Preheat the oven to 350°F.
Pat the rib roast dry with paper towels. Season the entire roast very well with steak seasoning and salt (as a gauge: cooking time will be about 16-22 minutes per pound depending upon the temperature you desire).
Heat 1 teaspoon of oil in a pot over medium-high heat. Sear the roast until nicely browned on all sides. Once the outside is crusty and browned well place the roast, fat side up, on a wire rack or parchment paper-lined baking sheet. Place the rosemary and garlic on top and roast in the oven until the desired temperature is reached using a thermometer (see below). Let the roast rest on a cutting board for 5-10 minutes before slicing.
In a sauce pan over low heat, add the broth, garlic, butter, and thyme. Bring to a low simmer for about 10-15 minutes until the flavor concentrates. Season with salt to taste.
Slice the roast about 1/4 - 1/2 inch thick, about 3 oz portions. Trim any excess fat around the sides if desired before serving.
Spoon a little of the flavored broth over top of the meat and serve with bread. Garnish with thyme sprigs.
