This recipe is a Tex-Mex twist on roasted potatoes. Ranch dressing, taco seasoning and cheddar cheese are mixed together. Cubed potatoes are tossed with the ranch dressing mixture. Then the coated potatoes are placed in a baking dish covered with foil. Halfway through the baking, the foil is removed to help crisp the potatoes. Extra cheese is sprinkled on the finished potatoes.
