Argentine-American Chimichurri
(chee-mee-CHOO-ree)
MEAL PREP
This sauce is proof that a strict elimination protocol doesn’t mean eating dry, flavorless protein for a month. The undisputed king of the Argentine asado, chimichurri is a bright, punchy, herbaceous sauce built to cut right through the richness of grilled meats. Traditional recipes rely on nightshades and black pepper for heat, but we can engineer that same sharp bite by letting raw garlic macerate in high-quality red wine vinegar. Step away from the food processor—blending tears the cellular structure to shreds, resulting in a bitter, oxidized paste. Taking five minutes to chop the herbs by hand keeps the sauce rustic, loose, and vibrant all week long.
Ingredients
- fresh flat-leaf Italian parsley1 large bunch
- garlic4 med cloves
- dried oregano2 tbsp
- red wine vinegar1/3 cup
- extra-virgin olive oil1/2 cup
- fine sea salt3/4 tsp
- fresh lemon juice1 tbsp
Method
- 01
Chop the parsley finely by hand.
Use your sharpest chef's knife to chop the parsley into tiny green confetti, avoiding mashing or bruising the leaves into a paste. Transfer the chopped herbs to a glass jar or ceramic bowl.
- 02
Macerate the aromatics.
Add the minced garlic, dried oregano, red wine vinegar, and sea salt to the jar, stirring well to combine. Let this mixture sit for 5 minutes without oil so the acid can lightly cook the raw garlic, mellowing its harshness while extracting a deep, spicy flavor to replace the missing chili flakes.
- 03
Emulsify with oil.
Pour the extra-virgin olive oil over the herb mixture, adding the optional lemon juice if using, and stir vigorously with a fork to combine.
- 04
Let the sauce rest at room temperature.
Walk away for at least 30 minutes before serving. This inactive resting time allows the dried oregano to rehydrate and the flavors to bloom and meld cohesively.
Notes
Why this swap? Ají molido and black pepper.
Authentic Argentine chimichurri utilizes ají molido (crushed red pepper flakes) and black pepper, both of which are strict Core-AIP exclusions due to their potential to irritate the gut lining. We rebuild the sauce's characteristic bite by leaning heavily into the sharpness of raw garlic and the punchy acidity of red wine vinegar.
Why this swap? Sunflower oil.
Native Argentine recipes often call for neutral sunflower or corn oil, but industrial seed oils are strictly prohibited on the protocol due to their inflammatory fatty-acid profiles. Extra-virgin olive oil is a powerful, anti-inflammatory fat that adds a slightly peppery background note, helping mask the absence of the eliminated spices.
Glass matters.
Always mix and store this sauce in a glass jar or ceramic bowl. Heavy concentrations of acid and raw garlic can react with metal mixing bowls, giving the sauce an unpleasant, metallic aftertaste.
Storage and serving.
Store in an airtight glass jar in the refrigerator for up to a week. Olive oil will naturally solidify in the cold; simply let the jar sit at room temperature for 15 minutes before serving, or run the sealed jar under warm tap water to loosen the oil.
