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

- 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.
