Transfer to a cutting board and let it rest for 5–10 minutes.

💡 Chef’s Tips
Slice the steak against the grain for maximum tenderness.
Don’t rush the onions—slow caramelization develops their natural sweetness.
Let the steak rest before slicing to retain its juices.
Toasting the bread prevents it from becoming soggy.
🧊 Storage
Refrigerator: Store steak and onions separately in airtight containers for up to 3 days.
Reheating: Warm the steak gently in a skillet and assemble the sandwiches fresh for the best texture.
