🍽 Key Ingredients
You only need these 4 ingredients below to make perfect mashed potatoes with sour cream every time!
Potatoes - Russet potatoes are one of the best potatoes out there for making mashed potatoes because they are starchy and create the perfect fluffy mashed potatoes.
Butter - The butter adds flavor, richness, and creaminess to your mashed potatoes and helps to bind them together.
Sour cream - Full-fat sour cream adds a slight tanginess and extra creaminess to the mashed potatoes.
Cheese - A cup of shredded cheddar cheese will give the creamy mashed potatoes a stringy texture and rich cheesy flavor.
I have found that either Russet or Yukon gold potatoes work best for mashed potatoes.
If you don't have sour cream, you could use heavy cream. Using cream will make the mashed potatoes sweeter but still give you that creamy texture. Or you could use whole milk for a lighter flavor.
Cheddar is the most popular cheese to use in mashed potatoes, but you could substitute it for other types of cheese like Gruyere, cream cheese, mozzarella cheese, or Parmesan cheese.
🔪 How to make
Making mashed potatoes with sour cream is the easiest thing in the world! All you need are 4 simple ingredients and 30 minutes, and you'll have yourself a delicious side dish that everyone will love.
- Wash, peel, and chop the potatoes into quarters or sixths if they are large.
Set a large pot over high heat half full with water and add the chopped potatoes with a tablespoon of salt. Make sure the water is covering the potatoes.
Tip: Once the water comes to a boil, set a timer for 20 minutes, and continue to boil them. After 20 minutes, stab them with a fork to check if they are soft. If they are still a bit hard in the center, cook them for 5 more minutes until fork tender.
Drain potatoes and allow them to cool in the pot for 5 to 10 minutes before mashing them with a potato masher or a fork.
Add sour cream, butter, and cheese while mixing thoroughly to incorporate them into the fluffy potatoes. Add salt to taste and transfer mashed potatoes to a serving bowl.
Serve them with chopped green onions and a knob of butter for the perfect side dish, or use the mashed potatoes with sour cream as a filling for this pierogi recipe.
💭 Cooking tips
If you're using whole milk instead of sour cream or using half and half, it is better to use warm milk instead of cold. Adding cold milk from the fridge will cool the temperature of the mashed potatoes and not give them a creamy texture, unlike warm/hot milk.
Don't over-mix the potatoes
The key to creamy and buttery potatoes is to only mix the ingredients until they are incorporated. Once the cheese has melted and the mashed potatoes have a smooth texture, they are ready for serving.
Don't overcook the potatoes
Another way to spoil the dish is by overcooking the potatoes. They should be soft enough to stab with a fork but not enough to break them into pieces by touching them.
The cooling period
For the fluffiest mashed potatoes, make sure to let them cool slightly in the pot after draining the water. This allows the steam from the potatoes to escape and makes it easier to mash them.
📖 Recipe Variations
There are so many ways you can put your own spin on these mashed potatoes with sour cream! From adding various herbs and spices to adding ham or bacon, the options are endless! Here are a few suggestions to get you started:
Sour cream mashed potatoes with roasted garlic
Roast 4 cloves of garlic in olive oil in a preheated oven at 375°F for about 20 minutes until golden and tender. Squeeze the roasted cloves into the mashed potatoes and mix well. Check out our thorough guide on how to roast garlic.
Sour cream mashed potatoes with bacon
