Key Ingredients & Substitutions
Flank Steak: This cut is great for tacos due to its beefy flavor and ideal texture when cooked. If flank steak isn’t available, skirt steak or sirloin can be used instead.
Olive Oil: It adds richness to the marinade and chimichurri. If you’re looking for a balance of flavor and smoke, use avocado oil instead.
Cilantro: The star of the chimichurri! If you’re not a fan of cilantro, try using fresh basil or parsley to create a different but tasty sauce.
Red Wine Vinegar: It gives the chimichurri a nice acidity. White wine vinegar or apple cider vinegar can work as substitutes if you don’t have red wine vinegar on hand.
Tortillas: I recommend using flour tortillas for a softer bite, but corn tortillas are also a delicious option if you prefer gluten-free!
How Do I Cook Flank Steak Perfectly?
Cooking flank steak can be tricky, but it’s easy when you know the right steps. The key is to cook it quickly over high heat and to slice it properly. Here’s how:
- Let your steak come to room temperature before cooking; about 15-20 minutes is ideal.
- Cook it on a hot skillet or grill, about 4-5 minutes on each side for medium-rare. Use a thermometer to check if it’s 130-135°F.
- After cooking, let it rest for 5-10 minutes. This helps the juices redistribute and keeps it tender.
- Finally, slice against the grain—this shortens the fibers and creates a more tender bite.
Follow these steps, and you’ll have perfectly cooked flank steak every time!
Easy Flank Steak Tacos with Garlicky Cilantro Chimichurri
Ingredients:
For the Flank Steak:
- 1.5 to 2 pounds flank steak
- 2 tablespoons olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon smoked paprika (optional)
- 1/2 teaspoon cumin (optional)
For the Garlicky Cilantro Chimichurri:
- 1 cup fresh cilantro leaves, packed
- 3 tablespoons fresh parsley leaves (optional for balance)
- 3 cloves garlic, minced
- 1 small shallot or 1/4 cup red onion, finely chopped
- 1 small jalapeño, seeded and minced (optional for heat)
- 1/4 cup red wine vinegar
- 1/2 cup extra-virgin olive oil
- 1/2 teaspoon salt, more to taste
- 1/4 teaspoon black pepper
- 1/4 teaspoon crushed red pepper flakes (optional for extra heat)
For the Tacos:
- 8-10 small flour tortillas (or corn tortillas if preferred)
- Lime wedges for serving (optional)
Time Estimate:
This recipe will take about 15-20 minutes to prepare and an additional 10-15 minutes to cook, plus any marinating time if you choose to marinate the steak for 1-2 hours. Overall, expect to spend about 30-40 minutes (or longer if marinating) on this delicious taco night!
Instructions:
1. Prepare the Chimichurri Sauce:
In a food processor or by hand, finely chop the cilantro, parsley (if using), garlic, shallot or onion, and jalapeño. Transfer everything to a mixing bowl and stir in the red wine vinegar, olive oil, salt, black pepper, and crushed red pepper flakes if you want a little heat. Taste and adjust seasoning if needed. Set aside to let the flavors meld together.
2. Marinate the Steak (Optional):
For extra flavor, rub the flank steak with olive oil, salt, black pepper, smoked paprika, and cumin. Allow it to rest at room temperature for about 15-20 minutes. If you have more time, you can marinate it in the fridge for 1-2 hours to really enhance the taste.
3. Cook the Steak:
Heat your grill pan or skillet over medium-high heat. Cook the flank steak for about 4-5 minutes on each side to achieve a medium-rare doneness, depending on the thickness of the steak. You’re aiming for an internal temperature of 130-135°F (54-57°C). If you prefer it more done, adjust the cooking time accordingly.
4. Rest and Slice:
Once cooked, remove the steak from the heat and let it rest for about 5-10 minutes. This resting period allows the juices to redistribute, making the steak more flavorful. After resting, slice the steak thinly against the grain to ensure each bite is tender.
5. Warm the Tortillas:
While the steak is resting, warm the tortillas in a dry skillet over medium heat, or directly over a gas flame if you’re feeling adventurous! Warm them just until they’re pliable and have a few charred spots.
6. Assemble the Tacos:
Take a few slices of the flank steak and place them onto each warmed tortilla. Generously spoon the garlicky cilantro chimichurri over the steak, allowing that vibrant flavor to shine.
7. Serve:
Serve your delicious tacos with lime wedges on the side, perfect for squeezing over the top. Enjoy your meal immediately for the best flavors and texture!
This recipe delivers tender, juicy flank steak paired with a vibrant, herbaceous cilantro chimichurri that brightens up each bite—making it a fantastic choice for a fun and satisfying taco night!
