  • 8 pork sausages
  • 500 mls tomato passata
  • 1 large garlic clove minced
  • 1 large rosemary sprig
  • 1 medium onion chopped into half moons
  • ½ tsp ground black pepper

Recipe Notes

  • You can of course add extra vegetables. I am thinking chunks of butternut squash or swede, button mushrooms (put in a couple of hours before the end of cooking) or carrots. The vegetable aisle is your oyster. This is just my own personal preference but it is only a template. Empty out your vegetable drawer baby to suit.
  • The herbs too can be replaced to suit your tastes. Thyme is an obvious one to add due to it's great compatibility with pork but you could crush some fennel seeds in there or add some basil or oregano. Jamie would be proud.
  • I sometimes make this the day before, allow to cool and then refrigerate in the slow cooker pot. I then reheat it back in the slow cooker until it's piping hot for when I need it. I'm on fire.....
  • If you don't have balsamic vinegar in the cupboard then any standard vinegar will do.
  • Simply double up to feed 8. These servings are generous.
  • I do strongly recommend that you use sausages with a high percentage of meat in. This gives the whole thing a much better flavour and the sausages stay meaty and intact during cooking.
