i find myself with several cans of "vegetarian beans" that are really blah. I would like to make them more like Boston Baked Beans, adding something, especially molasses.
Anyone have any tips to share? I can't eat anything "hot" so the spicy stuff is out.

ketchup - brown sugar - worchestersire sauce -

Cook some onions & bacon then add the beans. Add some barbeque sauce- yum!

Ditto +yellow mustard

All baked beans at my house get brown sugar, molasses and and a little squirt of yellow mustard

all great ideas, thanks!!

Secret...do not tell anyone...with green beans, cornfield beans grandma added "salf pork" found at most meat counters today. slice and fry, taking the rine off the one side and fry it too, but do not eat the rine...when you have turned the salt pork to brown on second side, dump in the beans and let it simmer about 20 minutes.. helps if you have a Dutch oven 'caus the iron wear will flavor it too. There will not be a bean left in the pot.

My mother did the same thing, but used jowl bacon. It's not as salty. She would cut off a chunk, score it and cook it with green or dried beans. Or she would slice it for baked beans laying it across the top of the beans. If you want it to cook faster, cut up the slices with kitchen shears and fry them part of the way. Try using a tablespoon of bacon bits in the canned beans. The type you can buy for salads. I also use crushed red pepper and chicken bouillon. I use the bouillon in every kind of beans I cook in addition to bacon. It adds a lot of flavor. Yum, this is making me want to cook beans today.

I'm assuming you're talking about Pork and Beans without the pork? Many, many years ago in home ec class our teacher gave us this recipe and I've used it frequently:
one can beans
about 2 teaspoons mustard
a couple of tablespoons of brown sugar (depends on how sweet you like them)
about a fourth cup chopped onions
a good sized dash of worcestershire sauce
enough ketchup to make it red again (maybe a half cup or more)
a tablespoon or so of vinegar
bake at 350 degrees for about 45 minutes.
You can add bacon bits or top the casserole with slices of bacon if you wish. Add diced garlic if you like that flavor.

My secret - add cinnamon. Shhhhhhhhh.
