Potato Base

Method

Preparation of Potato Base

  1. 1

    Cook the Potatoes

    Preheat your oven to 400°F (200°C). Wash the russet potatoes thoroughly, then prick each potato with a fork to allow steam to escape. Bake them in the oven for about 45-60 minutes, or until they are tender when pierced with a fork.

  2. 2

    Mash the Potatoes

    Once the potatoes are cooked, remove them from the oven and allow them to cool slightly. Cut each potato in half and scoop out the flesh into a large mixing bowl, discarding the skins.

  3. 3

    Mix Ingredients

    To the bowl with the potato flesh, add the unsalted butter, sour cream, milk, salt, black pepper, garlic powder, shredded cheddar cheese, and chopped green onions. Mash the mixture until smooth and creamy, ensuring all ingredients are well combined.

Assembly and Baking

  1. 4

    Prepare Baking Dish

    Preheat your oven to 350°F (175°C). Grease a large casserole dish with cooking spray or butter.

  2. 5

    Layer the Potato Mixture

    Spread the potato mixture evenly in the prepared casserole dish, smoothing the top with a spatula.

  3. 6

    Add Toppings

    Sprinkle the bacon bits, followed by the remaining shredded cheddar cheese over the top of the potato mixture. Finally, sprinkle chopped green onions on top.

  4. 7

    Bake the Casserole

    Place the casserole in the oven and bake for 25-30 minutes, or until the top is golden and bubbly.

  5. 8

    Serve

    Remove the casserole from the oven and allow it to cool for a few minutes. Serve warm as a delicious side dish.
