Fajita Marinade

  • 1/2 cup oil (olive or avocado oil)
  • 1/4 cup lime juice
  • 1/4 cup cilantro, (minced)
  • 4 cloves of garlic, (minced)
  • 2 teaspoons oregano powder
  • 2 teaspoons chili powder
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon dried parsley
  • 1/2 teaspoon cumin 
  • 1 1/2 teaspoon salt and pepper, (to taste)
  • 1/4 teaspoon chili flakes (optional, to taste)


  • 8-10 tortillas (flour or corn tortillas), (slightly charred) 
  • 1 cup shredded Monterey Jack or Cheddar cheese
  • Salsa or Pico de Gallo
  • Guacamole
  • Shredded lettuce 
  • Fresh tomatoes
  • Sliced avocados 
  • Sliced green onions
  • Sour cream
  • Lime wedges
  • Fresh cilantro 



Preheat the broiler.

Make the fajita marinade by combining all ingredients in a large bowl.

Take 3 tablespoons of the marinade and place it in a smaller bowl. Add the veggies to the small bowl and toss well with the marinade. 

To the large bowl with the remaining marinade, add in 1/4 cup of Soy sauce and add the sliced lamb. Marinade the lamb and veggies anywhere between 10 minutes to 6 hours.

Take a baking sheet and arrange the lamb in a single layer.


Broil on high for 8-12 minutes until charred and cooked through*. Remove from the oven and set aside for 10 minutes.

*Note: The USDA recommends that lamb reach an internal temperature of at least 145 degrees F with a 3-minute rest.

Switch the oven to Bake at 400 degrees F. Using the same baking sheet, spread the veggies over the sheet and roast for 15 minutes.

In the meantime, slice up your lamb into smaller fajita size pieces. Throw them back on the baking sheet with the veggies once they're ready.  Broil both the lamb and veggies on high for 3 minutes until charred.

Serve the lamb fajitas with the veggies on the same sheet with the different toppings around it.
