Ingredients & Why They Work
For this recipe, fresh, high-quality ingredients really make a difference. When you grab your flank steak, look for a nice even thickness for consistent cooking. And for the chimichurri, fresh herbs and freshly squeezed lemon juice brighten up every bite.
- Flank Steak: This cut is lean and flavorful, and when marinated and sliced right, it’s incredibly tender.
- Fresh Garlic: Adds pungent depth to the chimichurri sauce, balancing the acidity beautifully.
- Fresh Parsley: The herbaceous backbone of the sauce, lending freshness and color.
- Fresh Cilantro: Adds a subtle citrusy note that complements the parsley.
- Avocado Oil: Perfect for both the sauce and searing the steak because of its high smoke point and mild flavor.
- Fresh Lemon Juice: Provides a bright, zesty kick that wakes up all the other flavors.
- Red Wine Vinegar: Offers acidity and a slight tang that balances the richness of the steak.
- Dried Oregano: Gives the sauce a warm, earthy undertone, evoking classic Argentinian flavors.
- Salt: Essential for seasoning and bringing out all those fresh ingredients’ natural flavors.
Make It Your Way
The beauty of this Crispy Chimichurri Flank Steak Recipe is how adaptable it is! Whether you want to highlight fresh herbs, adjust the heat, or tweak the marinade, don’t hesitate to make it truly yours.
- Herb Twist: I love swapping out fresh cilantro for more parsley or adding a handful of mint for a bright, refreshing spin. It gives the chimichurri a slightly different but just as delicious vibe.
- Heat It Up: For an extra kick, toss in a pinch of red pepper flakes or a diced fresh chili when making the sauce. It elevates the flavor without overpowering the steak’s natural richness.
- Acid Swap: If you prefer a milder tang, substituting lemon juice with orange juice adds a subtle sweetness, balancing the herbs and garlic beautifully.
- Alternative Cuts: If flank steak isn’t available, skirt steak works wonderfully with this method and marinades just as beautifully for crispy, flavorful results.
- Oil Options: While avocado oil gives great searing potential and a mild flavor, you can use extra-virgin olive oil for a traditional touch that enhances the sauce’s depth.
Step-by-Step: How I Make Crispy Chimichurri Flank Steak Recipe
Step 1: Whip Up That Fresh Chimichurri Sauce
Start by adding peeled garlic cloves to your food processor and giving them a quick pulse until minced. Then toss in fresh parsley and cilantro and pulse again until they’re finely chopped. Pour in avocado oil, fresh lemon juice, red wine vinegar, dried oregano, and salt. Pulse everything together until the sauce comes together smooth and vibrant. Set this bright sauce aside — it’s the heart of your Crispy Chimichurri Flank Steak Recipe!
Step 2: Marinate the Steak for Deep Flavor
If your flank steak is large or can’t fit in your skillet whole, slice it against the grain into two pieces. This is key for tenderness — cutting perpendicular to muscle fibers makes all the difference. Place the steak pieces in a baking dish or zip-top bag, pour ⅓ cup of your chimichurri sauce over them, and turn to coat evenly. Marinate for a minimum of 30 minutes in the fridge, but I find 1 to 2 hours really lets those flavors soak in.
Step 3: Heat Up Your Skillet
Grab a large cast iron skillet and heat it over medium-high for about 3 minutes. The pan needs to be hot enough to create that beautiful sear but not smoking. For two steak pieces, add 1 tablespoon of avocado oil and let it shimmer. For one larger piece, double it to 2 tablespoons of oil. You’re aiming for a hot, shimmering surface ready for the steak to hit it.
Step 4: Pat Dry and Salt the Steak
Pull the steak out of the marinade and scrape off any excess sauce to avoid burning. Use paper towels to pat it dry — this step is crucial for that crispy crust. Lightly sprinkle the steak with salt to season just before cooking. This seasoning combined with the marinade sets the stage for a perfectly balanced flavor.
Step 5: Sear to Your Desired Doneness
Carefully place the steak in the hot skillet with long tongs. Cook for 3 to 4 minutes per side, depending on thickness and how you like it cooked. For thicker cuts, 3 minutes per side gives you a succulent medium-rare; thinner cuts take about 2½ minutes per side. Keep an eye on the sear — you want a golden-brown crust with just the right amount of crispiness. Adjust time based on your preference, checking the steak’s doneness with a meat thermometer if you have one.
Step 6: Let It Rest and Slice
After cooking, remove the steak and let it rest on a cutting board for 5 minutes to let the juices redistribute. This resting step is essential for juicy, tender results. If you split your steak into two pieces, repeat the searing process with the second piece while the first rests. Once rested, slice the steak into ½ inch strips against the grain — this ensures each bite is tender.
Step 7: Serve with a Generous Drizzle of Chimichurri
Arrange those perfect steak slices on a platter, then spoon fresh chimichurri sauce generously over the top. Don’t be shy with the sauce — its fresh, zesty herb flavor is what elevates this dish to the next level. Serve extra chimichurri on the side so everyone can add as much as they like. You’re now ready to enjoy your own crispy, flavorful masterpiece!
Top Tip
Mastering the Crispy Chimichurri Flank Steak Recipe is all about attention to detail. These little tips elevate your meal from good to unforgettable.
- Marinate Just Right: From experience, letting the steak soak in the chimichurri for 1 to 2 hours really deepens the flavor without risking a mushy texture.
- Dry Before Searing: I used to rush this step, but patting the steak dry before it hits the skillet ensures that perfect crispy crust without steaming.
- Sear Hot & Quick: Heating your cast iron skillet for a full 3 minutes before adding oil guarantees that satisfying sizzle and beautiful browning.
- Cut Against the Grain: A common pitfall is slicing with the grain, which makes steak tough. I always take the extra moment to identify and cut perpendicular for tenderness every time.
How to Serve Crispy Chimichurri Flank Steak Recipe
Garnishes
Fresh herbs like extra parsley or cilantro on top add a bright pop. Thin lemon wedges on the side invite a final spritz of citrus, lifting every bite. A sprinkle of flaky sea salt just before serving enhances the steak’s natural flavor beautifully.
Side Dishes
Pair it with oven-roasted potatoes or a crisp green salad for a fresh balance. Creamy mashed cauliflower or grilled asparagus complements the Argentinian-inspired chimichurri flavor perfectly. You could also serve alongside fluffy rice or crusty bread to soak up all that delicious sauce.
Make Ahead and Storage
Storing Leftovers
Store any leftover steak tightly wrapped or in an airtight container in the refrigerator. It will keep well for up to 3 days while retaining most of its flavor and tenderness.
Freezing
If you want to freeze the steak, slice it first and place in a freezer-safe bag or container. Freeze for up to 2 months. Thaw overnight in the fridge before reheating to preserve texture.
Reheating
Reheat gently in a skillet over medium-low heat with a splash of water or broth to prevent drying out, flipping once until warmed through. Avoid high heat to keep the steak tender.
Frequently Asked Questions:

Ingredients
For the Steak
- 1 ½ – 2 pounds flank steak
For the Chimichurri Sauce
- 2 tablespoons fresh garlic, peeled
- ½ cup fresh parsley
- ¼ cup fresh cilantro
- 1 cup avocado oil
- ¼ cup fresh lemon juice
- 1 tablespoon red wine vinegar
- 1 tablespoon dried oregano
- ½ tablespoon salt, plus more to taste
Instructions
- Prepare Chimichurri Sauce: In a food processor, add the peeled garlic and pulse until minced. Add fresh parsley and cilantro and pulse until finely chopped. Add the avocado oil, lemon juice, red wine vinegar, dried oregano, and salt. Pulse until all ingredients are well combined into a smooth sauce. Set aside.
- Marinate the Steak: If necessary, cut the flank steak against the grain into two pieces to fit your skillet. Place the steak(s) in a large baking dish or a plastic food storage bag. Pour ⅓ cup of the chimichurri sauce over the steak and turn to coat evenly. Marinate for at least 30 minutes, preferably 1 to 2 hours in the refrigerator.
- Preheat Skillet: Heat a large cast iron skillet over medium-high heat for about 3 minutes until hot.
- Prepare the Steak for Cooking: Remove the steak from the marinade and scrape off any excess sauce. Pat dry with paper towels and sprinkle lightly with salt.
- Cook the Steak: For two pieces, heat 1 tablespoon of avocado oil in the skillet until shimmering but not smoking. For one larger piece, use 2 tablespoons of avocado oil. Using long tongs, carefully place the steak in the skillet. Cook for 3 to 4 minutes per side depending on thickness and desired doneness (3 minutes per side for medium-rare thicker cut, or 2 ½ minutes for thinner cuts). Adjust time to your preference.
- Rest the Steak: Remove the steak from the skillet and place on a cutting board. Let it rest for 5 minutes to redistribute juices. Repeat cooking for the second piece if split.
- Slice and Serve: After resting, slice the steak into ½ inch strips against the grain. Arrange the slices on a serving platter and spoon fresh chimichurri sauce over the top. Serve additional chimichurri on the side.
Notes
- Cutting flank steak against the grain helps ensure tenderness. Look for the long muscle fibers and slice perpendicular to them.
- Marinating longer than 2 hours can enhance flavor but avoid over-marinating to prevent mushy texture.
- Use a meat thermometer to check doneness: medium-rare is 130–140°F, medium 140–150°F.
- If you don’t have a thermometer, use the touch test by gently pressing the center of the steak with tongs for firmness.
- You can substitute red wine vinegar with apple cider vinegar if needed.
- This recipe works well with other cuts like skirt steak if flank is unavailable.
