Key Ingredients
- Potatoes – we like to use red potatoes for this recipe, but you can also use Idaho potatoes or Yukon Gold potatoes. In this recipe, we boil the potatoes before mashing and mixing, but you can also bake the potatoes in foil on a baking sheet for about 45 minutes-1 hour at 400 degrees.
- Cream Cheese – you want this to be room temperature so that it is easier to mix together with the other filling ingredients.
- Sour Cream – either lite or full fat will work.
- Milk – we recommend using whole milk, or even heavy cream, for this casserole.
- Butter – either salted or unsalted will work.
- Onion Powder and Garlic Powder – these spices add great flavor that are slightly sweeter and more mild than the fresh versions.
- Bacon – any kind of bacon will work. You want to dice, cook and then drain your bacon before adding to the casserole.
- Cheddar Cheese – you can purchase shredded cheese or shred your own.
- Chives – we like fresh chives but you can also use green onions.
How to Make Twice Baked Mashed Potatoes Casserole
- Preheat oven to 350 degrees.
- Wash the potatoes, peel (optional), and cut into 1″ cubes. Place the potatoes in a large pot, add 1 Tablespoon of salt and cover with water.
- Bring to a boil, and boil potatoes for 15-20 minutes or until they are fork-tender.
- Once cooked, drain the water, then add the potatoes back to the pot. Mash the warm potatoes with a potato masher (or potato ricer) and add in your cream cheese, sour cream, milk, butter, salt, pepper, onion powder and garlic powder.
- Mix well, then spread the mashed potato mixture into a 9″x13″ baking dish and sprinkle bacon bits and shredded cheese evenly over the top.
- Bake in a preheated oven for 25-30 minutes, or until the cheese is melted and golden brown, and the potatoes are warm throughout. Remove from the oven and sprinkle with the remaining bacon bits, shredded cheese and fresh chives. Enjoy!
