Recipe Information
Ingredients
- 2 pieces (6-8 oz each) flat iron steak
- 1 teaspoon salt
- 1 teaspoon black pepper
- 2 tablespoons olive oil
- 2 tablespoons unsalted butter
- 2 whole shallots, finely minced
- 2 whole garlic cloves, minced
- 1 cup cognac
- 3 cups beef stock
- 0.5 cup heavy cream
- 1 teaspoon fresh thyme, leaves only
Instructions
Remove the flat iron steaks from the refrigerator about 30 minutes before cooking to allow them to come to room temperature.
Pat the steaks dry with paper towels. Season both sides liberally with 1 teaspoon of salt and 1 teaspoon of black pepper.
Heat a heavy skillet or cast-iron pan over medium-high heat. Add 2 tablespoons of olive oil and let it heat until shimmering.
Place the steaks in the hot pan and sear for 3-4 minutes on each side for medium-rare, or longer for desired doneness. Use a meat thermometer to ensure proper cooking. Remove the steaks from the pan and let them rest on a cutting board, tented loosely with foil.
Lower the heat to medium and add 2 tablespoons of unsalted butter to the pan. Once the butter has melted, stir in the minced shallots and garlic. Cook for 2-3 minutes, stirring frequently, until softened and fragrant.
Carefully pour in 1 cup of cognac. Stir, scraping the bottom of the pan with a wooden spoon to deglaze and incorporate any browned bits. Let the cognac simmer and reduce by half, about 3-4 minutes.
Add 3 cups of beef stock to the pan. Increase the heat to medium-high and bring the mixture to a boil, then reduce the heat and simmer until the liquid has reduced by half, about 10 minutes.
Stir in 0.5 cup of heavy cream and 1 teaspoon of fresh thyme leaves. Let the sauce simmer for 2-3 minutes, stirring occasionally, until slightly thickened.
Taste the sauce and adjust seasoning with salt and pepper as needed.
Slice the rested steaks against the grain into thin strips. Serve the steak with the cognac sauce drizzled over the top. Pair with roasted vegetables or mashed potatoes for a complete meal.
