Steak Sandwich Horseradish (Print Version)

# Ingredients:

→ Steak Marinade

01 - 3 lbs skirt steak
02 - 6 tablespoons olive oil, split
03 - 2 tablespoons sea salt
04 - 1 tablespoon ground black pepper
05 - 2 teaspoons smoked paprika powder
06 - 2 teaspoons ground cumin
07 - 5 garlic cloves, crushed
08 - 2 teaspoons oregano, dried
09 - ½ teaspoon cayenne pepper

→ Creamy Horseradish Sauce

10 - 1¼ cups mayo
11 - 1 tablespoon prepared horseradish
12 - ½ teaspoon flaky salt
13 - ½ teaspoon freshly cracked black pepper
14 - 2 tablespoons finely chopped chives

→ Putting It Together

15 - 1 big red onion, cut into ½-inch rings
16 - 4 toasted ciabatta rolls
17 - 4 crisp red leaf lettuce pieces

# Instructions:

01 - Fire up the grill to 425°F, using cooler indirect heat. In a food processor, blitz together ¼ cup of the olive oil and spices for a 30-second blend. Coat the steak in marinade and let it chill on the counter for 20 minutes.
02 - Drizzle the onion slices with whatever olive oil’s left. Lay them on the grill over direct heat for 3 to 4 minutes, flipping as needed. If they’re browning too fast, shift to a cooler spot.
03 - Sear steaks 2 minutes on each side, then slide them to indirect heat. Cover, and cook another 5 minutes for a medium finish. Let them rest for 5 minutes and slice thinly across the grain.
04 - While the steak hangs out, stir together the mayo, horseradish, chives, salt, and pepper until it’s nice and smooth.
05 - Slather the mayo onto both sides of the warm buns. Stack on the grilled onions, lettuce, and juicy steak slices to finish.

# Notes:

01 - Slicing meat against the grain keeps it tender.
02 - Don’t have skirt steak? Try sirloin flap instead.
03 - Start with a little horseradish—you can always add more later.
