Mashed potatoes are a classic side dish that can be found accompanying a wide variety of meals. The texture and flavor of mashed potatoes can vary greatly depending on the ingredients and preparation methods used. The liquid used to cook and mash the potatoes is one of the key factors that impacts the final result. The two most common options are milk and water. But which one results in better mashed potatoes?
Water vs Milk for Mashing Potatoes: The Main Differences
Water and milk each have their own distinct properties that affect mashed potatoes differently:
Fat Content
– Water has no fat, while whole milk contains about 3.25% milk fat.
– The fat in milk gives mashed potatoes a richer, creamier texture.
– Using water results in a lighter, fluffier texture.
Acidity
– Water has a neutral pH of around 7.
– Milk is slightly acidic, with a pH between 6.5-6.7.
– The acidity in milk react with the starch in potatoes, helping to soften the cell walls. This results in a smoother mash.
Flavor
– Water adds no distinct flavor.
– Milk has a sweet, creamy taste that complements the potatoes.
– Butter is often added along with milk, enhancing the flavor further.
Nutritional Value
– Water adds no nutritional value.
– Milk provides protein, calcium, vitamin D, vitamin A, vitamin B12, riboflavin, and phosphorus.
– The nutrients in milk make it more nutritious choice.
Cost
– Water is free.
– Milk adds to the cost of the dish.
Does Milk or Water Make Better Mashed Potatoes?
With the differences laid out, which liquid makes the better mashed potatoes comes down to personal preference. Here are some factors to consider when deciding:
Texture
For light and fluffy mashed potatoes, water is the better choice. The potatoes mash up easily with water, absorbing the liquid well. Overworking the potatoes can lead to gluey mashed potatoes.
Milk produces a rich, creamy mashed texture. The milkfat coats the potato cells, resulting in a smooth, velvety mash. Milk is the traditional choice for holidays and other special occasion cooking.
Flavor
The sweetness and extra fat from milk enhance the flavor of the potatoes. Milk offers a more indulgent, comforting character.
Water makes the potato flavor shine through without altering it. This allows the potatoes to feature more prominently compared to using milk.
Dietary Needs
For vegan, dairy-free, or low-fat diets, water is the best option. Milk contains dairy and added saturated fat. Replacing milk with non-dairy alternatives like almond or oat milk also works.
If you want to maximize nutrients or follow dietary guidelines for getting enough calcium and vitamin D, using milk is an advantage. The nutrients in milk make it a better choice if you have specific nutritional needs.
Budget
When cost is a main concern, sticking to simple water keeps mashed potatoes budget friendly. While milk adds flavor, you can still get decent results without the added expense.
Time Investment
Milk takes slightly longer to absorb into the potatoes, so the mashing process can take a few more minutes. Using water is faster since it incorporates rapidly.
Tips for Making Perfect Mashed Potatoes
Regardless of whether you use milk or water, there are some tips to follow for making the best mashed potatoes:
Choose the Right Potato
Starchy, high-moisture potatoes like Russets work best. They break down easily and absorb liquid well. Waxy potatoes hold their shape even when mashed.
Cook Properly
Potatoes should be cooked until fork-tender but not falling apart. Leaving them slightly underdone helps retain texture after mashing.
Drain and Dry
Drain the potatoes well after boiling and let them steam dry for 1-2 minutes. This removes excess moisture, so they’ll mash up fluffier.
Mash Thoroughly
Use a masher or ricer for smooth, lump-free spuds. A stand mixer fitted with the paddle attachment also works well.
Don’t Overbeat
Too much mixing makes the starches gluey. Stop when no lumps remain.
Flavor Boosters
Incorporate butter, warm milk, sour cream, cheese, garlic, herbs to amp up flavor.
Keep it Hot
Return mashed potatoes to low heat to keep warm until ready to serve. This prevents clumping or drying out.
Water vs. Milk Mashed Potatoes: Recipe Comparison
To showcase the differences between using water and milk, here are two classic mashed potato recipes for you to try:
Light and Fluffy Mashed Potatoes
Ingredients:
– 3 lbs russet potatoes, peeled and cut into 1″ chunks
– 1⁄2 cup warmed water, plus more as needed
– 4 Tbsp butter
– 1 tsp salt
– 1⁄4 tsp black pepper
Instructions:
1. Place potatoes in a pot and cover with cold water by 1 inch. Bring to a boil over high heat.
2. Lower heat and simmer uncovered for 10-15 minutes until fork tender.
3. Drain potatoes in a colander and place back into dry pot. Let potatoes steam dry for 1 minute.
4. Add butter, salt, and pepper. Mash potatoes while gradually incorporating the warmed water until smooth and creamy. Add more water if needed to reach desired consistency.
5. Serve warm.
Rich and Creamy Milk Mashed Potatoes
Ingredients:
– 3 lbs russet potatoes, peeled and cut into 1″ chunks
– 1 cup whole milk, warmed
– 4 Tbsp butter
– 1 tsp salt
– 1⁄4 tsp black pepper
Instructions:
1. Place potatoes in a pot and cover with cold water by 1 inch. Bring to a boil over high heat.
2. Lower heat and simmer uncovered for 10-15 minutes until fork tender.
3. Drain potatoes and return to pot. Place over low heat for 1-2 minutes to dry out. Remove from heat.
4. Add butter, salt, and pepper. Slowly mash in the warm milk until potatoes are smooth and creamy.
5. For extra richness, whip in more butter, cream cheese, or sour cream (optional).

Frequently Asked Questions
Does milk make mashed potatoes creamier?
Yes, milk results in creamier mashed potatoes than using water. The natural fats and proteins in milk create a richer, smoother mashed texture.
Do you really need milk for mashed potatoes?
No, milk is not required for mashed potatoes. Many recipes use water with equally tasty results. Milk adds richness and valuable nutrients, but water can be used in any recipe calling for milk.
Is too much milk bad for mashed potatoes?
Using too much milk can make mashed potatoes too thin and soupy. For light and fluffy potatoes, a moderate amount of milk is best. Too much moisture leads to a wet, gummy mash.
Can you use heavy cream instead of milk?
Yes, heavy cream can replace milk in mashed potatoes. Because it has a higher fat content, heavy cream makes the potatoes extra rich. Just use less heavy cream than you would regular milk to avoid over-thinning the mash.
Should you put butter in mashed potatoes?
Butter is a great addition to mashed potatoes, whether using milk or water. Aside from adding flavor, butter further enhances the creaminess of the potatoes. A few tablespoons per batch is usually plenty.
The Bottom Line
While personal taste dictates whether water or milk makes the best mashed potatoes, milk is the traditional choice for most recipes. The milkfat contributes rich creaminess and flavor that complement the potatoes beautifully. However, water can be used interchangeably with excellent results too. Just adjust the other seasonings to make up for the lack of milk’s natural sweetness. With a few simple tricks, you can create smooth, fluffy mashed potatoes using either liquid.
