What makes this recipe such a winner?
- The PERFECT pot roast: If you are intimidated by roast beef because it is tricky to get just right then this is the beef recipe for you. Technically it is not a roast but a beef pot roast since it is cooked in a slow cooker.
- It is almost hands off, practically a ‘dump and go’ recipe. After some initial prep, the meat simply cooks slowly for several hours until it becomes perfectly tender and succulent.
- Finally a roast beef recipe that comes with gravy built in! The flavor-packed broth in which the roast cooks becomes the totally addicting thick gravy you will want to bathe in (or maybe that’s just me)
- You can also cook potatoes and other veggies at the same time – one less job to do!
Which is the best cut for slow cooked roast beef?
You can use any cut of beef joint that’s suitable for roasting or pot roasting, from boneless chuck roast (that’s the same as braising steak in the UK) to other budget friendly options such as brisket and topside. I usually order my beef joint from Amazon Fresh – such good quality!
Make sure your cut of beef will fit in your Slow Cooker – as you will see from the recipe video my joint was rather mahoosive! You can cut it in half if necessary.
Different beef cuts will yield different results. If you prefer a fall-off-the-fork tender beef roast then go for a brisket joint. If you want to slice your beef then a topside or top round will be a better option.
Remember that beef will shrink slightly as it cooks so buy medium-large joint, allowing for at least 200g (7oz) meat per person if you’re planning to feed the entire family this delicious meal.
If you have the GreenPan Slow Cooker you can brown the beef directly in it saving washing up and energy!
- Beef stock (beef broth) – I usually use Knorr Stockpots but you can use a stock cube or your favorite fresh or canned beef broth, preferably a low sodium one. Check this is gluten free if that is a concern
- Worcestershire sauce, Balsamic vinegar and soy sauce (use Tamari for GF version)
- Concentrated tomato paste
- Onion and garlic
- Bay leaves
- Carrots – these add depth of flavor to the gravy and you can serve them on the side, win-win!
- Potatoes – these are optional. I actually prefer crispy roast potatoes with my roast beef so I usually cook these separately in the oven or an Air Fryer.
- Cornflour (cornstarch) to thicken the gravy. You can also use Xanthan Gum.
HOW TO MAKE SLOW COOKER BEEF
Full measurements and instructions can be found on the printable recipe card at the bottom of the page. Please take a look at the steps and video before attempting this recipe!
STEP 1. Pat the beef dry with kitchen paper and season well with salt and pepper. Allow your beef joint to come to room temperature before cooking.
STEP 2. Spray a large skillet or shallow casserole dish with olive oil spray and sear the beef on all sides. This can take up to 10-15 minutes, but adds so much flavor. You want to trigger the Maillard reaction – in layman’s terms you want to brown the beef until nicely colored.
STEP 3. Set the beef aside and deglaze the bottom of the pan with white wine, red wine or beef stock, scraping any browned bits into the broth with the back of a wooden spoon. This is where a lot of the flavor comes from so don’t skip it!
STEP 4. Add the onions and carrots and stir until they get a bit of color and and almost all of the liquid is gone.
STEP 5. Add beef stock (broth), soy sauce, balsamic vinegar, Worcestershire sauce, tomato purée, minced garlic, salt and bay leaves. Stir to combine.
STEP 6. Add the beef and then the vegetables, pushing them down into the liquid. Top with extra hot beef broth to come up halfway up the side of your joint.
STEP 7. Cover the slow cooker and cook for 5 – 8 hours on LOW or 3-6 hours on HIGH depending on the beef cut and your preferences. If your crock pot has a ceramic insert it will likely need to cook for longer – modern slow cookers which allow for searing heat quicker and therefore the total cooking times are shorter.
STEP 8. Use a slotted spoon to remove the vegetables from the slow cooker. Check the beef using a meat thermometer (see guidelines below) or by piercing with a knife – it should be tender.
ROAST BEEF INTERNAL TEMPERATURE
The best way to check your beef is cooked to your liking is to check the temperature with a digital thermometer. Insert the probe in the thickest part of the joint and check the temperature against these guidelines.
Medium rare – 55°C (131°F)
Medium – 60°C ( 140°F)
Medium-well – 65°C (149°F)
Well done – 70°C+ (158°F)
Best ever beef gravy
A good gravy can make or break your roast beef dinner! It’s definitely one of the best things about this slow cooker beef roast recipe. All you have to do is strain all the braising liquid from the slow cooker into a saucepan discarding any solids (but hold on to carrots and potatoes if used).
Stir in some cornstarch slurry and bring the gravy to a rolling boil over medium-high heat. Reduce to a low heat and simmer gently for 10-15 minutes or until slightly reduced. Taste and season if needed.
Slice the beef against the grain and arrange on a platter with the carrots (and potatoes if you have added any). Drizzle with gravy and garnish with fresh chopped parsley. Serve the roast with extra gravy and stuffing balls on the side.
TIPS FOR BEST-EVER SLOW COOKER BEEF
Brown the beef before cooking
This triggers the Maillard reaction which adds tons This triggers the Maillard reaction which adds tons of flavor to your pot roast. If you are really short of time you can ‘dump and go’ skipping this step but for the best flavor in this tender roast beef, sear the meat first.
Deglaze the pan
Pour a generous splash of wine or broth into the hot pan after you have set the beef aside. Use the back of the spoon to scrape any browned bits into the stock. These are called the “fond” and can create the base for a pan sauce.
Do the prep work the night before
Add all the ingredients to the slow cooker, allow to cool and place in fridge overnight (in the slow cooker or a suitable container). The next day turn your cooker on and forget about it for at least 8-9 hours. The roast will take a bit longer if cooked straight from the fridge.
LEFTOVERS AND STORAGE
Keep any leftover meat for up to 4 days in the fridge and use in sandwiches, pasta bakes (try my Stroganoff pasta bake or this yummy Philly Cheesesteak Soup). If you have any leftover gravy you can freeze it – pour cooled gravy into an ice cube tray and freeze until solid. Pop the cubes out into a freezer bag and use within 3 months.
