Flank Steak Tacos
Grilled with charred edges caramelized from a marinade, sliced across the grain for tenderness and served up as the main course, in these flank steak tacos, I’m loving each and every bite.
For these tacos I’m using leftover flank steak from the night before when I made my go to marinated and grilled flank steak. Feel free to grill up a fresh one and use in this recipe, too!
What’s in the marinade?
My grilled flank steak starts with a marinade hitting all the flavor notes of sweet, savory, salty and the acid coming from lemon. A kiss of heat from sriracha is completely optional, but highly recommended.
Cooking times for grilling flank steak
You’ll want to cook flank to a temperature of 125°F for a Rare, 135°F for Medium Rare, 145°F for Medium, 155°F is Medium Well, and 165°F for Well Done.
This flank steak is always on rotation for lunches or dinners because it’s so easy and quick. Even with a quick douse of soy sauce and sprinkle Montreal seasoning while the BBQ grill heats up when low on time, it delivers.

Flank Steak Tacos
- 2 lb flank steak
- corn tortillas (charred on grill)
- 1/4 cup olive oil

- 1/4 cup brown sugar
- 1 tbsp sriracha sauce (or other hot sauce) optional optional

- Crush the garlic cloves with the side of a knife to break open. Set aside.
- In a small bowl mix together the marinade ingredients and set aside.
- With a sharp knife create cross hatch marks on both sides of flank steak (See video). Just cut the surface slightly, don't cut through meat. This is optional, but I love the crispy edges and caramelized flavors this brings.

- Heat grill to 350-400°Remove flank steak from marinade. Reserve marinade for basting. Grill flank steak 6 minutes per side, or until an internal temperature of 130-135°F is reached for medium rare. Baste several times during grilling.
- Place on a cutting board and allow meat to rest 10 minutes before slicing. Be sure to cut thin slices across the grain for a tender piece of meat.
- Char the corn tortillas on both sides, keep warm.
- Fill warm tortilla with sliced flank steak, lettuce, cheese and pico de gallo. Squeeze some lime on top and dig in.
