This classic stew/chilli of beans, aromatics, veggies, and seared meats is not too thick or heavy, as some versions can be. Slow baking uncovered creates a crust without relying on breadcrumbs to achieve this. And leftovers are even more amazing!
In a large bowl, cover beans with 3 quarts (3 litres) of water and add 3 tbsp salt. Stir to combine and let sit at room temperature overnight. Drain and rinse beans and set aside.
Transfer to oven and cook, uncovered, until a thin crust forms on top, about 2 hours, adding more water (or stock if you have it) by pouring it carefully down the side of the pot as necessary to keep beans mostly covered.
Return to oven and continue cooking undisturbed until the crust is deep brown and thick, another hour or so, or about 5 to 6 hours total. Serve immediately.
Salt added to the dry beans while soaking helps keep them tender as they cook.
Homemade stock cooked for a long time will naturally have enough gelatin (use my version here, to make up several quarts (litres) to store in the freezer till needed!) Only use the commercial gelatin if you are using purchased stock or if you are concerned that your stock may not have enough gelatin in it.
Duck fat will help impart the rich flavour to all the meats, without the need to purchase duck confit, which may be harder to obtain, or not liked by some members of the family. You can purchase a container of duck fat at most independent butchers. Even larger grocery chains now carry it in the deli or meat aisle. It's worth it, use it! And once you have it, it stores it in the back of the fridge indefinitely!
Make sure the dutch oven or casserole is large enough to hold everything. Ideally it should also be as wide as possible, for the most exposure of gelatin to air! For a great crust! Don't be put off by the time in the oven. It is all about creating the crust. If you find that the beans are cooked through, and the gelatin crust isn't important to you, you can definitely serve this earlier.
Serve this with a bright, crisp green salad to balance out the richness of the dish. Sourdough bread on the side will be great to soak up any juices and broth.
Leftovers can be reheated with some more stock added to them. Overnight the beans will soak up any remaining liquid, causing everything to thicken up. The extra broth will help loosen it all up as it reheats.
