Step 1

Season roast generously with kosher salt. Cover loosely with plastic wrap and refrigerate overnight.

Step 2

Remove the roast from the refrigerator and allow it to come to room temperature and preheat the oven to 200 degrees F.

Step 3

Mix the butter, rosemary, thyme, seasoning and black pepper together in a small bowl. Slather the butter mixture over roast and place roast in a large roasting pan.

Step 4

Transfer the roast to a preheated oven and roast until the internal temperature reaches 115 degrees F for medium-rare, about 3 1/2-4 hours. Remove from the oven and tent with aluminum foil; allow to rest, about 20 minutes.

Step 5

Meanwhile, heat a large cast iron skillet over high heat. Carefully transfer the roast into the cast iron once hot and sear on all sides for 1-2 minutes until there is a nice sear.

Step 6

Remove from the cast iron skillet and let rest for another 3-5 minutes. Remove the ribs and slice into 1/2 inch thick pieces and serve.
