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 onions become golden brown and caramelized. Stir in minced garlic and cook for an additional minute. Optionally add balsamic vinegar and thyme to enhance the flavor. 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 heat to medium-high. Season the steak slices with salt and pepper. Cook the steak for 3-4 minutes, stirring occasionally, until browned and cooked to your preferred doneness.
Assemble the sandwich: Lightly toast the hoagie rolls in the skillet or oven. Spread mayonnaise on the rolls if desired. Layer the cooked steak on the bottom half of each roll, followed by a generous portion of caramelized onions. Place a slice of provolone cheese on top.
Melt the cheese: Place the sandwich halves under a broiler or cover the skillet with a lid and heat for 1-2 minutes until the cheese melts and becomes bubbly.
Serve: Close the sandwiches and serve immediately while warm, enjoying the rich combination of caramelized onions, juicy steak, and melted cheese.

Notes

Using ribeye provides a richer flavor, but sirloin is a leaner, budget-friendly alternative.
If you prefer less sweetness, omit the balsamic vinegar from the caramelized onions.
To make it spicier, add sliced jalapeños or a dash of hot sauce when assembling.
For a crispier bread, toast the rolls a bit longer before assembling.
Leftover steak and onions can be refrigerated for up to 2 days and used for sandwiches or salads.
