Chimichurri originated in Argentina as a rustic sauce for grilled meats, reflecting the country's strong barbecue (asado) tradition. It combines fresh herbs, garlic, and vinegar to cut through the richness of beef, making it a staple at family gatherings and celebrations.

In the north of Argentina, chimichurri often includes more oregano and red pepper flakes, while in the central Pampas region it leans toward parsley, garlic, and vinegar. Some versions add smoked paprika or use olive oil instead of beef fat.

It is traditionally spooned over grilled steak, chorizo, or chicken, and also offered as a dipping sauce on the side. In some regions it is drizzled on roasted vegetables or used as a marinade for meat before grilling.

Chimichurri is a centerpiece at asado gatherings, which are common for birthdays, national holidays, and family reunions. Its bright flavor complements the communal, slow‑cooked meats that define these celebrations.

Using beef tallow adds a deep, meaty richness that mirrors the flavor of the steak it accompanies, while still delivering the herbaceous brightness of traditional chimichurri. The infused fat also makes the sauce keto‑ and paleo‑friendly.

Common errors include overheating the tallow, which can burn the garlic; over‑blending which can cause the sauce to separate; and adding too much vinegar at once, which overwhelms the herb flavor. Follow the low‑heat infusion and add vinegar gradually.

Low‑heat infusion allows the garlic, thyme, and rosemary to release their aromatics slowly without scorching, creating a nuanced flavor that fully penetrates the fat. Direct melting at high heat would produce a harsher, burnt taste.

Yes, the sauce can be prepared up to two days in advance. Store it in an airtight jar in the refrigerator; bring it to room temperature or gently warm before serving to restore its smooth texture.

The finished chimichurri should be a smooth, glossy emulsion with a vivid green‑gold hue from the herbs and tallow. It should coat the back of a spoon without clumping and have a fragrant, slightly tangy aroma.

When the garlic becomes fragrant and the herbs have softened after 30 minutes of low heat, the tallow has absorbed their flavors. The mixture should not be bubbling; a gentle simmer is sufficient.

The YouTube channel Fallow focuses on creative, ingredient‑driven cooking tutorials that blend classic techniques with modern twists, often highlighting lesser‑used fats and bold flavor pairings for home cooks.

Fallow emphasizes the use of animal‑based fats like beef tallow to deepen flavor, whereas many channels stick to olive oil or butter. This approach brings a richer, more authentic taste to traditional Argentinian dishes such as chimichurri.
