Boston Baked Beans

Summer parties and potlucks were a regular occurrence when I was growing up. I think it was more of an excuse for the adults to get together and drink while the kids babysat each other. At least that’s what’s happening now that I’m older.

Food was always the highlight of any gathering and everyone had THEIR dish that they consistently brought to the party. From potato salad to my favorite Strawberry Pretzel Salad Dessert, the staples were always represented time and time again. Especially the BEST Boston Baked Beans ever. 

I had forgotten about Boston Baked Beans for years until recently when I was cleaning out my recipe box. There, inside the little file folders, were all my relatives favorite recipes. Tucked away and categorized by course, I flipped through the cards like a trip through memory lane until I found the baked beans I remembered from long ago.


  • Navy Beans – Dried beans are used in this recipe so they soak up the sauce intensifying the flavor.
  • Salt Pork – Salt Pork is traditional in Boston Baked Beans. If you can’t find it, pork belly is a good substitute.
  • Onions – Don’t skip the onions. Because they cook so long, they lose the peppery bite and become sweet, caramelized perfection.
  • Brown Sugar – I use light brown sugar for a milder sweetness but dark brown sugar will also work.
  • Molasses – Another non negotiable, the rich, deep flavor of molasses is key to perfect baked beans.

For a full ingredient list and measurements, see the recipe card at the bottom of the post.

What are Boston Baked Beans?

You may know that Boston is also called “Bean Town” and it’s actually the result of a publicity stunt….not because they corner the bean market. BUT Boston Baked Beans did originate in Boston and are, basically, navy beans that are combined with onions, salt pork and a sweet, molasses based sauce. Stewed for hours, these beans are the OG of baked beans.

Now, don’t get me wrong, I have made baked beans in the past but I made BBQ baked beans which take much less time because there’s no presoaking and I added bacon. But they’re just not the same as a traditional Boston Baked Bean recipe because the flavors in a slow cooked baked bean recipe are nothing short of magical. And because the beans are not from a can, the flavor is much more pronounced with each and every bite.

Also, since you’re starting with dry beans….the beans tend to hold up much better and don’t become mushy like in most baked bean recipes. The beans in Boston Baked Beans have a little bite to them and don’t dissolve in the sauce. They’re hearty, sticky sweet and totally addicting.

They do take a bit of time to bake but, as with many slow cooked recipes, your time will be rewarded with each and every single bite you take. You may never buy canned baked beans again. Ever.

How to Make Boston Baked Beans

Old Fashioned Boston Baked Beans are cooked slowly, more like a braise than a bake, to extract maximum flavor from the simple ingredients used in the recipe. You can certainly make a quick Boston Baked Beans recipe using canned beans but trust me when I say….you must at least try the traditional recipe once in your life. You won’t open canned Baked Beans ever again.

  1. Soak your navy beans overnight. Rinse and discard the liquid.
  2. Preheat oven to 350 degrees.
  3. Stir together the molasses, brown sugar, ground mustard, garlic powder, salt, ground cloves, and pepper.
  4. In the bottom of a heatproof casserole or bean pot, layer 1/3 of the onion and 1/3 the salt pork.
  5. Spoon half the beans over the onion and salt pork in an even layer and pour half the sauce over the beans.
  6. Add another layer 1/3 of the onions, 1/3 of the salt pork, the remaining beans and cover with the sauce.
  7. Arrange the remaining onion and salt pork on top of the beans.
  8. Cover and bake for 2 hours. Uncover and continue to bake for an additional hour or until the liquid has started to thicken.

The sauce for Boston Baked Beans is a little looser than most baked bean recipes I’m used to. If you want to thicken the sauce for your beans you can remove 1 cup of the sauce from the cooked beans. Create a slurry with 2 tablespoons cornstarch and 2 tablespoons cold water. Stir the slurry into the reserved cup of sauce until smooth and then return the thickened sauce to the beans. Stir them all together and allow to sit for 10-15 minutes. The sauce will begin to thicken as the beans cool a bit.

What is Salt Pork?

Salt Pork is a salt cured pork usually from the pork belly and has a high fat content. It is used in traditional baked bean recipes and to flavor water for cooking vegetables, as with greens in southern cooking.

Because of it’s high fat content and excess saltiness, you can actually use less salt pork than other types of meats without sacrificing flavor. This is one of those times when Less is More. 

It is generally cooked or seared before using. However, since we are braising our beans for a long period of time, I skipped the precooking of my salt pork and just chopped it into bite size pieces to toss into the dish. This is one of those times when laziness prevails.

Can I substitute bacon for salt pork?

You can definitely substitute bacon for salt pork but just be sure to use a very thick sliced bacon or it will just melt into the sauce due to the long cooking time.

What to Serve with Boston Baked Beans

I love to serve these alongside any type of barbecue because they cut the sweetness of the sauce so well.
