Grilled flat iron steak is tender and delicious with the tastiest Asian marinade. It melts in your mouth! The flavors are divine and it’s so easy to make.
I get so excited about food from the grill, especially when it’s a piece of delicious steak. The hubby is usually in charge of the grill and can cook the best steak ever. I am not exaggerating either, his steaks are amazing. He loves cooking steaks, and I usually cook the other meats or vegetables. But for this recipe I decided to grill it myself, I was testing out different cuts of meats. I found this tender delicious cut of flat iron steak at the store and decided to give it a try.
Flat Iron Steak vs. Flank Steak
Flat iron steaks and flank steaks look similar, but they taste different. The texture is very different. Flat iron steak is more tender than flank steak. Flat iron steak if cooked properly is so tender and buttery. Flank steak is also delicious but is not as tender and it has a different texture.
Grilling the Perfect Flat Iron Steak
The secret to grilling a flat iron steak to perfection is the level of heat. I have tried different temperatures and found that cooking at low-medium heat in the grill yields the best results. I start at medium-high heat to create beautiful grill marks, then lower the heat to low-medium to cook the steak through. The results will be the most tender piece of meat that melts in your mouth. The grilled flat iron steak when grilled to perfection taste more tender than a filet mignon. Our family loves our steaks medium to medium rare.
This grilled flat iron steak it’s super easy to make and it’s so versatile, you can serve it with a rice, veggie, salad, make tacos, make burritos, etc.
