Ingredients You’ll Need
Here’s a quick look at the ingredients you need to make this twice baked potato casserole. For a full list of ingredients and amounts please head to the full recipe.
- Russet potatoes – The star of the show; I always recommend russet potatoes because they come out light and fluffy. For a denser, more rich potato texture, you can use yukon gold potatoes.
- Milk, sour cream, melted butter – Mix these three together for the delicious potato filling
- Shredded cheddar cheese – I like using orange cheddar for the look it gives the casserole, but you can use white cheddar, too
- Bacon – I like using pork bacon, but you could also use turkey bacon. Be sure to cook bacon until crispy for that crunch you know from a baked potato topped with bacon bits!
- Fresh chives – these add an extra pop of flavor to this recipe. I season the smashed potatoes with salt and onion powder, but you can also add garlic powder and black pepper for a more intense flavor.

Recipe FAQs
Is it better to bake a potato at 350 or 400?
To get a crispy skin and fluffy interior, I recommend baking at 400 for 50 minutes.
Why is it called a twice baked potato?
A twice-baked potato is named for the cooking process since it is baked twice. First, you bake the potatoes alone. Then, you take the filling out, combine it with other ingredients, place it back in the potato and then bake again. The process is slightly different for this recipe though since it is a casserole!
How long do I put twice-baked potatoes in for?
First, you cook the potatoes by themselves for 50 minutes at 400 degrees. Then you cook the casserole for 20-25 minutes at 350 degrees.
Storage of Twice Baked Potato Casserole
Allow the twice baked potato casserole to cool completely and then transfer any leftovers to an airtight container. Place in the fridge and store in the refrigerator for up to 4 days.
Reheat in the oven or in the microwave until just warmed through. Top with fresh herbs and serve.
This recipe also freezes perfectly. Transfer to a freezer safe container after cooling and freeze for up to 3 months. To keep it in the same pan, wrap it in plastic wrap and foil to make it airtight. Thaw one day before you would like to eat, and heat it in the oven.
