  1. My hubby loves baked beans. He always picks up cans of them, but I’m sure homemade tastes so much better! Pinned.

      1. Did you soak the beans overnight? I feel like that could be the only thing that could go so wrong in this awesome recipe !

  2. I used two cans of northern beans and one can of red kidney beans. Also used half of a vidalia onion and half of a red onion. Turned out absolutely wonderful. Added just a bit more maple syrup as well. Awesome recipe. Thank you!!!!5 stars

  3. made these yesterday for Father’s day BBQ. I tripled the recipe and there were NONE left. my dad loved them and compared them to my grandma’s, greatest compliment I could get. my son in law, who is beyond a picky eater, had three helpings!!5 stars

    1. Hey, Loretta. I’m guessing you could cook on high for 3-4 hours. But I normally do low and slow for a deeper flavor.

  4. Made these yesterday to take to the cottage and they are so easy and tasty! Definately a keeper recipe; great for any time of the year. I added a couple of tablespoons of hot sauce for a little zip.

  5. Hello, do you have to soak the beans overnight or just drain and rinse. Also, I would like to use turkey bacon…should I precook it before I put it in the crockpot? Thanks!

    1. This recipe uses canned beans, so don’t soak. I don’t use turkey bacon so I can’t recommend if you should cook it first.

  6. Can these be portioned off and frozen. I have been looking for a molasses style of Boston Baked Beans since I lost my recipe a few years ago. But I am alone now and would need to freeze to be beneficial. Please advise.

  7. I’m cooking dry navy beans now. Will add those to the rest of ingredients and pray for the best! I’ll cook all night on low for tomorrow’s bbq.

  8. The Wife and I made 4 # 12 DUTCH OVEN’S Full and had the Whole Family over for Father’s Day Dinner. We had Our Five Adult Couples that is Daughter’s & Son-In-Law’s, 12 Grand Children & 7 Great Grand Children. And the Beans went over with a Big Bang.
    Thank U for the Wonderful Baked Bean Recipe. Very time We make these Beans we will think of U. THANK YOU Again.5 stars

  9. Hi Can you use Canned Navy Beans in this recipe instead of Pinto or Great Northern Beans?? It looks like a great recipe.

    1. We have never used dried beans for this recipe so I couldn’t recommend how many pounds of beans you would need. Maybe two pounds?

  10. The best BB Bean recipe!
    I used dried Great Northern beans, soaked them 12 hours then after adding all the other ingredients I cooked them on low for 12 hours adding a couple of cups of water every so often while they cooked,5 stars

  11. These sound great! I’d love to try them but do have one question… does the bacon get crispy at all putting it in raw, or should I fry it a bit first if that’s my preference?

    1. Hi, Emily. No, fry the bacon first if you want it to be crispy. Just note that it will be cooking in the juices and not stay as crispy.

    1. Hi, Beth. Although I have never tested this try using a dutch oven, cook the bacon, add the onion and saute until soft. Add the remaining ingredients, bring to a boil, cover, and bake at 300 degrees F for about 3-4 hours occasionally stirring until thick and creamy. Watch it closely.
