Chef John's Best Steak Sandwich Ever

Ingredients 0/13

Step 1

Heat your grill to medium-high and give the grates a quick brush with some oil to keep things from sticking. Slice the steak into six thick strips and season them well with salt and pepper. While the grill is heating, toss the mushrooms on and let them cook for about 5 to 6 minutes until they start to soften. Take off the stems and break the mushrooms apart a bit, then mix them in a bowl with a pinch of salt and pepper, a splash of sherry vinegar, and a drizzle of good olive oil. Set that aside for now.

Step 2

Grill the steaks for around 3 to 4 minutes on each side, aiming for medium rare—if you have a thermometer, you're looking for about 140°F in the center. Once they're done, let the steaks rest for 5 minutes to keep them juicy. While that’s happening, whisk together some barbecue sauce, cider vinegar, and vegetable oil to make a tangy sauce.

Step 3

To assemble, pile the grilled steak strips onto toasted hot dog buns, spread a little mayo, add some fresh arugula, halved cherry tomatoes, the marinated grilled mushrooms, and finish it off with a generous drizzle of that barbecue sauce mix. Enjoy!
