This hearty and flavorful soup transforms leftover turkey into a comforting meal. It combines tender sweet potatoes, protein-rich black beans, and aromatic spices like cumin and oregano, all brightened by fresh lime juice. A perfect way to utilize holiday leftovers, offering a nutritious and satisfying dish.
For a robust flavor base, ensure you properly caramelize the diced onion and celery before adding other ingredients; this builds depth. Cut sweet potatoes into uniform 1/2-inch pieces to ensure even cooking. Since you're using leftover turkey, add it towards the final 10-15 minutes of simmering to prevent it from becoming dry and stringy. The black bean liquid is crucial for thickening the soup and enhancing its earthy flavor, so do not drain. Finish with fresh lime juice off the heat to brighten the soup and balance the richness; adjust salt and pepper to taste at the very end. Using New Mexico chile powder and Mexican oregano will offer a more authentic and nuanced flavor profile.
