62Granny the basket measures just under 10 inches across in both directions, it’s just under 4 inches in height. So, no, I doubt you’d get a medium chicken in it.
I live alone, plus I have very little work surface or cupboard space hence the smallish size of this suited me. In fact, tbh, it’s bigger than I expected it to be. And tbh again, it was the price that attracted me, if it turns out that I don’t get much use out of it, it’ll go to my daughter who has masses of both work surfaces and cupboard space in her kitchen.
And, tbh, I’m hoping it might help me lose a bit of weight - I often cook “one tray meals” (protein/carbs/veg all together), the plan being that I eat half and either freeze the other half or eat it the next day. But invariably I end up eating the lot over the course of the evening.
