Ingredients and Preparation

The beauty of this recipe lies in its use of simple, fresh ingredients and a few bold techniques. Here’s everything you need to get started:

For the Grilled Steak:

• 1½ to 2 lbs skirt steak or flank steak
• 3 tbsp avocado oil (or any neutral oil)
• 1½ tsp kosher salt
• 1 tsp freshly ground black pepper
• 1½ tsp ground cumin
• 1 tsp garlic powder
• 1 tsp onion powder
• Juice of 1 lime

For the Avocado-Tomatillo Salsa:

• 1 large ripe avocado, peeled and pitted
• 3 medium tomatillos, husked and rinsed
• 1–2 cloves garlic
• ½ small red onion, chopped
• ½ to 1 jalapeño pepper, seeded (optional, depending on heat preference)
• Juice of 1 lime
• ¼ cup fresh cilantro leaves
• Salt to taste
• 2 tbsp water (to adjust texture if needed)

Optional Toppings:

• Finely chopped red onion
• Chopped fresh cilantro
• Crumbled queso fresco or shredded sharp cheddar
• Pickled red onions
• Lime wedges

For Serving:

• Corn or flour tortillas, warmed

Preparation Tips:

• Allow your steak to rest at room temperature for about 20 minutes before grilling for even cooking.
• Fresh, ripe avocados are essential for a creamy salsa. If your avocado is firm, wait another day.
• Char the tomatillos slightly for added depth in the salsa.

Step-by-Step Instructions

Here’s how to bring it all together in a few simple steps.

1. Prepare and Marinate the Steak

• In a large bowl, whisk together avocado oil, lime juice, salt, pepper, cumin, garlic powder, and onion powder.
• Place the steak in the bowl and use your hands to massage the marinade into the meat. Ensure every part is well coated.
• Cover the bowl and refrigerate for at least 30 minutes. For deeper flavor, marinate for up to 2 hours.

2. Make the Avocado-Tomatillo Salsa

• Place the tomatillos on a hot dry skillet or grill pan over medium-high heat. Cook until lightly charred on all sides (about 5–7 minutes).
• In a blender or food processor, combine the charred tomatillos, avocado, garlic, red onion, jalapeño, lime juice, and cilantro.
• Blend until smooth, adding a little water as needed to achieve your desired consistency.
• Taste and season with salt. Set aside in the fridge until ready to serve.

3. Grill the Steak

• Preheat your grill (or grill pan) over high heat.
• Once hot, grill the steak for 3–5 minutes per side, depending on thickness and desired doneness. Skirt steak is best at medium-rare.
• Remove from the grill and let rest for 5–10 minutes before slicing.
• Cut the steak into thin strips, against the grain for tenderness.

4. Warm the Tortillas

• Warm tortillas on the grill for 20–30 seconds per side or in a dry skillet over medium heat.
• Keep warm in a clean kitchen towel until ready to assemble.

5. Assemble the Tacos

• Place a few slices of steak on each tortilla.
• Spoon on the avocado-tomatillo salsa.
• Add desired toppings such as chopped onion, cilantro, crumbled cheese, and pickled onions.
• Finish with a squeeze of lime.

Beginner Tips and Notes

If you’re new to cooking steak or tacos in general, here are some helpful tips to guide you through:

• Choosing the Right Cut: Skirt steak or flank steak works best due to their rich beefy flavor and quick cooking time. Both cuts are thin and benefit from high heat and a short rest.
• Marinate Smart: A 30-minute marination time is ideal for quick flavor penetration. Avoid over-marinating, especially with acidic components like lime, which can toughen the meat.
• Rest Is Key: Resting the steak before slicing is crucial. It allows juices to redistribute throughout the meat, keeping it moist.
• Go for Charring: Slightly charring your tomatillos and tortillas adds a smoky depth that elevates the overall taste.
• Don’t Overload the Tacos: A few simple toppings let the steak and salsa shine. Avoid stuffing them too full—you want each bite balanced.
• Batch Cooking Tip: If feeding a crowd, cook the steak in batches and keep the cooked meat loosely covered with foil in a warm oven until ready to serve.

Serving Suggestions

These grilled steak tacos are satisfying on their own but can also shine as part of a larger Mexican-inspired spread. Consider pairing them with:

• Mexican Street Corn (Elote): Grilled corn on the cob slathered with spiced mayo, cotija cheese, and lime juice.
• Cilantro Lime Rice or Mexican Red Rice: A great side dish to soak up the salsa.
• Refried Black Beans or Pinto Beans: A creamy, hearty addition that balances the bold flavors of the tacos.
• Homemade Guacamole and Tortilla Chips: You can never go wrong with this classic.
• Fresh Fruit Agua Fresca or Limeade: To cool off the spice and complement the citrus in the salsa.

Want a casual dinner? Serve the tacos buffet-style and let everyone build their own. This also works well for family dinners or gatherings, giving people the freedom to customize based on their preferences.
