Grilled Flank Steak with Chimichurri is a dish that captures everything people crave in a backyard meal: smoky char, tender slices of beef, and a bright herb sauce that cuts through richness with freshness. The steak cooks quickly over high heat, forming a flavorful crust while staying juicy inside. Each slice is deeply savory, with a gentle chew that feels satisfying without being heavy.

What truly defines Grilled Flank Steak with Chimichurri is contrast. The beef is robust and meaty, while the chimichurri brings parsley, garlic, olive oil, and vinegar together in a vibrant spoonful that wakes up every bite. The result is balanced and lively, yet grounded in simple ingredients.

Whether prepared for a casual summer dinner or a relaxed gathering, this recipe delivers reliable flavor without complicated steps. It is straightforward cooking with bold, honest results.

Ingredients Overview

Flank steak is the foundation of this recipe. It is a long, flat cut taken from the abdominal muscles of the cow. Because it is lean and full of muscle fibers, it benefits from high-heat cooking and careful slicing against the grain. When prepared properly, flank steak becomes tender and richly flavored.

Olive oil coats the steak lightly before grilling. It promotes browning and helps seasoning adhere to the surface. Kosher salt and freshly ground black pepper are essential for drawing out the natural taste of the beef without masking it.

For the chimichurri, fresh flat-leaf parsley is key. It provides a clean, grassy backbone. Fresh garlic adds sharp depth, while red wine vinegar gives acidity that balances the richness of the steak. Extra-virgin olive oil binds everything into a spoonable sauce. A pinch of red pepper flakes introduces subtle warmth, and a small amount of dried oregano adds earthy character.

If parsley is unavailable, a combination of cilantro and parsley works well. Shallots can replace garlic for a milder profile. Lemon juice may substitute for red wine vinegar, though the flavor will be slightly brighter and less traditional.

Step-by-Step Instructions

Begin by removing the flank steak from the refrigerator about 30 to 40 minutes before grilling. Allowing it to sit at room temperature promotes even cooking. Pat the surface dry with paper towels to remove excess moisture, which helps achieve a proper sear.

Rub both sides lightly with olive oil. Season generously with kosher salt and freshly ground black pepper, pressing the seasoning into the surface so it adheres well.

Preheat a grill to high heat, around 450 to 500°F. Clean and oil the grates to prevent sticking. Place the steak directly over the heat source. Grill for approximately 4 to 5 minutes on the first side without moving it. This allows a crust to form.

Flip the steak using tongs and cook for another 3 to 5 minutes for medium-rare, depending on thickness. The internal temperature should read 130 to 135°F for medium-rare. Avoid overcooking, as flank steak becomes firm and dry if taken too far.

Transfer the steak to a cutting board and tent loosely with foil. Rest for at least 10 minutes. Resting allows juices to redistribute throughout the meat.

While the steak rests, prepare the chimichurri. Finely chop the parsley and garlic by hand for the best texture. Combine them in a bowl with red wine vinegar, olive oil, dried oregano, red pepper flakes, salt, and black pepper. Stir well and let the mixture sit for 10 to 15 minutes so the flavors meld.

To slice the steak, identify the direction of the muscle fibers. Cut thin slices against the grain at a slight angle. This shortens the fibers and creates tenderness in every bite.

Arrange the slices on a serving platter and spoon chimichurri generously over the top. Serve additional sauce on the side.

Common mistakes include skipping the resting period, slicing with the grain, or cooking over low heat. High heat and proper slicing are crucial for tender results.

Tips, Variations & Substitutions

Marinating the flank steak for up to 4 hours in olive oil, garlic, and vinegar can deepen flavor, though it is not required. If marinating, avoid exceeding 8 hours, as too much acid may affect texture.

For a smokier profile, add a small handful of soaked wood chips to a charcoal grill. If cooking indoors, a cast-iron grill pan over high heat works effectively.

To create a spicier chimichurri, increase the red pepper flakes or add a small amount of finely chopped fresh chili. For a milder sauce, reduce the garlic slightly.

If flank steak is unavailable, skirt steak or flat iron steak are suitable alternatives. Both respond well to high heat and quick cooking.

For a lower-sodium option, reduce salt slightly and rely more on herbs and vinegar for flavor balance.

Serving Ideas & Occasions

Grilled Flank Steak with Chimichurri pairs beautifully with grilled vegetables such as zucchini, bell peppers, or asparagus. Roasted potatoes or a simple rice pilaf also complement the bold flavors.

For a lighter plate, serve the sliced steak over arugula with shaved Parmesan and a drizzle of extra chimichurri. The peppery greens balance the richness of the beef.

This dish suits summer gatherings, weekend dinners, or relaxed celebrations. It can also be sliced thinly for sandwiches or tacos, making it versatile for casual entertaining.

A glass of dry red wine or sparkling water with citrus rounds out the meal without overpowering the flavors.

Nutritional & Health Notes

Flank steak is a lean cut of beef that provides high-quality protein, iron, and B vitamins. Protein supports muscle maintenance and overall satiety.

Olive oil contributes heart-friendly monounsaturated fats, while parsley offers small amounts of vitamin K and antioxidants. Garlic contains beneficial plant compounds that add both flavor and nutritional value.

Because this dish is naturally low in carbohydrates, it fits well into balanced eating plans when paired with vegetables or whole grains. Portion control is important, as red meat should be enjoyed in moderation as part of a varied diet.

Grilling allows excess fat to drip away, keeping the preparation lighter compared to pan-frying in additional oil.

FAQs

How do I keep flank steak tender?

Tenderness depends on three factors: high heat, proper resting, and slicing against the grain. Cook the steak quickly over direct heat to form a crust without drying the interior. Remove it from the grill at medium-rare for optimal texture. After resting for at least 10 minutes, locate the muscle fibers running lengthwise and slice perpendicular to them. Cutting against the grain shortens the fibers, which makes each bite easier to chew. Skipping any of these steps can result in a firmer texture.

Can I prepare chimichurri in advance?

Yes, chimichurri can be prepared several hours ahead of time. In fact, allowing it to rest for 1 to 2 hours at room temperature deepens the flavor as the garlic and herbs infuse the oil and vinegar. If making it a day ahead, store it in the refrigerator in an airtight container. Bring it back to room temperature before serving and stir well, as the oil may solidify slightly when chilled. Fresh herbs are most vibrant within 24 hours.

What is the ideal internal temperature for flank steak?

For juicy results, cook flank steak to an internal temperature of 130 to 135°F for medium-rare. If you prefer medium, aim for 140 to 145°F. Use an instant-read thermometer inserted into the thickest portion of the steak. Because flank steak is lean, cooking beyond medium can cause it to become firm and less juicy. Removing the steak slightly below your target temperature allows carryover cooking to finish the process during resting.

Can I cook this recipe without an outdoor grill?

Yes, a cast-iron grill pan or heavy skillet works well indoors. Preheat the pan over high heat until very hot before adding the steak. Cook for similar timing, about 4 to 5 minutes per side for medium-rare, depending on thickness. Proper ventilation is helpful, as high-heat cooking can create smoke. You can also broil the steak in the oven, placing it close to the heating element for a similar charred effect.

How long should flank steak marinate?

If choosing to marinate, 2 to 4 hours is sufficient for flavor development. Avoid exceeding 8 hours, especially with acidic ingredients like vinegar or citrus juice. Extended exposure to acid can affect texture, making the surface slightly mushy. Keep the marinade simple with olive oil, garlic, and a splash of vinegar. Always discard used marinade or boil it thoroughly before serving.

Can I freeze leftover grilled flank steak?

Yes, cooked flank steak freezes well when stored properly. Allow it to cool completely, then wrap tightly in plastic wrap and place in a freezer-safe bag. It can be frozen for up to 2 months. Thaw overnight in the refrigerator before reheating gently in a skillet over low heat. Adding a spoonful of chimichurri during reheating helps restore moisture and flavor.

What dishes can I create with leftovers?

Leftover Grilled Flank Steak with Chimichurri can be sliced thinly for steak sandwiches, folded into quesadillas, or added to grain bowls with roasted vegetables. It also works well in salads or wrapped in warm tortillas with fresh greens. Because the steak is already cooked, reheat briefly to avoid overcooking. The chimichurri can double as a dressing or sandwich spread, adding freshness to every preparation.
