How to Make It

Follow these steps to create delicious street tacos.

Marinate the Beef

Pat the beef skirt steak dry with paper towels. In a shallow dish, combine 2 tablespoons vegetable oil, ground cumin, chili powder, dried oregano, garlic powder, onion powder, 0.5 teaspoon salt, 0.25 teaspoon black pepper, and 2 tablespoons lime juice. Add the steak, ensuring it is fully coated. Marinate at room temperature for at least 30 minutes or refrigerate for up to 4 hours.

Roast the Poblano Peppers

Preheat your oven to 200°C (400°F). Place the poblano peppers on a baking sheet. Roast for 15-20 minutes, turning once, until skins are blistered and charred. Transfer hot peppers to a bowl, cover tightly, and let steam for 10-15 minutes. Once cool enough to handle, peel away skin, remove stems and seeds, then roughly chop the tender flesh.

Make the Poblano-Avocado Crema

For the Poblano-Avocado Crema, combine the roasted poblano flesh, ripe avocado, plain yogurt, 1 small garlic clove, 1 tablespoon lime juice, and the remaining 0.5 teaspoon salt and 0.25 teaspoon black pepper in a blender or food processor. Blend until completely smooth and creamy. If the crema seems too thick, add water one teaspoon at a time until desired consistency. Taste and adjust seasoning if needed.

Grill the Steak

Preheat a grill or grill pan to medium-high heat. Lightly oil the hot grates. Remove steak from marinade, shaking off any excess. Grill skirt steak for 3-4 minutes per side for medium-rare, or longer to desired doneness. Remove from heat, tent loosely with foil, and let rest for 5-10 minutes. Thinly slice against the grain for maximum tenderness.

Warm the Tortillas

While the steak rests, warm the corn tortillas until pliable and toasty. Microwave them wrapped in a damp paper towel for 30-60 seconds, or heat briefly on a dry hot skillet for 15-20 seconds per side.

Assemble the Tacos

Place two warm corn tortillas on a plate. Arrange a generous portion of thinly sliced grilled steak across the tortillas. Top with finely diced white onion and fresh chopped cilantro. Finish with a generous drizzle of the vibrant green Poblano-Avocado Crema. Add extra finely chopped cilantro and a light dusting of smoked paprika on the side for visual interest. Serve immediately with extra lime wedges.

How to Store It

Fridge: 3-4 days in an airtight container.
Freezer: Yes, but best fresh for flavor.
Reheat: Microwave on medium for 1-2 minutes.

Tips for Best Results

• Allow the steak to marinate for at least 1 hour for deeper flavor.
• Let the steak rest before slicing to retain juices.
• Adjust the crema’s consistency with water for your preference.
• Warm tortillas just before serving for best texture.

Serving Suggestions

• Serve with extra lime wedges for brightness.
• Pair with traditional Mexican rice and beans.
• Enjoy with a side of fresh mango salsa for added sweetness.
