Ingredients
 

  • 1.5 pound flank steak
  • 1/2 cup steak marinade, I love Allegro
  • 2 tablespoons olive oil
  • 2 tablespoons lime juice
  • 1 tablespoon minced garlic
  • 1/4 cup jalapeño, seeded and chopped
  • 1/4 cup red onion, chopped
  • 2 tablespoons fajita seasoning*, see note below

Instructions
 

  • Combine the steak marinade, olive oil, lime juice, garlic, red onion, and jalapenos. Pour the marinade over the steak and marinade at least 30 minutes (the longer the better).
  • When ready to cook, heat a skillet, griddle or grill to high heat (approximately 400 degrees).
  • Sprinkle the fajita seasoning on the top (least fatty side) of the steak. Place the steak fatty side down and cook for approximately 6 minutes. Flip and cook an additional 5-6 minutes.**

**Use a meat thermometer to determine when to remove your steak follow this as a guide:

  • Medium Rare: 135 degrees F or 57 degrees C Medium: 145 degrees F or 63 degrees C Medium Well: 150 degrees F or 66 degrees C Well: 160 degrees F or 71 degrees C

Notes

I use a fajita seasoning blend for this recipe, if you prefer, you can use taco seasoning. The Fajita seasoning blend I reccomend is listed below. You will need 2 tablespoons of this blend for the marinated flank steak.

Fajita seasoning blend

  • 1/4 cup chili powder
  • 2 tablespoons paprika
  • 1 tablespoon cumin
  • 1 tablespoon onion powder
  • 1 tablespoon garlic powder
  • 2 teaspoons oregano
  • 1 teaspoon salt
  • 1 teaspoon pepper
