Fresh thyme (optional for garnish)
Instructions:
-
Caramelize the onions:
In a skillet, melt butter with olive oil over medium heat.
Add onions, sugar, and salt. Cook 20–25 minutes, stirring occasionally, until golden brown and soft.
Deglaze with a splash of beef broth to loosen browned bits and make them extra flavorful. -
Cook the steak:
Season steak with salt, pepper, garlic powder, and Worcestershire sauce.
Heat olive oil in a hot skillet or grill pan.
Sear steak 3–4 minutes per side for medium-rare, or to your liking.
Let rest 5 minutes, then slice thinly against the grain. -
Toast the bread:
Spread butter on sandwich rolls and toast in a skillet or under the broiler until golden. -
Assemble:
Place sliced steak on the bottom half of each roll.
Top with a generous pile of caramelized onions and 2 slices of cheese.
Broil open-faced for 1–2 minutes until cheese melts and bubbles. -
Serve:
Close the sandwich, slice in half, and sprinkle with a little fresh thyme if desired.
Serve hot with au jus or beef broth on the side for dipping — French dip style!
