What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are kitchen staples, but the fresh herbs truly make the chimichurri come alive. You can swap herbs seasonally or based on what you have on hand.

• For the Chimichurri Marinade:
• Fresh flat-leaf parsley, about 1 cup, packed (bright and vibrant flavor)
• Fresh cilantro, ½ cup, packed (optional but adds a nice twist)
• Fresh oregano leaves, 2 tablespoons (earthy depth)
• Garlic cloves, 4 large, minced (the backbone of flavor)
• Red wine vinegar, 3 tablespoons (gives acidity and brightness)
• Extra virgin olive oil, ½ cup (use a good quality one like California Olive Ranch for best taste)
• Red pepper flakes, ½ teaspoon (for a subtle heat)
• Salt, 1 teaspoon (to taste)
• Freshly ground black pepper, ½ teaspoon
• For the Steak:
• Flank steak, 1.5 to 2 pounds (about 700-900 grams), trimmed of excess fat

Substitution Tips: If you don’t have fresh oregano, dried works but use about 1 teaspoon instead. Swap out red wine vinegar with sherry vinegar or apple cider vinegar if needed. For a gluten-free option, this recipe naturally fits as is. If cilantro isn’t your thing, just leave it out or replace with extra parsley.

Equipment Needed

• Sharp chef’s knife and cutting board (for chopping fresh herbs and garlic)
• Mixing bowl (medium size, for making the chimichurri marinade)
• Whisk or fork (to combine the marinade ingredients)
• Resealable plastic bag or shallow dish (for marinating the flank steak)
• Cast iron skillet or grill pan (for searing the steak; I prefer cast iron for that perfect crust)
• Tongs (to flip the steak without piercing it)
• Meat thermometer (highly recommended to check doneness without guesswork)
• Aluminum foil (to tent the steak after cooking and let it rest)

If you don’t have a cast iron skillet, a heavy-bottomed stainless steel pan works, though it may not develop as much crust. For outdoor grilling, a standard grill grate is perfect. I’ve found that maintaining your cast iron well with occasional seasoning keeps it non-stick and ready for steaks like this one.

Preparation Method

1. Prepare the Chimichurri Marinade: Finely chop the parsley, cilantro, and oregano leaves. Mince the garlic cloves really well — you want those flavors to infuse fully. In a medium bowl, whisk together the red wine vinegar, olive oil, red pepper flakes, salt, and black pepper. Stir in the chopped herbs and garlic until well combined. This should take about 10 minutes.
2. Marinate the Steak: Place the flank steak in a large resealable plastic bag or shallow dish. Pour the chimichurri marinade over the steak, making sure it’s coated evenly. Seal the bag or cover the dish and refrigerate for at least 1 hour, ideally 3-4 hours, but no more than 8 hours. Overnight is okay if you’re careful, but the acidity can start “cooking” the meat, so watch the time. (Tip: Flip the bag halfway through to redistribute the marinade.)
3. Bring Steak to Room Temperature: About 30 minutes before cooking, take the steak out of the fridge so it can come to room temperature. This step helps it cook evenly.
4. Preheat Your Cooking Surface: Heat a cast iron skillet or grill pan over medium-high heat until very hot — you want it nearly smoking for that classic sear.
5. Cook the Steak: Remove the steak from the marinade, letting excess drip off (don’t wipe it dry, you want those herbs on there). Place the steak on the hot pan and sear for about 4-5 minutes on one side. Flip and cook another 3-4 minutes for medium-rare (internal temperature around 130°F / 54°C). Adjust time for your preferred doneness.
6. Rest the Steak: Transfer the steak to a cutting board and tent loosely with foil. Rest for 10 minutes — this is crucial so the juices redistribute and stay locked in.
7. Slice and Serve: Slice the steak thinly against the grain (this means cutting across the muscle fibers) for the most tender bites. Spoon some extra chimichurri over the top if you like.

Common pitfalls? Don’t skip the resting step — rushing this leads to dry meat. Also, don’t overcrowd the pan; if it’s too crowded, the steak will steam instead of sear. I’ve learned to trust my meat thermometer over eyeballing doneness every time.

Cooking Tips & Techniques

Cooking a flank steak with chimichurri can feel intimidating, but a few tricks make it foolproof. First, marinating is your friend here — the fresh herbs and acid tenderize and flavor the meat deeply. Don’t rush this step; even 60 minutes makes a noticeable difference.

When searing, high heat is key. I’ve burned a few steaks by turning the heat too low, which dries out the meat and kills that beautiful crust. Patience matters; let the steak sit untouched while it sears to get those brown bits that are pure flavor.

Another tip: slicing against the grain isn’t just a fancy term. It breaks down the muscle fibers, so your steak isn’t tough or chewy. I’ve learned that the hard way when I sliced with the grain and ended up with a jaw workout instead of a tender bite.

Multitasking tip — while the steak rests, use those precious minutes to make a quick side or toss a salad. It’s all about timing and making the most of your kitchen chaos.

Variations & Adaptations

Want to switch things up? Here are some ways to customize this chimichurri marinated flank steak:

• Dietary Adaptation: For a lower-fat version, trim all visible fat and use lean flank steak. The chimichurri keeps it flavorful without extra fat.
• Seasonal Twist: In summer, add diced fresh tomatoes to the chimichurri for a juicy burst. In winter, swap parsley for kale or spinach for a heartier herb base.
• Flavor Variation: Add a splash of smoked paprika or chipotle powder to the chimichurri for a smoky heat. I tried this once during a backyard party and it gave the steak a lovely smoky kick that guests loved.
• Cooking Method: This steak is fantastic on the grill for that outdoor smoky flavor, but you can also broil it in the oven if you don’t have a grill or cast iron skillet.
• Allergen Substitution: If sensitive to vinegar, try lemon juice as the acid component — it brightens the chimichurri just as well.

Serving & Storage Suggestions

This flavorful chimichurri marinated flank steak is best served warm, right after slicing. The fresh herb sauce is vibrant and fresh, so avoid reheating with the chimichurri on top. Instead, store the steak and sauce separately.

Pair it with grilled vegetables, a fresh salad, or even roasted potatoes. For a casual meal, I love serving it alongside warm tortillas and a simple slaw for tacos. It also pairs wonderfully with red wines (think Malbec or Cabernet Sauvignon) or a crisp sparkling water with a squeeze of lime.

To store, wrap the leftover steak tightly in foil or place in an airtight container and refrigerate for up to 3 days. Chimichurri sauce keeps well separately in the fridge for about a week. Reheat the steak gently in a skillet over low heat or in an oven set to 250°F (120°C) until warm. The flavors meld beautifully over time, making leftovers even better.
