How to Make Caramelized Onion and Cheese Steak Sandwich

Caramelize the Onions

In a pan over medium-low heat, melt butter and cook the sliced onions slowly, stirring occasionally, until they turn golden brown and sweet (about 20 minutes).

Cook the Steak

Heat oil in a skillet over medium-high heat. Add the thinly sliced steak, season with salt, pepper, and Worcestershire sauce, and cook until browned.

Melt the Cheese

Place slices of cheese over the cooked steak in the pan, cover with a lid for 1-2 minutes, and let it melt into perfection.

Toast the Bread

Lightly butter the hoagie rolls and toast them in a pan until golden and crisp.

Assemble the Sandwich

Layer the caramelized onions and cheesy steak onto the toasted bread. Add any extra toppings, and get ready to dig in!

Speed Up the Onions

Short on time? Add a pinch of sugar or a splash of balsamic vinegar to speed up caramelization.

Mush It Up

Love mushrooms? Sauté some with the onions for an even richer, steakhouse-style sandwich.

Cheese It Your Way

Provolone is classic, but mozzarella, cheddar, Swiss, or pepper jack work beautifully, too.

Make It Spicy

Add a dash of hot sauce, sliced jalapeños, or crushed red pepper flakes for extra heat.

Storage Tips

Store leftovers in an airtight container and reheat the steak gently in a skillet to keep it juicy.
