Beef Fajita Marinade

Tex-Mex Beef Fajitas

  • 1-1/2 pounds skirt or flank steak trimmed
  • 1 onion sliced
  • 1 red sweet pepper sliced
  • 1 green bell pepper sliced
  • 8 flour tortillas
  • chopped cilantro for garnish


Tex-Mex Beef Fajitas Marinade:

  • In a large zip-top plastic bag, add all the marinade ingredients.
  • Place the skirt or flank steak into marinade in the zip-top plastic bag. Close and turn and shake the bag to get the marinade to cover the entire steak.
  • Refrigerate for 1 or 2 hours but no more than 2 hours due to the pineapple juice in the marinade. You don't want the steak to get too mushy due to marinating too long.

Tex-Mex Beef Fajitas:

  • Remove the steak from the marinade and let marinade drain off the steak.
  • Prepare grill for cooking, or if cooking on top of the stove, add about a tablespoon of oil to a skillet or grill pan and place over medium-high heat.
  • Grill or cook the fajita meat for about 6 - 8 minutes and then turn and grill on the other side for another 6 - 8 minutes or until cooked to your preferred level of doneness.
  • Remove the steak from the grill. Cover with foil and set aside for now.
  • If cooking on the stove, add the sliced onions, and red and green peppers to the same pan that you cooked the fajita meat and cook 3 - 5 minutes over medium heat.
  • If grilling, spray a vegetable grilling rack with cooking spray and add the sliced vegetables. Grill the vegetables for 3 - 5 minutes or until the onions are soft and slightly browned on the edges.
  • Remove the vegetables and place them on a plate covered with foil. Set aside.
  • Heat the flour tortillas either on the grill or stove for per package instructions, or microwave for 30 seconds.
  • Place the fajita meat on a cutting board and slice the meat against the grain into thin slices. It is very important to slice against or across the grain, otherwise, the meat may be tough.
  • Place the sliced fajita meat and vegetables on a platter and serve the Tex-Mex Beef Fajitas with warm tortillas.
  • Enjoy!
