Bistro Skirt Steak Sandwiches with Caramelized Onions and Basil-Balsamic Mayo

steps

Bistro Beef Steak Sandwiches

1. Preheat a grill or grill pan over medium-high heat. Slice buns and cook cut side down over direct heat until slightly charred and toasted.
2. Coat the skirt steak in oil and season liberally with salt and pepper. Add the steaks to the grill over direct heat and cook for 2−3 minutes on each side for medium rare/medium (depending on the thickness). Remove steaks from grill, allowing them to rest for 4−5 minutes before slicing.
3. Thinly slice the steaks on the bias and across the grain every ¼ inch or so. Pile the sliced steak high on the bottom side of the bun while generously coating the top side of the bun with the mayo and onions. Top off the sandwich and serve immediately.

Caramelized Onions

1. Add ingredients into a skillet over medium-low heat. Cook onions for 25−35 minutes, stirring often until browned and tender.

Basil-Balsamic Mayo 

1. Wisk together ingredients into a mixing bowl until thoroughly combined. Cover and keep chilled until ready to serve.
