Panfried Flank Steak with Mushroom Ragoût

This pan-fried flank steak with mushroom ragoût is a sophisticated yet simple high-protein meal that makes the most of rich, earthy flavours. By searing the steak and finishing the sauce in the same pan, you capture all the savoury juices, creating a deeply flavoured tomato and mushroom topping. The addition of fresh rosemary and a hint of chilli flakes provides a warming aromatic quality that complements the beef perfectly.

Ideal for a nutritious mid-week dinner or a relaxed weekend treat, this dish is naturally satisfying and low in carbohydrates. Serving the steak thinly sliced against the grain ensures a tender texture, while the vibrant ragoût adds moisture and brightness to every bite. Pair it with steamed seasonal greens or a crisp salad for a balanced, restaurant-quality meal at home.

How to make Panfried Flank Steak with Mushroom Ragoût

Put oven rack in middle position and preheat oven to 93°C.

Pat steak dry. Mix together salt and pepper in a small bowl, then rub three fourths of salt mixture on both sides of steak.

Heat 1 tablespoon oil in a 12-inch heavy skillet over moderately high heat until hot but not smoking, then sauté meat, turning over once, 6 to 8 minutes total for rare (depending on thickness of steak). Transfer to a baking pan and keep warm in oven while making ragout.

Heat remaining 2 tablespoons oil in uncleaned skillet over moderately high heat until hot but not smoking, then sauté garlic, rosemary, and red-pepper flakes, stirring, until fragrant, about 30 seconds. Add mushrooms and remaining salt mixture and sauté, stirring frequently and scraping up any brown bits, until mushrooms are tender but still juicy, 6 to 7 minutes. Add tomatoes with their juice and sugar, then simmer, stirring occasionally, until liquid is reduced by about two thirds, 5 to 8 minutes.

Transfer steak to a cutting board and pour any meat juices from baking pan into mushroom ragout. Holding knife at a 45-degree angle, cut steak across the grain into thin slices. Serve topped with ragout.
