Cast-Iron Skillet Ribeyes with Mushroom Pan Sauce

I grew up on grilled steaks, and even to this day when I go home to visit my parents, my dad insists on firing up the grill for our steak dinners. I love the flavor grilling creates, but when I tried a perfectly seared cast-iron skillet ribeye, I knew I would never even bother learning how to properly grill one. Once you cook a steak in a cast-iron skillet, you’ll never do it any other way ever again.
