Instructions

Caramelize the onions: Heat 1 tablespoon of olive oil and the butter in a large skillet over medium heat. Add the sliced onions and a pinch of salt, cooking them while stirring occasionally for 15 to 20 minutes until they become golden brown and caramelized. Stir in the minced garlic and cook for an additional minute. If using, add balsamic vinegar and thyme for enhanced flavor. Remove the onions from the skillet and set aside.
Cook the steak: In the same skillet, add the remaining tablespoon of olive oil and increase the heat to medium-high. Season the thinly sliced steak with salt and pepper. Cook the steak for about 3 to 4 minutes, stirring occasionally, until the meat is nicely browned and cooked to your preferred doneness.
Assemble the sandwich: Lightly toast the hoagie rolls either in the skillet or in the oven. Spread mayonnaise on the rolls if desired. Begin layering by placing the cooked steak on the bottom half of each roll, followed by a generous portion of caramelized onions. Add one slice of provolone cheese on top.
Melt the cheese: Place the assembled sandwich halves under a broiler or cover and heat them in a hot skillet for 1 to 2 minutes until the cheese melts and becomes bubbly.
Serve: Close the sandwiches and serve immediately to enjoy the delicious combination of savory steak, sweet caramelized onions, and melty cheese.

Notes

For a more intense flavor, use balsamic vinegar and fresh thyme in the onion caramelization step.
You may substitute provolone cheese with American cheese or your favorite melting cheese.
To make the sandwich spicier, add a few slices of jalapeño or your preferred hot sauce.
Use freshly sliced ribeye or sirloin steak for tender and juicy results.
If you prefer, omit mayonnaise or substitute with mustard or aioli.
