This bean pie is a traditional Muslim recipe made with canned navy beans, evaporated milk, and sugar. It's similar to pumpkin pie but not as sweet.
Preheat the oven to 450 degrees F (230 degrees C). Place each pie pastry into a 9-inch pie pan.
Place navy beans and evaporated milk into a food processor. Add sugar, melted butter, eggs, egg yolks, flour, vanilla, cinnamon, and nutmeg; pulse a few times, then process until smooth, about 1 minute. Pour mixture into the prepared pie crusts.
Bake in the preheated oven for 15 minutes, then reduce heat to 350 degrees F (175 degrees C) and bake until filling is set and crust is golden brown, about 35 more minutes.
Remove from the oven and let cool for 1 hour before slicing.
