Combine the seasoned salt, Italian seasoning, black pepper, garlic powder, and onion powder in a small bowl.
1 tablespoon seasoned salt, 1 tablespoon Italian seasoning, ½ teaspoon ground black pepper, ½ teaspoon garlic powder, ½ teaspoon onion powder
Season all sides of the steak with the spice mixture. Use all of the mixture for 1 ½ pounds of steak. If your steak is smaller, you may not need all of it.
1 ½ pounds flat iron steak
Heat a cast iron or heavy-bottomed skillet over medium heat. Add the butter and let it melt.
3 tablespoons unsalted butter
Place the steak in the hot skillet. Cook for 5 to 6 minutes without moving it, then flip and cook for another 5 to 6 minutes, or until it reaches your preferred doneness.
Transfer the steak to a plate and let it rest for 5 to 10 minutes. Slice against the grain before serving.
Notes
Cook time: The cooking time depends on the thickness of the steak and how done you like it. The steaks used for this recipe are usually about 1 to 1½ inches thick.
Doneness: Use an instant-read thermometer for the most accurate results. Medium-rare is 130°F to 135°F, medium is 140°F to 145°F, and medium-well is 150°F to 155°F. The USDA recommends cooking beef steaks to 145°F followed by at least a 3-minute rest.
Seasoned salt: Don’t replace the seasoned salt with the same amount of table salt. If using table salt, start with about half as much.
Optional marinade: Whisk the seasoning blend with ½ cup olive oil and ¼ cup red wine vinegar. Add the steak and marinate it in the refrigerator for about 30 minutes before cooking.
Storage and reheating: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat the steak in a skillet over low heat with a small amount of butter until warmed through.
