Loosen Your Belt Mashed Potato Casserole Another Turkey Day Side Dish!

I just made Paula Dean Proud

Two reason you need to make this dish on Thanksgiving for your guests.

1. It tastes awesome

2. Because you can make it ahead of time and it is one less thing to worry about on Turkey Day!

Loosen Your Belt Mashed Potato Casserole

5 lbs peeled potatoes (or be lazy use red skins and don't peel... it's ok! )
1 bulb roasted garlic
1 stick of room temp butter
1 cup heavy cream
1/2 cup sour cream
8 oz cream cheese
3/4 cup cheddar cheese
1/2 cup freshly grated Parmesan cheese
3 slice prosciutto
Salt and pepper to taste
1/4 cup scallions or chives to garnish


Add your peeled potatoes to a big pot of boiling water. Boil until they are fork soft... can't tell you the exact time because well... I'm bad with timers when I'm cooking. Baking I have to use them... cooking is just different....


When they have cooked through strain and add them to your kitchen aid. (if you don't have a kitchen aid go ahead use a masher or potato ricer)

I swear by using my kitchen aid when making a big batch like this... less work for me and they come out lump free.

With your whisk attachment mix potatoes, cream cheese, butter, sour cream and roasted garlic on medium speed. Careful if your bowl is too full you'll get flying potatoes everywhere... I'm known to do this time to time!

When that is all mixed, add in your cream slowly while mixing when it comes to a nice thin mashed potato you can stop. Salt and pepper to taste.

Pile into a large casserole dish. Top with cheddar and Parmesan cheese then spread pieces of your prosciutto over the top.

Bake at 400 for 20-30 minutes.

When its golden on top its done.

Sprinkle the top with scallions or chives just before serving.

Enjoy =)
