Weeknight meals can’t get any easier. After an easy overnight marinade, you can grill up tender, flavorful steak tacos in under 10 minutes.

Raise your hand if you’ve bitten into a taco to find tough beef that isn’t bite-tender. Kind of sucks huh? You end up pulling out a mouthful of beef, leaving your shell with nothing but veg.

Aussie grassfed flat iron steaks are naturally more tender, making them the ideal choice for tacos. Marinating them for a few hours adds a pure south of the border punch.

After bathing in the marinade, the steak will grill up fast, just 3 minutes per side for medium rare.

Let the beef shine by keeping the toppings simple. My favorites include fresh onions, red cabbage, lime and cilantro.

Ingredients

  • 2 lbs Aussie grass-fed flat iron steaks
  • 2 cloves cloves garlic minced
  • 1/2 cup soy sauce
  • 1/4 cup red wine vinegar
  • juice of 2 limes
  • 1/2 tsp kosher salt
  • 1/2 tsp black pepper
  • 1/2 tsp garlic powder
  • 1/2 tsp onion powder
  • 1/2 tsp ground cumin
  • 1/4 tsp cayenne pepper

Instructions

  1. Mix all of the ingredients in a zip-top bag and marinate at room temperature for 2 hours or in the refrigerator overnight.
  2. Heat the grill to medium-high heat. Remove the meat from the marinade. Grill for 3 minutes per side.

  3. Remove from the grill, and let rest for 10 minutes. Slice the beef against grain.

  4. Serve with tortillas, onions, cabbage and limes.

Tips

When trimming a whole flat iron, cut the beef horizontally. There is a membrane that runs down the center of the cut. Removing this membrane ensures that every bite is taco tender.
