Use our 100% grass-fed and finished beef arm roast for a pot roast or cut it up for stew meat. It has enough tallow to easily keep the meat moist and tender. You can use a slow cooker or simply wrap your seasoned roast in foil with the seam at the top to hold in juices and cook in the oven at 225 to 250 for 5 or 6 hours. This is just a butcher’s blade away from the shoulder roast the difference between the two is that the arm roast has a round bone in it and is slightly more tender.
