How to Make Cheesy Fondue Mashed Potatoes Recipe
Step 1: Boil the Potatoes
Start by placing your peeled and quartered Russet potatoes in a large pot of cold water. Bringing the water to a boil and gently cooking the potatoes until they are fork tender, usually around 15 to 20 minutes, ensures they cook evenly and become soft enough to mash smoothly.
Step 2: Drain and Prepare for Blending
Once tender, drain the potatoes thoroughly but keep the pot—you’ll need it shortly to bring your creation all together. The still warm pot will help melt the cheese perfectly without breaking down the potatoes further.
Step 3: Blend the Creamy Base
Add the drained potatoes to a food processor along with the heavy cream, butter, minced garlic, dry white wine, kosher salt, black pepper, and a pinch of nutmeg. Blend carefully until the mixture is mostly smooth, creating a rich, flavorful base that captures the essence of a classic fondue.
Step 4: Incorporate the Cheese
Transfer your creamy potato mixture back into the pot over low heat. Stir in the shredded Swiss cheese slowly, allowing it to melt gently. This step is where your mashed potatoes transform into that irresistible cheesy fondue texture that’s gooey, silky, and totally addictive.
Step 5: Final Seasoning Check
Give everything a taste and adjust the seasoning with a little more salt and freshly cracked black pepper if needed. This final tweak ensures every bite bursts with balanced, comforting flavor.

Make Ahead and Storage
Storing Leftovers
If you have any leftovers, let the mashed potatoes cool to room temperature, then transfer to an airtight container. They’ll keep in the fridge for up to 3 days, ready to be enjoyed as a next-day comfort meal.
Freezing
While freshly made is always best, you can freeze portions of this Cheesy Fondue Mashed Potatoes Recipe for up to 2 months. Use freezer-safe containers or heavy-duty freezer bags, making sure to squeeze out as much air as possible to avoid freezer burn.
Reheating
To reheat, thaw in the fridge overnight if frozen, then warm gently on the stovetop or in the oven at low heat. Stir frequently to keep the cheese melted and creamy. Adding a splash of cream or milk while reheating can help refresh the texture.
FAQs
Can I substitute the Swiss cheese with another type?
Absolutely! Gruyere is an excellent alternative, providing a similar melt and nutty flavor. Cheddar can also work, but it will change the flavor profile slightly, introducing a sharper taste.
Is it possible to make this recipe dairy-free?
To make a dairy-free version, try substituting the heavy cream and butter with coconut cream or a non-dairy butter alternative. Choose a dairy-free cheese substitute that melts well, though the classic fondue flavor might be altered.
Can I prepare this recipe ahead of time for a party?
Yes, you can prepare the mashed potatoes a day in advance, then gently reheat them before serving. Just be sure to stir in a little cream to restore creaminess as they rewarm.
How can I make these mashed potatoes extra creamy?
Using a food processor, as suggested in the recipe, helps create that ultra-smooth texture. Also, incorporating the hot cream and butter gradually ensures your potatoes stay luscious without becoming gluey.
What’s the best type of potato for this recipe?
Russet potatoes are ideal for this Cheesy Fondue Mashed Potatoes Recipe because of their high starch content, which yields fluffy and smooth mashed potatoes. Yukon Golds are slightly waxier and can be used as well but result in a denser texture.
Final Thoughts
This Cheesy Fondue Mashed Potatoes Recipe is a total game changer for anyone who loves comfort food with a gourmet twist. It’s easy enough to make on weeknights but impressive enough for special occasions. Once you try it, these cheesy, smooth potatoes will become your go-to side dish for all the meals that deserve a little extra love.
