Ingredients
For the steak tacos
- ▢ 1.5 lbs Flank steak
- ▢ 1 Flank steak marinade
- ▢ 2 tbsp Olive oil
- ▢ 2 Peppers seeds removed and sliced into rings
- ▢ 1 Onion sliced into rings
- ▢ Salt and Pepper
- ▢ Corn tortillas or flour tortillas
Taco Toppings:
- ▢ Lime Wedges
- ▢ Cotija Cheese
- ▢ Pico de gallo
- ▢ Fresh cilantro
- ▢ Sliced jalapeno or hot sauce
Instructions
Prep & marinate the steak
-
Start by removing your steak from the package and patting it dry with paper towels. Trim the meat, if needed, of any stray pieces of fat hanging off.
-
Then marinate the flank steak for 6 to 12 hours in the flank steak marinade.
Prep the Grill
-
When ready to cook, prep the grill for indirect heat by building a 2-zone fire. Do this by lighting charcoal in a charcoal chimney.
-
When it’s 70% ashed over, carefully pour the charcoal into a pile on one side of the grill.
-
Cover with the grate and lid and adjust the airflow as needed to get the grill to around 400 degrees F. Let the grill heat up.
-
Meanwhile, remove the steak from the marinade and pat dry.
-
Toss the peppers and onions in oil and season with a light sprinkle of salt and pepper.
Grill the flank steak tacos
-
When the grill is hot, arrange the flank steak on the hot side of the grill.
-
After about 7 minutes, when the steak has a good sear from edge to edge, flip the steak and continue to cook until it reaches an internal temperature of 130 degrees F for medium rare with an digital meat thermomter.
-
Place the grilled flank steak on a clean baking sheet and tent it with aluminum foil to rest.
-
While the steak rests, grill the peppers and onions, rotating from the cooler to the hot side of the grill to avoid burning them.
-
Add the tortillas and work in a rotation as well from the cooler to the hot side to soften them and add a bit of golden brown color.
-
Wrap the tortillas in foil to keep them warm for serving, and add the veggies to the platter with the steak.
Rest slice and serve
-
On a clean cutting board, slice the tender flank steak into thin strips against the grain.
-
Then chop the flank steak into bite-sized pieces. Roughly chop the grilled onions and peppers too for these easy flank steak tacos.
-
Arrange all of your favorite toppings and let everyone build their tacos (or make this recipe for taco salads) and enjoy.
