Cream of mushroom soup is no stranger to the holiday dinner table -- it most often appears in the classic favorite green bean casserole. But topping beans isn't the only way you can incorporate this soup into holiday side dishes. Everyone expects it to show up in casserole, so why not change it up?
Cream of mushroom soup and just one onion can add a lot of flavor to otherwise bland mashed potatoes. When you boil the potatoes, add a small onion, cut into wedges, to the water to infuse some of its flavor. Then, mash the potatoes with cream (or milk), a little bit of butter and a can of cream of mushroom soup. You'll get a super creamy mixture that's got a great flavor -- something a little out of the ordinary.
But what if not everyone in your family is a mushroom fan? No problem. Just make regular mashed potatoes and use the soup as an optional mushroom gravy.
