Did you know it is possible to cook perfectly sliceable and tender roast beef in the crock-pot? (In just a couple of hours?!)

I’ve been using my crockpot to cook fall-apart tender shredded roasts for years, as proven by two of our favorite roast beef recipes. However, it never before crossed my mind to try a method for slow cooker roast beef like this.

I originally planned to cook this roast using my favorite oven method. However, at the last moment, I decided to try improvising that method for the crockpot. It worked great and the roast was a huge hit.

How to Cook a Roast in a Crock Pot

It’s amazingly easy to make roast beef in the crock-pot and didn’t take nearly as long as I expected. From start to finish the whole thing to less than two hours.

After searing the meat stove-top with a generous amount of salt and pepper, I put it in the slow cooker on low.

Since it was the first time I’d followed this crock pot method I wasn’t sure how long it would take. Times like this are when I’m especially thankful to have a meat thermometer with an alarm!

Instead of having to check the roast frequently for doneness, I simply put the meat thermometer in and got busy with other tasks. A beep from the thermometer after 90 minutes told me the internal temperature had reached our ideal 140 degrees.

We like our beef closer to rare than well and usually closer to rare than medium. If you prefer yours a bit less pink, adjust the cooking time and final temperature accordingly.

It was hard to resist diving into the tender juicy roast right away but we managed to hold off long enough to let the meat rest before slicing it thinly.

I served the roast with roasted potatoes and roasted broccoli and the whole family gave the meal great reviews. I served the remaining beef with soft rolls for roast beef sandwiches a couple nights later. It was delicious both ways.

Leftovers are also delicious served on a tray of cold cuts, tossed into a salad or fried up with hash. There are so many uses for leftover roast beef that you’ll never be sorry to have extra.

Slicing Roast Beef

The only trick to this meal is slicing the meat as thinly as possible. To accomplish this, use the sharpest knife possible and a meat fork to hold the roast in place as you carve. Carve thin and even slices moving across the grain.

Be sure to let the roast beef rest for 10 to 15 minutes to allow the meat to reabsorb all the juices released during cooking. This also makes the beef easier to slice as it cools.


Roast Beef Slow Cooker Recipe

I enjoy the no-frills nature of this easy crockpot roast beef recipe While I love showstopping elaborate dinners as much as the next girl, sometimes the simple meals are the best.

If you feel like jazzing up your slow cooked roast a little without any extra work, check out Slow Cooker Italian Red Wine Roast Beef.  It takes a little more time to make that crock-pot roast, which is flavored with Italian herbs and rich red wine, but it’s well worth it.

You skip the searing step of my plan crock-pot roast beef recipe and leave the roast in the crockpot to cook in that delicious red wine marinade for 8-10 hours. To make up for that extra cooking time, this roast rewards you by filling your home with an incredible aromas as it cooks.

For something a little different, this Crock Pot Coca-Cola Roast looks tasty too. The soda is used to sweeten and caramelize the meat as it cooks while adding moisture.

While it’s not a slow-cooker recipe, while you’re on a roast beef kick you MUST try our favorite Southwestern Roast Beef. The roast is rubbed with a fire-y blend of New Mexico spices and sweet honey; it’s in frequent rotation for dinner at our house.

Looking for more fuss free dinner ideas for the slow cooker? You might also enjoy Crock-Pot Chicken Fajitas, Crock-Pot Balsamic Brown Sugar Pork Roast and Crock-Pot Mexican Pork.

Have you ever tried making roast beef in the slow cooker? Let me know how it turned out then give this recipe a try. You’ll end up with a plate full of flavorful and juicy roast beef that’s so tender it’ll almost fall apart on your fork.

I can’t recommend this slow cooker roast beef highly enough!

Kitchen Tip: I use this crock-pot and this thermometer to make this recipe.

Slow cookers or crockpots are an appliance of which I have more than one. If you are an avid slow cooker user like I am, you might understand the need for more than one. So, let’s talk about my favorites:

First up is this 6-quart slow cooker that has a locking lid. These crockpots are fantastic for transporting foods. Mine has gone everywhere from church potlucks to barbecues, game nights to Thanksgiving dinner. However, fair warning, these slow cookers run crazy hot. Low is closer to a boil than a simmer, the warm setting actually simmers. So trust me when I say HIGH is high.

My everyday slow cooker is this 8-quart Crockpot. It’s my go-to appliance for cooking large roasts and big batches of chili. Fun fact: did you know that a full 4-quart cooker, actually cooks more slowly than a half-full 8-quart cooker?

For just cooking a few pounds of chicken to shred for enchiladas or other smaller recipes, this 3-quart version is perfect.

Thanksgiving has become a breeze since I have mastered how to hold all of the side dishes using these medium-sized round slow cookers.

If you aren’t a fan of the idea of keeping more than one slow cooker in the house, these CrockPockets are a game-changer when it comes to preparing and holding multiple dishes at the same time. They slide into a standard 6-quart crockpot, dividing it into two sections that are perfect for serving different side dishes or keeping taco fillings warm for parties.

Perfectly Simple and Sliceable CrockPot Roast Beef

Perfectly sliceable and tender roast beef made in the slow-cooker.
Prep Time: 15 minutes
Cook Time: 1 hour 35 minutes
Total Time: 1 hour 50 minutes
Servings: 8 -12 servings


  • 2-3 pounds beef roast I used a top sirloin roast
  • 2 teaspoons kosher salt adjust to taste
  • 1 teaspoon freshly ground black pepper adjust to taste
  • 2 tablespoons olive oil


  • Heat the oil in a heavy skillet over medium heat. Season the roast generously with salt and pepper. Sear the meat in the hot skillet, about 3-4 minutes on each side, until the meat has browned. Sear the sides as well as the top and bottom of the roast. Remove from the skillet and place in the crock-pot. Insert an oven-safe meat thermometer into the center of the roast and place the lid on the crockpot.
  • Cook the roast on LOW until the temperature reaches 140 degrees. This took just 90 MINUTES for my roast. Depending on the temperature of your house and how hot your slow cooker cooks, it might take twice as long for yours. I set the alarm on my meat thermometer and couldn’t believe it when it beeped so quickly!
  • Using meat forks or sturdy tongs, remove the roast to a cutting board and tent it (or cover it with a large mixing bowl turned upside down). Let the meat rest 20 minutes before slicing it as thinly as possible against the grain of the meat. Enjoy!

    I just made this with a london broil cut of meat. I cooked it until it was 135 degrees. It is the MOST tender piece of london broil I have ever cooked! Thank you!!

  2. Jamie G says

    Super easy and delicious! I cooked it to 150°F and it was just how I like it – mostly pink with red at the middle! Now I need to sharpen my thin-slicing skills….any tips for that (other than “buy a deli slicer”)?? 🙂 Thank you!

    This recipe was excellent. My crockpot cooks at a higher temperature (on high) than it should so it was ready in less than 5 hours. The Worcestershire sauce was a bit too much for my husband so I will half it next time and just add extra to my dish. Awesome comfort food!5 stars

    This is my new “go-to” way to cook big hunks of beef. So tender and flavorful…..perfect for roast beef sandwiches with some fresh horseradish on a fresh kaiser bun. But i digress. Making it again today…plan on just slicing beef….a little A1 and some rice and a salad. Awsomeness!!!5 stars

    I just made a 2 pound eye round roast and I took it out at 130 degrees and let it rest for 20 minutes. Came out rare the way my husband likes it. He is on a low sodium diet so I used a rub with garlic powder, onion powder, rosemary, thyme and black pepper, no salt and quite tasty. Sliced it very thin for sandwiches.5 stars
