The Secret Ingredient: Boursin Cheese
At the heart of this extraordinary recipe lies Boursin cheese. But what exactly is Boursin, and why is it so perfect for mashed potatoes? Boursin is a brand of Gournay cheese, a soft, creamy, and spreadable fresh cheese originally from Normandy, France. It’s known for its rich, tangy flavor and smooth texture, often blended with garlic, herbs, and spices. While traditionally served on its own or with crackers, Boursin’s melt-in-your-mouth quality and vibrant flavors make it an exceptional cooking ingredient. When incorporated into mashed potatoes, it doesn’t just add a creamy element; it infuses them with a gourmet complexity, providing notes of garlic, chives, and parsley that elevate the entire dish without needing a separate herb garden.
Essential Ingredients for Perfect Creaminess
Crafting the perfect Boursin mashed potatoes begins with selecting the right ingredients. Each component plays a vital role in achieving that rich, creamy texture and unforgettable flavor:

Main Ingredients:
- Potatoes: For the best mashed potatoes, I highly recommend using russet potatoes. Their high starch content and low moisture make them incredibly sturdy and fluffy when mashed, absorbing butter and cream beautifully without becoming gummy. Yukon Gold potatoes are another excellent option, offering a naturally buttery flavor and creamy texture. While red potatoes can work, they tend to be waxier and may result in a slightly less fluffy mash.
- Boursin Cheese: This is the star of the show! You can use whatever Boursin flavor you love most. My personal favorite is the classic Garlic & Fine Herbs for its robust, aromatic profile, but Boursin offers a delightful array of flavors, including Black Truffle, Caramelized Onion, and even a dairy-free option, allowing for wonderful customization.
- Butter: A touch of butter is essential for richness and flavor. Although Boursin itself is quite fatty and flavorful, the added butter contributes to the luxurious mouthfeel. Both salted and unsalted butter are fine; just be mindful of adjusting the added salt accordingly.
- Heavy Cream (or Milk): This is the ultimate secret to achieving that coveted silky, smooth texture. Heavy cream provides unparalleled richness. However, if you prefer a slightly lighter result or simply don’t have heavy cream on hand, whole milk or half-and-half can be successfully substituted.
- Salt & Pepper: A foundational seasoning for any savory dish. I recommend starting with a small amount and then adjusting to taste. Freshly ground black pepper always makes a difference, adding a subtle warmth and aroma.
Recommended Equipment:
Having the right tools can make the mashing process smoother and more enjoyable:
- Large Pot: You’ll need a pot spacious enough to comfortably boil 2 ½ pounds of potatoes without overcrowding. I find an Amazon Basics 6 Quart Dutch Oven works perfectly, providing ample room for boiling and mashing.
- Potato Masher: A good potato masher is key. I recently switched to this OXO potato masher and love its efficiency. For the absolute smoothest, restaurant-quality mash, a potato ricer is the gold standard, though it can be a bit less practical for everyday use.
- Silicone Spatula: Ideal for gently folding in ingredients, scraping down the sides of the pot, and ensuring everything is thoroughly combined. I use this one from OXO.
- Hand Mixer (Optional): For an ultra-smooth, lump-free consistency, a hand mixer can be a game-changer, especially if you’re aiming for a whipped potato texture.
Step-by-Step Instructions: How to Make Boursin Mashed Potatoes
These Boursin Mashed Potatoes have quickly become our favorite way to prepare a classic side dish, transforming it into something truly special. Best of all, the process is straightforward enough for even a busy weeknight. Follow these simple steps for perfectly creamy and flavorful results:

Step 1: Prepare the Potatoes. Peel the russet potatoes and cut them into uniform ¾-inch slices or 1-inch cubes. Uniform size ensures even cooking.

Step 2: Boil Until Tender. Place the potato pieces in a large pot and cover them with cold water. Bring the water to a rolling boil over high heat, then reduce heat slightly to maintain a vigorous simmer. Cook for 18-22 minutes, or until the potatoes are fork-tender and can be easily pierced with a knife.

Step 3: Drain and Add Butter. Carefully drain the cooked potatoes using a colander. Return the drained potatoes to the empty hot pot (off the heat) and immediately add 4 tablespoons of butter. The residual heat in the pot will help melt the butter and begin to dry out the potatoes.

Step 4: Mash and Incorporate. Begin mashing the potatoes and butter together over very low heat. This gentle heat helps evaporate any remaining moisture, resulting in fluffier mashed potatoes. Continue mashing until the potatoes are broken down and the butter is fully incorporated.

Step 5: Add Boursin and Cream. Remove the pot from the heat. Break a regular-sized round of Boursin cheese (150g or 5.2oz) into 4-6 pieces and add them to the mashed potatoes. Pour in the heavy cream (or milk), salt, and pepper.

Step 6: Mix Until Smooth. Stir everything together vigorously with a silicone spatula or a sturdy wooden spoon. Continue mixing until the creamy Boursin cheese has fully melted and is incorporated, and the potatoes are smooth and luscious. Taste and adjust seasonings as needed, adding more salt or pepper to your preference.
Pro Tip for an Ultra-Smooth Texture: For the silkiest, most luxurious mashed potatoes that practically melt in your mouth, use a hand mixer to blend everything together after adding the Boursin and cream. This will whip air into the potatoes and ensure no lumps remain, creating an irresistibly smooth consistency.
Instant Pot Method for Quick Boursin Mashed Potatoes
Short on time? The Instant Pot is your best friend for speeding up the cooking process without sacrificing flavor or creaminess. Here’s how to adapt this Boursin mashed potatoes recipe for your pressure cooker:
- Peel and slice your potatoes as directed in the main recipe.
- Place the potato slices in your Instant Pot with 2 cups of water.
- Secure the lid and set the Instant Pot to cook on high pressure. Cook potato slices for 8 minutes. If using 1-inch cubes, cook for 6 minutes.
- Once cooking is complete, perform a quick pressure release.
- Carefully drain the potatoes and return them to the Instant Pot.
- Select the “Sauté” function on your Instant Pot. Add the butter and mash the potatoes over the low heat, allowing any remaining steam to escape. This helps dry them out for a better texture.
- Turn off the Instant Pot’s “Sauté” function. Add the Boursin cheese, heavy cream, salt, and pepper.
- Mix everything together thoroughly until the Boursin is melted and the potatoes are smooth and creamy.
- Serve immediately with additional butter and chives, if desired.

Serving Suggestions and Pairings
These creamy Boursin mashed potatoes are incredibly versatile and pair beautifully with a wide array of main courses. Their rich, savory profile complements both simple and elaborate meals. Here are some ideas for serving them:
- Holiday Roasts: They are an absolute showstopper alongside roasted turkey, prime rib, or glazed ham for Thanksgiving, Christmas, or Easter.
- Comfort Food Classics: Serve them with roasted chicken, meatloaf, or beef stew for a comforting and satisfying meal.
- Steak and Seafood: The creamy texture and herb notes make them an excellent accompaniment to pan-seared steak, grilled salmon, or baked cod.
- Vegetarian Options: Pair them with roasted vegetables, mushroom Wellington, or a hearty lentil loaf for a complete vegetarian feast.
- Garnish Ideas: Enhance their visual appeal and add an extra layer of flavor by topping them with a pat of melted butter, a sprinkle of fresh chopped chives, minced parsley, or even a few crispy bacon bits.
Make Ahead & Storage Tips
One of the many advantages of these Boursin mashed potatoes is how well they hold up to being made in advance, thanks to their high fat content. This makes them an ideal choice for holiday meal prep or busy schedules, ensuring you can enjoy a delicious side dish without last-minute stress.
Storing Leftovers:
- Transfer any leftover Boursin mashed potatoes to an airtight container.
- Store them in the refrigerator for up to 3 days to maintain optimal freshness and flavor.
Reheating for Optimal Flavor:
- Microwave Method: For individual portions, reheat in the microwave in 30-second to 90-second intervals, stirring between each, until thoroughly warmed through. Add a splash of milk or cream if they seem a little dry.
- Oven Method: For larger quantities or a crispier top, transfer portions to a baking dish. Add a few pats of butter and/or a tablespoon or two of water or milk over the top to prevent drying. Cover loosely with foil and heat in a preheated oven at 350ºF (177ºC) for 15-30 minutes, or until hot and bubbly. Remove foil for the last 5 minutes if you desire a slightly browned crust.
Prepare in Advance:
Making these mashed potatoes ahead of time is a fantastic strategy for entertaining or simplifying weeknight dinners. The generous amount of Boursin and butter helps them retain their creamy texture much better than traditionally prepared potatoes.
- Prepare the Boursin mashed potatoes exactly as directed in the instructions.
- Spread them evenly into a deep 8×8-inch (20x20cm) baking dish. If you’re doubling the recipe, a 9×13-inch (23x33cm) baking dish will be perfect.
- Allow the mashed potatoes to cool completely to room temperature. This is crucial for proper storage and reheating.
- Once cooled, top the surface with a few additional slices or pats of butter. This helps keep them moist during storage and reheating.
- Wrap the baking dish tightly with plastic wrap, then cover with aluminum foil. Refrigerate for up to 48 hours.
- To reheat, bake in a preheated 350ºF (177ºC) oven for 20-30 minutes, or until they are hot, bubbly, and fragrant.
Top Tip for Make-Ahead Perfection: To ensure the best results and prevent temperature shock on your baking dish (which can cause it to crack), allow the cold baking dish to sit at room temperature for about 1 hour before placing it in the hot oven. Alternatively, you can place the cold baking dish directly into a cold oven and let it gradually warm up as the oven preheats. Both methods help prevent uneven heating and potential cracking.

Creative Variations to Explore
While the classic Boursin mashed potatoes are undeniably delicious, don’t hesitate to get creative with these exciting variations:
- Buttermilk Tang: For a delightful, subtle tangy flavor that cuts through the richness, try substituting half or all of the heavy cream with buttermilk. It adds a wonderful depth!
- Loaded Mash: Transform these into fully loaded mashed potatoes by stirring in cooked, crumbled bacon, shredded cheddar cheese (or another favorite), and a dollop of sour cream (or additional gournay cheese) just before serving. A sprinkle of green onions would be a great finishing touch.
- Roasted Garlic Infusion: Roast a head of garlic until soft and caramelized, then mash the cloves into the potatoes along with the Boursin. The sweet, mellow flavor of roasted garlic adds an incredible dimension.
- Different Boursin Flavors: Experiment with the wide variety of Boursin flavors available. While Garlic and Herb is a classic, consider Black Truffle for an earthy elegance, Caramelized Onion for a sweet and savory twist, or even Cranberry & Pepper for a festive holiday version.
- Fresh Herb Boost: Beyond chives, consider folding in other fresh herbs like finely chopped rosemary, thyme, or dill for different aromatic profiles.
- Spicy Kick: For those who love a bit of heat, a pinch of red pepper flakes or a dash of hot sauce can add a surprising and welcome kick.
Smart Substitutions for Every Need
Sometimes you need to make a swap, and that’s perfectly fine! Here are some effective substitutions to help you make this recipe work with what you have on hand or to accommodate dietary preferences:
- Boursin Alternatives: If Boursin cheese isn’t available, you can substitute it with 4 ounces of plain or garlic-and-herb cream cheese. For a tangier flavor, sour cream or full-fat Greek yogurt can work, though they may not melt quite as smoothly. Any other spreadable, soft cheese with a savory profile could also be an interesting experiment.
- Heavy Cream Swap: The heavy cream can be successfully swapped for whole milk, half-and-half, or even unsweetened canned coconut milk for a subtly different flavor and richness.
- Dairy-Free Option: To make these mashed potatoes entirely dairy-free, use the dairy-free Boursin alternative (if available) or your favorite vegan cream cheese. Substitute the butter with your preferred vegan butter, and the heavy whipping cream with a good quality dairy-free cream alternative or full-fat canned coconut milk. Ensure all other ingredients are dairy-free as well.

Frequently Asked Questions (FAQs)
- Can I use different types of potatoes for this recipe?
- While russet potatoes are highly recommended for their fluffy texture, Yukon Gold potatoes are an excellent alternative for a creamier mash. Red potatoes can be used but may result in a slightly waxier texture.
- Is Boursin cheese difficult to find?
- Boursin cheese is widely available in most major grocery stores, usually found in the specialty cheese or dairy section alongside other soft cheeses or cream cheese.
- Can I freeze Boursin mashed potatoes?
- Mashed potatoes with a high fat content, like these, tend to freeze better than traditional ones. Place cooled mashed potatoes in an airtight, freezer-safe container or bag. They can be frozen for up to 1 month. Thaw overnight in the refrigerator, then reheat gently in the microwave or oven, adding a splash of milk or cream if needed.
- How can I make my mashed potatoes extra smooth?
- For an exceptionally smooth texture, use a potato ricer instead of a masher. Additionally, incorporating the ingredients with a hand mixer after initial mashing will whip the potatoes to a light, airy, and lump-free consistency.
- What’s the best way to prevent gummy mashed potatoes?
- The key is not to overwork the potatoes once they’ve been mashed. Over-mashing or over-processing potatoes can release too much starch, leading to a gummy texture. Also, ensuring the potatoes are adequately drained and “dried” (by briefly returning them to the hot pot) before adding liquids helps.
