    My slow cooker roast pork with sage and onion lets you use your slow cooker for a midweek roast dinner and save time, ending up with a delicious meltingly soft joint of meat with crackling, flavoured with herbs.

    When life is busy, I can’t do without my slow cooker.

    A busy day calls for throwing a meal in the slow cooker in the morning and forgetting about it.

    Have you noticed that pork and lamb is on offer in the supermarkets right now, since everyone is buying turkey and beef I guess, and you can pick up a large joint for much less than usual? 

    I’ve been taking advantage of this and been cooking some delicious midweek roasts using the slow cooker.

    So after a few minutes of prep in the morning I can forget about dinner and get on with my day, smug in the knowledge that I already have our meal covered.

    It only takes a few minutes if that to prepare the dish. 

    And the bonus of opening the door at the end of the day to the welcoming smell of a tasty meal cooking away is just the cherry on the top.

    I can just prepare some roast potatoes and vegetables, and put the cooked pork in a hot oven to make the crackling, without having to start cooking a full meal from scratch or resorting to something quick from the freezer. 

    Once slow cooked, the meat is soft and full of flavour. A quick blast in a hot oven to create crackling is all that’s needed!

    Ingredients

    Here’s what you will need for this simple recipe (grab the quantities from the recipe card at the bottom of the page):

    • a pork crackling joint – this might be pork loin, pork shoulder or pork leg, look out for a pork joint sold as a pork crackling joint or one that makes good crackling.
    • onions
    • fresh sage leaves – to add a touch of flavour alongside the onions, for that traditional sage and onion taste. I am lucky that I have a large sage bush in the garden to use. If you don’t have fresh, then dried sage is an alternative.
    • salt and pepper to season

    How to make roast pork in your slow cooker

    Step 1. Place the pork roast joint on a bed of onions, season and and add fresh chopped sage leaves.

    Step 2. Cook on low for 8 to 10 hours.

    Step 3. To make the crackling, transfer the pork to an oven tray, pat the fat dry with kitchen towel and rub it with salt, and put it in a hot oven (220°C) for 20-30 minutes until crackling forms.

    Delicious! Do you rely on your slow cooker too for easy midweek meals?

    Ingredients

    • 1.5 to 2 kg (3.5 lb) pork crackling joint (pork roast) to serve 6-8 people
    • 2-3 brown onions
    • fresh sage leaves
    • salt and pepper to season

    Equipment

    large oval slow cooker

    Instructions
     

    • Slice the onions and place them in the base of the slow cooker. Tear the sage leaves and scatter a few in with the onions.
      2-3 brown onions, fresh sage leaves
    • Place the joint of pork on top, season and add a few more sage leaves on top.
      1.5 to 2 kg pork crackling joint, salt and pepper
    • I cook in the slow cooker for two hours on high then six hours on low, total eight hours cooking time. If all on low I would do cook for about ten hours for a large joint of pork. (Reduce the time to eight hours on low for a smaller joint.)
    • To make the crackling, transfer the pork to an oven tray, pat the fat dry with kitchen towel and rub it with salt, and put it in a hot oven (220℃ / 430℉) for 20-30 minutes.

      I’m using a boneless leg joint in my slow cooker, is that what you’ve used or is it shoulder pork ?

        Often the pork crackling joints from the shops are loin I believe, so this would be what I would normally use, but according to lovepork.co.uk you can use any roasting cut like pork loin, pork leg, pork shoulder to achieve a joint with crackling, just make sure they have a good layer of fat beneath the rind and score it well.

        Hi Paul, I don’t add any liquid at all, the meat makes lots of juices as you cook it. So you stand the meat on the onions so it isn’t sitting in all the juices. Hope that helps!

      This is definitely the time of year to make recipes that work well but take leiitle effort and slow cooking a lovely piece of pork is exactly what I did today too, tastes so good and pleases the family. Love the sage and onion with it too, perfect!
