Sometimes it isn’t super fun to eat plain ol’ leftovers, but one leftover that is good again and again is mashed potatoes. And instead of simply reheating, add some elbow macaroni and a ton of cheese, bake in the oven and serve up a decadent combination of deliciousness: mashed potato mac ‘n’ cheese. One part of this is store-bought, the other part is made from leftovers and everything comes together in a dish of indulgence. And if the creamy cheesiness isn’t enough to satisfy you, then the browned cheese topping should be the “icing on the cake,” as they say.

We love the addition of crisped chopped bacon; the salty bite adds savoriness and texture, and really when does adding bacon ever NOT work! This is a real “stick to your ribs” casserole, and one that may require taking a little walk after, but the indulgence is totally worth it. A dish like this comes round only once or twice a year, so dig in and enjoy all of the gooey cheesy potato-y goodness!
