Ingredients

  • 1 flat iron steak brought to room temperature
  • 3-4 cloves roasted garlic
  • 1 sprig rosemary
  • 1 regular shallot thinly sliced
  • 2 tablespoons butter
  • 1 tablespoon olive oil
  • Kosher salt to taste
  • Fresh cracked black pepper to taste

Instructions

Preparation Steps

  • Gather all the tools and ingredients.
  • Preheat your oven to 425°F (220°C).
  • Slice the shallot thinly.

Cooking Instructions

    For the Crispy Shallots

    • Add the olive oil to a cast iron pan and heat over medium-high heat. When the oil shimmers, add the sliced shallot and a pinch of kosher salt.
    • Cook for 4-5 minutes, stirring until the shallots begin to crisp.
    • Remove from the pan with a fork or tongs, leaving the oil in the pan. Set aside.

    For the Pan-Seared Steak

    • Add the butter to the hot skillet. Turn the heat to high. When the butter has melted, lay the beef carefully so as not to splash the hot oil.
    • Add the rosemary to the pan, on the side.
    • After 2 minutes, using tongs, flip the meat. The beef should be nicely browned.
    • Cook for 2 minutes, basting the steak with the rosemary butter from the pan. Then put the pan in the oven.
    • Cook in the oven for 5-6 minutes, depending on your desired level of doneness.
    • Remove from the oven and set on the stove. Flip with tongs and baste again.
    • Remove the steak from the pan and set on the cutting board. Cover with foil and allow to rest for 5-10 minutes.
    • Slice against the grain, top with the crispy shallots and roasted garlic.
    • Serve hot and enjoy!
