🛒 Ingredients & The “Authentic” Guide
Real Argentinian chimichurri does not use cilantro! While cilantro is delicious, traditional chimichurri relies entirely on parsley and oregano.
- 1 cup Fresh Flat-Leaf Italian Parsley: (Finely chopped. Do not use curly parsley, as it lacks the robust flavor needed for this sauce).
- 4 cloves Fresh Garlic: (Very finely minced. The garlic infuses the oil with a spicy, savory bite).
- 2 tbsp Fresh Oregano: (Finely chopped. If you only have dried oregano, use 1 tablespoon, but fresh is highly recommended!).
- ⅓ cup Extra Virgin Olive Oil: (Use a high-quality, cold-pressed olive oil, as this makes up the entire base of the sauce).
- 2 tbsp Red Wine Vinegar: (This provides the crucial sharp, tangy acidity that cuts through the fat of grilled meats).
- ½ tsp Crushed Red Pepper Flakes: (For that signature subtle heat).
- ½ tsp Sea Salt & ¼ tsp Black Pepper.
🍳 Step-by-Step Masterclass Instructions
Step 1: The “No-Blender” Rule (Crucial!) 🛑
Why shouldn’t you use a food processor or blender? Blending olive oil at high speeds causes it to oxidize and turn bitter. Furthermore, pureeing the parsley turns the sauce into a cloudy, wet smoothie rather than a rustic, steeped oil.
For an authentic chimichurri sauce, you MUST use a sharp chef’s knife!
Step 2: The Fine Chop 🔪
Wash your fresh parsley and oregano and pat them completely bone-dry with a paper towel. (Water is the enemy of this oil-based sauce!). Using your sharpest knife, finely chop the parsley and oregano leaves. Mince your garlic cloves as finely as possible.
Step 3: Mix the Dry Base
In a medium glass or ceramic bowl, combine the chopped parsley, fresh oregano, minced garlic, crushed red pepper flakes, sea salt, and black pepper.
Step 4: The Vinegar “Bloom” 🌿
Pour the 2 tablespoons of red wine vinegar over the herb mixture. Stir well and let it sit for 5 minutes.
The Culinary Secret: Letting the herbs and garlic soak in the vinegar before adding the oil “blooms” the flavors and slightly softens the sharp raw garlic bite!
Step 5: Stream and Steep
Pour the extra virgin olive oil into the bowl and stir gently to combine.
You can eat it immediately, but for the absolute best flavor, cover the bowl and let it sit at room temperature for at least 30 to 60 minutes before serving. This allows the garlic and herbs to slowly steep and infuse their flavors deep into the olive oil!

🥩 4 Genius Ways To Serve Chimichurri
- Grilled Steak: The classic! Spoon it generously over sliced flank steak, skirt steak, or ribeye.
- Chicken Marinade: Toss raw chicken breasts in half the sauce, grill them, and use the remaining sauce for serving.
- Roasted Vegetables: Drizzle over hot roasted potatoes, carrots, or cauliflower right out of the oven.
- Breakfast Eggs: Spoon a tiny bit over your morning fried eggs for an instant flavor explosion!
🔒 Storage Instructions
- Refrigerator Storage: Store your chimichurri in an airtight glass mason jar in the fridge for up to 1 week.
- Note: The olive oil will solidify in the cold fridge! This is completely normal. Simply take the jar out 30 minutes before your meal to let the oil come back to liquid room temperature, and give it a good stir.
- Freezing: You can freeze leftover chimichurri in silicone ice cube trays. Pop a frozen cube into hot pasta or soup all winter long!
