This flank steak recipe is savoury and perfectly seasoned with a dried mushroom rub. Perfect for Dad on Father's Day!
Combine ground red pepper flakes, porcini powder, sugar, kosher salt, and black pepper in a small bowl.
Rub porcini powder mixture all over steak and set aside.
Heat butter and oil in a large skillet (cast iron would be ideal) over medium heat. Add steak to the hot pan and cook for 4-6 minutes per side, flipping once when the bottom is browned and crisp.
Remove from pan and let rest for 2 minutes.
Thinly slice and top with any desired garnishes.
