Aji Marinated Flat-Iron Tacos

Aji is a South American sauce prevalent in Columbia and Peru. Depending on the region, this sauce (or sometimes a chunky salsa) can range from mild to super hot. We'll be using the milder version to marinate the flat-iron steaks for this recipe.

  • 2 pounds flat iron steaks
  • 12-14 corn tortillas
  • 1 1/2 cups guacamole
  • for marinade:
  • 1 small onion, roughly chopped
  • juice of 2 limes
  • 2 large jalapenos, seeded and roughly chopped
  • 1/4 cup cilantro
  • 2 cloves garlic minced
  • 1 tablespoon olive oil
  • 2 teaspoons salt
  • 1-2 teaspoons habanero pepper sauce (optional)
  • 1 teaspoon black pepper


  • Place all marinade ingredients into a food processor. Process until mixture is thick and smooth. Add more lime juice or oil if mixture remains chunky.
  • Place flat iron steaks in a resealable plastic bag. Pour aji marinade over steaks and work it in making sure all surfaces of the meat are well coated. Seal bag and place into refrigerator for 6-24 hours.
  • Preheat grill for medium-high heat.
  • Remove steaks from bag and place onto grill. Cook 5-7 minutes per side or until steak reaches desired doneness. Place tortillas in a large piece of aluminum foil, wrap and place on the cooler part of the grill for about 5-7 minutes, turning once.
  • Once cooked, remove steaks from grill and place onto a cutting board. Remove tortillas and set aside. Slice steaks into thin strips and serve in warmed tortillas with guacamole. If preferred, make a double batch of the aji sauce and reserve half to serve with the tacos.
