Slow Cooker Gammon being sliced on a board

Slow Cooker Gammon

  • Author: caroline
  • Total Time: 4 hours 10 minutes
  • Yield: 4 1x


Transform an ordinary joint of gammon into something truly special! This slow cooker gammon is cooked in sweet apple juice and then basted with a honey and mustard glaze. Delicious!

Allow around 175-200g uncooked gammon per person for a generous portion – but I strongly suggest you make enough for leftovers! 


  • gammon joint – I used 0.75kg (1.6lb) but you can use a larger one and slightly adjust the cooking times (see notes)
  • 1 large onion, sliced into 810 pieces
  • 500ml / 2 cups apple juice (increase to up to 1l / 4 cups if you are using a larger piece of gammon)
  • 1 tbsp wholegrain mustard
  • 1 tbsp honey


  1. Place the onion slices on the bottom of the slow cooker and then sit the gammon on top, fat side up. 
  2. Pour the apple juice around the gammon and then cook on high for 3-4 hours or on low for 7-8 hours. 
  3. Mix together the honey and mustard and place in the fridge until needed. 
  4. When cooked, remove the gammon from the slow cooker and heat the oven to 200C/400F. Remove the thick skin from the top fo the fat, leaving behind a thin layer of fat. Score the top of the fat in a cross-hatch pattern and then brush over the honey and mustard glaze. 
  5. Place in the oven for 10-15 minutes until the glaze has thickened and browned. 
  6. Leave to rest for at least 20 minutes before carving and serving. 


  1. You can use either smoked or unsmoked gammon, depending on your preference. 
  2. If you are using a larger joint (over 1kg/2.2lb) then increase the cooking time for high by 1 hour and the cooking time for low by 2 hours
  3. You can use cider, stock, or even coke instead of the apple juice to give a slightly different taste profile.
