Ingredients
170 g ribeye or sirloin steak
2 slices provolone cheese
2 slices mozzarella cheese
1 small yellow onion thinly sliced
2 tablespoons unsalted butter divided
4 slices thick-cut sourdough bread
0.25 teaspoon salt
0.25 teaspoon black pepper
1 small garlic clove optional
Instructions
1. Season the steak with salt and pepper on both sides.
2. Heat a skillet over medium-high heat and sear the steak for 3-4 minutes per side until medium-rare. Let it rest for 5 minutes, then slice thinly against the grain.
3. Reduce skillet heat to medium. Add 1 tablespoon butter and the sliced onion. Cook for 15-20 minutes, stirring occasionally, until onions are caramelized and golden.
4. Butter one side of each bread slice. On the unbuttered side, layer 1 slice provolone, sliced steak, caramelized onions, 1 slice mozzarella, and top with a second bread slice (buttered side out).
5. Wipe skillet clean and place over medium heat. Grill each sandwich for 3-4 minutes per side until the bread is golden and the cheese has melted.
6. Let rest for 1 minute before slicing. Serve hot.
Notes
Use a cast iron skillet for best sear and crisp crust.
Don’t rush the onions—caramelizing takes time for full flavor.
Let the sandwich rest before slicing to avoid losing melty cheese.
