STEAK FRITES WITH RED WINE REDUCTION

Steps:

• Preheat the oven to 425 degrees F. Line a rimmed baking sheet with paper towels or a wire rack.
• Bring a large pot of water to a boil and heavily season it with salt until it tastes like the sea. Add the sliced potatoes and boil until tender and a paring knife easily pierces the potatoes, about 5 minutes. Carefully remove the slices from the pot with a slotted spoon and lay on the prepared baking sheet to dry, about 5 minutes.
• Meanwhile, pour about 1 inch of the oil into a Dutch oven. Heat over medium-high heat until it registers 350 degrees F on a deep-fry thermometer.
• Once dried, fry the potatoes in batches, turning them occasionally, until golden brown, 6 to 7 minutes. Drain the fries on the paper towels or wire rack. Transfer to a large bowl. Set aside a little of the parsley for garnishing the steaks. Add the remaining parsley to the bowl along with salt and pepper to taste and toss.
• Meanwhile, heat a large cast-iron skillet over medium-high heat until almost smoking. Season all sides of the filets with salt and use your hands or a pastry brush to coat them with oil. Sear until browned, 2 to 3 minutes per side. Immediately transfer the skillet to the oven and roast until an instant-read thermometer inserted into the middle of each steak registers 125 to 130 degrees F for medium-rare, 5 to 7 minutes. Remove the steaks from the oven and set aside on a plate to rest for 5 minutes before serving.
• Combine the wine, vinegar, thyme and shallots in a small skillet over medium-high heat. Boil until the wine is reduced by half, about 6 minutes. Reduce the heat to low, remove and discard the thyme and stir in the heavy cream. Stir in the butter a chunk or two at a time until melted. Season with salt and pepper and set aside.
• Place the steaks and fries on plates. Drizzle the steaks with the sauce, sprinkle with the reserved parsley and serve immediately.
