Take the ribeye out of the refrigerator and let it rest at room temperature for about 1½ hours. Allowing it to warm up slightly ensures more even cooking.
In a small bowl, mix the softened butter with rosemary, thyme, paprika, salt, and black pepper until well combined.
Rub the seasoned butter mixture all over the roast, coating every side.
Set the roast on a rack inside a roasting pan lined with foil. Insert a meat thermometer into the thickest part of the roast, making sure it doesn’t touch bone or large pockets of fat.
Roast, uncovered, following the cooking time guide for your preferred level of doneness (times may vary depending on weight and whether the roast is bone-in or boneless).
Once done, remove the roast from the oven and loosely cover with foil. Let it rest for 20 minutes before slicing—the internal temperature will continue to rise by 5–10 degrees as it rests.
