Bring the rib eye steak to room temperature – Let the rib eye steak rest on a plate for 15 minutes. Then, wipe off the moisture and liberally apply the salt and pepper to both sides.
Rinse and oil the cast iron skillet – Rinse the skillet with warm water and wipe out with paper towels. Pour one tablespoon of olive oil into the skillet, and with a paper towel, thoroughly coat the entire inside surface of the skillet with the olive oil.
Slowly heat up the cast iron skillet – Place your skillet on a stovetop burner set to low for 15 minutes. When the handle is hot to the touch, the skillet is ready to cook with.
Turn the burner up to medium-high – Turn the burner up to medium-high for 2 minutes until the olive oil starts to shimmer and smoke slightly.
Place the rib eye steak in the cast iron skillet – Drizzle a little more olive oil onto the cast iron skillet, place the rib eye steak in the skillet, and cook for 2 minutes. Lift the rib eye steak up and add another drizzle of olive oil, then flip and cook for another two minutes. Very important: do not move the steak around after it hits the pan! This is what creates a nice sear.
Add the butter and thyme to the pan and rib eye steak – With a butter knife, add the butter to the top of the steak and the cast iron skillet. As the butter melts, using a tablespoon, baste the steak with the butter 4 or 5 times. Flip the steak over, and baste with the butter again.
A meat thermometer inserted in the thickest part of the rib eye steak should read roughly 130 degrees for a medium rare steak.
