Ingredients

Instructions

  • Rinse and sort dried beans. Remove any discolored or broken beans and any pebbles.
  • Place beans in a large bowl, cover with cold water. Let sit overnight.
  • Pour beans and soaking liquid into a pan and bring to a boil over medium heat, reduce heat and simmer for 1-2 hours until tender.
  • Drain beans and reserve liquid.
  • Spray a 3 quart baking dish with a non-stick cooking spray. Add half of the beans, then add half the bacon and half of the onions on top.
  • Add another layer of remaining beans, bacon and onions.
  • In a medium saucepan, add brown sugar, molasses, ketchup, mustard, Worcestershire sauce and garlic powder. Stir and bring to a boil, over medium heat, stirring frequently.
  • Pour molasses mixture over the beans along with enough reserved liquid to just cover the beans.
  • Cover with aluminum foil and bake in preheated 325 degree oven for 1 ½ hours, remove foil and continue to bake for 1 ½ - 2 hours longer, checking every half hour and adding additional reserved liquid, if needed, so beans do not dry out.

Notes

  • Don’t skip the overnight soak—it softens the beans and helps them cook evenly. 
  • As the beans bake, keep an eye on the liquid level. Add more reserved bean water as needed to keep them moist and saucy.
  • Stick to the lower temp and longer baking time. It’s what gives these from-scratch baked beans their classic texture and flavor—totally worth the wait!
