steak-taco-guacamole RecipeLeigh Beisch


  • Steak:
  • 3 teaspoons vegetable oil, divided
  • 2 teaspoons dried Mexican oregano
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon cayenne pepper
  • 1/4 teaspoon black pepper
  • 2 garlic cloves, minced (or pressed through a garlic press)
  • 1 (1 1/2-pound) flank steak, fat trimmed
  • 3 cups vertically sliced onion (about 2 medium onions)
  • 2 cups red and yellow bell pepper strips (about 2 large peppers)
  • 2 jalapeño peppers (or 1 serrano pepper), halved lengthwise and thinly sliced, with seeds
  • Guacamole:
  • 2 ripe avocados, peeled and seeded
  • 1 garlic clove, minced (or pressed through a garlic press)
  • 2 teaspoons fresh lime juice
  • Kosher salt to taste
  • 12 (6-inch) flour tortillas, warmed


To prepare steak, combine 1 teaspoon oil and next 5 ingredients (through garlic) in a bowl. Rub steak with garlic-oil mixture; place in a large zip-top plastic bag. Seal; marinate in the refrigerator 1 hour, or overnight.

Lightly spray the rack of an outdoor grill with cooking spray. Heat to medium-high.

Heat remaining 2 teaspoons oil in a large nonstick skillet over medium-high heat. Add onion, bell pepper, and jalapeño; sauté 5 minutes (A). Keep warm.

Place the steak on the grill, and cook 4 minutes on each side (without turning) for medium, or to desired degree of doneness (B). Let stand 10 minutes on a cutting board before slicing crosswise into 1/3-inch-thick slices.

To prepare guacamole, combine all ingredients in a small bowl, and mix well, mashing with a pestle (C) or fork until mixture is chunky.

Heat the tortillas in a covered casserole in a 300° oven until warm and pliable. Place a small amount of meat in each tortilla; top with the onion-pepper mixture and guacamole.


    Most of the fat in this recipe is the good-for-you monounsaturated kind in the avocado, so don't let it deter (or disturb) you.

  • Yield: Serves 6 (serving size: 2 tortillas, 1/3 cup meat, 2/3 cup onion mixture, 2 tablespoons guacamole)
