What’s To Love About This Recipe 

  • This traditional roast doesn’t have to be reserved for Sundays! It’s simple enough to prepare for any day of the week but is also an elevated meal that could work for holiday meals and special gatherings.
  • With the slow cooker, preparing a delicious roast does not have to take lots of effort! All you need is a few minutes to brown it to develop a seasoned crust. Then, set it and forget it for the rest of the day.
  • This slow cooker version of roast beef is the best choice to ensure the meat doesn’t turn out tough or chewy. You can cook it low and slow until it is perfectly tender.
  • Roast beef from a round roast is a nice cut for slow cooking because it has minimal fat and won’t be greasy at the end. With just a few added seasonings, oil, and a splash of balsamic vinegar, you can achieve an incredibly delicious roast with little effort!

Ingredients Needed 

  • Round beef roast – I use a 2-pound eye of round beef roast in my 4-quart multicooker. I like a less fatty cut of beef for this recipe, which is what you get with the eye of round. Other options that will work are top round, bottom round, or you could even go with a rump roast.
  • Olive oil – Use some olive oil to help brown the meat and create a seasoned crust that keeps the meat tender and juicy. 
  • Fresh rosemary – Use 3 stalks of fresh rosemary and remove the leaves to chop up for the seasoning.
  • Minced garlic – Minced garlic is an easy addition and adds texture to the seasoning rubbed on the roast. 
  • Sea salt – Sea salt also adds some extra texture to the seasoning rub.
  • Fresh ground pepper– Use a pepper grinder to crush peppercorns or coarse pepper for a burst of fresh spice.
  • Balsamic vinegar – Use balsamic vinegar to get all the browned bits from the pan or multicooker, and add every bit of delicious leftover glaze!

Note: While the general serving “rule” is about ½ pound of boneless roast per person, I find you can estimate slightly less, especially considering extra side dishes and whether or not you are feeding kids. I always like to have some leftover roast for my family. Since we usually have 3 people eating dinner on any given night, a 2-3 pound roast is perfect. 

How To Make Slow Cooker Roast Beef

pro Tips

  • Don’t skip the browning step! You will definitely want the outside of the roast beef to have a nice crust or sear, which helps seal the juices. Use your multicooker to save an extra dish to clean, or a simple skillet will work just fine, too!
  • Using balsamic vinegar to deglaze the pan adds a nice burst of flavor to the roast. Deglazing is also important for the multicooker to prevent any burning on the bottom of the pan.
  • Be sure to let the meat rest for the allotted time to preserve the juiciness of the meat!
  • If the roast is still tough, cook it longer until it is easy to shred. Beef will become shreddable at about 205 ℉.
  • Cook to 145 ℉ for medium or 150 ℉ for medium-well. Keep in mind, for slow cooking, judge doneness more by the tenderness of the meat and cook longer if needed.

Recipe Substitutions and Variations

  • Other meat cuts that work well for this roast beef recipe are top round, bottom round, or a rump roast.
  • Try swapping out the fresh rosemary for other favorite fresh herbs like thyme or sage.
  • Add some root veggies like roughly chopped carrots or parsnips to cook with the beef. Be sure not to overcrowd the slow cooker – the vegetables should fit comfortably around the roast.
  • If you’d like to make gravy to serve with the roast beef, save the cooking liquid, heat it, and whisk it with cornstarch or your preferred flour until it reaches the right thickness.

How To Serve Slow Cooker Roast Beef

In my family, we’re accustomed to a holiday roast for all of our special occasions. Maybe you’ll want to try this recipe for your gatherings, too!

Whether a fancy dinner or just a weeknight, a potato or veggie side is a must. Try Slow Cooker Creamy Garlic Mashed Potatoes or Slow Cooker Gratin Potatoes with a veggie like Lemon Pepper Roasted Asparagus. Add some toasty bread and a side salad if you like!

Leftover roast beef will also be delicious on cold sandwiches or toasted sandwich melts with a sharp or smoky cheese and a rustic mustard.

Storing and Reheating

Store leftover roast beef in an airtight container in the fridge for up to 3-4 days. Freeze sliced roast beef in a sealed container for up to 3 months.

Reheat in a skillet on low or in the microwave on low power so it does not overcook. If needed, add a bit of water or broth to keep the meat moist while it reheats.

    Hi, I just wanted to tell all of you that I have tried this recipe twice: I followed all the steps in the recipe but then wrapped it in foil and put it in the slow cooker. Once, I added some beef stock and once I did not. Both times were a mouthwatering success… but when I do it again (next week most probably) I will do away with the extra beef stock as it truly does not need it. Thanks again.

  2. Hi, I was reading the reviews and as I am planning to try out this recipe for Christmas lunch I was wondering if I should wrap the beef roast in foil with all the ingredients inside, Would this prevent it from getting dry? and would it still cook well. I have already tried pork roast in foil in a slow cooker and it worked perfectly, but never roast beef. Thanks

  3. Is there another herb on this besides rosemary? From the pictures, it looks like there is a leafy green as well.

    I made this today with a couple of alterations because of the reviews.

    1 I added a cup of beef broth

    2 I checked it after 6 hours it was at the perfect fall apart tender with somewhere between a medium to medium well doneness.

    This is the favorite roast I have ever made and will now be my new go too.

    Thanks for the guidance.

  5. I had the same problem as Andi. I even added a little broth to be sure it didn’t dry out. It was a total flop. It was so dry and came off in chunks rather than in slices. I was happy to have the broth in the bottom to pour over the roast prior to serving. Without that it would have been inedible.

  6. I want to make this for Xmas this year, but i’m a little nervous considering that there doesn’t seem to be any liquid in the crockpot. Would that dry out the meat?

    And how many pounds of meat should I buy to serve 10 people?

    1. Hi Sharon! You can certainly add a cup of beef broth to the bottom of the slow cooker and this will help keep it from getting dry. I think a general rule would be about 1/4 – 1/3 pound meat per person and I always like to have a little extra. I’d probably go for 3 to 3 1/2 pounds for 10 people.

  7. Thank you for a great recipe. I put this in the crock pot last night for lunch after church. It was done this morning, but stayed on warm until we were ready to eat. The flavor was wonderful and the prep time was not bad. I will add this to my “go to” recipes. Just wish there had been leftovers! I want to give it 5 stars, but they won’t light up.

    This beef meal was terrible! The beef was totally dry. The recipe says to cook 8-9 hours on low. I checked it at 7 and it was already ruined! It didn’t slice, either. It was more like shredded beef…gross!
    I used a good piece of meat and it was a waste of money. Very disappointed!

    1. Hi Andi. Wow, that doesn’t make much sense at all. Have you checked the temperature of your slow cooker? I can’t imagine any reason for a roast to be overcooked on low for 7 hours unless the slow cooker was cooking warmer than it should be (that can happen) or if you used too large of a slow cooker (if it’s not full enough the food will cook too fast). What cut of beef did you use?

          1. Could have seared it too much and cooked through too much of the meat leaving less inside circumference to need to be cooked! My crockpot runs hot. Even on low. I’m trying this today but I’m going to aim for 5 hours cause i did 7 last time and it was super dry also! I think the newer technology typically runs hotter. The flavor was great just cooked too long!
