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
- Prepare the herb butter:
In a small bowl, mix softened butter, crushed garlic, and diced dill until smooth and well combined. Set aside. - Slice the steak:
Slice steak into thin strips. For easier slicing, place the steak in the freezer for 10–15 minutes before cutting. - 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. - 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. - Assemble the sandwich:
Slice the baguette lengthwise. Spread herb butter generously on both sides. Layer steak, sautéed onions, and Havarti cheese on top. - 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. - 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.
