The aroma of fresh parsley, garlic, and red wine vinegar mingled with the smoky char from the grill, wrapping the backyard in a cozy, inviting scent.

What Ingredients You Will Need

This chimichurri flank steak recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and the fresh herbs can usually be found year-round or substituted if needed.

• Flank Steak: 1.5 to 2 pounds (680-900 g), trimmed of excess fat. Look for a well-marbled piece for best flavor and tenderness.

For the Chimichurri Sauce:

• Fresh parsley: 1 cup tightly packed leaves, roughly chopped (flat-leaf preferred for robust flavor).
• Fresh oregano: 2 tablespoons chopped (or 1 teaspoon dried oregano if fresh isn’t available).
• Garlic: 4 cloves, minced (adds that punch of savory heat).
• Red wine vinegar: 2 tablespoons (for acidity and brightness).
• Extra virgin olive oil: ½ cup (good quality makes a difference here; I recommend California or Spanish brands).
• Crushed red pepper flakes: ¼ teaspoon (adjust based on your heat preference).
• Salt: 1 teaspoon, plus more to season the steak.
• Black pepper: Freshly ground, ½ teaspoon.

Optional but recommended for extra depth:

• Shallot: 1 small, finely minced (adds subtle sweetness).
• Lemon juice: 1 tablespoon, for a fresh citrus lift.

Substitution tips: If you don’t have flank steak, skirt steak works well. For a gluten-free option, all ingredients here are naturally free of gluten. If dairy-free is a concern, no worries—this recipe is naturally dairy-free. Swap the red wine vinegar with apple cider vinegar for a slightly different but still delicious tang. Fresh herbs are best, but if you only have dried, reduce the amount to about one-third.

Equipment Needed

• Grill or Grill Pan: A grill gives the best char, but a cast-iron grill pan works great indoors. I’ve used both, and while the grill adds smokiness, the pan keeps things simple on rainy days.
• Mixing Bowl: For whisking the chimichurri sauce.
• Sharp Knife: Essential for slicing the steak thinly against the grain.
• Cutting Board: A sturdy one with enough space to slice and serve.
• Meat Thermometer (optional): Handy for perfect doneness, especially if you’re new to cooking flank steak.
• Measuring Spoons and Cups: For precise seasoning.

If you don’t own a grill pan, a heavy skillet on medium-high heat can do the trick, but watch out for smoke and be ready to flip quickly. For cleanup, I recommend seasoning your cast iron regularly to keep it non-stick—makes a big difference over time.

Preparation Method

1. Make the Chimichurri Sauce: In a medium bowl, combine the chopped parsley, oregano, minced garlic, red wine vinegar, olive oil, crushed red pepper flakes, salt, black pepper, and minced shallot if using. Whisk until well blended but still slightly textured. Stir in lemon juice last. Set aside at room temperature to let the flavors meld while you prepare the steak. (About 10 minutes)
2. Prepare the Flank Steak: Pat the steak dry with paper towels. Lightly season both sides with salt and black pepper—don’t be shy here, the seasoning penetrates the meat better this way.
3. Marinate: Place the steak in a shallow dish or resealable plastic bag. Pour half of the chimichurri sauce over the steak, turning it to coat evenly. Reserve the other half for serving. Let the steak marinate at room temperature for 30-45 minutes (or up to 2 hours in the fridge if prepping ahead). This allows the acid and herbs to tenderize the meat without overpowering it.
4. Preheat the Grill or Grill Pan: Heat your grill or pan to medium-high, about 400°F (204°C). You want a good sear without burning the herbs on the steak.
5. Cook the Steak: Place the steak on the grill and cook for about 4-5 minutes per side for medium-rare (internal temperature of 130-135°F / 54-57°C). Adjust timing if you prefer it more or less done. A meat thermometer is helpful here. You’ll notice nice grill marks and a slight crust forming—this is flavor developing.
6. Rest the Steak: Transfer the steak to a cutting board and tent loosely with foil. Let it rest for 8-10 minutes. This is key for juicy meat—cutting too soon will cause juices to escape.
7. Slice and Serve: Slice the steak thinly against the grain (this means perpendicular to the lines of muscle fibers) to maximize tenderness. Arrange slices on a platter and spoon the reserved chimichurri sauce over the top. Garnish with extra parsley or red pepper flakes if you like.

Pro tip: While the steak rests, you can toss a simple salad or grill some veggies for a complete meal. I like to serve this with grilled asparagus or a fresh, crunchy slaw.

Cooking Tips & Techniques

Cooking flank steak can feel intimidating, but a few tricks make a big difference. First, marinating is essential—not just for flavor but for tenderizing. The acid in the chimichurri breaks down some of the tougher muscle fibers. Still, don’t marinate too long (over 4 hours) or the meat might get mushy.

When grilling, don’t move the steak around too much. Let it develop a good sear before flipping. That crust is flavor gold. Also, medium-high heat is your friend here—too low and you won’t get that caramelization; too high and you risk burning the herbs and garlic in the marinade.

Resting the steak after cooking is non-negotiable. I’ve learned the hard way—cutting too soon means dry meat. Ten minutes of rest lets the juices redistribute and keeps every bite juicy.

When slicing, always cut against the grain. That means looking closely at the muscle fibers running lengthwise and cutting perpendicular. This shortens the fibers, making each bite easier to chew. It’s a small detail that changes the whole texture.

Lastly, don’t forget to taste your chimichurri before serving—sometimes a splash more vinegar or salt can brighten the sauce just right. Making it ahead lets the flavors marry, but fresh is always best for that vibrant green color and punch.

Variations & Adaptations

This recipe is wonderfully flexible, so feel free to customize based on what you have or prefer:

• Spicy Chimichurri: Add extra crushed red pepper flakes or a diced jalapeño to the sauce for more heat.
• Green Goddess Chimichurri: Swap half the parsley for fresh cilantro for a slightly different herbal note.
• Grilled Veggie Side: Instead of steak, try this chimichurri on grilled portobello mushrooms or zucchini for a vegetarian version that’s just as tasty.
• Oven Method: If grilling isn’t an option, sear the steak in a hot cast iron pan for 2-3 minutes per side, then finish in a 400°F (204°C) oven for 5-7 minutes. Rest and slice as usual.
• Meal Prep: Make the chimichurri sauce ahead and store in the fridge for up to 3 days. Marinate steak overnight for deeper flavor.

I once swapped the parsley for basil and found it gave the sauce a sweeter, almost Italian twist—great if you want to pair the steak with a side like fluffy mini quiches for brunch-style gatherings.

Serving & Storage Suggestions

Serve the chimichurri flank steak warm or at room temperature. It pairs beautifully with grilled or roasted vegetables, crusty bread, or even a simple salad. I like to set the steak slices on a platter with a small bowl of extra chimichurri on the side for guests to spoon as they like.

For gatherings, this recipe shines because you can prepare most of it ahead. The steak can rest covered at room temperature for a little while before slicing, and the sauce tastes even better after sitting.

Leftovers keep well in an airtight container in the fridge for up to 3 days. Reheat gently in a skillet over low heat or eat cold in sandwiches or salads. The flavors develop over time, so sometimes next-day steak with chimichurri is even more vibrant.

If freezing, slice the steak first and store it with sauce separately in freezer-safe bags for up to 2 months. Thaw overnight in the fridge and warm carefully to avoid drying out.

This meal pairs nicely with something bubbly like the sparkling New Year’s sangria or a crisp white wine to cut through the richness of the beef and balance the herbs.
