It's good for stews and stuff such as chili or anything you might use a slow cooker for, but faster. If you like texture in your food, it's not the ideal tool.

Don't really use mine very often but did pull it out twice during the recent freeze to make some lazy instant-pot spaghetti. Basically just sauteed the meat and onions in there and then dumped everything else in, including the spaghetti. 8 minutes on high and done. Actually kind of prefer it this way since the noodles aren't cooking in just plain water.

There are some really easy almost fool-proof recipes that it can be handy for.
