Best Steak Sandwich

Step 1

Make the aioli: With a mortar and pestle, mash garlic with salt until a paste forms. Transfer paste to a small bowl and whisk in olive oil, mayonnaise, and lemon zest, then season with pepper.

Step 2

Make the steak: Brush steak with oil and season with salt and pepper. In a cast-iron pan over medium-high heat, sear both sides. Cook 3 minutes per side to the desired internal temperature and remove from heat. Let steak rest 15 minutes before slicing. Slice against the grain in 2" sections.
