Prepare your pizza dough and let rise. Once ready, press it into a pizza pan.

Preheat oven to 375. While oven is heating, boil potatoes – I usually boil mine for about 30 minutes, depending on the size, or until fork tender.  In a saucepan over medium head, add 1 tablespoon butter and sliced onions. Let caramelized, then set aside. Drain potatoes and set back in pot. Once oven is heated, add pizza dough and bake for 10-15 minutes.

Add 1/4 cup butter and milk to potatoes and mash. Season well with salt and pepper. If you have a wonderful mashed potato recipe, now is the time to use it. Make sure potatoes are creamy and smooth. Fold in 1/2 cup shredded cheese.

Remove pizza crust from over and begin spreading with potato mixture. I used a frosting spatula to spread evenly. Sprinkle with caramelized onions and remaining cheese. Bake for 25-30 minutes.
