    Cooking a roast in your slow cooker

    Roast meat cooked in your slow cooker is rather like cooking a pot roast since you cook your meat in a covered pot and can also add in vegetables beneath the meat if you like. 

    You still get great results with slow cooker roasts even without the oven!

    Even though traditionally you would cook your roast meat for your roast dinner in the oven, it is worth giving the slow cooker method a go.

    You can basically cook any joint of meat (called a roast in the USA) that you would buy in the supermarket for roasting in your slow cooker, provided it fits your pot that is.

    I tend to use my larger slow cooker for the roast meat, which is a 5.7 litre slow cooker. Then the smaller ones are free to be used for side dishes or dessert!

    I prefer to cook my vegetables on the side or in another slow cooker rather than including them in the slow cooker with the roast beef or chicken.

    If you cook for example carrots and potatoes under a piece of beef then they all taste the same by the end of cooking.

    This is because they cook in the fatty juices of the meat.

    It works in terms of they will cook, but you’ll get better results cooking them separately in my view. 

    Potatoes and carrots will be soft and not as good as crispy roast potatoes and carrots boiled in water.

    Top tips 

    Just remember that you don’t need to use as much liquid for a slow cooker pot roast because when cooking in a slow cooker liquid won’t evaporate off.

    Also plenty of juices will come out of the meat as it cooks. In some of these recipes I don’t use any stock for cooking at all (pork, lamb and so on) whereas for beef brisket it is best to add a small amount of beef stock.

    Remember to add flavour by using your preferred meat stock (broth), if you have homemade stock even better. Also use herbs and spices to enhance the flavour of the meat.

    Recipes

    Here I’ve put together my favourite slow cooker roast dinner recipes so you can use this collection for whichever meat you want to base your roast meal on, whether slow cooker roast beef, pork, lamb, turkey crown, gammon or whole chicken.

    Slow cooker lamb with rosemary, garlic and mint sauce

    Slow cooker roast beef

    I always find that a cut of beef selected for slow cooking works best, and so I normally use brisket when making slow cooker roast beef, and cook it on a bed of onions.

    It becomes so tender after slow cooking and makes a delicious gravy too.

    Alternatively you can also cook the beef roasting joints which tend to be silverside or topside with great results in the slow cooker – for these I like to cook them in a little beef stock with red wine, for 6 hours on low or 3 hours on high.

    Slow cooker pork

    Roast pork with fresh sage leaves and onion is a classic flavour combination and works so well in the slow cooker too. Cook your pork joint without any added liquid for best results.

    For this recipe I cook the meat in a hot oven briefly after slow cooking to get really crispy crackling.

    Slow cooker lamb

    Whether you are cooking a shoulder of lamb, a half leg or a whole leg of lamb, they all work brilliantly in the slow cooker.

    Slow cooker roast lamb with garlic and rosemary, on a bed of red onions and with added mint sauce if you like, will make your kitchen smell delicious as it cooks away.

    An everyday unsmoked gammon joint becomes a delicious roast gammon in this simple slow cooker gammon recipe with apple juice and maple syrup drizzled over before roasting briefly in a hot oven.

    Slow cooker turkey crown

    Turkey breast or turkey crown is usually chosen at Easter or Christmas but of course you can enjoy them all year round if you can pick one up!

    Here turkey breast on the bone (a turkey crown) is cooked with a delicious spice rub. You can also cook a whole chicken in the slow cooker in the same way.

    Slow cooker roast chicken

    I tend to use a medium chicken (1.3 kg / 3 lb) and then cook it on high for 3 hours. At the end of slow cooking I lift the chicken into an oven tray and roast for about 10 minutes to crisp the skin.
