Grilled Steak Tacos with Jalapeño Crema

Quick Answer

Grilled Steak Tacos marinate skirt steak, grill it hot, and pile it into charred tortillas with quick-pickled onions and a roasted jalapeño crema.

Jump to Recipe

Steak tacos are at their best when the steak is doing more than occupying tortilla space. A hard sear or grill char gives the beef deep flavor, and slicing across the grain keeps each bite tender enough to eat without pulling the entire taco apart with your teeth. Then jalapeño crema comes in cool, tangy, and just spicy enough to keep the richness from taking over.

The crema matters because it spreads heat and acidity through every bite instead of leaving you with random jalapeño land mines. Lime, dairy, chile, and salt create a sauce that works with charred beef rather than fighting it. Fresh toppings—onion, cilantro, cabbage, tomato, whatever the recipe uses—bring crunch and brightness, but the steak and crema are the reason you came.

Warm the tortillas before assembly. A cold tortilla wrapped around hot steak feels like somebody remembered dinner but forgot hospitality. Once everything is ready, build small tacos and eat them while the contrast is still there: warm beef, cool crema, bright lime, soft tortilla, fresh toppings. The first taco usually looks neat. By the third, somebody has sauce on their wrist and has stopped caring. That is generally a sign dinner is going well.

Ingredients

Servings
  • pounds skirt steak
  • 3 tablespoons fresh lime juice
  • 2 tablespoons olive oil
  • 3 garlic cloves, minced
  • teaspoons ground cumin
  • 1 teaspoon ancho chile powder
  • teaspoons kosher salt
  • ½ teaspoon black pepper
  • 1 small red onion, thinly sliced
  • ½ cup apple cider vinegar
  • ½ cup hot water
  • 1 tablespoon granulated sugar
  • teaspoons kosher salt
  • 2 jalapeños
  • ¾ cup sour cream
  • ¼ cup mayonnaise
  • 2 tablespoons fresh lime juice
  • 1 small garlic clove
  • ½ teaspoon kosher salt
  • 2 tablespoons chopped cilantro
  • 12 small corn tortillas
  • ½ cup crumbled cotija cheese
  • ½ cup chopped cilantro
  • Lime wedges

Instructions

  1. 1Whisk the lime juice, olive oil, garlic, cumin, ancho chile powder, salt, and pepper. Coat the steak and refrigerate for 1 hour.
  2. 2Place the sliced onion in a bowl. Stir the vinegar, hot water, sugar, and salt together until dissolved, then pour over the onion. Let stand for at least 30 minutes.
  3. 3Char the jalapeños on a grill or under the broiler until blistered all over, 5–7 minutes. Stem them and remove the seeds for a milder crema.
  4. 4Blend the jalapeños, sour cream, mayonnaise, lime juice, garlic, salt, and cilantro until smooth. Refrigerate until needed.
  5. 5Heat a grill to high. Remove the steak from the marinade, pat off the excess, and grill for 3–5 minutes per side, until 128–133°F for medium-rare.
  6. 6Rest for 8 minutes, then slice very thinly across the grain and chop into bite-size pieces.
  7. 7Warm the tortillas on the grill for 20–30 seconds per side.
  8. 8Fill each tortilla with steak, drained pickled onion, jalapeño crema, cotija, and cilantro. Serve with lime wedges.

Pro Tips

  • Char the jalapeños until properly blistered and black in spots, not just lightly toasted. That real char is what gives the crema its smoky depth.
  • Let the onions pickle a full 30 minutes minimum. Less time and they're just vinegary raw onion instead of that bright, tangy crunch.
  • Slice the rested steak thin and chop it into bite-size pieces — skirt steak's grain is strong, and small pieces make every taco easy to eat.

Substitutions

cotija cheese → crumbled feta or queso fresco Cotija is salty and firm; feta is a close substitute, queso fresco is milder.
skirt steak → flank steak or flat iron Both take the marinade well; adjust grill time to thickness.
corn tortillas → small flour tortillas Corn is traditional here, but flour works if that's your preference.

Storage Instructions

Store the steak, pickled onions, and crema in separate airtight containers in the refrigerator for up to 3 days. Warm the steak briefly before assembling fresh tacos.

Make Ahead

The pickled onions and crema can both be made up to 3 days ahead and refrigerated — they improve with a little time. Marinate and grill the steak the day you plan to serve.

Freezing

Freeze the raw marinated steak for up to 2 months and thaw overnight before grilling. The crema and pickled onions don't freeze well, so make those fresh.
