Instructions

Caramelize the onions: Heat 1 tablespoon of olive oil and butter in a large skillet over medium heat. Add the sliced onions and season with a pinch of salt. Cook, stirring occasionally, for 15-20 minutes until the onions are golden brown and caramelized. Stir in the minced garlic and cook for an additional minute. For enhanced flavor, add balsamic vinegar and thyme, then remove the onions from the skillet and set aside.
Cook the steak: Using 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 3-4 minutes, stirring occasionally, until browned and cooked to your desired doneness.
Assemble the sandwich: Lightly toast the hoagie rolls in the skillet or oven. If desired, spread mayonnaise on the rolls. Layer the cooked steak onto the bottom half of each roll, then top with a generous portion of the caramelized onions. Place a slice of provolone cheese over the onions.
Melt the cheese: Place the assembled sandwich halves under a broiler or cover them in the hot skillet with a lid for 1-2 minutes until the cheese is fully melted and bubbly.
Serve: Close the sandwiches and serve them immediately to enjoy the combined rich flavors of caramelized onions, juicy steak, and melted cheese.

Notes

Use ribeye for a more tender and flavorful sandwich, or sirloin for a leaner option.
Balsamic vinegar and thyme are optional but add a great depth of flavor to the caramelized onions.
Toasting the rolls enhances texture and prevents sogginess from the steak and onions.
You can substitute provolone cheese with American cheese or mozzarella for different melty cheese textures.
Adjust the cooking time of steak based on how well done you prefer it.
