Instructions

Step 1

Heat oven to 150 degrees. On stovetop, heat cast-iron skillet to very hot. Brush steaks with 1/2 tablespoon oil. Season with salt and pepper. Sear steaks in skillet very briefly, less than a minute a side, just enough to brown. Place meat in a baking dish in oven for 1 1/2 hours.

Step 2

For chimichurri, combine parsley, thyme, garlic and shallot in food processor and pulse until minced. Transfer to a bowl, add vinegar, paprika and 5 tablespoons oil. Season with salt and pepper. Set aside. Heat remaining oil in skillet used for meat, add mushrooms and sauté until wilted. Season with salt. Set aside.

Step 3

When steaks are done, slice and place on a platter. Reheat mushrooms, remove from heat, toss with chimichurri and arrange alongside steak.
