Ingredients
Scale
1 pound of flank steak or sirloin steak, thinly sliced
4 tablespoons of unsalted butter, divided
4 cloves of garlic, minced
2 large onions, thinly sliced
1 tablespoon of brown sugar
Salt and pepper, to taste
4 crusty sandwich rolls (like ciabatta or baguette)
Fresh parsley, chopped, for garnish (optional)
Cheese (optional; provolone or cheddar works beautifully)
Instructions
Begin by marinating your sliced steak in a mixture of 2 tablespoons of melted butter, minced garlic, salt, and pepper. Let it sit for 15 minutes to enhance flavor and tenderness.
In a large skillet, melt 2 tablespoons of butter over medium heat. Add the thinly sliced onions and a pinch of salt. Stir occasionally for about 10-15 minutes until they are golden brown and soft. Add the brown sugar to enhance their sweetness and caramelized flavor.
In a separate skillet over medium-high heat, cook the marinated steak for about 3-4 minutes on each side, depending on your preferred level of doneness.
Slice the sandwich rolls in half and lightly toast them if desired. Layer the steak slices and caramelized onions generously. If you're feeling indulgent, add slices of cheese on top.
Spread the remaining melted garlic butter on the top half of the bread to lock in moisture and enhance flavor. Close the sandwich and secure with toothpicks if necessary.
Cut the sandwich in half, garnish with chopped parsley if you like, and serve hot.
