This recipe requires 3 cups of barbecue pork or beef. I generally save some when I smoke a butt in the slow cooker (Slow Cooker Smoked Pork Butt) but you can use some store-bought. This recipe is from Betty Crocker. Because my daughter doesn’t like heat, I leave out the green chiles and use regular Monterey Jack instead of pepper-Jack cheese. The recipe opens in a new tab. Loaded Barbecue Baked Potato Casserole.
