Settler's Beans

A few years ago, at a school potluck, a coworker named Jan made these beans and gave us the recipe. She called them "Settler's Beans" and when we looked this up online, there are quite a few versions of a recipe called "Old Settler's Beans." We aren't sure why they are called this. What we are sure of, however, is that they were a big hit at our Christmas Eve party and we promised to share our version, so here it is. They are more like chili than baked beans, with sweet, spicy and smoky flavors. This recipe makes about 14 one-cup servings.
Ingredients:1 lb. ground beef1/2 lb. bacon, chopped into 1/2-inch pieces1 medium onion, diced1 28-ounce can country style baked beans1 15.5-ounce can light red beans1 15.5-ounce can dark red beans1 15.5-ounce can black beans1 15.5-ounce can canellini beans1/3 cup brown sugar1/3 cup white sugar1/4 cup ketchup1/4 cup BBQ sauce1 teaspoon chili powder1 tablespoon ground mustard2 tablespoons molassesblack pepper to taste
In a large skillet, brown the ground beef, bacon and onion together. Drain the fat. In a large oven-proof baking dish (we used our beanpot), combine all the beans including the liquid. Stir the meat mixture into the beans. Add all the remaining ingredients and stir well. Cover the baking dish and bake at 350 for one hour.
Note: To make ahead, do not bake. Instead, allow the mixture to cool, then refrigerate overnight. Bake when ready to serve.
