3lbYukon Gold potatoesor Russets, peeled if you want extra-smooth
1 1/2teaspoonkosher saltplus more to taste
6tablespoonssalted butterdivided (plus more for serving)
5.2ozBoursin Garlic & Fine Herbs1 package
3/4cupbuttermilkwarmed (plus more as needed)
1/4cupsour cream or cream cheeseoptional, for extra richness
Freshly ground black pepperto taste
Chives or parsleyfor topping (optional)
Instructions
Cut potatoes into 1 1/2–2 inch chunks. Add to a large pot and cover with cold water by about 1 inch. Salt the water (use the 1 1/2 tsp). Bring to a boil, then reduce to a steady simmer and cook 12–18 minutes, until very tender (a knife should slide in with no resistance).
Drain well, then return potatoes to the hot pot. Set over low heat for 1–2 minutes, stirring gently, to evaporate excess moisture.
Remove from heat. Mash with a potato masher for rustic potatoes, or run through a ricer for extra smooth potatoes.
Add 4 tablespoons butter and let it melt. Stir in Boursin until creamy. Slowly pour in warmed buttermilk, stirring until you reach your desired texture. Add optional sour cream or cream cheese, if using.
Taste and add more salt and black pepper. Top with remaining butter and chives or parsley, if you like.
Notes
For the fluffiest texture, don’t skip the step where you return the drained potatoes to the hot pot for 1–2 minutes to steam off excess moisture.
Warm the buttermilk before adding—cold liquid can make mashed potatoes stiff and cool them down fast.
Add the buttermilk gradually until you reach your ideal consistency (thick and scoopable or soft and swirly).
Yukon Golds make naturally creamy mashed potatoes; Russets make them extra fluffy. A 50/50 blend is also fantastic.
Avoid overmixing—stir just until everything is combined to keep the texture light, not gummy.
