The best cut of beef to use for a vegetable beef soup recipe are chuck shoulder, chuck roast, chuck-eye roast, or top chuck. Unlike other cuts, these types are cheaper, and when cooked for a prolonged period, it results in meltingly tender and flavorful chunks of beef. A great alternative with less cooking time is sirloin tips. It produces the same results and saves you some time. The downside is it’s a little more pricey.
