Ingredients

Scale

Herb Butter

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

Steak Sandwich

  • 1 tablespoon oil
  • 1 pound steak (ribeye, sirloin, flank, or skirt)
  • 1 tablespoon salt (adjust to taste)
  • 1 large yellow onion
  • 4 slices Havarti cheese
  • 1 baguette

Instructions

  1. Prepare the herb butter:
    In a small bowl, mix softened butter, crushed garlic, and diced dill until smooth and well combined. Set aside.
  2. Slice the steak:
    Slice steak into thin strips. For easier slicing, place the steak in the freezer for 10–15 minutes before cutting.
  3. Cook the steak:
    Heat oil in a skillet over high heat. Add steak strips and season generously with salt. Cook until just golden brown, about 2–4 minutes. Remove from skillet and set aside.
  4. Sauté the onions:
    Slice onion into half rings. Using the same skillet, cook onions over medium heat until golden brown and softened. Remove from heat.
  5. Assemble the sandwich:
    Slice the baguette lengthwise. Spread herb butter generously on both sides. Layer steak, sautéed onions, and Havarti cheese on top.
  6. Broil:
    Place the open-faced sandwich under the broiler for about 2 minutes, or until cheese is melted and bubbly. Watch closely to prevent burning.
  7. Serve:
    Close the sandwich, slice, and serve immediately while warm.

Notes

  • For the most tender bites, slice steak against the grain.
  • Do not overcrowd the skillet when cooking steak; cook in batches if needed.
  • Substitute Havarti with provolone, Swiss, or mozzarella if preferred.
  • Herb butter can be prepared up to 3 days in advance and stored in the refrigerator.
  • Leftovers can be reheated in the oven or air fryer for best texture.
