Step‑by‑Step Instructions for Flank Steak with Chimichurri Sauce
Step 1: Marinate the Steak
Begin by using a fork to puncture the flank steak, allowing the marinade to penetrate deeply for optimal flavor. In a bowl, whisk together the soy sauce, olive oil, Worcestershire sauce, honey, minced garlic, lemon juice, lemon zest, oregano, and red pepper flakes. Place the steak in the marinade, ensuring it’s completely covered. Refrigerate for a minimum of 2 hours, or up to 24 hours for maximum tenderness, flipping halfway if needed.
Step 2: Prepare Chimichurri
While the steak marinates, prepare the basil cilantro chimichurri. In a mixing bowl, combine the chopped basil, cilantro, minced garlic, olive oil, red wine vinegar, lemon juice, chopped Fresno chile, and a pinch of salt. Stir well until all ingredients are evenly mixed. Let the chimichurri sit for at least 15 minutes to allow the flavors to meld, creating a vibrant and zesty topping for your flank steak.
Step 3: Grill the Steak
Preheat your grill to medium-high heat, ensuring it’s hot enough to achieve a beautiful sear. Once preheated, place the marinated flank steak on the grill and cook for approximately 12 minutes. Rotate the steak halfway through cooking for even grill marks. Aim for an internal temperature of 130°F for medium-rare using a meat thermometer, which will guarantee a juicy, tender result.
Step 4: Rest and Slice the Steak
After grilling, remove the flank steak from the grill and allow it to rest for 10 minutes on a cutting board. This resting period is crucial as it helps the juices redistribute, ensuring each bite is flavorful and moist. Once rested, slice the steak against the grain into thin strips; this technique maximizes tenderness and creates perfectly bite-sized pieces for serving.
Step 5: Serve
To serve, arrange the sliced flank steak on a platter and generously drizzle the chimichurri sauce over the top. This flavorful marinated flank steak with chimichurri sauce not only looks stunning but also promises a delicious blend of savory and zesty flavors. Pair it with your favorite sides, and enjoy a delightful summer meal!

Flank Steak with Chimichurri Recipe FAQs
How do I select the best flank steak for this recipe?
When choosing flank steak, look for a cut that has a bright red color and minimal dark spots or discoloration. Ideally, the meat should be well-marbled, which contributes to tenderness and flavor. If you can, choose grass-fed beef, as it typically has a more robust taste.
How should I store leftover cooked flank steak and chimichurri?
Cooked flank steak can be stored in an airtight container in the refrigerator for up to 3 days. It’s best to store the chimichurri sauce separately to preserve its vibrant flavor. If you need longer storage, wrap the steak tightly in plastic wrap and freeze it for up to 3 months.
Can I freeze the flank steak with chimichurri?
Absolutely! For freezing, first allow the cooked steak to cool. Then, wrap it tightly in plastic wrap and place it in a freezer-safe bag or container. For chimichurri, consider freezing it in ice cube trays for easy portioning. Just remember to label and date both for future reference, and enjoy within 3 months for the best flavor.
What should I do if my steak is tough after cooking?
If you find your steak is tough, it might be due to slicing against the grain. Always cut across the grain of the meat for the most tender slices. Additionally, make sure to marinate the steak long enough; at least 2 hours, but ideally up to 24 hours, will help tenderize it. A meat thermometer is crucial, too; aim for 130°F for a perfectly tender steak.
Are there any dietary considerations I should keep in mind?
When preparing this flank steak with chimichurri, consider any allergies, especially related to garlic or soy sauce. For a gluten-free option, substitute the low sodium soy sauce with tamari. If serving to pets, avoid giving them steak since cooked meat can sometimes be hard on their digestive systems, especially if it’s seasoned.
