Place all the ingredients except the steak and additional 2 TBSP oil into a deep container, and then blend with an immersion blender to make relatively smooth.
Add steak and marinade to a large Ziploc bag and shake to coat evenly.
Place skillet into oven (with steak in it!) and cook for an additional 10-15 minutes, until desired doneness (it stays the most tender if you keep it a little red).
Recipe Notes
This cut of meat, like most steaks, is best served medium to medium-rare.
