I like to cook my Ox Tails longer for better flavor. I do a pre-soak with my oxtails. I soak them in beer and a touch of apple cider vinegar for about 30 minutes. ... I let them cook on medium until they are ready to fall off of the bone.

How long do you soak oxtails?

Place thawed oxtails in a large bowl and cover with cool water. Let soak for 30 minutes. Drain the oxtails.

How do you tenderize oxtails?

Just bring your oxtails to a boil in a heavy bottom pot, that retains heat well, then reduce heat to MED and simmer with lid on, until the oxtails are tender. This will take 2 to 3 hours. But the results will be well worth the wait.
