Any heat proof container that fits inside should work. Look for something that's oven safe. The recipe specifies a 4c (1qt) container.
I don't know which ones would fit well in the Instant Pot (on my to-do list) but you should be able to measure the diameter & height of the inside of the pot, then look at the specs to find one.
I use one of these to transport and microwave it, and I've never had an issue.
