•
1 1/2 teaspoons kosher salt
•
1 teaspoon freshly ground black pepper
•
1/2 teaspoon garlic powder
•
1/2 teaspoon onion powder
•
1 tablespoon vegetable oil, divided
•
1/2 pound cremini mushrooms
•
1/2 cup Burgundy wine
•
1 cup beef stock
•
1 tablespoon butter, softened
•
1 tablespoon all-purpose flour
•

Directions
1
Preheat the oven to 325 degrees F (165 degrees C).
2
Season both sides flat iron steak with salt, black pepper, garlic powder, and onion powder. Heat a heavy, oven-proof skillet over medium-high heat; add 2 teaspoons vegetable oil and heat until oil shimmers. Add steak; sear until well browned, about 3 minutes per side. Transfer steak to a plate.
3
Reduce heat to medium; add remaining 1 teaspoon vegetable oil to skillet. Add mushrooms; cook and stir until wilted and browned, about 10 minutes. Reduce heat to medium-low; add wine to skillet and bring to a boil. Cook until wine is slightly reduced, 3 to 5 minutes; add beef stock and bring to a simmer.
4
Mash butter and flour in a small bowl into a paste using a fork; stir into mushroom mixture and simmer until sauce is thickened, about 5 minutes. Return flat iron steak to the skillet.
5
Cook in the preheated oven until steak is barely pink inside, about 10 minutes. Cut steak into thin slices on the diagonal against the grain; place on a platter.
6
Stir cream into mushroom sauce until heated through, 1 to 2 minutes; pour over steak and garnish with chives.
