When prepared correctly, it remains tender while staying lower in fat compared to ribeye or strip steak.
The chimichurri sauce adds its own benefits. Fresh parsley and cilantro are rich in antioxidants, vitamin C, and vitamin K, supporting immune health and digestion.

Step by Step Preparation
Preparing the Chimichurri Sauce
Start by placing the garlic cloves into the bowl of a food processor. Pulse several times until the garlic is finely minced but not paste like. Scrape down the sides to ensure even texture.
Add the fresh parsley and cilantro to the processor. Pulse again until the herbs are finely chopped and evenly mixed with the garlic. Avoid overprocessing, as the sauce should remain textured rather than smooth.
Pour in the olive oil slowly, followed by the fresh lemon juice. Add the dried oregano, crushed red pepper flakes, salt, and any optional additions such as lemon zest or black pepper. Pulse until all ingredients are well combined and emulsified. Taste and adjust seasoning if needed. Transfer the chimichurri to a bowl and set aside at room temperature to allow flavors to develop.
Marinating the Flank Steak
If the flank steak is very large or uneven in shape, slice it in half against the grain to make it easier to cook evenly. Place the steak pieces into a large baking dish or sealable food storage bag.
Spoon about one third cup of the chimichurri sauce over the steak. Turn the steak several times to coat all surfaces evenly. Cover the dish or seal the bag and refrigerate for at least 30 minutes. For deeper flavor, marinate for up to 2 hours. Avoid longer marination, as the acidity can affect texture.
Searing the Steak
Remove the steak from the refrigerator about 10 minutes before cooking to allow it to come closer to room temperature. Heat a large cast iron skillet over medium high heat for about 3 minutes until fully heated.
Remove the steak from the marinade and gently scrape off excess sauce. Pat the steak dry with paper towels to promote proper browning. Lightly season with salt on both sides.
Add avocado oil to the hot skillet. Use 1 tablespoon if cooking smaller pieces or 2 tablespoons if cooking a full steak. Heat until the oil shimmers.
Carefully place the steak into the skillet using long tongs. Cook undisturbed for 3 to 4 minutes on the first side depending on thickness. Flip and cook for another 3 to 4 minutes for medium doneness. Adjust time for preferred doneness.
Remove the steak from the skillet and transfer to a cutting board. Let it rest for 5 minutes to allow juices to redistribute.
Slicing and Serving
After resting, use a sharp knife to slice the steak into 0.5 inch thick slices against the grain. Arrange slices on a serving platter and spoon fresh chimichurri sauce over the top. Serve with additional sauce on the side.
Storage and Make Ahead Tips
Flank Steak with Chimichurri stores well when handled properly. Allow cooked steak to cool completely before storing. Place steak slices in an airtight container and refrigerate for up to 3 days. Store chimichurri sauce separately to preserve freshness and color.
For best results, reheat steak gently in a skillet over low heat or enjoy it cold in salads or wraps. Avoid microwaving for long periods, as it can toughen the meat.
Chimichurri sauce can be prepared up to 2 days in advance and stored in the refrigerator. Bring it to room temperature before serving and stir well to recombine the oil and herbs.
Freezing is not recommended for chimichurri due to texture changes, but cooked flank steak may be frozen for up to 2 months if tightly wrapped.
Variations and Substitutions
Flank Steak with Chimichurri is highly adaptable. You can substitute skirt steak or flat iron steak using the same method. For a milder sauce, reduce crushed red pepper or replace it with smoked paprika.
Herb variations work well. Try using fresh oregano instead of dried, or add a small amount of fresh mint for a cooling effect. Lime juice can replace lemon juice for a slightly sweeter acidity.
For grilling, cook the steak over direct high heat for similar timing. Let it rest and slice the same way. Chimichurri pairs equally well with grilled vegetables or roasted potatoes.
Tips and Tricks for Perfect Results
Always slice flank steak against the grain to shorten muscle fibers and ensure tenderness. Look closely at the direction of the grain before cutting.
Use high heat and a dry surface when searing to achieve a flavorful crust. Moisture is the enemy of browning, so pat the steak dry.
Let the steak rest after cooking. This step is essential for juicy results and should never be skipped.
Taste chimichurri before serving. Adjust salt and acidity to suit your preference. A balanced sauce should be bright, savory, and slightly spicy.
If using a thermometer, aim for internal temperatures of
Medium rare: 130 to 140 F
Medium: 140 to 150 F
Medium well: 150 to 160 F
Well done: 160 to 170 F
Notes on Doneness and Texture
Thickness affects cooking time significantly. Thicker cuts require slightly longer searing, while thinner cuts cook quickly and should be monitored closely.
If you do not have a thermometer, use the touch test. Gently press the center of the steak with tongs. Softer texture indicates rarer doneness, while firmer texture indicates more doneness.
Avoid pressing the steak while cooking, as this releases juices and reduces tenderness.
Serving Suggestions
Serve Flank Steak with Chimichurri alongside roasted vegetables, mashed potatoes, or a simple green salad. It also works well sliced thin for sandwiches, grain bowls, or wraps.
