For the Carne Asada

For the Fries

For Serving (All Optional)

  • sour cream
  • guacamole see Notes
  • cilantro chopped
  • tomatoes diced
  • jalapeños diced or sliced


  • Place all ingredients for the carne asada marinade in a large bowl. Whisk until thoroughly combined.
  • Add flank steak to marinade. Cover bowl and refrigerate 4 to 12 hours.
  • Toward end of marinating time, prepare fries. Preheat oven to 400° Fahrenheit. Wash potatoes, then cut into even-sized matchsticks. Place fries in large bowl with avocado oil and seasonings. Toss to coat completely.
  • Arrange fries on baking sheet in single layer. Bake 20 minutes, then toss or flip fries. Bake additional 10 minutes or until fries are crispy.
    Fries on baking sheet
  • While fries bake, heat 1 tablespoon or so avocado oil in large skillet over medium-high heat.
  • Cut steak into thin strips or bite-sized pieces, then add to skillet. Cook 4 to 8 minutes per side or until desired temperature is reached. Thinner strips/smaller pieces will need less time. For medium steak, cook to internal temperature of 145° Fahrenheit.
  • To serve, sprinkle Mexican shredded cheese over fries. Return fries to oven for 2-5 minutes to melt cheese, or skip this step and leave the cheese unmelted.
