Instructions

Combine all steak ingredients in a bowl except for the oil. Add the steak and transfer to a ziplock. Press out as much air as possible to ensure that the the marinade is surrounding the meat. Refrigerate for at least 6 hours, or overnight.
Stir together the sauce ingredients and refrigerate while the steak is marinating.
Remove steak from the marinade and dry thoroughly.
Broil on high in a preheated broiler for 3-4 minutes per side. Allow the steaks to rest for 10 minutes.
Slice thin against the grain. Serve with the horseradish sauce.

Notes

Alternatively, heat a large cast iron pan over high heat. When the pan is hot, add the seasoned steak and sear well on both sides, about 5 minutes per side, or until the internal temperature measures 125ºF. Remove steak to a cutting board to rest for 5 minutes.
