Equipment

Ingredients

For the Shallot butter

  • 1 Shallot minced
  • 1 tbsp fresh Parsley minced
  • ¼ tsp kosher Salt
  • 1 tsp grated Parmesan
  • 4 tbsp unsalted Butter room temperature

For the Flat Iron Steak

  • 1 lbs flat iron steak
  • Kosher salt
  • 1 tbsp oil neutral oil like avocado oil
  • Freshly ground black pepper

Instructions

Prep the steak

  • Meanwhile, remove the flat iron steak from the package and pat it dry with paper towels.
  • If it is a large steak, consider slicing it in half, right at the middle to fit better in your pan.
  • Season the steak liberally with salt on all sides and allow it to sit at room temperature for 30 to 45 minutes.

Cook the steak

  • When ready to cook, preheat a large cast iron or carbon steel skillet over medium high heat.
  • Add the oil and let it preheat until it’s shiny and just starting to smoke.
  • Carefully add the steak, using a splatter guard if needed to minimize mess.
  • Cook for 2 to 3 minutes, moving the steak around the pan for an even sear, as a crust forms.
  • Flip and cook 2 to 3 minutes longer, until the steak reaches 130 degrees F with a digital meat thermotmer.

Rest

  • Remove the steak from the skillet and add a knob of the shallot butter over top while it rests for 5 to 7 minutes.

Slice and Serve

  • Slice the steak into thin, ¼” thick slices, at an angle against the grain.
  • Arrange on a platter and garnish with a bit more of the shallot butter to melt over the top of the steak and a pinch of freshly ground black pepper.
  • Serve immediately.
