Directions
Argentino Sauce
In a blender or food processor, combine olive oil, shallot, mayo, sour cream, vinegar, Dijon mustard, Steak Argentino seasoning, jalapeño, cilantro, parsley, lime juice, and lime zest.
Blend until smooth and creamy.
If needed, add 1–2 tablespoons water to thin the sauce slightly.
Taste and adjust seasoning if desired.
Refrigerate until ready to serve.
Steak Marinade and Tacos
In a bowl, combine olive oil, lime juice, lemon juice, orange juice, Steak Argentino seasoning, and cilantro.
Place steak in a resealable bag or shallow dish and pour marinade over the steak.
Marinate in the refrigerator for 2–6 hours.
Preheat grill to medium-high to high heat.
Remove steak from marinade and allow excess marinade to drip off.
Grill steak for about 4–5 minutes per side for medium-rare, depending on thickness.
Use a thermometer and remove steak around 130–135°F for medium-rare.
Transfer steak to a cutting board and rest for 5–10 minutes.
Slice steak thinly against the grain.
Warm tortillas on the grill or in a skillet until soft and lightly charred.
Fill tortillas with sliced steak and drizzle with Argentino sauce.
Top with optional toppings like pickled red onions, avocado slices, queso fresco, fresh cilantro, and lime wedges if desired.
Serve immediately.
Recipe Note
Avoid marinating overnight because the citrus can negatively affect the texture of the steak.
Allowing excess marinade to drip off helps improve browning and reduces flare-ups on the grill.
Flat iron steak works especially well for tacos because of its rich flavor and tenderness.
Warming tortillas directly on the grill adds additional flavor and texture.
Pickled red onions and avocado add acidity and creaminess that balance the rich steak and herb sauce especially well.
Slicing the steak against the grain helps maximize tenderness.
