These Mashed Potatoes with Cheese are an easy-to-make comfort food that tastes special without requiring complicated techniques.
This version of mashed potatoes is rich and satisfying, using Boursin, a soft, spreadable cheese that gets blended into the sauce and then added to the potatoes, creating a smooth, restaurant-style texture without the need for heavy mixing.

What Makes Mashed Potatoes Gummy?

Gummy potatoes create an unpleasant, gluey texture that isn’t very appetizing. The key to avoiding this and making the fluffiest mashed potatoes is to minimize excess mixing and limiting the amount of milk added. This recipe incorporates a spreadable cheese into a sauce before the potatoes are added, allowing it to blend seamlessly into the potatoes without the need for over-stirring to get them creamy.

Ingredients

Ingredients for mashed potatoes with cheese including peeled potatoes, milk, butter, salt, and boursin cheese

  • Boursin: or any other soft spreadable cheese such as cream cheese or cream cheese with garlic and herbs
  • Milk: Whole milk or non-fat, both are fine to achieve a smooth, cohesive mash.

Why Boursin Works So Well in Mashed Potatoes

These creamy, cheesy mashed potatoes feel fluffy yet creamy. Since Boursin is already smooth and spreadable, it melts easily when stirred into the melted butter. Making a Boursin butter sauce before adding the potatoes means less mixing. The texture stays light, while the Boursin cheese provides subtle herb and garlic flavors throughout

Substitutions & Variations

  • You can use cream cheese in place of Boursin. Incorporate it into the butter the same way you would as the Boursin.
  • For an ultra-smooth texture, make whipped mashed potatoes. Simply mash the potatoes, then add them to a blender and blend. Slowly add the Boursin cheese mixture, blending on low speed until just combined. Don’t overmix to avoid gumminess.
  • Make baked mashed potatoes: Transfer the finished mashed potatoes to a buttered baking dish, dot with butter, and bake until heated through. This works well as make-ahead mashed potatoes if you are entertaining.
  • For a lighter, higher-protein variation, try mashed potatoes with cottage cheese. Pre-blend cottage cheese and add it to the melted butter as you would the Boursin. You won’t need to add milk since the cottage cheese already contains a fair amount of liquid.
  • If you are short on time, make these Yukon Gold mashed potatoes with skins on. Their skins are thin and tender, unlike Russet potatoes. You’ll still get all the same great flavor with the benefit of added nutrients.

What Kind of Potatoes Are Best to use?

For consistently great results, Yukon Gold mashed potatoes are the best choice. They mash smoothly without becoming too starchy or dry (so you don’t need to add as much milk).
In short, stick with Yukon Gold; they are the best potatoes for creamy mashed potatoes with a naturally creamy texture.

Expert Tips

  • Melt the butter and cheese together first to create a smooth, unified base before adding the potatoes.
  • Creating a smooth cheese mixture upfront means the potatoes require less mixing later, which helps protect their texture.
  • Soft cheese is ideal for mashed potatoes because it blends instead of melting; in Boursin cheese mashed potatoes, the cheese is completely incorporated into the potatoes
  • Mash gently and stop as soon as the potatoes are incorporated into the cheese mixture to avoid releasing excess starch (which makes them gummy).
  • Looking to make a small batch? While this recipe feeds a crowd, you can adjust it to make mashed potatoes for 2 or 4 people by dividing the ingredients.

Make Ahead and Storage Info

This recipe is great for make-ahead mashed potatoes and holds its texture well when reheated gently.
Refrigerator: Store the mashed potatoes in an airtight container for up to 5 days. Reheat slowly on the stovetop or in the microwave. If they look dry, add a splash of milk.
Freezer: Mashed potatoes can be frozen for up to 2 months. Thaw overnight in the refrigerator, then reheat gently, adding milk or butter to restore creaminess.

Ingredients
  

  • 3 pounds Yukon gold potatoes peeled and cut in half
  • 1 tablespoon salt plus more to taste
  • ¼ cup (57g) unsalted butter
  • 1 package (150g) Boursin or other spreadable cheese
  • 6 tablespoons (85ml) milk non-fat or whole milk

Instructions
 

  • Place prepared potatoes in a large heavy-bottomed pot, add the salt, and fill with cold water (enough to cover the potatoes by 1-2 inches).
  • Bring to a boil, then reduce the heat to medium-high.
  • Cook the potatoes until fork-tender (about 15 minutes).
  • Drain the potatoes into a colander and set aside.
  • Place the empty pot over medium heat and add the butter. Once it begins to melt, cut the cheese into quarters, add it to the pot, and stir until smooth and fully combined.
  • Turn the heat to low, transfer the potatoes back to the pot, and mash them into the cheese mixture using a potato masher.
  • Add the milk and stir until just combined.

Notes

Boursin in mashed potatoes works especially well because soft cheese blends smoothly into a sauce, which then gets mixed into the potatoes. Boursin is a better option that traditional shredded cheese, which can contribute to clumping and a rubbery texture when reheated.
If you’re making mashed potatoes for 2, you can scale down this recipe without changing the texture.
If you’re troubleshooting texture and asking ‘why are my mashed potatoes gummy’, it is usually a result of adding too much liquid and overmixing.
