Since this roast is so amazingly delicious, I always assumed that it's not something that I would want to tackle at home. I thought it would be too complex. But as it turns out, it's very easy to make this recipe at home in your oven. This is especially true if you have a meat thermometer to help ensure you don't overcook (or undercook) the meat. It's best to cook it to medium-rare (135°F). Having said that, ribeye is marbled and juicy enough that it should taste good even when you cook it to medium doneness (145°F), as recommended by the USDA. Although that's not my personal preference.
