Ingredients

Instructions

  1. Step 1: Rinse 1 cup dried navy beans and soak in 4 cups water overnight or at least 8 hours until beans double in size.
  2. Step 2: Drain beans and place in a large pot with fresh water to cover by 2 inches. Bring to a boil, then reduce to simmer and cook for 45 minutes until beans are tender but not falling apart.
  3. Step 3: Preheat oven to 300°F. In a skillet over medium heat, cook 4 slices of bacon until crispy, about 6 minutes, then remove and chop into bits, reserving bacon fat.
  4. Step 4: In a mixing bowl, combine 1/3 cup molasses, 2 tbsp brown sugar, 1 tsp dry mustard powder, 1 tsp salt, 1/2 tsp black pepper, 1/4 cup ketchup, and 1 tbsp apple cider vinegar. Stir until smooth.
  5. Step 5: In a 2-quart ovenproof casserole, add the cooked beans and 1 diced medium yellow onion. Pour in the molasses sauce and 1 cup water. Stir gently to combine.
  6. Step 6: Sprinkle the chopped bacon over the top and drizzle 2 tbsp reserved bacon fat.
  7. Step 7: Cover the casserole tightly with foil and bake for 3 hours at 300°F, removing foil in the last 30 minutes to thicken the sauce, until beans are tender and the sauce is sticky and thick.
  8. Step 8: Let cool 10 minutes before serving to allow flavors to meld.
