If time allows, brown the pork chops on both sides in a frying pan over medium-high heat. This adds extra flavour but can be skipped if needed.
Pour the ½ cup water into the pan and scrape up any browned bits from the bottom.
Add the potatoes, onions, garlic, onion powder, Worcestershire sauce, sage, thyme, stock, and deglazing liquid to the slow cooker.
Nestle the pork chops on top.
Cook on LOW for 5–6 hours or HIGH for 2–3 hours, until the pork is cooked through and the potatoes are tender.
Remove the pork chops and cover loosely with foil.
Mix the corn flour and water together until smooth, then stir into the slow cooker. For a thicker sauce, add an extra tablespoon of corn flour mixed with water.
Stir through the cream cheese and cream until smooth and creamy.
Return the pork chops to the slow cooker and coat in the sauce.
Serve with the potatoes and plenty of the creamy sauce spooned over the top.
