Ingredients

Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large skillet over medium heat. Add 1 large thinly sliced yellow onion with 1/2 tsp salt and cook, stirring occasionally, for 15 minutes until the onions are golden brown and caramelized.
  2. Step 2: While onions cook, season 12 oz thinly sliced ribeye steak with 1 tsp salt, 1/2 tsp black pepper, and 1/4 tsp garlic powder. Heat a grill pan over medium-high heat and grill the steak slices for 2 minutes per side until just cooked through and slightly charred.
  3. Step 3: Preheat oven broiler to high. Slice 2 hoagie rolls lengthwise, brush the insides with 1 tbsp olive oil, and toast under the broiler for 1-2 minutes until golden.
  4. Step 4: Layer the grilled steak slices evenly inside each toasted hoagie roll, top with 2 slices of provolone cheese and half the caramelized onions. Place sandwiches on a baking sheet and broil for 2 minutes until cheese melts and bubbles.
  5. Step 5: Remove sandwiches from oven, let cool for 1 minute, then serve warm.
