Why This Mashed Potato Sundae Recipe Will Become Your Go-To
The Secret Behind Perfect Mashed Potato Sundae
The secret to an unforgettable Mashed Potato Sundae lies in the simplicity of the dish itself. By starting with a base of perfectly creamy, buttery mashed potatoes, you create a blank canvas for a flavor explosion. The key is to use the right potatoes – Russets are the ideal choice, as their starchy texture and fluffy consistency make them perfect for mashing. Once you’ve got that down, it’s all about the toppings. The combination of salty, crispy bacon, melted cheddar cheese, cool sour cream, and fragrant chives takes this dish to the next level, elevating the humble mashed potato into something truly extraordinary.
Essential Ingredients You’ll Need
- 3 pounds russet potatoes, peeled and cut into 1-inch chunks: Russet potatoes are the gold standard for mashed potatoes, with their light, fluffy texture that’s perfect for this dish.
- 1/2 cup unsalted butter: Butter is the key to creamy, flavorful mashed potatoes, and the unsalted variety allows you to control the seasoning.
- 1 cup whole milk: Whole milk adds richness and creaminess to the mashed potatoes, creating a luxurious texture.
- 1 teaspoon salt: A pinch of salt enhances the natural flavors of the potatoes and balances the richness of the dish.
- 1/2 teaspoon black pepper: A little bit of black pepper adds a subtle kick and depth of flavor.
- 8 slices bacon, cooked and crumbled: Crispy, salty bacon is the perfect contrast to the creamy mashed potatoes, adding a delightful crunch.
- 1 cup shredded cheddar cheese: Melted cheddar cheese takes this dish to the next level, adding a savory, comforting element.
- 1/2 cup sour cream: Cool, tangy sour cream balances the richness of the dish and provides a refreshing contrast.
- 2 tablespoons chopped chives: Fresh chives add a pop of color and a delicate onion-y flavor that ties the whole dish together.
Step-by-Step Mashed Potato Sundae Instructions
Preparing Your Mashed Potato Sundae
With a prep time of just 15 minutes and a cook time of 25 minutes, this Mashed Potato Sundae recipe is a quick and easy way to create a show-stopping dish in under 40 minutes. All you’ll need is a large pot, a masher or ricer, and a few simple ingredients.
1- Start by peeling and cutting the russet potatoes into 1-inch chunks, making sure they’re all a similar size for even cooking.
2- Place the potato chunks in a large pot and cover with cold water. Bring the water to a boil over high heat, then reduce the heat to medium-low and let the potatoes simmer for 15-20 minutes, until they’re fork-tender.
3- Drain the potatoes in a colander, then return them to the pot. Add the butter, milk, salt, and pepper, and use a masher or ricer to mash the potatoes until they’re smooth and creamy.
4- Stir in the crumbled bacon, shredded cheddar cheese, sour cream, and chopped chives, making sure everything is evenly distributed.
5- Taste the mashed potato mixture and adjust the seasoning as needed, adding more salt or pepper to suit your preferences.
6- Serve the Mashed Potato Sundae warm, spooning the creamy, flavorful mixture into bowls and letting your guests top it with any extra toppings they desire.
Pro Tips for Success
- Don’t over-mash the potatoes – you want a creamy, fluffy texture, not a gluey, overworked consistency.
- For extra richness, use a combination of butter and heavy cream instead of just milk.
- Fry the bacon until it’s extra crispy for the perfect contrast in texture.
- Shred the cheese yourself for better melting and flavor than pre-shredded cheese.
- Chop the chives just before adding them to the mashed potatoes to preserve their vibrant color and fresh taste.

Frequently Asked Questions
Q: Can I use a different type of potato instead of russets?
A: While you can technically use other potato varieties, such as Yukon Gold or red potatoes, russets are the best choice for this Mashed Potato Sundae recipe. Their starchier, fluffier texture is essential for achieving the perfect creamy mashed potato base.
Q: How can I adjust the recipe to make it for a larger or smaller group?
A: This Mashed Potato Sundae recipe is designed to serve 6 people. To scale it up or down, simply adjust the ingredient quantities proportionally. For example, to serve 12 people, double all the ingredients, or to serve 3 people, reduce the quantities by half.
Q: Can I make Mashed Potato Sundae ahead of time?
A: Absolutely! Mashed Potato Sundae is a great make-ahead dish. You can prepare the mashed potato mixture up to 4 days in advance and store it in the refrigerator. When ready to serve, simply reheat the potatoes on the stovetop or in the microwave, adding a splash of milk or cream to restore the creamy texture.
Q: How can I prevent the mashed potatoes from becoming gummy or dense?
A: The key to preventing gummy or dense mashed potatoes is to avoid over-mashing them. Be sure to use a masher or ricer, rather than a food processor or blender, which can overwork the potatoes and make them gummy. Additionally, be mindful not to add too much milk or butter, as this can also lead to a dense, heavy texture.
Q: Can I freeze Mashed Potato Sundae?
A: Yes, Mashed Potato Sundae freezes extremely well. Once the mashed potato mixture is prepared, simply transfer it to a freezer-safe container and freeze for up to 3 months. When ready to serve, thaw the potatoes in the refrigerator overnight and then reheat them on the stovetop or in the oven until heated through.
