Ingredients & Why They Work

The magic of this Chimichurri Flank Steak Recipe lies in simple, fresh ingredients that balance rich and bright flavors. Picking quality steak and fresh herbs really make a huge difference, so shop smart and choose the best you can find.

• Flank steak: This cut is lean but flavorful, and when sliced thinly against the grain, it’s incredibly tender.
• Fresh garlic: Adds a zesty kick that’s essential to authentic chimichurri.
• Fresh parsley: Brightens the sauce with mild herbal notes; always opt for fresh over dried.
• Fresh cilantro: Gives the chimichurri an earthy, citrusy lift that pairs perfectly with the steak.
• Avocado oil: A neutral, high smoke point oil ideal for searing steak and blending the chimichurri ingredients.
• Fresh lemon juice: Injects acidity that balances the richness of the steak and oil.
• Salt: Enhances all the natural flavors in the steak and sauce; don’t skip it!

Tweak to Your Taste

I love how this recipe gives you room to play around. For example, sometimes I swap cilantro for more parsley when folks at my table aren’t cilantro fans, and it still tastes fantastic. Don’t hesitate to adjust seasoning or herbs based on what you love most!

• Mild Version: Use less garlic or swap lemon juice for red wine vinegar for a gentler sourness. I did this once for my garlic-sensitive cousin, and everyone still raved.
• Spicy Kick: Add a pinch of crushed red pepper or a fresh chopped chili to the chimichurri for heat. I find it gives the sauce a fun edge without overpowering.
• Herb Swap: Dabbling with oregano or mint instead of cilantro can add interesting flavors. Try it when you want a fresh twist.

Step-by-Step: How I Make Chimichurri Flank Steak Recipe

Step 1: Whip Up That Vibrant Chimichurri Sauce

The chimichurri is what takes this recipe to the next level—it’s bright, herby, and garlic-forward. I like to pulse fresh garlic first in my food processor, then add parsley and cilantro to get everything finely chopped but still with some texture. Pour in avocado oil and fresh lemon juice last so they emulsify right in. Set it aside so the flavors mingle while you prep the steak—it’s worth the wait!

Step 2: Marinate the Flank Steak Like a Pro

If your flank steak is a big hunk, I usually cut it in half against the grain — trust me, slicing against the grain is key for tenderness and easy eating. Then I massage about a third of the chimichurri onto each piece and let it soak up those flavors for at least 30 minutes, but up to a couple hours. If you’re pressed for time, half an hour will still do the trick. I never skip this step because the marinade tenderizes and infuses the steak perfectly.

Step 3: Sear to Juicy, Flavorful Perfection

Get your cast iron skillet screaming hot — about 3 minutes on medium-high heat. Pull the steak from the marinade, scrape off extra sauce (too much moisture will steam instead of sear the meat), then pat it dry and lightly salt. I add avocado oil to the pan; if you have two pieces, 1 tablespoon is enough, otherwise 2 tablespoons for one whole steak. When the oil’s shimmering but not smoking, in goes the steak. Cook 3-4 minutes per side depending on thickness (I’ll share exact cooking times below). Then, rest your steak for 5 minutes before slicing.

Step 4: Slice and Serve with Love

Slice against the grain into half-inch strips—it really makes all the difference in tenderness here. Lay your slices on a serving platter and smother them with fresh chimichurri sauce. I like to serve extra sauce on the side because, well, can you really have too much? Trust me, everyone’s pouring it on.

How to Serve Chimichurri Flank Steak Recipe

Garnishes

I like sprinkling chopped fresh parsley or a few cilantro leaves on top for a vibrant, fresh look and an extra pop of herbal flavor. Lemon wedges on the side are always a winner too—you can add a squeeze of freshness right at the table.

Side Dishes

This steak pairs wonderfully with grilled veggies like asparagus or bell peppers, creamy mashed potatoes, or even a crisp green salad. One of my favorite combos is a simple roasted potato and arugula salad with shaved Parmesan—keeps things light but hearty.

Creative Ways to Present

For a party, I’ve served this sliced flank steak on toasted baguette slices with chimichurri as little crostini appetizers — always a crowd-pleaser. Or try rolling thin slices into wraps with crunchy slaw and extra chimichurri for casual bites that look fancy.

Make Ahead and Storage

Storing Leftovers

Leftover chimichurri steak stores beautifully in an airtight container in the fridge for up to 3 days. I usually slice the steak first, separate the sauce, and keep them covered separately to preserve freshness and texture.

Freezing

If you want to freeze leftovers, slice the steak and put it in a freezer-safe bag with a bit of chimichurri to keep it moist. I’ve found this works well for up to 2 months; just thaw overnight in the fridge before reheating.

Reheating

To reheat, I gently warm the steak slices with a drizzle of chimichurri in a skillet over medium-low heat—just enough to warm without overcooking. Microwaving works too but can dry out the meat if you’re not careful.
