Southern Buttermilk Mashed Potatoes Ingredients
Crafting the perfect Southern buttermilk mashed potatoes begins with selecting the right ingredients. Each component plays a vital role in achieving that signature creamy texture and rich flavor. Here’s a breakdown of what you’ll need:
- Yukon Gold Potatoes: These are my top recommendation for their smooth, waxy flesh and inherent moisture content, which contribute to an incredibly creamy mash. However, you can also use russet potatoes for a fluffier, starchier result, or red potatoes for a similarly creamy outcome to Yukon Golds. The choice depends on your desired final texture, but for that super smooth Southern style, Yukon Golds or red potatoes are ideal.
- Broth: Using chicken or vegetable broth instead of plain water for boiling potatoes infuses them with an extra layer of savory flavor right from the start. This simple swap significantly elevates the overall taste of your mashed potatoes. Ensure you use enough to fully cover your potato chunks.
- Unsalted Butter: Essential for richness and flavor, butter melts into the hot potatoes, adding a luxurious mouthfeel. Feel free to adjust the amount to your personal preference for decadence.
- Plain Greek Yogurt or Sour Cream: This ingredient is key to achieving an unparalleled creaminess and adds a subtle tang that complements the buttermilk beautifully. Both options work wonderfully, so choose what you have on hand or prefer.
- Buttermilk: The star ingredient! Buttermilk introduces a delightful, subtle tang and helps create an incredibly creamy texture due to its lactic acid content. It’s what truly distinguishes Southern buttermilk mashed potatoes from other recipes, adding depth and a unique brightness.
- Onion Powder, Garlic Powder, Salt, and Freshly Ground Black Pepper: Potatoes can be quite bland on their own, making generous seasoning absolutely crucial. Onion and garlic powders provide a foundational savory base, while salt and pepper balance and enhance all the flavors. Don’t be shy with your seasoning – taste as you go and adjust. For an exciting twist, consider adding a pinch of smoked paprika, a dash of Cajun Seasoning, or Creole seasoning to introduce a hint of smoky heat and complex spice.
The Secret to Perfectly Creamy Mashed Potatoes
Achieving the perfect creamy consistency in your mashed potatoes isn’t just about the ingredients; it’s also about technique. The lactic acid in buttermilk reacts with the potato starches to break them down more effectively, resulting in a silkier texture compared to using regular milk or cream. Additionally, using warm buttermilk and butter ensures they seamlessly integrate into the hot potatoes without cooling them down, maintaining that desirable smooth, creamy consistency. Avoid using cold ingredients, as this can make your mashed potatoes stiff and less pliable, requiring more mashing and risking a gummy outcome. The goal is a light, airy, and uniformly creamy mash that melts in your mouth.
Avoid Over-Boiling for Fluffy Results
One of the most common pitfalls when making mashed potatoes is over-boiling. When potatoes cook for too long, they become waterlogged and mushy. This excessive moisture absorption leads to a soupy, unappetizing consistency rather than the desired fluffy, creamy texture. Instead of a light mash, you’ll end up with a watery blob that lacks structure and appeal. To prevent this, it’s crucial to keep a watchful eye on your potatoes, especially if cooking on the stovetop. They should be fork-tender, meaning a fork can easily pierce them without resistance, but not falling apart. Proper cooking ensures your potatoes are ready to be mashed into a beautifully smooth and fluffy side dish.
How to Make Southern Buttermilk Mashed Potatoes: Step-by-Step
Creating these delightful Southern buttermilk mashed potatoes is a straightforward process, ensuring a delicious result every time. For precise measurements and a full printable recipe, refer to the recipe card located at the bottom of this post.
- Prepare the Potatoes: Begin by peeling your Yukon Gold potatoes (or preferred potato variety) and cutting them into uniform 1-inch chunks. This ensures even cooking.
- Cook the Potatoes: Place the potato chunks in a large pot and cover them generously with chicken or vegetable broth. Bring the liquid to a rolling boil over high heat, then reduce the heat to a simmer. Continue to cook until the potatoes are perfectly fork-tender, typically 10-15 minutes.
- Drain and Dry: Carefully drain the potatoes, making sure to reserve about half a cup of the flavorful broth for later adjustments. Return the drained potatoes to the warm, empty pot and let them sit for a couple of minutes to steam off any excess moisture. This crucial step prevents watery mashed potatoes and concentrates their flavor.
- Initial Mash: Add the softened butter to the hot potatoes in the pot. Using a potato masher, gently mash the potatoes until they are mostly smooth, leaving a few small lumps if you prefer a slightly rustic texture.
- Incorporate Creaminess and Flavor: Stir in the plain Greek yogurt or sour cream, along with the warm buttermilk, onion powder, garlic powder, salt, and freshly ground black pepper. Continue to mash or stir gently until all ingredients are thoroughly combined and the mixture reaches a creamy, cohesive consistency.
- Adjust and Serve: If your mashed potatoes appear too thick for your liking, gradually add a splash of the reserved broth or a bit more warm buttermilk until you achieve your desired creamy texture. Taste the mashed potatoes and adjust the seasoning as needed with more salt, pepper, or other spices before serving them hot.
The Ultimate Side Dish: Pairings and Gravy Recipes

Instructions
Prep the Potatoes
- Cut the potatoes into chunks about an inch thick.
Stovetop Boil Method
- Add the potatoes to a large pot along with cold water or broth. Use enough to completely cover 1 inch above the potatoes.
- Place the pot on the stove on high and allow the liquid to come to a boil. When the liquid reaches boiling, reduce to medium-high. Cook the potatoes for 10-15 minutes until they are tender. Pierce with a fork to check.
- Drain the excess liquid from the pot, reserving some broth if desired.
Instant Pot Potatoes Method
- Place the potatoes in the Instant Pot with enough broth or water to completely cover them. (No need to go an inch above).

Notes
To add an extra layer of flavor, consider incorporating smoked paprika, Cajun Seasoning, or Creole seasoning. These spices introduce a delightful warmth and complexity.
Be vigilant about not over-boiling your potatoes. Overcooked potatoes absorb too much liquid, resulting in a soupy, gummy texture instead of the desired fluffy mash. Cook until just fork-tender.
If buttermilk isn’t available or preferred, you can substitute it with an equal amount of whole milk, heavy cream, or a half-and-half mixture for a rich, creamy consistency.

Frequently Asked Questions and Pro Tips for Mashed Potatoes
Absolutely! Buttermilk mashed potatoes are excellent for making ahead. Prepare and mash them as directed, then allow them to cool completely before transferring them to an airtight container and storing them in the refrigerator. When you’re ready to serve, gently reheat them on the stovetop over low heat, stirring frequently, or in the oven covered with foil. Incorporate a splash of warm buttermilk or a pat of butter during reheating to restore their creamy texture and ensure they taste as fresh and rich as when first made.
The key to incredibly creamy mashed potatoes lies in the combination of buttermilk and either sour cream or plain Greek yogurt, especially when using Yukon Gold potatoes. Buttermilk, with its lactic acid, helps break down potato starches more effectively, resulting in a wonderfully smooth and fluffy texture. Always ensure your dairy ingredients (buttermilk, yogurt/sour cream, and butter) are at room temperature or slightly warmed before adding them to the hot potatoes to prevent cooling and seizing, which can lead to a less creamy result.
This is entirely up to your personal preference and the type of potato used. The skin, particularly on red or Yukon Gold potatoes, contains beneficial nutrients and can add a rustic texture to your mashed potatoes. If you prefer a completely smooth and velvety mash, peeling is recommended. For a more wholesome, home-style feel, leaving the skin on is perfectly acceptable and delicious.
If buttermilk isn’t readily available, you can achieve a similar tang and creaminess using substitutes. You can use an equal amount of whole milk, heavy cream, or half-and-half. Alternatively, you can make your own “buttermilk” by adding one tablespoon of lemon juice or white vinegar to a cup of regular milk (dairy or non-dairy), letting it sit for 5-10 minutes until it slightly curdles, then using it in the recipe. For more detailed instructions on substitutions, you can read about How to Substitute Buttermilk.
Gummy mashed potatoes are typically a result of overworking the potatoes. When potatoes are mashed too vigorously or for too long, their starches are released and become glue-like. To prevent this, mash only until the desired consistency is achieved, and avoid using electric mixers unless specifically designed for potatoes, as they can easily over-process. If your potatoes are already gummy, unfortunately, it’s very difficult to reverse. The best approach is prevention: cook until just tender and mash gently.
Lumpy mashed potatoes usually indicate that the potatoes weren’t cooked long enough to become uniformly tender or weren’t mashed thoroughly enough. To remedy this, ensure your potatoes are always cooked until completely fork-tender before mashing. If you find lumps after mashing, you can try passing the potatoes through a potato ricer or food mill for an ultra-smooth consistency, or simply return them to low heat on the stovetop with a little extra warm buttermilk or butter and continue mashing gently until the lumps dissolve.
Leftover Southern buttermilk mashed potatoes can be stored in an airtight container in the refrigerator for 3-4 days. Ensure they are cooled completely before sealing and refrigerating to maintain their quality and prevent bacterial growth. Reheat gently, as described in the “make ahead” tip, adding a little extra liquid or butter if they seem dry.
Yes, you can freeze these mashed potatoes! Store them tightly sealed in a freezer-safe container or bag. For best quality, consume them within one month, as prolonged freezing can lead to freezer burn and the formation of ice crystals, which might affect their texture. To defrost, transfer them to the refrigerator overnight. Reheat gently on the stovetop or in the oven, adding a splash of warm buttermilk or broth to restore creaminess.
Variations, Add-ins, and Substitutions
While this classic Southern buttermilk mashed potato recipe is perfect as is, it also serves as a fantastic base for creativity. Feel free to customize your mash with these delicious add-ins and substitutions to suit your taste or occasion:
- Crumbled Bacon: For a smoky, salty crunch, fold in crispy crumbled bacon just before serving.
- Cream Cheese: A few ounces of softened cream cheese can be added during mashing for an even richer, tangier, and more decadent texture.
- Shredded Parmesan Cheese: Stir in some freshly grated Parmesan for a salty, umami kick.
- Shredded Cheddar Cheese: Melt in some sharp cheddar for a cheesy twist, perfect for a heartier side.
- Fresh Herbs: Finely chopped fresh parsley, chives, or green onions can be stirred in for a burst of fresh flavor and color.
- Roasted Garlic: For a deeper, sweeter garlic flavor, mash in a head of roasted garlic with the potatoes.
- Spicy Kick: Add a pinch of cayenne pepper, red pepper flakes, or a dash of your favorite hot sauce for a subtle warmth.
- Caramelized Onions: Fold in sweet, savory caramelized onions for an elegant and flavorful upgrade.
