Instructions

Heat the skillet: Place olive oil in a skillet over medium-high heat to warm up for searing the steak.
Season and sear the steak: Season the thinly sliced steak evenly with salt and black pepper. Add it to the hot skillet and sear each side for 1–2 minutes until browned but still tender inside.
Add butter and garlic: Reduce the heat to medium, then add the unsalted butter and minced garlic to the skillet. Cook while stirring for about a minute to coat the steak with fragrant garlic butter.
Incorporate Worcestershire sauce: Stir in the Worcestershire sauce to the steak mixture, then remove the skillet from heat to preserve the tender steak’s texture.
Preheat for melting: Begin heating a clean skillet or panini press to prepare for melting the croissant sandwiches.
Assemble the croissant melts: On the bottom half of each croissant, layer slices of Brie cheese, the garlic butter steak, thinly sliced red onion, and arugula or baby spinach if desired. Top with the other croissant half.
Cook the melts: Place the assembled croissants in the preheated skillet or panini press. Cook for 3–4 minutes, pressing gently, until the Brie melts and the croissants become golden brown and crisp.
Serve hot: Remove the melts from heat and serve immediately for the best flavor and texture.

Notes

For extra flavor and crunch, toast the croissant halves lightly before assembling the sandwich.
Substitute Brie cheese with fontina or provolone for a different but equally delicious melt.
This sandwich pairs wonderfully with a light salad or crispy fries for a complete meal.
