  • MAKE-AHEAD

Robert McGrath, the chef and owner of Roaring Fork in Scottsdale, Arizona, often pairs this regional twist on Boston baked beans with corn bread and a salad. You can substitute almost any type of dried beans for the varieties suggested in this recipe. Or, use only one type of bean for a simpler version. The beans need to soak overnight, so plan accordingly.

  1. 1 cup dried kidney beans, picked over and rinsed
  2. 1 cup dried pinto or rattlesnake beans, picked over and rinsed
  3. 1 cup dried black beans, picked over and rinsed
  4. Two 1-pound smoked ham hocks or 1/2 pound lean double-smoked slab bacon cut into 2 pieces
  5. 3 quarts water
  6. 6 cups chicken stock or canned low-sodium broth
  7. 3 medium ancho chiles, stemmed and seeded
  8. 2 tablespoons vegetable oil
  9. 2 large onions, chopped
  10. 4 large jalapeños, seeded and chopped
  11. 2 tablespoons minced garlic
  12. 1/2 cup barbecue sauce
  13. 2 tablespoons tomato paste
  14. Salt and freshly ground pepper
  15. 1 cup butter cracker crumbs
  16. 1/4 pound extra-sharp Cheddar cheese, shredded
  17. Lime wedges, for serving
  1. In a large bowl, soak the kidney and pinto beans in cold water overnight. Soak the black beans overnight in another bowl.
  2. Drain the two bowls of beans separately and transfer each batch to a large saucepan. Add 1 ham hock or piece of bacon to each saucepan. Add 2 quarts of the water and 4 cups of the chicken stock to the pinto and kidney beans. Add the remaining 1 quart of water and 2 cups of chicken stock to the black beans.
  3. Bring the beans in the saucepans to a boil, then cover partially and cook over low heat until they are almost tender, about 1 hour for the kidney and pinto beans and 35 minutes for the black beans. Drain the beans; reserve the kidney and pinto bean cooking liquid. Discard the black bean cooking liquid.
  4. Remove the meat from the ham hocks and shred; reserve the ham hock fat and 1 bone. If using bacon, trim the fat and cut the meat into pieces. Reserve the bacon fat.
  5. Heat a medium cast-iron skillet. Add the ancho chiles and toast, pressing down with a spatula until they are fragrant and blistered, about 30 seconds. Transfer to a heatproof bowl, cover with boiling water and soak until softened, about 15 minutes. Drain and finely chop.
  6. In a large, enameled cast-iron casserole, cook the ham hock fat or bacon fat in the vegetable oil over moderately high heat until the fat is crisp, about 5 minutes. Discard the fat. Add the onions, jalapeños, garlic and ancho chiles and cook over moderate heat, stirring occasionally, until softened, about 8 minutes. Add the reserved ham or bacon meat and cook, stirring until golden, about 3 minutes. Add the barbecue sauce, tomato paste, the reserved ham hock bone and all of the drained beans. Stir in 4 cups of the reserved bean cooking liquid and season with salt and pepper. Cover and cook over moderately low heat, until the beans are tender and the gravy is thick, about 1 1/2 hours longer; add more of the bean cooking liquid if the beans seem dry. Discard the ham hock bone and transfer the beans to a large shallow baking dish or individual crocks.
  7. Preheat the oven to 425°. In a medium bowl, toss the cracker crumbs with the cheese. Sprinkle the mixture over the beans. Bake the gratin for about 25 minutes, or until bubbling and golden. Serve with lime wedges.
Make Ahead The gratin can be prepared through Step 6 and refrigerated overnight. Let return to room temperature before baking.
