Heat oil in a large pan over HIGH heat. Brown beef and onion (You may need to do this in batches) then add to slow cooker with the potato.
Add coconut milk and recipe base to the slow cooker and stir through. Cover and cook for 4 hours on HIGH or 8 hours on LOW (Keep covered during cooking. Cooking times may vary between slow cooker models, we used a 5.5 L appliance).
Stir through chopped peanuts and serve with rice and coriander.
Recipe Tip
NO slow cooker, NO problem, place prepared casserole in an oven proof dish, cover and cook at 160°C (140°C fan-forced) for 3 hrs or until tender.
