Ingredients List

• 2 ribeye or sirloin steaks (about 250 g each)
• Salt and freshly ground black pepper
• 1 tablespoon olive oil
• 2 tablespoons butter
• 4 sandwich rolls or ciabatta bread
• 1 large onion, thinly sliced
• ½ cup all-purpose flour
• ½ teaspoon paprika
• ½ teaspoon garlic powder
• Oil for frying
• 4 slices provolone or cheddar cheese
• 2 tablespoons mayonnaise
• 1 teaspoon Dijon mustard
• Fresh arugula or lettuce leaves

Step-by-Step Instructions

Prepare the Crispy Onions

Toss sliced onions with flour, paprika, garlic powder, and a pinch of salt. Fry in hot oil until golden brown and crisp. Drain on paper towels and set aside.

Season the Steak

Pat steaks dry and season generously with salt and freshly ground black pepper to ensure proper crust formation.

Sear the Steak

Heat olive oil and butter in a heavy skillet over high heat. Sear steaks for 3–4 minutes per side until a rich golden crust develops.

Rest the Meat

Transfer steaks to a board and rest for 5 minutes. Resting allows juices to redistribute for maximum tenderness.

Toast the Bread

Slice sandwich rolls and toast lightly in the same pan to absorb steak flavor.

Slice and Assemble

Thinly slice steak against the grain. Spread mayonnaise mixed with Dijon mustard onto bread.

Build the Sandwich

Layer sliced steak, melted cheese, crispy onions, and fresh greens onto toasted rolls.

Final Finish

Close sandwiches gently and serve immediately while warm and crisp.

Storage Instructions

For best results, assemble sandwiches just before serving.
Store cooked steak separately in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet to maintain tenderness. Crispy onions should be stored separately at room temperature in a dry container to preserve crunch.

Suggestions

• Add sautéed mushrooms for a steakhouse-inspired variation.
• Use garlic aioli instead of mayonnaise for deeper flavor.
• Brioche or pretzel buns add richness and structure.
• Include pickled jalapeños for heat and acidity balance.
• Serve with fries, coleslaw, or roasted potatoes for a complete meal.
