Ingredients
- For the Flank steak Marinade:
- 1.5 pounds flank steak,trimmed of excess fat
- 1/4 cup extra virgin olive oil
- 3 cloves garlic,finely minced
- 2 tablespoons soy sauce (or tamari for gluten-free)
- 1 tablespoon freshly squeezed lime juice
- 1 teaspoon ground cumin
- 1 teaspoon smoked paprika
- 1/2 teaspoon freshly ground black pepper
- 1 teaspoon crushed red pepper flakes (optional,for heat)
- For the Zesty Chimichurri sauce:
- 1 cup fresh flat-leaf parsley,finely chopped
- 1/2 cup fresh cilantro,finely chopped
- 4 cloves garlic,minced
- 1 small shallot,minced
- 1/3 cup red wine vinegar
- 3/4 cup extra virgin olive oil
- 1 teaspoon dried oregano
- 1 teaspoon crushed red pepper flakes
- Salt and freshly ground black pepper to taste
Instructions
- Prepare the Marinade: in a medium bowl,whisk together extra virgin olive oil,garlic,soy sauce,lime juice,cumin,smoked paprika,black pepper,and red pepper flakes until fully blended.
- Marinate the Flank Steak: Place the trimmed flank steak in a large zip-top bag or shallow dish. Pour the marinade over the steak,ensuring an even coat. Seal and refrigerate for at least 4 hours, ideally overnight, to tenderize and infuse bold flavors.
- Make the Chimichurri Sauce: While the steak marinates, combine parsley, cilantro, garlic, shallot, red wine vinegar, olive oil, oregano, and crushed red pepper flakes in a glass jar or bowl. Stir thoroughly, season with salt and pepper, then cover and refrigerate for flavors to meld at least 1 hour before serving.
- Preheat Your Grill: set your grill for medium-high heat, cleaning the grates thoroughly and oiling lightly to prevent sticking.
- Grill the Flank Steak: Remove steak from marinade, shaking off excess. grill for about 5-6 minutes per side for medium-rare, adjusting time based on thickness. Use a meat thermometer to aim for 130-135°F (54-57°C).
- Rest the Meat: Transfer steak to a cutting board,loosely tent with foil,and rest for 10 minutes. This step locks in juices and keeps the meat tender.
- Slice and Serve: Using a sharp knife, slice flank steak thinly against the grain to maximize tenderness. Plate and generously spoon zesty chimichurri sauce over the top for a bright contrast to the smoky meat.
Tips for Success
- Marinate Thoroughly: Flank steak is lean and benefits hugely from overnight soaking in the marinade to break down fibers and boost flavor.
- Rest Before Slicing: Always allow the steak to rest after grilling to redistribute juices for a juicier bite.
- Chop Chimichurri Fresh: For vibrant color and flavor, chop herbs finely and avoid over-blending – the sauce should be chunky, not puréed.
- Grill Marks Matter: Place the steak diagonally on the grill grates and rotate after 2-3 minutes per side to achieve stunning crosshatch marks.
- Substitutions: if fresh cilantro isn’t preferred, increase parsley and add a touch of fresh oregano for herbal balance.
- Make Ahead: Chimichurri tastes even better the next day; prepare it up to 2 days in advance and store in an airtight container.
