If you have an air fryer, use it to cook the butter beans. If not, preheat oven to 200C.
Empty the butter beans into a sieve to drain them and rinse with cold water.
Transfer to a clean tea towel, spacing them out, and allow them to dry as best as possible.
Toss the butter beans with 1 tbsp olive oil, the garlic granules and a good pinch of salt.
Cook for 12-15 minutes in an air fryer or preheated oven until golden brown and crispy - they will ‘explode’ a bit, this is what you want, and makes the edges crispier.
Enjoy straight away - they loose their crunch when stored.
