The trick to a great crust on this flat iron steak is to use a very hot skillet; a large cast-iron or heavy stainless steel skillet works best. Have your hood fan on high—there will be some smoke. If you can't find flat iron steak in your local market, a top blade chuck or sirloin steak will work just fine.
1 (1-lb.) flat iron steak
2 teaspoons Montreal steak seasoning
1/4 teaspoon kosher salt
1 tablespoon vegetable oil
How to Make It
Rub steak evenly with steak seasoning and salt.
Cook in hot oil in a large skillet over medium-high heat 4 to 5 minutes on each side or to desired degree of doneness. Let stand 5 minutes. Cut diagonally across the grain into thin strips.
