Family Favorite: This recipe has been tested and loved by home cooks across generations. It’s simple enough for beginners but impressive enough for a festive holiday table.
Ingredients You’ll Need
- 3 pounds of mixed potatoes (Russets and Yukon Golds are best), peeled and cut into 1-inch pieces
- Kosher salt, to taste
- ½ cup whole milk
- ¾ cup (1½ sticks) unsalted butter, plus 2 tablespoons for topping
- ½ cup sour cream, at room temperature
- Freshly ground black pepper, to taste
- Fresh parsley, chopped, for garnish
Why This Combo Works: Russet potatoes give that fluffy, airy texture, while Yukon Golds add a rich, buttery flavor. Whole milk and butter create creaminess, and sour cream adds a tang that balances the richness beautifully.
Step-by-Step Instructions
- Boil the Potatoes: Place the peeled and chopped potatoes in a large pot. Cover with cold water and add a generous pinch of salt. Bring to a boil and cook for 15–20 minutes, until fork-tender.
- Drain and Dry: Drain the potatoes well, then return them to the pot for a minute to let any remaining moisture evaporate.


- Mash: Using a potato masher, ricer, or handheld mixer, mash the potatoes until smooth and fluffy.
- Warm the Dairy: In a small saucepan over medium heat, melt ¾ cup of butter in the milk. Do not boil—just heat until the butter melts completely.
- Combine: Pour the milk-butter mixture into the potatoes and stir until creamy.


- Add Sour Cream: Mix in sour cream, then season with salt and freshly cracked black pepper.
- Finish & Serve: Transfer to a serving bowl, top with the remaining butter, and sprinkle with fresh parsley for color and flavor.
Expert Tips for the Best Thanksgiving Mashed Potatoes
- Start with cold water: This helps the potatoes cook evenly and prevents the outsides from getting mushy.
- Warm your milk and butter: Cold dairy can stiffen the potatoes, making them less creamy.
- Avoid overmixing: Overworking the potatoes can make them gummy. Mash gently until smooth.
- Add garlic or herbs: For an extra Thanksgiving twist, simmer a few garlic cloves in the milk and butter before adding them to the potatoes.
Serving Suggestions
Mashed potatoes are a classic Thanksgiving side dish that pairs beautifully with just about everything on your holiday table. Serve them beside roasted turkey, gravy, stuffing, and cranberry sauce for a traditional spread. For a fresh, colorful balance, try pairing them with seasonal salads like:
- Roasted Sweet Potato Salad with Feta
- Pear Salad Recipe for Thanksgiving
- Creamed Brussels Sprouts Recipe
If you’re planning your full Thanksgiving menu, these dishes will complement your mashed potatoes beautifully, adding brightness and texture to your table.
Make-Ahead and Storage Tips
Make Ahead: Prepare your mashed potatoes up to one day before Thanksgiving. Let them cool completely, then store them in an airtight container in the refrigerator.
Reheat: Warm gently on the stovetop over low heat, adding a splash of milk or butter to bring back that creamy texture. You can also reheat in the oven (covered with foil) at 350°F for 20–25 minutes.
Leftovers: Store any leftovers for up to four days. You can use them to make potato croquettes, mashed potato waffles, or even loaded potato bowls with cheese.
