This Homemade Chimichurri Sauce bursts with bold, herbaceous flavor. Fresh parsley, cilantro, garlic, and jalapeño blended with tangy vinegar and rich oil for the ultimate Argentine-inspired condiment. Traditionally served with grilled steak, it’s also incredible on chicken, shrimp, roasted vegetables, or even as a zesty marinade. Vibrant, spicy, and aromatic, this sauce adds life to any dish and keeps beautifully in the fridge for days.
