How to Make Cilantro Beef Tacos

1. Season the Steak

Pat the flank steak dry with paper towels. Season both sides evenly with salt and pepper.

2. Sear the Flank Steak

Heat 2 teaspoons of olive oil in a large skillet over medium-high heat.

Add the flank steak and cook for about 4–5 minutes per side, depending on thickness and your preferred level of doneness.

Transfer the steak to a cutting board and let it rest for about 5 minutes. Resting allows the juices to redistribute before slicing.

3. Cook the Onion and Jalapeño

Add the remaining 2 teaspoons of olive oil to the skillet.

Add the sliced onion and chopped jalapeño. Cook for about 4–5 minutes, stirring occasionally, until the onion softens and begins to brown.

Add the minced garlic and cook for about 30 seconds, just until fragrant.

4. Make the Cilantro Sauce

Reduce the heat to medium-low.

Add the salsa, fresh cilantro, lime juice, and hot pepper sauce to the skillet. Stir to combine and cook for about 2 minutes, allowing the flavors to blend.

5. Slice the Beef

Slice the rested flank steak thinly against the grain. Cutting against the grain shortens the muscle fibers and helps keep the beef tender.

Add the sliced beef to the skillet and toss gently with the sauce.

Cook for another 1–2 minutes, just until the beef is warmed through.

6. Assemble the Tacos

Warm the flour tortillas.

Divide the cilantro beef mixture among the tortillas. Top with shredded lettuce, extra salsa, fresh cilantro, and sour cream as desired.

Serve immediately with lime wedges if desired.

Recipe Tips for Success

• Slice against the grain. This is especially important with flank steak and makes a noticeable difference in tenderness.
• Don’t overcook the steak. Flank steak is best cooked quickly and sliced thinly.
• Let the steak rest before slicing. This helps retain its juices.
• Adjust the heat to taste. Leave some jalapeño seeds in if you want a spicier filling.
• Warm the tortillas before serving. Warm tortillas are softer and less likely to crack.
• Use fresh cilantro. Fresh cilantro provides much brighter flavor than dried herbs.

Ingredient Substitutions

• Flank steak: Skirt steak or thinly sliced sirloin can be used.
• Flour tortillas: Corn tortillas are an excellent alternative.
• Olive oil: Avocado or vegetable oil can be used.
• Fresh cilantro: If you don’t enjoy cilantro, fresh parsley can be used, although the flavor will be different.
• Salsa: Use mild, medium, or hot salsa depending on your preference.
• Lime juice: Fresh lemon juice can work in a pinch.

Recipe Variations

Frequently Asked Questions

What is the best way to cut flank steak for tacos?

Always slice flank steak against the grain. Look for the direction of the long muscle fibers and cut perpendicular to them into thin slices.

Can I use another cut of beef?

Yes. Skirt steak, sirloin, or another tender beef steak can work well. Choose a cut that can be cooked quickly and sliced thinly.

Can I make these tacos less spicy?

Absolutely. Use a mild salsa, remove all jalapeño seeds and membranes, and omit or reduce the hot pepper sauce.

Can I use corn tortillas?

Yes. Corn tortillas are a great alternative to flour tortillas and add a slightly different flavor.

Can I prepare the beef ahead of time?

Yes. Cook and slice the beef up to a day ahead and refrigerate it. Reheat it gently with the salsa mixture just before assembling the tacos.

What toppings go well with cilantro beef tacos?

Shredded lettuce, salsa, sour cream, fresh cilantro, avocado, guacamole, diced tomatoes, and shredded cheese are all good choices.
