Step-by-Step Instructions
Step 1 — Prep the Potatoes
Peel 2 pounds of Yukon Gold or Russet potatoes and cut them into uniform 1-inch chunks. This ensures even cooking and a consistent texture in your Buttermilk Mashed Potatoes.
Place the cut potatoes in a large pot and cover with cold water by at least an inch. Adding a generous pinch of salt to the water now seasons the potatoes from the inside out.
Step 2 — Boil Until Tender
Bring the pot to a boil over high heat, then reduce to a steady simmer. Cook for 15–20 minutes, or until the potatoes are fork-tender. A fork should slide in and out easily without resistance.
Avoid overcooking, as waterlogged potatoes can become gluey. Drain them thoroughly in a colander and let them steam dry for a minute to remove excess moisture.
Step 3 — Heat the Buttermilk and Butter
While the potatoes are draining, gently warm 1 cup of buttermilk and ½ cup (1 stick) of unsalted butter in a small saucepan over low heat. Do not boil; you just want to take the chill off.
Warming the dairy prevents the potatoes from cooling down and becoming gummy when mixed. The butter should be mostly melted.
Step 4 — Rice or Mash the Potatoes
For the smoothest Buttermilk Mashed Potatoes, pass the hot, drained potatoes through a potato ricer back into the warm pot. If you don’t have a ricer, use a potato masher until no large lumps remain.
Avoid using a food processor or blender, as over-mixing can release too much starch and create a gluey texture.
Step 5 — Incorporate the Buttermilk Mixture
Pour about half of the warm buttermilk and butter mixture over the riced potatoes. Use a wooden spoon or rubber spatula to fold it in gently until just combined.
Gradually add the remaining liquid until you reach your desired consistency. The Buttermilk Mashed Potatoes should be creamy and smooth.
Step 6 — Season and Finalize
Season the mashed potatoes generously with salt and freshly ground black pepper to taste. For extra flavor, you can add a pinch of garlic powder or some freshly chopped chives.
Give the Buttermilk Mashed Potatoes one final gentle stir, then serve immediately while hot and creamy.

Common Mistakes to Avoid
- Mistake: Using the wrong potato type, like waxy red potatoes. Fix: Choose high-starch russets or Yukon Golds for a fluffier, creamier texture.
- Mistake: Adding cold buttermilk and butter directly from the fridge. Fix: Warm dairy ingredients slightly to prevent the potatoes from becoming gummy.
- Mistake: Overworking the potatoes in a food processor or blender. Fix: Mash by hand with a ricer or masher to avoid a gluey consistency.
- Mistake: Not seasoning the cooking water for the potatoes. Fix: Salt the boiling water generously to build flavor from the inside out.
- Mistake: Adding all the buttermilk at once without tasting. Fix: Incorporate it gradually and taste as you go to achieve the perfect tang and consistency.
- Mistake: Letting the cooked potatoes sit and cool before mashing. Fix: Mash them while hot for the best texture and to absorb the buttermilk and butter more easily.
- Mistake: Skipping the step of draining potatoes thoroughly. Fix: Let them steam dry in the colander for a minute to prevent watery Buttermilk Mashed Potatoes.
- Mistake: Underseasoning the final dish, relying only on salt. Fix: Finish with freshly cracked black pepper and a pinch of white pepper for a flavor boost.
Storing Tips
- Fridge: Store your Buttermilk Mashed Potatoes in an airtight container for up to 5 days. Keep the refrigerator temperature at or below 40°F (4°C) for food safety.
- Freezer: Transfer the mashed potatoes to a freezer-safe container or heavy-duty freezer bag. They will keep well for up to 2 months.
- Reheat: Thaw frozen potatoes in the refrigerator overnight. Reheat in a saucepan over medium-low heat, stirring often, or in the microwave, until they reach an internal temperature of 165°F (74°C).
For best results, add a small splash of buttermilk or milk when reheating to help restore the creamy texture of your Buttermilk Mashed Potatoes.

FAQs
Can I make Buttermilk Mashed Potatoes ahead of time?
Yes, you can prepare them a day in advance. Store them in an airtight container in the refrigerator and reheat gently on the stovetop, adding a splash of buttermilk to restore creaminess.
What can I use if I don’t have buttermilk?
You can make a quick substitute by adding one tablespoon of lemon juice or vinegar to one cup of milk. Let it sit for 5-10 minutes until it thickens slightly before using in your Buttermilk Mashed Potatoes.
Why are my mashed potatoes gluey?
