I make mine in the Instant Pot, 2 hours, high pressure. I save all the garlic and onion ends I cut off, carrot or celery chunks too, in a large ziploc bag in the freezer. Check out this list of veg to use for vegetable broth as a guide for veg to put in bone broth.

I use bone broth to cook rice and as a soup base. I also use it to make any cream soup I need for a recipe, as I can thicken it with cornstarch, instead of flour. I haven't found a canned cream soup that doesn't have flour in it.
