Buttermilk Pumpkin Mashed Potatoes are a delightful twist on a classic side dish that brings a touch of autumn warmth to your table. The creamy texture of the mashed potatoes is enhanced by the subtle sweetness of pumpkin, while the tangy buttermilk adds depth and richness. A sprinkle of cinnamon and nutmeg infuses the dish with cozy spices, making it perfect for holiday gatherings or a comforting family meal. Serve it alongside roasted turkey or glazed ham for a festive feast, or enjoy it on its own as a satisfying treat.

I’ve had a fondness for instant mashed potatoes since my childhood. There’s something about their creaminess that can’t quite match the mashed potatoes my mom made from boiled ones. In this recipe, I use Idahoan Buttery Homestyle Mashed Potatoes, which evoke all the nostalgic feels from my younger days. No matter your preference, this recipe will certainly offer a delightful twist on a Thanksgiving classic.
7- Ingredients for these Creamy Buttermilk Pumpkin Mashed Potatoes

You will Need:
- 2 Packages of Idahoan Buttery Homestyle Mashed Potatoes or 4 pounds of Yukon Gold or russet potatoes, peeled and diced into 1-inch cubes
- Salt to taste
- 1 can of pumpkin puree (15 ounces), approximately 1⅔ cups
- 1¼ cups of buttermilk, brought to room temperature. (If you’re unable to find buttermilk, you can easily make your own! Simply add 1 tablespoon of lemon juice or vinegar to every 1 cup of milk. Allow the mixture to sit for 10 minutes.)
- 6 tablespoons of unsalted butter, melted and allowed to cool
- 1 tablespoon of fresh thyme
- ½ teaspoon of nutmeg
Directions:
- Prepare Mashed Potatoes. If you’re using Idahoan Buttery Homestyle Mashed Potatoes, simply follow the instructions provided on the package. Otherwise, place the potatoes in a large pot and cover them with one inch of water. Stir in one tablespoon of salt. Bring the water to a boil over high heat, then lower the heat to medium and let it simmer. Cook until the potatoes can be easily pierced with a paring knife or fork, which should take about 15 to 18 minutes.
- Combine Ingredients. In a bowl, mix together pumpkin, buttermilk, butter, thyme, and nutmeg; then set the mixture aside.
- Mash the Potatoes (Skip this step if using instant). Drain the potatoes, then place them back in the pot over low heat. With a potato masher, mash the potatoes until just a few small lumps are left.
- Combine all the ingredients thoroughly. Take the pot off the heat and incorporate the pumpkin mixture into the mashed potatoes. Using a rubber spatula, gently fold the ingredients together until they are just combined. Season the potatoes with salt and pepper before serving.
- Enjoy!
