Inside a plastic pot with the bottom cut off. I've had mine like that for years. I do recommend planting different varieties in separate pots.. a few of mine are mixed and some types are more thuggish than others.
I used the large black pots that my fruit trees came in.
Mine are in very large plastic pots with the bottom cut out as @Blue Onion describes above. They are then sunk into the shadier damper end of our herb bed with the top two inches of the pot sticking up above soil level (important otherwise the plant’s runners will escape and spread across the area).
Every other year in early spring we lift the pots and renew the soil/compost mix, replanting the younger parts of the roots and discarding the older central part.
It may be less trouble not to sink the pots in the ground, but they will need even more watering.
Mint is hungry ... it needs feeding. Mine get Fish, Blood & Bone in March and June.

Apple mint grows wild here throughout most of the plot. Smells lovely in the areas we mow and is easily weeded out of the beds where I don't want it.
I grow my other mints in large ceramic or plastic pots which I keep on our north facing but bright terrace so they don't fry in the heat of the day. They get all their old growth and woody sticks removed in spring and then a generous handful or two of pelleted chicken manure and a good drink. Whether in pots or in the ground it's important to keep mints apart or their distinct flavours start to merge and get confuddled.
I also grow hostas and fuchsias in pots in the same area and put my houseplants out there for summer. I have an outside tap and hose by the back door so it's easy to scatter them about and easy to water.
