How to Make Grilled Steak Sandwiches With Melted Onion Sauce

  1. In a large bowl, combine 1 tbsp olive oil, 1 tsp salt, 1/2 tsp black pepper, and 1/2 tsp garlic powder. Add 1 lb steak (sirloin, ribeye, or your favorite cut) and marinate for at least 30 minutes.
  2. While the steak marinates, prepare the onion sauce: melt 2 tbsp butter in a large skillet over medium heat. Add 2 large onions, thinly sliced, and cook until softened and caramelized, about 20-25 minutes, stirring occasionally. Season with 1/4 tsp salt and 1/4 tsp sugar.
  3. Preheat grill to medium-high heat. Grill the steak for 4-6 minutes per side, or to desired doneness. Let rest for 5 minutes before slicing thinly against the grain.
  4. Spread the caramelized onion sauce generously on toasted rolls. Top with sliced steak, and any desired additional toppings (e.g., cheese, lettuce, tomato).
  5. Serve immediately and enjoy!
