Ingredients for argentinian steak sauce

Five simple ingredients create this vibrant Argentinian chimichurri sauce for bold, restaurant-quality flavor.

The parsley is non-negotiable here—farmers market or organic grocery store leaves have the brightest flavor. Look for vibrant green, not wilted. Garlic should be fresh, not sprouting, and the red wine vinegar matters too—Bartles & Jaymes or Bragg are solid choices. The olive oil? California avocado or Italian brands add depth. I always grab extra parsley—half goes in the sauce, half gets chopped for garnish later.

No red wine vinegar? White wine vinegar or apple cider vinegar work in a pinch, though flavor differs slightly. Short on parsley? Cilantro or flat-leaf parsley at half the amount can stretch it. The red pepper flakes can be swapped for crushed cayenne at one-third the amount. For a smoother texture, pulse everything in a food processor, but the traditional chunky version is what makes chimichurri special. The salt is crucial—Diamond Crystal dissolves better than table salt.

This sauce keeps beautifully in an airtight jar in the fridge for 5 days, or 3 months frozen. I portion mine into small containers for easy use—perfect for drizzling over steaks or tossing with grilled veggies. The flavors deepen if you let it sit 10 minutes before serving. For a smoky twist, add a pinch of smoked paprika to the finished sauce.

Step-by-step instructions for Argentinian steak sauce

This vibrant chimichurri transforms simple ingredients into a bold, herby sauce perfect for grilled meats.

Place the 1.5 cups of fresh parsley leaves in a food processor or sharp chef's knife. I like to use a food processor for this step—it gives you perfectly fine, even pieces without the mess of chopping by hand. Pulse until you achieve a coarse chop, about the size of large grains of rice. You want enough texture to maintain some bite, but fine enough to blend smoothly.

Add the 6 whole peeled garlic cloves to the food processor. Pulse just until the garlic is minced—you don't want it to turn into a paste. The garlic should be small enough to disappear into the sauce but still retain some definition. If using a knife, chop the garlic finely but not too finely, as it will blend further when mixed with other ingredients.

Transfer the chopped parsley and garlic mixture to a medium bowl. Add the 0.5 cup of red wine vinegar and 0.75 cup of extra-virgin olive oil. I always use a high-quality, fruity olive oil for chimichurri—the flavor difference is noticeable, and it balances the acidity of the vinegar beautifully. Stir well with a wooden spoon or silicone spatula until everything is thoroughly combined.

This is where the sauce begins to come together. The vinegar will start to brighten the parsley's color, and the olive oil will begin to emulsify with the herbs. The mixture should look like a thick, vibrant green paste at this stage. If you're using a food processor, you can pulse everything together at this point for a smoother texture, but I prefer the rustic look of a slightly chunkier sauce.

Add the 1.5 teaspoons of kosher salt and 1 teaspoon of red pepper flakes to the bowl. Stir well to distribute the seasonings evenly. Taste the mixture and adjust the salt or red pepper flakes as needed. Argentinian chimichurri is bold, so don't be shy with the seasoning. The sauce should have a bright, tangy flavor with a hint of heat from the red pepper flakes.

If the sauce is too thick, add 1-2 tablespoons of water or a splash of the red wine vinegar to loosen it. You want a sauce that's thick enough to cling to meat but still drizzle easily. The consistency should be like a loose, herby pesto—thick but not pasty. This sauce is meant to be used immediately, so there's no need to worry about it thickening further over time.

Let the chimichurri rest for 10-15 minutes before serving. This allows the flavors to meld and the oil to fully emulsify with the herbs and vinegar. The sauce will deepen in color and develop a more complex flavor profile. Don't skip this step—it makes a world of difference in the final result.

Serve the chimichurri immediately over grilled steaks, sliced meats, or even as a dip for crusty bread. The vibrant green color and bright, herby flavor will elevate any dish. If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. The flavors will continue to develop, but the texture may thicken slightly. Stir in a splash of water or vinegar to loosen it before using.

Best sauces and condiments for this recipe

Classic Chimichurri

This is the traditional Argentinian sauce we're making today—bright, herby, and packed with fresh parsley and garlic. The key is balancing the red wine vinegar (never sub apple cider) with high-quality extra-virgin olive oil like California avocado or Italian brands.

I always use Bartles & Jaymes red wine vinegar because it has that perfect tang without being harsh. The 1 teaspoon of red pepper flakes adds just enough heat to complement the richness of grilled steak. 🌿

Smoky Chimichurri Twist

For a smoky variation, replace the red pepper flakes with 1 teaspoon smoked paprika and add ½ teaspoon of ground cumin. This version pairs beautifully with flank steak or skirt steak and adds a subtle depth that works well with charred meats.

I like to toast the cumin in a dry pan for 30 seconds before adding it to the sauce for extra aroma. The smoky notes complement the herbaceous parsley perfectly.

Creamy Chimichurri

For a richer texture, stir in 2 tablespoons of sour cream or crème fraîche after the sauce has rested. This creates a luxurious sauce that's perfect for beef tenderloin or ribeye steaks. I recommend using full-fat sour cream to maintain the sauce's body.

The creaminess balances the acidity of the vinegar while keeping the bright parsley flavor intact. This version is ideal for those who prefer a smoother sauce without losing the chimichurri's signature taste. 🥛

Spicy Salsa Criolla

If you want to switch things up entirely, try a salsa criolla instead. Dice 1 cup of ripe tomatoes, ½ red onion, and 1 jalapeño, then mix with ¼ cup of red wine vinegar and ½ cup of olive oil.

This tangy, slightly spicy sauce works wonderfully with grilled lamb chops or empanadas. The tomatoes add a fruity sweetness that contrasts beautifully with the vinegar's acidity. It's a fantastic alternative for those who enjoy a chunkier, tomato-based sauce.

Herb Variations

Don't be afraid to experiment with different herbs! Swap out ½ cup of the parsley for cilantro or flat-leaf parsley for a different flavor profile. You can also add 1 tablespoon of fresh oregano or thyme for a Mediterranean twist.

I've even tried adding 1 teaspoon of fresh basil for a brighter, slightly sweeter note. Just remember, the parsley is the star—don't overpower it with too many other herbs. The goal is to enhance, not replace, the classic chimichurri flavor. ✨
