In this guide, you’ll learn how to make Argentine chimichurri the traditional way, plus tips, variations, serving ideas, and cultural background that make this sauce so beloved across South America.
What Is Chimichurri?
Chimichurri is a fresh herb sauce that originated in Argentina and Uruguay. It’s most famously served with grilled meats from an asado (Argentine barbecue), but its uses go far beyond steak.
Traditional chimichurri sauce is made with:
- Fresh parsley
- Garlic
- Olive oil
- Vinegar
- Dried oregano
- Red pepper flakes
- Salt and pepper
There are two main styles:
- Chimichurri Verde (Green) – The classic parsley-based version (this recipe)
- Chimichurri Rojo (Red) – Includes paprika, tomatoes, or red peppers
This green version is the most iconic and widely used, especially as a chimichurri for steak.
Why This Is an Authentic Chimichurri Recipe
Many modern versions add cilantro, lemon juice, or blend everything into a smooth puree. While delicious, those are variations — not traditional.
This authentic chimichurri recipe stays true to Argentine roots:
✔ Hand-chopped herbs for texture
✔ Red wine vinegar instead of lemon
✔ Dried oregano (not fresh)
✔ No cilantro
✔ No blending into a paste
The texture should be loose and spoonable, not thick like pesto.
Ingredients
- 1 cup fresh flat-leaf parsley, very finely chopped
- 4 cloves garlic, minced to a paste
- 2 tablespoons dried oregano
- 1 teaspoon red chili flakes (adjust to taste)
- ½ teaspoon coarse salt (or to taste)
- ¼ teaspoon freshly ground black pepper
- 2 tablespoons red wine vinegar
- ½ cup extra virgin olive oil
- 1–2 tablespoons warm water (optional, to loosen)
Instructions
- Prep the herbs
Wash and completely dry the parsley. Finely chop by hand until very small but not mushy. Avoid using a food processor, which can bruise the herbs and make the sauce bitter. - Mince the garlic
Chop garlic cloves, then sprinkle with a pinch of salt and use the side of a knife to mash into a smooth paste. This helps distribute the flavor evenly. - Combine dry ingredients
In a medium bowl, mix chopped parsley, garlic paste, dried oregano, red chili flakes, salt, and black pepper. - Add vinegar
Pour in the red wine vinegar and stir well. Let this sit for 5 minutes to allow the flavors to bloom. - Add olive oil
Slowly stir in the olive oil until fully combined. The sauce should look glossy and loose, not thick. - Adjust texture
If it seems too thick, stir in 1–2 tablespoons of warm water for a more traditional, spoonable consistency. - Rest before serving
Let the chimichurri sit at room temperature for at least 20 minutes before serving. This allows the flavors to fully develop.
What Does Chimichurri Taste Like?
Homemade chimichurri is:
- Fresh and grassy from parsley
- Bold and savory from garlic
- Tangy from vinegar
- Slightly spicy from chili flakes
- Smooth and rich from olive oil
It cuts through fatty meats beautifully, which is why chimichurri for steak is such a classic pairing.
Tips for the Best Homemade Chimichurri
1. Chop, Don’t Blend
Blending makes it pasty. Hand-chopping keeps it authentic and gives better texture.
2. Use Flat-Leaf Parsley
Curly parsley lacks the same depth of flavor and can taste grassy.
3. Let It Rest
Freshly mixed chimichurri tastes good. After 30 minutes? Incredible.
4. Don’t Skip the Vinegar
Red wine vinegar provides the signature tang that balances the oil and herbs.
5. Taste Before Serving
After resting, adjust salt, vinegar, or chili flakes to your preference.
Variations (Still Delicious!)
While this is an authentic chimichurri recipe, here are popular variations:
Spicier Chimichurri
Add extra red chili flakes or a finely minced fresh red chili.
Smoky Chimichurri
Add ½ teaspoon smoked paprika for a subtle smoky depth.
Lemon Chimichurri
Replace half the vinegar with fresh lemon juice for a citrusy twist.
Cilantro Chimichurri (Not Traditional)
Substitute half the parsley with cilantro for a brighter, more tropical flavor.
How to Use Chimichurri Sauce
This chimichurri sauce is unbelievably versatile.
Chimichurri for Steak
Spoon generously over grilled ribeye, flank steak, or sirloin. The acidity balances the richness of the meat.
With Chicken
Drizzle over grilled or roasted chicken thighs or breasts.
On Seafood
Try it with grilled shrimp, salmon, or white fish.
Over Vegetables
Perfect on roasted potatoes, carrots, cauliflower, or grilled zucchini.
As a Marinade
Use half the sauce to marinate meat and reserve the rest for serving.
Sandwich Spread
Spread onto crusty bread with grilled meat or vegetables.
Salad Dressing Boost
Whisk a spoonful into extra olive oil and vinegar for a bold dressing.
Storage Tips
- Store in an airtight container in the refrigerator for up to 5 days
- Bring to room temperature before serving (olive oil solidifies when cold)
- Stir well before using
Pro Tip: The flavor gets even better after a few hours.
Chimichurri vs Pesto
People often compare chimichurri to pesto, but they’re very different.
| Chimichurri | Pesto |
|---|---|
| Parsley-based | Basil-based |
| Vinegar acidity | No vinegar |
| Loose texture | Thick paste |
| No cheese | Contains Parmesan |
| No nuts | Contains pine nuts |
Chimichurri is brighter and sharper, designed to cut through grilled meats.
Cultural Background: The Heart of Argentine Asado
In Argentina, chimichurri is a staple at asado, a traditional barbecue that’s as much about gathering as it is about food. Large cuts of beef are grilled slowly over wood or charcoal, and chimichurri is served alongside as a table sauce — never cooked on the meat.
Every family has its own version. Some like it spicier, some more garlicky, others extra tangy. But the foundation remains the same: parsley, garlic, oil, vinegar, and oregano.
Frequently Asked Questions
Can I make chimichurri in advance?
Yes! It actually tastes better after resting for a few hours.
Can I freeze chimichurri?
You can, but fresh is best. Herbs lose brightness after freezing.
Why is my chimichurri bitter?
You may have over-processed it in a blender or used too much oregano.
Can I use white vinegar?
Red wine vinegar is traditional and recommended for authentic flavor.
