An elegant green mole made with pistachios, chiles, and fresh herbs. This refined, protein-rich family sauce offers a luxurious, modern twist on traditional Mexican mole preparations.
Toast the pistachios in a dry skillet over medium heat for 3–4 minutes, stirring often, until aromatic and just golden; cool slightly.
In a large saucepan, heat 2 tbsp olive oil over medium heat. Add chopped onion and sauté for 5 minutes until translucent, then add garlic and serrano chiles; cook 2 more minutes, being careful not to brown.
Add torn bread, ground cumin, and half the salt. Stir for 2 minutes to combine, allowing bread to absorb flavors.
Pour in chicken broth and bring just to a simmer, then add pistachios, spinach, cilantro, and parsley. Simmer gently (do not boil) for 10 minutes to meld flavors and preserve the herbs' bright color.
Transfer mixture to a blender and purée until perfectly smooth. Return to pan, season with black pepper and remaining salt. Over low heat, stir and reduce the sauce, uncovered, for 10–15 minutes until thickened to desired consistency.
Taste for seasoning; adjust as desired. Serve warm as a sauce over chicken or roasted vegetables.
