Chimichurri Flank Steak Recipe

Nothing beats the vibrant, fresh flavors of a perfectly cooked steak topped with a herbaceous punch of sauce. This Chimichurri Flank Steak Recipe brings together juicy, tender beef and a zesty chimichurri that makes every bite sing—trust me, it’s a total crowd-pleaser that’s easier than it looks.

Ingredients You’ll Need

I love how these simple, fresh ingredients come together to create a sauce that’s vibrant but never overpowering. Using fresh herbs and good-quality steak makes all the difference here.

• Flank steak: Look for a piece that’s about 1 ½ to 2 pounds—this cut is lean and flavorful but needs careful slicing against the grain for tenderness.
• Fresh garlic: Fresh is key here; it gives the sauce that punchy aroma and flavor you won’t get from powder or pre-minced.
• Fresh parsley: I usually grab flat-leaf parsley for its bright, clean taste.
• Fresh cilantro: This adds a fresh, slightly citrusy note—if you’re not a fan, you can tweak the amounts or omit it (see variations!).
• Avocado oil: A neutral oil with a high smoke point makes searing the steak perfect without burning.
• Fresh lemon juice: Adds sharp acidity that balances the richness of the meat and oil.
• Salt: Simple but essential for seasoning the steak and sauce just right.

Variations

Feel free to make this chimichurri flank steak recipe your own—I’ve played around with herbs and heat levels to keep it fresh for every season and pallet.

• Herb swap: I once swapped cilantro for oregano and added a pinch of red pepper flakes, which gave the sauce a warm kick without overpowering the steak’s flavor.
• Heat it up: If you like spicy, toss in some chopped fresh jalapeño or a splash of hot sauce into the chimichurri.
• Vegan chimichurri: I’ve made the sauce without steak before—perfect over grilled portobello caps or roasted vegetables for a meat-free twist.
• Different cuts: While flank steak is my go-to, skirt steak works beautifully with this sauce too and cooks up just as quickly.

How to Make Chimichurri Flank Steak Recipe

Step 1: Whip Up That Fresh Chimichurri Sauce

Start by pulsing peeled garlic in a food processor until finely minced—that aroma alone always gets me excited. Then add your fresh parsley and cilantro, pulsing again until finely chopped. Add in the oil, lemon juice, and salt, pulsing a few more times until everything’s nicely combined but still has a bit of texture. Set your fresh sauce aside and let those flavors mingle while you prep the steak.

Step 2: Marinate Your Flank Steak for Maximum Flavor

Here’s a trick I learned: if your flank steak is too big to handle easily, cut it in half crosswise—just make sure you cut against the grain! That makes slicing tender later so it doesn’t get chewy. Place the steak pieces in a large dish or zip-top bag, then pour about a third of your chimichurri over them. I like to toss the steak around to coat it evenly and then let it marinate for at least 30 minutes, but honestly, an hour or two works wonders if you have the time.

Step 3: Sear Your Steak to Juicy Perfection

Heat a sturdy cast iron skillet over medium-high heat for a good 3 minutes—patience here creates that great sear. Remove the steak from the marinade and scrape off any excess; you don’t want it soggy when hitting the hot pan. I always pat mine dry with a paper towel, then sprinkle a little salt right before cooking. Add avocado oil to the skillet—1 tablespoon if you’re cooking two smaller pieces, or 2 tablespoons for one larger steak. Wait until the oil shimmers but isn’t smoking (this is key to avoid bitter burnt flavors) and place your steak in carefully with tongs.

Cook each side 3 to 4 minutes depending on thickness and your preferred doneness. I find 3 minutes per side usually nails medium-rare for thicker cuts; thinner steaks may need less time. After searing, let the steak rest on a cutting board for 5 minutes—this helps the juices settle, making it super juicy when you slice into it.

Step 4: Slice Against the Grain and Serve with Extra Chimichurri

When your steak has rested, slice it into half-inch thick pieces—always cut against the grain to keep the meat tender and easy to chew. Arrange the slices on a platter and generously spoon more of that herby chimichurri on top. I like to serve extra chimichurri on the side so everyone can add as much as they want. Enjoy the fresh, zesty burst with the rich beef—it’s divine every time!

How to Serve Chimichurri Flank Steak Recipe

Garnishes

I usually sprinkle chopped fresh parsley over the top for a bright, fresh look and a little extra herbal pop, plus a wedge of lemon on the side for anyone wanting a bit more zing. Sometimes crushed red pepper flakes add a nice subtle heat, especially if I’m serving it for dinner guests who like a bit of spice.

Side Dishes

My favorite sides to pair with this are simple: crispy roasted potatoes or a fresh green salad with a lemon vinaigrette. I’ve also served it with grilled veggies like asparagus or zucchini, which soak up the chimichurri beautifully. And of course, freshly baked crusty bread is perfect for mopping up every last bit of that sauce.

Creative Ways to Present

For special occasions, I like to arrange the sliced flank steak over a bed of garlic mashed potatoes and drizzle with chimichurri right before serving. It makes for a gorgeous, colorful plate that impresses without much effort. Another time, I made chimichurri steak tacos with thin slices tucked into warm corn tortillas topped with pickled onions—so fun and tasty!

Make Ahead and Storage

Storing Leftovers

I usually place leftover steak slices in an airtight container and store them in the fridge for up to 3 days. I keep the chimichurri sauce separate in a small jar to keep flavors fresh and bright.

Freezing

Freezing cooked flank steak works well—I slice the steak first and freeze the slices in a freezer-safe bag with some chimichurri sauce. When thawed, the steak retains most of its juiciness, but to be honest, fresh is always best for that bright chimichurri flavor.

Reheating

To reheat, I prefer gently warming steak slices in a skillet over low heat with a splash of broth or water to keep them moist—avoid microwaving if you want to preserve tenderness. Add fresh chimichurri after reheating to refresh flavors.
