Mashed potatoes are a side dish that I rarely eat throughout the year, but deem absolutely necessary for holiday celebrations.

There’s nothing quite like the simplicity of fluffy mashed potatoes, but the fact that they’re so simple can also make them boring if they’re not done correctly.

Boursin Mashed Potatoes are a foolproof way to make sure that your mashed potatoes are loaded with flavor, with a fantastic creamy and fluffy texture!

This recipe is naturally gluten-free and can be made dairy free and vegan. (See the Variations & Substitutions section below.)

Ingredients

Believe it or not, Three ingredients is all it takes to make these delicious mashed potatoes! (Not including sea salt.) Here’s what you’ll need:

  • Sea salt. Seasoning the water when you boil potatoes will help flavor the potatoes gently.
  • Russet potatoes. Russets are a high starch potato that whip up light and fluffy, making them ideal for mashed potatoes.
  • Garlic & Herb Boursin Cheese. Boursin is a brand of Gournay cheese, a soft cheese similar in texture to cream cheese. It comes in several flavor varieties, but I really like the garlic and herb for mashed potatoes.
  • Milk. Milk helps to make the potatoes smooth and creamy. I used whole milk, but you can use whatever kind you prefer. If you prefer to make mashed potatoes without milk, you can omit the milk completely. The potatoes will be a bit thicker.

Directions

Boursin Mashed Potatoes are such a great hack for creamy, flavorful mashed potatoes, because Boursin cheese is already packed with herbs, garlic and cream! That means that you don’t have to pick up multiple items at the store in order to get mouthwatering mash.

These mashed potatoes also come together in no time at all, making them ideal for last minute holiday gatherings or family dinners.

Here’s how I make them:

Bring a large pot of water to a boil. It’s always better to go with a larger pot so that the potatoes have room to move around and the boiling doesn’t result in a lot of splattering. Add liberal amount of sea salt to the water; this will infuse the potatoes with flavor as they cook as opposed to having to add salt at the end.

Add the cubed Russet potatoes and cook them until they are fork tender, about 10-12 minutes.

Drain potatoes using a strainer, and add them back to the pot. I like to place the pot back on the hot burner to evaporate any extra liquid.

Add the Boursin cheese and the milk (if using — as I mentioned above, these mashed potatoes can be made without milk if preferred). I feel that the Boursin adds enough salt and flavor to the potatoes, but taste the mixture and feel free to add salt and pepper to taste.

Adding warm milk to potatoes in the pot while mixing with a red hand mixer.

Using a hand mixer or a potato masher, mash until the mixture is smooth and the cheese and milk are fully incorporated. This only takes a minute or two; be careful not to overmix or over-mash as it can cause the potatoes to have a gluey, pasty texture.

Once the potatoes are smooth, they’re all done! Serve them up nice and warm, with a sprinkle of fresh herbs for garnish if desired.
