In a large skillet over medium heat, brown the sausage and onion together. Drain off any fat.
Combine all of the beans, sugar, Worcestershire sauce, soup, paste and mustard in a slow cooker.
Add the drained sausage and onions.
Cook on high for 3 hours or on low for 5 hours. With one hour left, sprinkle on ¾ cup crumbled bacon. Then cover and cook the last hour to heat through.
An easy way to get more servings out of this is to add more baked beans. It stretches this savory casserole further without affecting the flavor too much!
You can also not cook the onion with the sausage and just add the raw onion to the slow cooker.
