This flavorful dish combines tender flat iron steak with a savory Asian-inspired marinade that’s quick to prepare. Perfect for a weeknight dinner, it’s packed with bold tastes that will satisfy your cravings in no time.
In a bowl, mix together the soy sauce, vinegar, brown sugar, green onions, garlic, and mustard powder until well combined. Pour the marinade into a resealable plastic bag, add the steak, and give it a good toss to make sure it’s fully coated. Seal the bag, press out any extra air, and pop it in the fridge for 3 to 4 hours to soak up all those flavors.
When you're ready to cook, take the steak out of the marinade and throw the leftover liquid away. Heat a non-stick skillet over medium-high heat. Once it’s hot, sear the steak for about a minute on each side until it’s nicely browned.
Then, turn the heat down a bit and keep cooking the steak, flipping every 5 minutes or so, until it reaches your preferred doneness. If you have a meat thermometer, aim for about 140°F (60°C) for medium. When it’s done, take the pan off the heat and let the steak rest for 3 to 5 minutes — this helps keep it juicy.
Finally, sprinkle some sesame seeds over the top before slicing and serving. Enjoy!
- Let the steak rest at room temperature before cooking to ensure even doneness.
- Use a hot grill or skillet to get a nice sear and lock in the juices.
- Slice the steak against the grain for maximum tenderness.
This dish offers a perfect balance of savory and tangy flavors with a hint of sweetness. The flat iron steak stays tender and juicy, making it a great choice for a quick and satisfying meal. Plus, the Asian-inspired marinade adds a vibrant twist that’s easy to prepare.
Serve with steamed jasmine rice or noodles and a side of stir-fried vegetables like bok choy or snap peas. A fresh cucumber salad or pickled radishes can add a refreshing contrast to the rich flavors.
Store leftover steak in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat to avoid overcooking, or enjoy cold in salads or sandwiches for a quick meal.
