Slow-Roasted Oven Recipe For Perfect Roast Beef

Updated on March 18, 2016

Super Easy Oven-Roasted Roast Beef

This recipe is so basic and so easy that it is a keeper for me! I actually was skeptical about the cooking time that was listed in the recipe I had seen on and am glad that I did not follow the recipe exactly as the cook time listed there was far in excess of what was actually needed.

By tweaking the recipe a bit, I ended up with a rump roast that was super moist and wonderfully tender. The leftover roast cut paper thin will be perfect for using in sandwiches such as roast beef sandwiches with Swiss cheese, in a panini, or as an open faced roast beef sandwich with leftover gravy.

Oven-Roasted Roast Beef And Gravy


  • 3 to 3-1/2 lb. boneless rump roast
  • Olive oil
  • Peeled garlic
  • Salt and pepper
  • Herbs (optional) - tarragon, thyme, marjoram, rosemary in combination or to taste


  • Drippings from drip pan
  • Red wine or port, water and/or beef stock (divided - about 1/8 to 1/4 cup - about 1 cup total liquid used but tweak to preference of thick or thin gravy)
  • Cornstarch (about 1 tablespoon)
  • Worcestershire sauce (dab) - optional


  1. Let the roast stand for about 1 hour at room temperature but keep in wrapping. Take out when ready to put in oven.
  2. Preheat oven to 375 degrees.
  3. Insert little slivers of garlic to taste at points around the roast – stab a little hole and insert the slivers.
  4. Pour a few teaspoons of olive oil on the roast and smear the roast on all sides with the olive oil. Then salt and pepper it to taste on all sides. Add herbs at this point if desired to the rub.
  5. Put the roast into the oven and set it directly on the oven rack. NOTE: Mine was a rather triangular cut and wanted to fall over so I propped it against the oven thermometer to keep it upright. The idea here is that you want the fat side up so that the fat will run down over the roast as it cooks and keep it moist and tender.
  6. Place a drip pan under the roast to catch the drippings for the gravy you will make later.
  7. Cook at 375 for 30 minutes only. Again, the roast is not in a pan but right on the oven rack so the drippings will be going down into the drip pan below. You do not need to turn the roast at all.
  8. Reduce the temperature to 225 degrees. NOTE: I used a 3-1/2 pound roast and it says in the recipe to cook the roast another 2-3 hours. Luckily, I have a meat thermometer which I insert with a probe and the monitor sits outside the oven. I did not even cook the roast 1 hour and it was registering 135 so that is why I think the cooking time is off in the recipe.
  9. I would use a meat thermometer of any kind to check the temperature after 30 minutes when you reduce the heat to 225 degrees. You want to get a reading of 135-140 degrees. The roast will continue to cook once it is outside the oven so that temperature would be for medium rare. If you wanted the end result to be medium, then you would let it go to about 150-155. The meat will probably go up at least another 5 degrees upon being removed from the oven but always check with a thermometer.
  10. Once removed from the oven, cover with foil until ready to carve.

I did find this recipe so simple to do and you could increase the time and do larger roasts quite easily. I was worried it would make a frightful mess of the oven but with the drip pan, it really was okay and there was not a lot of smoking because the temperature was fairly low after the initial 375 degrees for 30 minutes.

Also of note, the recipe suggests that if you want more drippings to accumulate in the drip pan, turn the heat down further to 175 and that should ease out more drippings. I found the drippings adequate at the above temp but recipes are for tweaking.


  1. Take the drip pan out of the oven and place over medium heat (or add a little beef broth or water/wine to the drippings and stir then scrape into a small pan).
  2. If you do not have much in the way of drippings, you can always add a little butter to make up for the drippings.
  3. Add water, beef broth, red wine or port to the drippings and deglaze (loosen the drippings and combine into the liquid). I added about 1/8 to 1/4 cup at this point but my measurements here are not exact. It is all a matter of preference for how much gravy you are making and deciding how thin or thick you want it. This is just to get the base going but in the end I think my total liquid use was about 1 cup.
  4. Remove any pieces of garlic that may have fallen in. I added a little dash of worcestershire sauce to the mix as well.
  5. Dissolve about a tablespoon of cornstarch in a small amount of water and add to the drip pan, whisking all the while. You will see it start to thicken almost immediately so add more water, beef broth, red wine or port to taste.
  6. Add salt and pepper to taste.
  7. You can also add herbs to taste such as tarragon, rosemary, thyme or marjoram if you have not put on the roast as a rub. They all give a different flavor individually or a combination of all is great too.

I served this with roasted red potatoes (skins on) and some baked butternut squash. The roast will serve 4-6 but if it is just 2 of you, you will have plenty left over for lunch meat for sandwiches!

Recipe for Roasted Red Potatoes


  • 4-8 red potatoes depending on size - scrubbed/skin on
  • Olive Oil
  • Herbs of choice (try tarragon, marjoram, thyme, sage, rosemary)
  • Salt and pepper
  • Cooking spray


  1. Heat oven to 400 degrees.
  2. Spray an 8 x 8 square pan with cooking spray.
  3. Scrub potatoes and remove any blemishes but leave skin intact.
  4. Chunk the potatoes into a bowl or place in a Ziploc bag. (Use as many as will fit comfortably without crowding into the 8 x 8 square pan - there will be a little shrinkage but the size of the pan is about right for roasted potatoes for 2)
  5. Add a few teaspoons of olive oil. Sprinkle with herbs of choice (I used tarragon, rosemary, thyme and marjoram).
  6. Add salt or pepper to taste or just leave as is with herbs and oil.
  7. Stir or shake/toss to coat in Ziploc bag. (I have also at this point instead of the olive oil and herbs added just a few teaspoons of an Italian dressing such as Paul Newman's and it worked just as well)
  8. Turn out into the pan and place in oven. Cook uncovered for 20 minutes.
  9. Flip the potatoes over and, loosen any browning in bottom of pan, spray with cooking spray and return to oven for 20 minutes.
  10. Check on the potatoes and bake longer if more browning is desired.

NOTE: You can also roast the potatoes at 425 or 450 degrees, but be sure to watch for browning and cooking time will be reduced per side.



  • Butternut squash
  • Butter if desired
  • Salt if desired
  • Cinnamon if desired
  • Brown sugar if desired

NOTE: I find that the flavor of butternut squash is so wonderful that I don’t add butter or brown sugar but some people like squash with those additions. I would recommend not going too heavy on it though with butternut as it is a very flavorful squash.


  1. Preheat the oven to 350 degrees.
  2. Slice the butternut squash in half the length of its body. Scoop out the seeds. (You can roast the seeds if you like after cleaning much like pumpkin seeds).
  3. Sprinkle with salt or even a tad of cinnamon if desired. If using butter or brown sugar, do a smear over the orange flesh of the squash.
  4. Wrap securely in foil (I always cook mine wrapped in foil but in a pan or on a cookie sheet to prevent spills in the oven).
  5. Bake in the oven for 1 hour although it is all dependent on the size of the squash – if you squeeze the squash it will be soft when you press on it and it is done.
  6. Simple scoop out – if you have cooked without butter and brown sugar, you can scoop out the flesh of the squash and add a tad of butter and brown sugar, salt or spices to taste, but I find butternut squash to be just perfect ‘as is’.
  7. Leftover butternut squash: I have used some of it to stir into soups and stews or added it to potpies rather than flour or potatoes because it has such a great flavor. Also delicious as a soup – and the health benefits are great!

      Try cooking it long and slow (forget the thermometer) and you will be surprised how it melts in your mouth. My aunt gave me her recipe (similar to this)over and over because I "knew" something was wrong. Turns out she was indeed cooking it at 225 for 3-4 hours. It won't be pink, but will be tender and fall apart - melt in your mouth like butter.

      I made this too except using a roasting pan and it was absolutely delicious!! Thank you!

      This makes me think of the best part of the Dr. Suess classic: "And he, himself, the Grinch, carved the roast beast." :)

      This looks like one of the best ways to cook a difficult cut of meat-- thanks for sharing!

      Thanks cookbooks for the informative comment.

      Dokka - There are many ways to do anything and this recipe in fact does not call for the meat to be seared but thanks for pointing out that it usually is.

    • Dokka 5 years ago

      Aren't you supposed to seal the meat in a hot dry frying pan first? Thought all good cooks would know that!

    • cookbooks 5 years ago

      Good looking hub, will be able to tell more when the ads are placed. Well written and informative. The hub looks good and has great information included. The photos are really nice. Maybe the first two should be one or half size. This hub should do well.

      Sounds like a good recipe. I like how you point out to bring the roast to room temperature first. That's a step I think a lot of people miss and it hurts the end result.

    • akirchner profile image

      Audrey Kirchner 6 years ago from Central Oregon

      Charlayne - I totally agree and after I did it on the rack itself, I decided it would be more efficient to use the pan with the roasting rack!

    • Charlayne 6 years ago

      I have a couple of nice roasting pans with the racks on them. I think I'll make the roast we have just like the recipe except using the roasting rack. I have problems with getting down to scrub the oven as it is and if I mess up, I want a way to clean it easier. Other than that, OMG that sounds yummy!

      Great - it works really, really well but I was so skeptical with it sitting on the oven rack! Should have been at your house for dinner!

      Yes - I don't know 'nuttin' about mutton though in terms of fat but with roasting a chicken that way, I would have a large drip pan! And you would just need to make sure the internal temperature was correct still. I think my lunch meat blog has the internal temps for everything but mutton! Let me know if you try it if it works....thanks - Audrey

      Mine would have been too had I not been watching that thermometer....Bob said to me as he passed it in the kitchen 'what temp did you say that was supposed to be because it's already at 129' - otherwise I would have had another shoe leather roast! My son was telling me about getting one of those serrated knives too for cutting it paper thin so think I'm going to be putting that on my Christmas list! We got that roast for $10 and we had it for dinner and sandwiches, then Bob had more last night for dinner and we still have a pretty good bunch of it left. Can't beat that!

      Thank you - it actually was delicious and I was very surprised because a rump roast is not the most expensive cut of meat but slow cooked, it was just perfect! Thanks so much for stopping by.....Audrey
