Ingredients

Units Scale

Herb Butter

  • 1/2 cup unsalted butter, softened
  • 1 tbsp fresh dill, diced
  • 3 garlic cloves, crushed

Steak Sandwich

  • 1 tbsp oil (vegetable or olive oil)
  • 1 lb steak (such as ribeye or sirloin)
  • 1 tbsp salt, adjust to taste
  • 1 large yellow onion, sliced into half rings
  • 4 slices Havarti cheese
  • 1 baguette, sliced lengthwise

Instructions

  1. Prepare Herb Butter: In a small bowl, combine the softened butter with crushed garlic cloves and diced fresh dill. Mix thoroughly until all ingredients are evenly incorporated to form a smooth herb butter spread. Set aside.
  2. Slice Steak: Freeze the steak for a few minutes to firm it up, making it easier to slice. Then, cut the steak into thin strips suitable for sandwich fillings.
  3. Cook Steak: Preheat a skillet over high heat and add 1 tablespoon of oil. Once hot, add the steak strips and season generously with salt. Cook the steak quickly until just golden brown on the outside but still tender inside. Remove the steak from the skillet and set aside.
  4. Sauté Onions: In the same skillet used for the steak, add the sliced onions. Sauté them over medium heat until they become golden brown and caramelized, stirring occasionally. Remove from heat and set aside.
  5. Assemble Sandwich: Slice the baguette lengthwise and spread the prepared herb butter evenly on both sides of the bread. Layer the cooked steak strips over the buttered bread, followed by the sautéed caramelized onions, and then top with slices of Havarti cheese.
  6. Broil Sandwich: Keep the sandwich open-faced and place it under a broiler for about 2 minutes, or until the cheese melts and becomes bubbly. Keep a close eye to prevent burning.
  7. Serve: Remove the sandwich from the broiler and serve immediately while it is still warm and the cheese is melted for the best flavor and texture experience.

Notes

  • Freezing the steak briefly before slicing helps achieve thin, even strips that cook quickly and evenly.
  • You can substitute Havarti cheese with other meltable cheeses like provolone or mozzarella if preferred.
  • Adjust salt and seasoning to taste depending on the cut of steak used and personal preference.
  • For extra flavor, consider adding a spread of mustard or horseradish sauce before layering the steak.
  • Broiling times may vary depending on your oven; watch carefully to avoid overcooking the bread or burning the cheese.
