This rustic yet elegant spaghetti dish features tender chicken or duck livers seared with aromatic sage and sweet leeks, then tossed with crisp-tender asparagus and perfectly cooked whole wheat spaghetti. A rich sauce is created by deglazing with white wine and emulsifying with starchy pasta water, finished with a generous shaving of Parmigiano cheese for a hearty and flavorful meal.
The key to this dish is perfectly cooked chicken livers – sear them quickly over high heat to achieve a beautiful crust while keeping the interior tender and pink. Overcooking will render them tough and dry. Blanched asparagus added at the end maintains its vibrant color and crisp-tender texture. The combination of olive oil and butter provides excellent flavor and heat transfer for sautéing. Always reserve plenty of starchy pasta water; it's essential for emulsifying the sauce and creating a silky coating for the spaghetti. Ensure leeks are thoroughly washed, as they can hide grit. A splash of dry white wine or vermouth for deglazing adds a crucial layer of acidity and depth. Finish with freshly shaved Parmigiano for optimal flavor and presentation.
