Why are russet potatoes the best for mashing?
Russet potatoes have a very high starch content making a fluffier and more flavorful mashed potato.
Another good high starch potato choice for this mashed potato casserole is the Yukon gold potato if you happen to prefer those over russet potatoes.
Why should I start my mashed potatoes in cold water?
Always start cooking the peeled and cubed potatoes in cold water.
It may seem counter-intuitive, but starting the potatoes in hot water will risk the chance of them being cooked unevenly, leaving some thoroughly cooked and some not.
You always want all your potatoes to be perfectly cooked at the same time.
When making mashed potatoes, always remember to:
- Start them in cold water
- Generously salt the cooking water
- Drain the potatoes thoroughly after cooking
- Add the drained potatoes back into the hot pot
- Warm the milk before adding it to the potatoes for better absorption.
- Always add room temperature butter, cream cheese, and shredded cheese for better blending
- Use a potato ricer for creamier potatoes

What is the best way to reheat this mashed potato casserole after it's been refrigerated?
The most important thing is to allow the potato casserole to sit at room temperature for 60 minutes before baking.
Then bake the covered casserole in a preheated 350-degree oven for 45 minutes, remove the cover and cook for an additional 15-20 minutes until the potatoes are hot and steamy all the way through.
How much ahead can I make this holiday side dish?
You can make this up to 3 days before serving.
To store, allow the casserole to cool completely, cover tightly with foil or plastic wrap, and refrigerate.
Can this make-ahead side dish be frozen?
Yes!
Allow the potatoes to cool completely before freezing. Cover the casserole dish well with foil or plastic wrap and freeze for up to 2 months.
Thaw completely before heating in a 350-degree oven for 50 minutes, covered, and 15 minutes uncovered.
Stir the potatoes thoroughly before serving when you're reheating after freezing.
The easy instructions for preparing this recipe for Make-Ahead Cheesy Horseradish Mashed Potato Casserole are as follows:
- Peel and dice the potatoes into approximate 1½" cubes.
- Place the potatoes in a large stockpot and add enough cold water to cover.
- Allow the butter and cheeses to come to room temperature.
- Salt the potato cooking water liberally, and cover the pot.
- Bring the potatoes to a low boil (keeping an eye on them so they don't boil over). Approximately 20 minutes.
*NOTE – Keeping a wooden spoon in the pot while the potatoes cook will keep the cooking water from boiling over.
- Once the potatoes are fork-tender, carefully drain the potatoes and immediately add them back into the hot pot.
- Add the room-temperature butter, cream cheese, salt, and pepper, and warm milk to the cooked potatoes.
- OR, if using a ricer, rice the potatoes before adding the remaining ingredients.
- After the butter, milk, cream cheese, and seasonings are mashed in, add in the prepared horseradish, shredded cheddar cheese, and grated nutmeg.
- Spoon the mashed potatoes evenly into a prepared casserole dish which has been sprayed with cooking spray.
- Cool the potatoes completely (if making in advance), and cover well with aluminum foil or plastic wrap.
- Keep refrigerated for up to 2 days, or freeze for up to 2 months.
- If serving the same day, add the mashed potato casserole immediately into a preheated 350-degree oven and heat for 20 minutes.
