Ingredients
  

Main Ingredients

  • 1 ribeye steak about 8 oz, thinly sliced
  • 2 hoagie rolls toasted
  • 4 slices provolone cheese

Caramelized Onions

  • 1 large onion thinly sliced
  • 1 tbsp olive oil
  • 1 tsp butter

Horseradish Sauce

  • 3 tbsp sour cream
  • 1 tbsp prepared horseradish
  • 1 tsp Dijon mustard
  • salt and pepper to taste

Instructions
 

  • Start by caramelizing the onions. Heat oil and butter in a skillet over medium heat. Add sliced onions and cook for 10–15 minutes until golden and soft. Set aside.
  • While onions cook, mix sour cream, horseradish, and Dijon mustard in a small bowl. Add salt and pepper to taste. Set aside.
  • Season ribeye slices with salt and pepper. Sear in a hot skillet for 2–3 minutes until browned but still tender.
  • Split hoagie rolls and toast if desired. Layer steak, caramelized onions, provolone slices, and a generous spoonful of horseradish sauce inside each roll.
  • Serve warm with chips, fries, or a green salad. Enjoy!

Notes

For extra flavor, grill the steak instead of pan-searing. You can also swap provolone for cheddar or Swiss.
