Once the beef is fully cooked and the sauce has thickened slightly, taste and adjust seasoning if you like. Depending on your barbecue sauce, you may want a pinch of salt, pepper, or an extra spoonful of barbecue sauce for more smokiness.
Serve the calico beans hot, straight from the slow cooker. If the mixture seems a little thin for your liking, leave the lid off and cook on HIGH for an additional 15 to 20 minutes to let some of the liquid evaporate and the sauce thicken.
Use this simple base to fit whatever you have in your pantry. For a more traditional “calico” look, swap one can of pork and beans for a can of drained kidney beans or pinto beans (you’ll still pour at least one full can of pork and beans with its sauce over the raw beef to keep the spirit of the recipe and the headline). If you like a little heat, choose a spicy barbecue sauce or add a pinch of crushed red pepper flakes. You can also use ground turkey or ground pork instead of beef; just keep the same amount and layering method. For extra smokiness, stir in a few slices of cooked, crumbled bacon toward the end of cooking. If you need this to stretch further, add another small can of beans and a splash of water or broth, then taste and bump up the barbecue sauce and brown sugar to keep the flavor balanced. Leftovers freeze well in airtight containers for up to 3 months, making this a great Sunday prep recipe for easy weeknight dinners.
