Swapping a stainless steel pan for a heavy cast iron skillet alters the crust formation entirely because cast iron retains thermal energy much more efficiently. When searing thick cuts of meat at high temperatures, the metal must not drop significantly in temperature upon contact. Preheat the skillet for at least five minutes until a drop of water dances and evaporates instantly. Salting the bare bottom of the skillet directly draws surface moisture away from the meat instantly, facilitating rapid Maillard browning without requiring excess oil.
Spinach releases a high volume of water intracellularly upon heating, turning a dry sauté into a boil if the pan is overcrowded. Using a wide skillet ensures maximum evaporation surface area so the leaves wilt uniformly within 90 seconds. Fresh spinach retains cellular structure and structural rigidity that frozen varieties lack, yielding a distinct textural contrast against the tender beef. Squeeze thawed frozen spinach rigorously to extract excess liquid if fresh greens are unavailable, though the resulting mouthfeel will be noticeably softer.
Butter contains milk solids that burn quickly at high smoke points, meaning the spinach pan must be kept at a moderate medium heat separate from the steak. Turn the butterflied steak frequently every 45 seconds to ensure even internal heat penetration without overcooking the exterior edges. Remove the meat from the heat immediately when the center reaches an internal temperature of 130 degrees Fahrenheit for medium-rare doneness. Rest the protein for five minutes on a warm plate to allow redistributed juices to settle before serving.
