Notes
- To store, place in an airtight container and refrigerate for up to 5 days. I do not recommend freezing as the cheese comes out a little wonky, in my personal opinion.
- If you want to use homemade mashed potatoes instead of instant, you’ll want to wash, peel, and chop 4 pounds of russet potatoes. Place them in a large boiling pot and cover with water. Boil until fork tender. Cut the butter into smaller pieces. Add the butter, salt, and milk to the potatoes and use a hand mixer to mix the ingredients until creamy. Add the sour cream and stir. Then, follow steps 5-9 as usual. Add more milk, as needed, to reach the creamy consistency you prefer.
- Do not overbake, or the cheese will come out hard, and that’s not fun to eat.
- If you prefer other toppings on your usual baked potatoes, add those at the proper time, if desired.
- Do not add the green onions until after it’s baked, or they will turn out gross.
