s what I’m here for! I’ve got all your answers—including what do to with those leftovers.
- Hands off method. Searing the roast in a hot oven and then turning the heat down to let it roast slowly means you don’t have to dirty a second pan.
- Classic seasonings. We’re keeping things simple here with classic seasonings that let the flavor of the beef shine. That means the leftovers have maximum versatility!
- Melt-in-your-mouth tender. No tough, chewy beef here!
Ingredients You’ll Need
Rump roast. For this classic recipe, I like to use rump roast, which is an affordable cut of beef that’s very tender. You can also use a bottom round, sirloin tip, or go all out and splurge on a boneless prime rib roast. Whichever you choose, look for a cut that’s labelled choice or prime and has some visible marbling for the best quality.
Garlic. I use a few cloves of fresh garlic for the best flavor.
Rosemary and Thyme. Using fresh herbs in your rub gives this rump roast recipe a fresh, modern vibe. You can substitute dried herbs if they’re all you have, but you will sacrifice some flavor.
Salt and Pepper.
You’ll also need a roasting pan that’s large enough to fit your roast. A meat thermometer is also helpful for ensuring your roast is cooked perfectly.
How to make a tender beef roast in the oven
Mix the oil and herbs in a small bowl to create your rub. Let this mixture sit a few minutes to allow the herbs to soften and infuse the oil with flavor.
Rub the herb rub all over the beef, making sure it’s completely covered. In addition to adding flavor, this will ensure the roast gets a beautiful brown crust on the outside.

Rest the beef before slicing to allow the juices to redistribute throughout the meat.
Pro tips for the best oven beef roast
- Allow the roast to come to room temperature before cooking it. This requires a little pre planning but will ensure the meat cooks evenly throughout. That way you won’t have to overcook the outside in order to get the center up to temp.
- Timing will vary depending on your oven as well as on the size and shape of your beef. Using a meat thermometer will give you the most accurate results. The internal temperature of your roast should reach 135ºF for medium rare, 145º for medium, and 150º for medium well. Remember that the temperature will rise another 5-10º as the meat rests!
- Plan to cook your rump roast for 30 minutes, plus and additional 30 minutes per pound.
