The most decadent slow cooker mac and cheese recipe filled with incredible flavors but made simply in a crock pot. Easy to walk away from while cooking but not while eating. It's one of the best slow cooker recipes ever!
Prepare inside of your slow cooker with a non stick spray coating all parts.
Next add macaroni, all cheeses, and both milks to the slow cooker and stir together to combine. Once thoroughly mixed, turn on slow cooker and cook for 3 hours on high or 4 hours on low.
When 25 minutes are left for cooking the macaroni, stir in the final ingredients and allow to completely cook.
Finally add butter to a skillet on medium heat and allow to melt. Next add panko crumbs and cook to golden brown color. Sprinkle toasted crumbs over macaroni and cheese and serve.
