Variations on Fully Loaded Mashed Potato Casserole
I flavored these potatoes how I take my baked potatoes, fully loaded. Feel free to swap in your favorite baked potato toppings, like broccoli and cheddar cheese, pico de gallo and Mexican cheese, or caramelized onions, garlic mushrooms, and Swiss cheese.
A loaded baked potato is topped with sour cream, cheddar cheese, bacon, and chives.
My top potato when making mash is Yukon Gold. They are nice and starchy so get really fluffy. Russets or Idaho potatoes are also a good choice but stay away from waxy potatoes like red-skinned or fingerlings.
I prefer to warm the milk or cream before adding to prevent it from curdling from the sudden temperature change.
While both options work, I prefer half-and-half or heavy cream over milk for a richer flavor.
