What cut of steak works best for this sandwich?
New York strip steak is ideal—it's tender, flavorful, and slices cleanly. Ribeye or flank steak are solid alternatives.
Can I make the chimichurri ahead of time?
Yes. Combine the cilantro, parsley, garlic, oregano, and chilies up to 4 hours ahead. Add oil just before serving to keep it fresh.
How do I keep the crispy shallots crispy until serving?
Fry them no more than 30 minutes before assembly. Store in a paper towel-lined container at room temperature; they'll stay crisp for about 2 hours.
What temperature should the steak be cooked to?
Medium-rare (130–135°F internal) is recommended for tenderness and flavor with this sandwich's fresh, acidic toppings.
Can I substitute the baguette?
Yes—ciabatta, sourdough, or focaccia work well. Avoid soft breads that won't hold up to the fillings and sauce.
