Slow Cooker Boston Baked Beans are the ideal side dish for summer grilling season and they could not be any easier to make from scratch.

It probably isn’t a huge surprise that my husband who was born and raised in Boston adores baked beans, along with hermit cookie bars and baked scallops with panko. Of course, he would be perfectly happy re-heating them from a can but that’s no fun. Slow Cooker Boston Baked Beans are extremely easy to make, and delicious!

When I realized how easy these were to make, I kicked myself for not making them more often. But truth be told, my Aunt Patsy is the Baked Beans Queen of our family and serves them at almost every warm-weather gathering. She would never make a batch of beans without massive amounts of smoky and delicious bacon. I’m not anti-bacon, I just rarely have it sitting around in our fridge. To give these beans that unmistakable smoky flavor we crave, I rely on my BFF smoked paprika.

Ingredients

Labeled ingredients for Boston baked beans.

  • Molasses: Gives the beans the unmistakable rich, sweetness of Boston baked beans.
  • Worcestershire sauce: Full of umami, sweet, and savory flavor.
  • Sweet & savory spices: Brown sugar, smoked paprika, salt, and pepper add a mix of smoky, rich, and sweet tastes to the beans.
  • Mustard: A little peppery and vinegary in flavor.
  • Ketchup: Acts as a mild tomato base for the sauce.
  • Vinegar: White balsamic vinegar or apple cider vinegar adds some needed acidity.

Liz’s Notes

Beans can be made up to two days in advance. In fact, the flavor develops over time as it sits in the fridge. Canned beans work fine too if you don’t have dried beans on hand.
Cook time may vary based on the age/freshness of the dried beans.
Omit Worcestershire sauce to make recipe vegan.

    I made these baked beans. I soaked them overnight, cooked in slow cooker following the recipe.after 6 hours on high beans were still very crunchy. Left them in the slow cooker until after noon, the next day, on low. They were finally at the right consistency. IF I try this particular recipe again I will precooked the beans. These were fresh beans.

      Hi Valerie,

      I’m so sorry this didn’t work out for you! That’s quite surprising the beans were still crunchy – I’ve never experienced that after soaking overnight and six hours of cooking. Are you sure the beans were fresh?

        I used to have similar issues with chickpeas, I’d cook and cook and cook them and they would never get soft. Then a very kind person tipped me off to adding some baking soda to the soaking water. It never fails, and it actually even considerably shortens “traditional” cooking times for me (I have not tried it for the slow cooker yet but I will very soon!). Hope this helps :)

    I really loved the flavours in this recipe; however, you state in the recipe that dried beans can be substituted for canned beans. I made this recipe with canned beans, following all the directions, and ended up with soup. I had to remove everything from the slow cooker (after 5 hours on high) and transfer it to the stovetop and simmer away all the liquid for about an hour. Then I was reading through the comments to see if this happened to other people, and noticed a comment from the author that this recipe was never tested with canned beans. Don’t write in the recipe then that canned beans can be substituted! I also agree with one of the other commenters, normal Worcestershire sauce is NOT vegetarian, unless you find a brand without anchovies.

      Hi Jack, Canned beans work great – I use them all the time! Out of curiosity, did you still add in all the water even though you used canned (cooked) beans? The water is only added to cook the dry beans. :)

    What I care most about is that eating this does weight gain? Because I’m on a diet.

      Hi Standa, You will only gain weight if you eat more calories than you burn in a day and since I don’t know what other activities you’re doing or foods you’re eating I can’t tell you.

    Worcestershire sauce is not the difference between vegetarian and vegan; it is the difference between vegetarian and NOT vegetarian! Please omit “vegetarian” from your title or omit “Worcestershire sauce” from your recipe. Thanks!

      Hi Deb – You can leave it out to make it vegetarian! I’ll make a note of that in the recipe!

        Thanks Liz. I made these tonight and my whole family lived them. No soaking just cooked on high for about 8-9 hours and added extra water at the end. I’m vegan and used a vegan Worcestershire sauce no problem. I was happy to stumble onto your recipe!!

            I ommited the Worcestershire sauce and added 1 tbsp Bragg’s Liquid Aminos, natural soy alternative. I also ommited table salt and used Himalayan Pink Salt (but not as much as usual, because of the soy alternative.)
            I am cooking now for lunch tomorrow. I will let you know the response.
            Also, I doubled the amount of beans for a large gathering at my church luncheon.
            Thanks for the recipe…♡♡

    This looks like a fabulous recipe, and I love that it doesn’t have a ton of sugar in it! I am thinking of making several batches for a graduation party — have you ever tried freezing them? I was hoping to make a couple batches a week and freeze them until the party later in June.

        I freeze the beans I make all the time because I am the only one in my family who is vegan. We have a food saver so I freeze them in 2 or 3 portion sizes and then I have enough for a couple of days when I defrost. Beans freeze great, doesn’t even change the texture of them.

    Love this recipe and am gathering ingredients! But I did have a question… So you just soak the beans overnight but you do not begin cooking them until they are mixed with the other ingredients? The beans will cook soft enough?
    Thanks!!

    1. Liz DellaCroce Avatar
      Liz DellaCroce

      Yes exactly! You cook once they are mixed with the others!!

    I really really wanted these to be great!! But 13 hours in the slow cooker and they beans are still crunchy! Crunchy baked beans are not good :(

    1. Liz DellaCroce Avatar
      Liz DellaCroce

      Hi Shannon – I’m so sorry these didn’t turn out for you! Do you know if your beans were expired? I know that often the cook time can vary if the beans aren’t fresh. We buy ours from a local farmers so we know they were fresh and I wonder if that is part of the reason yours didn’t cook in 13 hours. So sorry!!

        The age of the beans do not matter if you pressure-can them before adding to recipes. Store bought are never as good as home cooked. Use extreme caution to cook outside of jars. Over frothing would glog the vent pipe and cause a hazard. Tender and delicious never tasted so good. Thanks for sharing. Cant wait ti taste them.

      I found this recipe when searching for a vegetarian recipe, Spanish paprika is the answer to that lovely smokiness of baked beans, and you can use a vegetarian Worchester sire sauce. However I disagree with Joanne above, this recipe does have a ton of sugar “diabetes anyone “. I have reduced the sugar in this recipe from two thirds of a cup, to 2 tablespoons of molasses, I also cut the amount of beans in half, but keeping all the other ingredients the same. I use a non-prepared mustard, something that has a nice strong bite of real mustard, I also eliminated the vinegar because these types of mustards tend to be more vinegary, plus the vinegar in the ketchup.
      I have found that soaking your beans overnight results in a tough skin no matter how long you cook them. I simmer my beans in plenty of freshwater until tender but not done, drain the water and replace with 2 1/2 cups of fresh boiling water, and all the other ingredients. I cook them in the oven at 350° uncovered until the liquids cooks down to a nice thick deliciously delicious sauce. Do not salted beans until this last cooking phase in the oven, that also tends to make your beans tough and takes longer to cook them. Not sure how this would all work in a slow cooker, probably would be just fine.

    I doubled the recipe and the flavor is promising, but 5 hours later on high and I have soup. I transferred to a pot and am hoping to steam off some fluid although, it’s hard to imagine the sauce getting thick and caramelized with the beans. It seemed like a lot of water to add, but I was trusting the recipe! Maybe I’ll try again with half the water. It’s nice to see a recipe that works with raw beans. Everyone uses canned these days!

      Oh no – soup??? Yikes!! One thing I’ve noticed is that everyones beans are a little different in cook time based on how old they are. Keep me posted how it turned out!

    If we are using canned beans, do we still have to soak overnight? Or no?

    Hello, and thank you for this fabulous recipe!

    The first time I tried this, I used the “sprouted beans” that I got from Costco (they say no soaking required and are a mix). Those beans never cook, and the bag was fresh. We had to eat them crunchy in the end, but the flavor from your recipe was excellent.

    I am making this again with pinto beans. I’m wondering about the water content, though. My package says to fill the slow cooker to 1-2 inches of water over the top of the beans. This ends up being over 3 cups of water per lb of beans. Does this sound correct to you? If I add all of the other ingredients, then have to drain my beans, I lose a lot of the flavor. But, if I don’t add enough water (and I’m cooking 2lbs), my beans will burn and not cook. Oh, the stress! ha ha

    Anyway, I am super excited to get to eat these beans! The flavor was so delicious that we were willing to eat all of the “not fully cooked” costco beans. The beans done right will be absolute perfection!

    So, as a little side note, I was searching for a recipe for beans that was like what my mother made when I was a kid. Everybody loved her beans, but I could never manage to duplicate them. I saw your recipe posted on facebook and thought it was close enough that I would give it a whirl. This is exactly what I was looking for! My mother added sausage – some big sausage thing that comes in a package in the shape of a U. We’re vegetarian, so don’t want the sausage, of course. This is the recipe, though! This was absolutely the right flavor, and now I understand that what she made must have been “Boston Baked Beans”. Thank you! My life is complete.

      Oh I’m so thrilled to hear this – you have made my day!!! As for the water, I find it varies so much with the beans depending on size and age. Mine were fresh from a local farm so I am wondering if that’s why mine turned out differently. I will be testing again soon. Keep me posted ok? So glad you love the flavor so much!
