Step 1

Preheat the oven to 450 degrees F.

Step 2

Add the butter to a small cast-iron skillet that is just slightly bigger than the steaks on high heat.

Step 3

Season the steaks all over with the salt and pepper.

Step 4

Sear the steaks on each side until browned, about 3 minutes each.

Step 5

Carefully place the seared steaks, still in the skillet, into the oven and cook until a thermometer inserted into the center reaches the desired doneness, 125 degrees F and about 4 minutes for rare, 140 degrees F and about 5-6 minutes for medium, and 160 degrees F and about 7-10 minutes for well done.

Step 6

Transfer the cooked steaks from the oven and place them on a plate covered with foil. Allow the steaks to rest for 10 minutes.

Step 7

Serve.
