Boursin Mashed Potatoes Ingredient Highlights
You can use Russet or Yukon gold potatoes. Both are great for mashing! I stick to Russet because that’s how my mom makes them, and they just taste like home to me.
Any percentage of dairy milk or unsweetened, unflavored non-dairy milk will do.
Using unsalted butter gives you more control over the salt content of your potatoes. That being said, if you only have salted butter at home, that works, too. Just make sure you adjust the amount of garlic salt you add so your creamy mashed potatoes aren’t overly salty.
Speaking of garlic salt, I love this ingredient because it adds the extra flavor of garlic and salt simultaneously. Of course, if you aren’t a fan of garlic, just use salt. If you don’t have garlic salt at home, you can also use a combination of salt and garlic powder.
Any flavor of Boursin will do! I used the garlic and fine herbs flavor in the dish pictured, but I’ve also made this with the basil & chive and shallot & chive flavors with great success.
Boursin is just a brand of Gournay cheese! Gournay is a soft, creamy cheese, and Boursin infuses flavors into it like Garlic and Herb, Shallot and Chive, Cracked Black Pepper, Basil and Chive, and more!
You can use a different brand of herbed Gournay cheese and get similar results.
Boursin Mashed Potatoes Tips and Tricks
How to Make Boursin Cheese Mashed Potatoes
To get super creamy mashed potatoes, peel the potatoes completely using a vegetable peeler, leaving behind no skin or bruises.
If you like some potato peel chunks in your mashed potatoes, just leave a couple of strips of peel on during this process. The rest of the steps for this recipe will be the same.
Investing in a potato masher has been a game-changer for my mashed potatoes! It helps to get out all the lumps and crush the potatoes down into little, whip-able pieces.
Start with just ¼ cup milk. Use a hand mixer on high to mix and assess the consistency. Depending on the size of your potatoes and how soft they got while boiling, you may or may not need a little more.
If you feel your potatoes are too thick, add more milk, about 1 tablespoon at a time, whipping in between until you reach your desired consistency. You shouldn’t need more than a maximum of ½ cup.
