- prep
Pat the steaks dry and season.

TIPDry steaks sear better — moisture is the enemy of a good crust. - grill · ~6 min
Sear the steaks.
1.Heat olive oil in a large cast iron skillet over high heat until shimmering and just starting to smoke.2.Carefully lay steaks in the pan away from you. Sear without moving for 3 minutes until a deep brown crust forms.3.Flip and cook another 2-3 minutes for medium-rare (internal temp 130-135°F / 54-57°C).4.Transfer steaks to a cutting board, tent loosely with foil, and rest.TIPDon't crowd the pan — cook in batches if needed. Overcrowding steams the meat instead of searing. - saute · ~2 min
Wilt the spinach with garlic.
1.Reduce heat to medium. Add sliced garlic to the same pan and sauté until fragrant (30 seconds).2.Add spinach in handfuls, tossing with tongs until just wilted (1-2 minutes).3.Season with a pinch of salt and squeeze in juice of half a lemon. Toss to combine.TIPSpinach wilts fast — pull it off the heat the moment it collapses to keep it vibrant green. - assemble
Slice steak and plate with spinach.
Slice rested steaks against the grain into thin strips. Divide spinach among plates, top with sliced steak, and serve with lemon wedges on the side.
TIPSlicing against the grain shortens the muscle fibers, making every bite tender.
What to keep in mind.
5 tips from the recipe — small details that make a real difference to the final dish.
- 1Rest the steak for 5 minutes before slicing to allow juices to redistribute.
- 2Use a cast iron skillet for the best crust and even heat distribution.
- 3Don't move the steak while searing; letting it sit undisturbed builds a deep crust.
- 4Add spinach in handfuls to prevent the pan from cooling down too quickly.
- 5Slice against the grain at a slight angle for maximum tenderness.
