Red Iguana's signature mole is a complex sauce built from dozens of ingredients—chiles, spices, chocolate, and nuts—simmered together to create layers of depth that unfold across the palate. The kitchen treats mole as the centerpiece rather than a supporting player, pairing it with tender chicken or other proteins that let the sauce shine. The sauce strikes a balance between richness and brightness, with a subtle sweetness that doesn't overwhelm the savory base. Food writers and local diners consistently point to the mole program as the reason Red Iguana has built its reputation as Utah's premier Mexican restaurant.
