Instructions

Place the flat iron steak in a zipper bag. Add the lime juice, oil, agave syrup, salt, cumin, chipotle powder, cilantro and garlic cloves. Close the bag and massage the marinade all over the steak.
Place it in the fridge to marinate for at least 2 hours, or up to 10 hours.
After the steak has marinated, heat a grill to high heat.
Once the grill is hot, use tongs to remove the steak from the marinade and place it on the grill. Grill the steak for 5 minutes per side for a medium-rare steak. Insert an instant read thermometer into the steak. Remove the steak once it reads 130°F for a medium rare steak. For a medium steak, wait until it reaches 140°F and for a medium well steak, wait until it reaches 150°F. The steak will rise approximately 5 degrees after you remove it from the grill and let it rest.
Remove the steak from the grill when it reaches your desired temperature. Place it on a cutting board and let it rest for 5-10 minutes.
Use a sharp knife to slice the steak against the grain. You can then dice it into cubes to load up your tacos.
Heat the tortillas for 30 seconds per side on the grill, then add the steak to the tortillas, and add the toppings of your choice, like diced onions, fresh cilantro, or guacamole.

Notes

If you don't have a grill, you can cook the steak on the stovetop or in the oven.

To cook the steak on the stovetop, use a cast iron skillet or grill pan, if available. If not, use the heaviest bottom largest skillet you have. Turn the stove on to high heat. Once the skillet is hot, add the marinated steak and cook for 5-7 minutes per side. To cook the steak in the oven, turn the broiler on to low. Place the steak on a large rimmed baking sheet, on the middle rack of the oven, and cook for 4-6 minutes per side. If using this method, be sure to keep an eye on the steak while it’s cooking as oven broilers can vary in temperature and you don’t want the steak to burn.

I do not recommend marinating the steak for more than 10 hours. The acidity of the marinade will start to break down the proteins in the meat and can cause the steak to become mushy.
The marinade can be made up to 2 days in advance and stored in the refrigerator until you’re ready to marinate the steak.
This recipe can be used to marinate up to 2 pounds of steak. You can easily double the marinade ingredients to make 4 pounds of meat to feed a crowd at a party or BBQ.
This recipe makes 12 tacos, and I recommend 3 tacos per person, making the serving for this recipe 4 people.
To make a spicy marinade for the steak, add 1 teaspoon cayenne pepper, or 2 tablespoons hot sauce to the other marinade ingredients.
This recipe is naturally gluten free, when the steak is served on corn tortillas.
