Ingredients You’ll Need

The ingredient list is straightforward, but each ingredient contributes to the final texture and flavor.

5 Pounds Russet Potatoes

Russet potatoes are the foundation of this recipe. They are peeled and cut into large chunks before being simmered until fork tender.

The recipe specifically calls for 5 pounds of russet potatoes.

1 Bay Leaf

The bay leaf cooks with the potatoes and adds subtle flavor. It is discarded before the potatoes are mashed.

1 1/2 Sticks Unsalted Butter

The butter is used at room temperature and added before the other dairy ingredients.

This is one of the recipe’s most important techniques because the supplied instructions specifically recommend adding the fat first for especially creamy mashed potatoes.

1/2 Cup Sour Cream

Sour cream adds richness and a gentle tang that balances the buttery potatoes.

1/4 Cup Heavy Cream

Heavy cream contributes additional richness and helps create the creamy texture.

1/2 Cup Milk

Milk loosens the mashed potatoes and helps bring them to the desired consistency.

The recipe specifically recommends adding the milk gradually rather than adding it all at once.

Salt and Pepper to Taste

Salt and pepper finish the potatoes and allow you to adjust the seasoning according to taste.

The recipe recommends salting the cooking water as well as seasoning the potatoes after the other ingredients have been incorporated.

Tools and Equipment

You only need a few basic kitchen tools:

• Large pot
• Colander or strainer
• Potato masher
• Measuring cups
• Knife
• Cutting board
• Spoon or spatula
• Crockpot, if keeping the potatoes warm for serving

A large pot is especially helpful because 5 pounds of potatoes require enough room to cook evenly.

How to Make Creamy Mashed Potatoes

Step 1: Prepare the Potatoes

Peel the potatoes and cut them into large chunks.

Add the potatoes to a large pot along with the bay leaf.

Fill the pot with cold water.

Sprinkle the water with salt.

Bring the potatoes to a boil.

Starting the potatoes in cold water helps them cook through as the water heats.

Step 2: Cook Until Fork Tender

Cook the potatoes for 15–20 minutes, or until they are fork tender.

The potatoes should be soft enough that a fork can easily pass through them.

Avoid leaving them cooking longer than necessary because the recipe is designed around potatoes that are tender and ready to mash after the 15–20 minute cooking period.

Step 3: Drain the Potatoes

Drain the potatoes.

Transfer them back to the pot.

Discard the bay leaf.

At this point, the potatoes are ready for the butter.

Step 4: Add the Butter First

Add the softened room-temperature butter.

Mash the potatoes until smooth and lump free.

This step is especially important to the recipe’s method.

The supplied tip explains that adding the fat before the liquids allows the fat to coat the starch, helping produce the best mashed potato texture.

Step 5: Add the Sour Cream and Heavy Cream

Add the sour cream and heavy cream.

Continue mashing until the potatoes are smooth and fluffy.

The combination of sour cream and heavy cream gives the potatoes their characteristic richness and creamy consistency.

Step 6: Add the Milk Gradually

Add the milk and stir.

Then add the remaining milk as needed.

Do not automatically add all of the milk at once.

The potatoes need time to absorb the liquid, and adding all of it at once can result in a gummy or stiff texture according to the recipe’s notes.

Step 7: Season and Serve

Season with salt and pepper to taste.

Taste the potatoes and adjust the seasoning as needed.

Serve immediately.

The Secret to Extra Creamy Mashed Potatoes

The recipe’s most important technique is simple: add the butter before the liquids.

Once the potatoes have been cooked and drained, the softened butter goes directly into the warm potatoes.

The recipe notes that adding the fat first allows it to coat the starch. This helps create the rich, creamy texture that makes these mashed potatoes stand out.

Only after the butter has been incorporated should the sour cream, heavy cream, and milk be added.

Why Room-Temperature Butter Matters

The recipe specifically calls for 1 1/2 sticks of unsalted butter at room temperature.

Softened butter is easier to incorporate into the hot potatoes. It can coat the potato starch thoroughly as you mash, helping produce a smooth texture.

This is also why the recipe places the butter before the liquid ingredients.

Why You Should Add the Milk Gradually

It can be tempting to pour all of the milk into the potatoes at once, but the recipe specifically advises against this.

Potatoes need time to absorb liquid.

Adding the milk gradually gives you more control over the final texture and helps prevent the potatoes from becoming gummy or stiff.

Start with the specified amount and stir before deciding whether additional milk is needed.

How to Avoid Gummy Mashed Potatoes

The recipe highlights another important technique: don’t overmix.

Just like with certain baked goods, overmixing mashed potatoes can lead to a gummy consistency.

Mash the potatoes until smooth and lump free, then incorporate the dairy ingredients without excessively mixing the potatoes.

The goal is smooth and fluffy rather than heavily worked.

Why Salt the Potatoes Twice?

The recipe recommends seasoning the potatoes at two different stages.

First, salt the water before the potatoes boil.

Then, once the butter, sour cream, heavy cream, and milk have been incorporated, season the finished potatoes with salt and pepper to taste.

This gives you an opportunity to season the potatoes throughout the cooking process and then adjust the final flavor at the end.

Flavor Profile

These mashed potatoes have a rich and comforting flavor profile.

Buttery: The 1 1/2 sticks of unsalted butter provide a rich foundation.

Creamy: Sour cream, heavy cream, and milk create the signature creamy consistency.

Slightly tangy: Sour cream adds a subtle tang that keeps the potatoes from tasting overly heavy.

Savory: Salt and pepper bring the entire dish together.

Comforting: Russet potatoes and rich dairy make this a classic comfort-food side.

Tips for the Best Creamy Mashed Potatoes

Cut the Potatoes Into Large Chunks

The recipe calls for large chunks. Keep the pieces reasonably consistent so they cook at a similar rate.

Start With Cold Water

Add the potatoes to the pot and fill with cold water before bringing everything to a boil.

Salt the Cooking Water

The recipe specifically recommends salting the water.

Check for Fork Tenderness

Cook for 15–20 minutes, checking that the potatoes are fork tender before draining.

Add Butter Before Liquids

This is one of the most important techniques in the recipe.

Don’t Add All the Milk Immediately

Give the potatoes time to absorb the liquid and add the remaining milk as needed.

Don’t Overmix

Mash and stir only enough to create the smooth, fluffy texture you want.

Taste Before Serving

Salt and pepper are added to taste, so always taste the finished potatoes before serving.

Make-Ahead Creamy Mashed Potatoes

One of the biggest advantages of this recipe is that it can be made ahead.

The supplied make-ahead instructions state that you can cook the potatoes as directed and refrigerate them for up to 3 days.

When you are ready to eat them, rewarm the mashed potatoes on the stovetop with a bit of butter and a splash of milk.

This makes the recipe particularly useful for holiday cooking when several dishes need to be prepared around the same time.

Keeping Mashed Potatoes Warm

The recipe also provides an option for keeping the potatoes warm on the day you make them.

Prepare the potatoes as directed and place them in a crockpot on the low/warm setting until you are ready to serve.

This can be especially useful when preparing a large meal where the main course and side dishes need to be ready at different times.
