Step‑by‑Step Instructions for Creamy Boursin Mashed Potatoes
Step 1: Prep Potatoes
Begin by peeling and cutting 2 pounds of Yukon Gold potatoes into even, 1-inch chunks. This ensures they cook evenly. If you’re not cooking immediately, soak the potato chunks in cold water to prevent browning and keep them fresh until you’re ready.
Step 2: Boil
Place the prepared Yukon Gold potatoes in a large pot and cover them with cold water. Add a generous pinch of salt, then bring the water to a boil over medium-high heat. Boil for about 15–20 minutes, or until the potatoes are fork-tender and easily break apart when pierced.
Step 3: Drain & Steam
Once the potatoes are cooked, carefully drain them in a colander and return them to the hot pot. Cover the pot with a lid and let the potatoes steam for about 5 minutes. This extra step helps to evaporate excess moisture, ensuring your Creamy Boursin Mashed Potatoes are fluffy and not watery.
Step 4: Mash & Mix
Using a potato ricer or a standard masher, begin mashing the steamed potatoes until they reach your desired smoothness. Gradually incorporate 4 tablespoons of butter, about 1/2 cup of warm milk, 1/2 cup of sour cream, and 4 ounces of Boursin cheese. Combine until creamy and well-blended for that luxurious texture.
Step 5: Season
Taste your Creamy Boursin Mashed Potatoes, then season with salt and pepper as needed. This step is essential to enhance the flavors of the rich ingredients, so don’t skip it. Aim for a perfectly balanced, creamy dish that sings with flavor.
Step 6: Serve
Transfer your delicious Boursin Mashed Potatoes to a warm serving bowl, optionally garnishing with fresh herbs for a touch of elegance. Serve them hot alongside your favorite main dishes, and watch as they become the star of your holiday meal!

Boursin Mashed Potatoes Recipe FAQs
What type of potatoes should I use for Boursin Mashed Potatoes?
Absolutely! I recommend using Yukon Gold potatoes for the best creamy texture and flavor. If you can’t find them, Russet potatoes are a suitable alternative, but they may result in a slightly grainier mash.
How do I store leftovers of Boursin Mashed Potatoes?
Store leftovers in an airtight container in the fridge for up to 4 days. I find that the flavors actually improve after a day, making them even more delicious. Just make sure to mix them gently before serving!
Can I freeze Boursin Mashed Potatoes?
Yes, you can freeze them! Portion your Boursin Mashed Potatoes into freezer-safe containers and store them in the freezer for up to 2 months. When you’re ready to enjoy them, thaw them in the fridge overnight and reheat using a splash of milk to achieve that creamy texture again.
What should I do if my mashed potatoes are too gummy?
Very good question! If your potatoes turn out gummy, it’s likely due to over-mixing. Next time, mash just until combined and fluff them with a fork to keep the texture light. If they do get gummy, you can add a little warm milk or cream and stir gently, then allow them to sit for a few minutes to fluff up.
Are Boursin Mashed Potatoes suitable for dietary restrictions?
Definitely! This recipe can easily be adapted for dairy-free diets. Simply substitute traditional milk and butter with almond milk and plant-based butter. Make sure to choose a dairy-free Boursin-style cheese to maintain that herbaceous flavor. Always check for specific allergens based on your needs!
How do I reheat Boursin Mashed Potatoes without losing their creaminess?
For the best reheating results, transfer your leftover mashed potatoes to a saucepan over low heat. Gradually add a splash of milk while stirring until they reach the desired consistency. This method will help restore that lovely creaminess you enjoyed when they were freshly made!
