Slow Cooker Roast Beef

Slow Cooker Roast Beef with potatoes, carrots, celery stalks, onions and garlic, cooked in a rich beef broth on a high temperature until the beef is so tender it simply melts in your mouth and the veggies are perfectly cooked. Turn the beef broth into a delicious gravy to accompany the roast, and you have a fantastic family-friendly meal that is hearty and comforting. No searing needed, this is one of those dump-and-go slow cooker recipes that are as easy as can be.

Although you can enjoy a hearty meal in any season, there is something about the cold weather that makes us seek comfort food to warm us up and fill us with the goodness we need to face the long Winter.

And while I absolutely love a good roast beef in the oven, especially for our Sunday roast, but also for special occasions, this slow cooker roast beef comes with the benefit of "dump and go", as you can literally set the slow cooker on, and job done, wait for dinner to be ready.

Sure, searing the meat does add flavour to the dish, but it also adds to the cooking time, and if time is the one thing you don't have, simply skip the searing bit, and just add everything to the crock pot, you will still get lots of flavour.

I opted to cook this slow cooker pot roast on high, and it was ready in 5 hours, but if you choose to cook it low and slow, like overnight, then you should cook it for 10 hours, depending on how big the chunk of beef is.

Adding vegetables to the crock pot to cook at the same time with the brisket means that you don't have to cook them separately, thus adding to the cooking time. Everything goes in one pot, the perfect family dinner that is 100% hassle free!

Ingredients used

• beef brisket - or boiling beef / beef for stewing, it's literally a big chunk of beef that is best cooked slowing in order to become tender. No quick cooking, or the meet will be way too tough to be enjoyed
• potatoes - I used baby potatoes cut into half, but regular potatoes can be used too, and chopped either in quarter or big chunks, depending on their size
• carrots - peeled and chopped into big chunks
• onions - peeled and quartered
• garlic cloves - just peeled, they can go in whole
• beef broth/stock - to give the beef a rich flavour
• tomato paste - to add a natural sweetness to the broth, and also a deeper colour
• Worcestershire sauce - works brilliantly with the broth to give a depth of flavour
• salt and pepper - to taste
• Italian dried herbs - or any other dried herbs of your choice
• cornflour - corn starch, to thicken the broth into a gravy-like consistency

Slow cooker roast beef cooking time calculator

The time needed for the beef to be ready depends entirely on the weight of the beef chunk. Most meals in the slow cooker are ready in between 3-5 hours on high, and 8-10 hours on slow.

For the brisket that weights between 1 to 1.5 kilos or 2 to 3 pounds, you will need to cook it for 4-5 hours on high, or 8-9 hours on slow.

For 1.5 to 2 kg or 3-4 pounds, you will need to cook it for 5-6 hours on high or 9-10 hours on low.

A regular sized slow cooker should take a brisket of 2 kilos, although you probably can't fit much else in. The beef chunk I used weighted 1.4kg, so I cooked it for 5 hours on high.

Step-by-step photos and instructions

• Add the beef to the slow cooker, and season it with salt, pepper, dried herbs and add the tomato paste
• peel and chop the potatoes and carrots in chunks, and add them to the crock pot together with the peeled and quartered onions, peeled garlic cloves and celery stalks
• mix the cornflour with 2 tablespoons of the beef stock and mix well, then pour it into the slow cooker with the rest of the stock and Worcestershire sauce
• place the lid on and cook on high for 5 hours or on low of 10 hours

Expert tips

The beauty of the slow cooker is that you can set it on and not worry about it until the food is ready. Do not be tempted to check on it too often and remove the lid, as it's that steam that helps the cooking process.

Allowing the steam to escape often will delay the tenderising process, so just let the slow cooker work its magic, you will not be disappointed.

If the gravy is not as thick as you like it once the beef and veggies are cooked, you have 2 options:

• you can remove the beef and veggies from the crockpot, and add more cornflour mixed with water to the liquid in the slow cooker and cook the gravy it for a further 20 minutes or until it's thicker
• you can transfer the liquid to a pan set over a medium heat on the stove top, add 1-2 tablespoons of cornflour mixed with water to it, and simmer it until it thickens
