A bright, herby, and garlicky Argentine-style sauce that features a unique vinegar bloom trick to ensure a vibrant, professional-grade flavor every time.
In a small bowl, stir together the 1 teaspoon dried oregano, 1 teaspoon hot pepper flakes, and 1/4 cup red wine vinegar.
Let it sit for 10 minutes to allow the vinegar to become more fragrant and the dried herbs to soften.
Chop the green base
Add 1 cup chopped parsley, 1 cup chopped cilantro, 1/2 onion, 5 cloves garlic, 1 teaspoon coarse salt, and 1 teaspoon freshly ground black pepper to the food processor.
Pulse just a few times until the mixture is rustic and juicy, ensuring you still see distinct little flecks of herbs and onion rather than a puree.
Stream in the oil, then rest
With short pulses, slowly pour in the 1/2 cup extra-virgin olive oil and stop immediately once the sauce looks evenly glossy and loose.
Spoon the chimichurri into a jar, cover, and refrigerate for about 2 hours to let the sharp aromatics mellow and the flavors meld together.
Notes
Pro Tip: Pulse the onion, garlic, and herbs first before adding the oil to ensure the aromatics mince cleanly without creating an unwanted emulsion.Serving Tip: Serve the sauce at room temperature by letting it sit out for 20 minutes before your meal. This allows the olive oil to loosen and the herbal aroma to bloom.Storage & Safety: Store in an airtight glass jar for up to 7 days in the refrigerator. Always keep raw garlic in oil refrigerated to ensure food safety.Texture Secret: For the most vibrant color and rustic texture, use short pulse bursts to avoid bruising the herbs, which can lead to a dull or metallic taste.Nutrition information is estimated based on common ingredients and serving sizes and may vary.
