Ingredients
- 12 to 14 oz steak ribeye or sirloin
- 1 tablespoon olive oil
- ½ teaspoon kosher salt
- ½ teaspoon black pepper
- 1 small onion thinly sliced
- 1 cup sliced cremini or button mushrooms optional but great
- 1 tablespoon butter
- 2 to 3 slices provolone Swiss, or white cheddar
- 2 long rolls or 3 crusty sandwich buns split
- 2 tablespoons mayonnaise
- 1 teaspoon Dijon mustard
- Optional add-ons: arugula pickled peppers, roasted red peppers
For Marinade
- 1 tablespoon olive oil
- 1 tablespoon soy sauce
- 1 teaspoon balsamic vinegar
- 1 teaspoon Worcestershire
- 1 small garlic clove minced
- Marinate 20 to 45 minutes, then pat dry before searing.
Instructions
- Sear the steak:Heat a cast iron skillet over medium-high until very hot. Pat steak dry. Rub with olive oil, salt, and pepper. Sear 2 to 4 minutes per side, depending on thickness, until it reaches your preferred doneness.For tenderness with a blush, cook to about 125 to 130°F for medium rare. For food safety guidance, the USDA recommends 145°F with a 3 minute rest for whole cuts.
- Rest and slice: Transfer steak to a board. Rest 5 to 10 minutes. Slice thinly against the grain.
- Cook onions and mushrooms: In the same pan, lower heat to medium. Add butter, then onions and a pinch of salt. Cook until golden and soft, about 6 to 8 minutes. Add mushrooms and cook 3 to 4 minutes more.
- Toast the bread: Split rolls. Toast cut sides briefly in the hot pan for flavor.
- Build: Stir mayo and Dijon together. Spread on rolls. Pile on sliced steak, then onions and mushrooms. Top with cheese. Cover the pan 30 to 60 seconds to help the cheese melt, or slide under a broiler briefly.

Notes
- For extra flavor, brush rolls with garlic butter before toasting.
- Swap provolone for pepper jack if you like spice.
- Use leftover grilled steak for a quicker version.
