Step-by-Step Instructions for Making Twice Baked Potato Casserole

Follow these easy steps to make your very own Twice Baked Potato Casserole:

1. Preheat the Oven:

Start by preheating your oven to 400°F.

2. Prepare the Potatoes:

Scrub the russet potatoes clean, making sure to remove any dirt. Pat them dry with a towel, then rub them with a thin layer of canola oil. Place them on a baking sheet and bake for 40 minutes, or until the potatoes can be easily sliced through. Once done, remove them from the oven and set them aside to cool slightly.

3. Cook the Bacon:

While the potatoes are baking, cook the bacon in a large pan over low heat. As the bacon starts to curl up, use tongs to flip it periodically until it’s evenly cooked. Once done, transfer the bacon to a paper towel-lined plate to cool. Crumble the bacon once it has cooled slightly. Set some of the crumbled bacon aside for topping the casserole later.

4. Prepare the Potatoes for Mashing:

Once the potatoes are cool enough to handle, leave the skins on two of the potatoes and peel the skins from the remaining potatoes. Cut each potato into thirds and transfer them to a large mixing bowl.

5. Mash the Potatoes:

Add the crumbled bacon (except for the reserved topping), butter, sour cream, and cheddar cheese to the potatoes. Sprinkle in the seasoned salt, salt, and pepper to taste. Use a potato masher to give the mixture a rough mash.

6. Add the Milk:

Gradually add whole milk, mashing in between each addition to reach your desired consistency. You may not need to use the entire cup of milk, but typically, I add all of it for a smoother texture.

7. Assemble and Bake:

Transfer the mashed potato mixture to a lightly greased 9 x 13-inch baking dish. Top with the reserved crumbled bacon and an additional sprinkle of shredded cheddar cheese.

8. Bake the Casserole:

Bake the casserole, uncovered, in the oven for 20-25 minutes, or until the top is golden and bubbly.

9. Garnish and Serve:

Once the casserole is baked, remove it from the oven and garnish with freshly sliced green onions. Serve immediately, and enjoy!
