Ingredients You’ll Need
- 3 pounds russet or Yukon Gold potatoes: These potatoes are perfect for mashing due to their starchy texture, which yields a fluffy end result. You can substitute with other varieties like red potatoes, but they might be a bit less creamy.
- 6 tablespoons butter: Adds richness and enhances the creamy texture. For a lighter option, you can use olive oil but it’ll alter the flavor.
- ⅓ cup milk: Whole milk is recommended for creaminess, but any kind of milk works; just be aware it might impact the final texture.
- 3 cloves garlic (crushed): Adds a fragrant aroma and depth of flavor. Feel free to adjust based on your love for garlic!
- ⅛ teaspoon ground nutmeg: A pinch really enhances the overall taste. If you don’t have nutmeg, a bit of freshly ground black pepper is a great alternative.
- Salt & pepper (to taste): Essential for balance. I usually start with about ½ teaspoon of sea salt.
- 1 cup full-fat sour cream: Give your mashed potatoes that velvety, tangy flavor. You could swap it for Greek yogurt for a lighter yet still creamy alternative.
- 2 tablespoons chopped chives (or finely chopped green onion, optional): These add a pop of color and oniony bite, making them both tasty and pretty.
How to Make Sour Cream Mashed Potatoes
- Cook the potatoes: Begin by cutting the peeled potatoes into chunks and placing them in a large pot. Cover the bottom of the pot with about an inch of salted water, cover, and bring to a boil. Once boiling, reduce the heat and let the potatoes simmer until fork-tender—this usually takes around 10-15 minutes.
- Prep the milk mixture: While the potatoes are cooking, in a small saucepan, combine the butter, milk, crushed garlic, nutmeg, salt, and pepper. Heat over medium heat until the mixture is steaming hot and the butter has fully melted; this will infuse the flavors as it blends with the potatoes.
- Drain the potatoes: Once fork-tender, carefully drain the potatoes. Return them to the pot and place over the lowest heat for about one minute to steam off any excess moisture—this keeps the mashed potatoes from being watery.
- Mash the potatoes: With a potato masher, mash the potatoes until they’re just broken up. Avoid over-mashing to keep a lovely, chunky texture.
- Add milk and sour cream: Remove the garlic from the milk mixture and gradually incorporate it into the potatoes with your masher. Once combined, gently fold in the sour cream. If you want an even richer texture, you can adjust the amount of milk and sour cream to suit your taste.
- Serve immediately: Transfer to a serving bowl, garnish with chives or green onions if desired, then enjoy!
Storing & Reheating
To store sour cream mashed potatoes, let them cool to room temperature before transferring to an airtight container; they will last in the fridge for about three days. If you want to store them longer, consider freezing them in a freezer-safe container for up to three months. When you’re ready to enjoy them again, thaw overnight in the fridge and reheat on the stove over low heat, adding a splash of milk to restore that creamy consistency.
Chef’s Helpful Tips
- Avoid overcooking the potatoes; they shouldn’t fall apart. Just cook until fork-tender for the best texture.
- For extra creamy results, use room temperature milk and butter.
- If your mashed potatoes are too thick, add a bit more milk or sour cream until you reach your desired consistency.
- Try blending the garlic into the potatoes instead of removing it for a stronger flavor, if you prefer.
- Want to get ahead? You can make these a day in advance; just reheat with a splash of milk and stir well.
