Due to its long simmer time, beef stew has an incredible, thick texture. However, a common mistake can lead your stew to becoming too dense: adding too much flour or cornstarch.
While some recipes often call for a roux or slurry, if you make an old-fashioned beef stew with potatoes, the starch from the potatoes can act as a natural thickener.
Plus, you can lightly coat the beef in cornstarch for a better sear. The remaining powder will transfer into the stew, giving it a slightly richer texture.
