STEAK: Flank steak has a rectangular shape with less marbling than other cuts of beef, but with the right marinade and proper slicing technique, it comes out tender, juicy, and filled with flavor. Skirt steak is another lean option that’s often used interchangeably with flank, so don’t hesitate to use either. Try adding this DIY seasoning blend to the marinade or use it as a rub, if desired.
TORTILLAS: Corn tortillas are a favorite, but flour tortillas work well too. Why not crush up tortilla chips and add some extra lettuce for a crunchy taco salad?
How to Cook Flank Steak for Tacos
Follow a few simple instructions for the best tender grilled steak (refer to this grilled flank steak recipe)
- Add marinade ingredients to a zippered bag. Add flank steak and refrigerate. PRO TIP: Marinate steak for at least two hours or overnight for best results.
- Prepare toppings.
- Place marinated flank steak on the grill and cook to desired doneness using an instant-read meat thermometer, flipping and brushing with extra marinade as it cooks. NOTE: The internal temperature of flank steak should be 125°F for rare and 130°F for medium-rare flank steak.
- Remove the steak from the grill, cover with foil and allow to rest (the meat will continue to cook a bit, referred to as carryover cooking).
- Heat flour or corn tortillas on a gas stovetop or electric burner until they are soft and browned on both sides. Add desired toppings, a squeeze of lime and chopped cilantro to finish.
How to Cut Flank Steak
Before slicing grilled flank steak, look at the direction which the meat fibers run and cut against them at a 45° angle. This breaks down the fibers for slices that are tender and easy to chew.
A Mexican inspired dinner has never been easier or more fun! Set out a spread and let everyone build their own!
- Veggies: Shredded lettuce, cabbage slaw, diced tomatoes, avocados, onions, peppers bring flavor and texture to these tacos.
- Sauces: Salsa, classic guacamole, guacamole with tomatoes, or smoked tomato guacamole are all flavorful and delicious sauce options. Don’t forget the sour cream!
- Cheese: Mexican blend, cheddar, Monterey Jack, or crumbled cotija are all delicious.
- Toppings: Sliced jalapenos, black olives, and green chiles are just the beginning. Use your imagination for unique taco variations.
Tips for the Best Tacos
