These Boursin Mashed Potatoes are Yukon Gold potatoes mashed with butter, heavy cream, and a 5-ounce package of Boursin cheese, then finished with salt, pepper, and chopped chives. They take about 40 minutes, serve 8, and can be made up to a day ahead, which makes them an easy side for Thanksgiving.
Boursin cheese is soft and creamy, with herbs and garlic that melt straight into warm potatoes. If you’ve ever set out Boursin with crackers, you know it disappears fast, and the same thing happens here. It gives the potatoes extra creaminess, plenty of flavor, and just enough salt so you don’t have to mess with a bunch of extra seasonings. Any flavor will work, but Garlic & Fine Herbs is the one most people grab, and it fits right in on a holiday plate or next to a roast.
The method is simple: boil and mash the potatoes, stir in the butter and Boursin, then finish with cream, salt, and pepper. They’re easy to make, feed a crowd, and reheat well. If you like this one, my Cheddar and Chive Mashed Potatoes and Parmesan Crusted Potatoes are two more potato sides to try.
