This calico bean casserole brings together sweet and tangy baked beans, three kinds of colorful beans, smoky bacon, and ground beef all baked until bubbling and hearty. It is pure comfort food the kind my family requests at every get-together and our table never has leftovers after a Sunday potluck.
I first discovered this at a church potluck and the mix of beans surprised me with so much depth. Over the years my kids started asking for it on chilly nights when only something cozy will do.
