Ingredients
Scale
For the Sandwich:
- 1 lb steak (ribeye, sirloin, or flank)
- 4 hoagie rolls or baguettes, split
- 2 cups mixed greens (optional)
- 4 slices provolone or Swiss cheese
For the Caramelized Onions:
- 2 large yellow onions, thinly sliced
- 2 tablespoons butter
- 1 tablespoon olive oil
- 1 teaspoon sugar (optional)
- ½ teaspoon salt
For the Garlic Aioli:
- ½ cup mayonnaise
- 1 clove garlic, minced
- 1 teaspoon lemon juice
- ¼ teaspoon black pepper
Instructions
- Prepare the Steak:
- Season the steak with salt and black pepper.
- Heat a grill or skillet over medium-high heat.
- Cook the steak for 3–4 minutes per side for medium-rare, or adjust to your preferred doneness.
- Let the steak rest for 5 minutes, then slice thinly against the grain.
- Caramelize the Onions:
- Heat butter and olive oil in a skillet over medium heat.
- Add sliced onions and cook, stirring frequently, for 15–20 minutes until golden brown and caramelized.
- Add sugar and salt for enhanced sweetness, if desired.
- Make the Garlic Aioli:
- In a small bowl, mix mayonnaise, minced garlic, lemon juice, and black pepper.
- Set aside until ready to assemble.
- Assemble the Sandwich:
- Lightly toast the hoagie rolls or baguettes.
- Spread garlic aioli on both sides of each roll.
- Layer mixed greens (if using), sliced steak, caramelized onions, and a slice of cheese.
- Melt the Cheese (Optional):
- Place the assembled sandwiches in a preheated oven or under a broiler for 1–2 minutes, until the cheese is melted.
- Serve:
- Serve immediately with fries, a crisp salad, or roasted vegetables.
Notes
- For extra tenderness, let the steak rest before slicing and cut it against the grain.
- For deeper flavor, cook the onions low and slow until they are fully caramelized.
- Customize your sandwich by adding roasted peppers, avocado, or swapping cheese for cheddar or blue cheese.
