Lay out a rectangular sheet of foil on your bench

Wash and trim beans and lay them in centre of foil

Top with butter and garlic

Fold foil into a parcel around beans (bring long sides together and folded over first, then both ends folded up tight works well)

Place into slow cooker and cook on high for 45-60mins or until beans are done to your liking.

Be careful opening the foil tent as hot steam will escape when you do!
