Ingredients for Boursin Bliss
Here’s what you’ll need to create these dreamy Boursin mashed potatoes. Quality ingredients are key to achieving the best flavor and texture.
- Potatoes: 2 pounds Yukon Gold or Russet potatoes. Yukon Golds will give you a naturally buttery and creamy texture, while Russets result in a lighter, fluffier mash. I personally prefer Yukon Golds for their rich flavor.
- Boursin Cheese: 5.2 ounces Boursin Garlic & Fine Herbs cheese. The star of the show! This creamy, spreadable cheese adds a burst of flavor and melts beautifully into the potatoes. Other Boursin flavors can be used, but Garlic & Fine Herbs is the classic choice.
- Butter: 4 tablespoons unsalted butter. Butter adds richness and helps to create a smooth, velvety texture. Unsalted allows you to control the overall saltiness of the dish.
- Milk or Cream: ½ cup milk or heavy cream. Milk will result in a lighter mash, while heavy cream creates a more decadent and luxurious texture. Feel free to use a combination of both.
- Salt and Pepper: To taste. Seasoning is crucial! Don’t be afraid to add enough salt and pepper to bring out the flavors of the potatoes and Boursin.
- Optional Garnishes: Fresh chives, parsley, or a sprinkle of paprika. These add a pop of color and freshness to the finished dish.
Ingredient Science: Potatoes are primarily composed of starch. When cooked, the starch granules absorb water and swell, contributing to the potato’s soft texture. Overcooking can cause the starch to break down, resulting in gummy potatoes. Adding fat, like butter and Boursin cheese, coats the starch granules, preventing them from sticking together and creating a smoother, creamier texture. The lactose in milk or cream also contributes to the creamy mouthfeel.
Substitution Tips:
- Boursin Cheese: If you can’t find Boursin, you can substitute with another creamy garlic and herb cheese spread. Cream cheese mixed with garlic powder, dried herbs, and a pinch of salt can also work in a pinch.
- Milk/Cream: Use half-and-half or even sour cream for a slightly tangy twist.
- Potatoes: Red potatoes can be used, but they have a waxier texture and won’t be as fluffy.
- Butter: Olive oil can be used as a healthier alternative, but it will alter the flavor.
Expert Tips for Potato Perfection
Here are some of my top tips for making the best Boursin mashed potatoes, based on years of testing and tweaking:
- Start with Cold Water: Place the potatoes in a pot and cover them with cold water. This helps them cook evenly and prevents the outsides from overcooking before the insides are done.
- Salt the Water: Generously salt the water when boiling the potatoes. This seasons them from the inside out and enhances their flavor.
- Don’t Overcook: Cook the potatoes until they are fork-tender but not falling apart. Overcooked potatoes will absorb too much water and become gummy.
- Warm the Milk/Cream and Butter: Warming the milk or cream and melting the butter before adding them to the potatoes helps them incorporate more easily and prevents the potatoes from cooling down too quickly.
- Use a Potato Ricer or Masher: For the smoothest mashed potatoes, use a potato ricer or a potato masher. Avoid using a blender or food processor, as these can overwork the potatoes and make them gummy.
- Taste and Adjust: Taste the mashed potatoes after adding the Boursin and other ingredients and adjust the seasoning as needed. Don’t be afraid to add more salt, pepper, or even a little garlic powder to enhance the flavor.
- Gentle Mixing: Overmixing develops the gluten in the potatoes, leading to a gluey texture. Mix until just combined.
Storage & Reheating
Storage: Leftover Boursin mashed potatoes can be stored in an airtight container in the refrigerator for up to 3-4 days. The high dairy content means they shouldn’t sit out too long.
Reheating: The best way to reheat mashed potatoes is gently on the stovetop. Add a splash of milk or cream to loosen them up and prevent them from drying out. Heat over low heat, stirring frequently, until warmed through. You can also microwave them in short intervals, stirring in between, but be careful not to overheat them. Avoid reheating multiple times, as this can affect the texture and flavor.

Yukon Gold potatoes are my go-to for their creamy texture and naturally buttery flavor. Russet potatoes are also a good option if you prefer a lighter, fluffier mash. Red potatoes can be used, but they have a waxier texture and won’t be as fluffy. Ultimately, it’s a matter of personal preference!
