How to Thicken Beef Stew?

You can thicken beef stew easily by taking a little cornstarch and making a paste with a little water and liquid from the stew, then adding it slowly to the stew while stirring. As the liquid mixes with the strew and simmers, the sauce will thicken. It will also thicken a little more after you cool the stew down a little. You can also use the same method with flour.
