The Secret to Incredibly Creamy Buttermilk Mashed Potatoes (No Cream Needed!)

Mashed potatoes are a quintessential comfort food, but achieving that perfect balance of creamy texture and rich flavor without excessive butter or heavy cream can be a challenge. For years, I sought a recipe that delivered on taste and texture while offering a slightly healthier profile. My journey took an unexpected turn after encountering a captivating image in Yotam Ottolenghi’s Simple—a platter of “aromatic olive oil mash” that was both visually stunning and incredibly inspiring. While Ottolenghi’s recipe, with its garlic-infused olive oil, thyme, mint, and lemon zest, certainly sounded exquisite, it sparked a different idea in my culinary mind.

Instead of following Ottolenghi’s path directly, I decided to revisit a classic: Sally Schneider’s renowned buttermilk mashed potatoes from A New Way to Cook. To elevate this already fantastic base, I combined it with a vibrant scallion-cilantro “sizzle”—a flavor-packed infusion I typically use in my homemade ranch dip. The result? A revelation that has forever changed how I view and prepare mashed potatoes.

As Ina Garten famously asks, “How bad can that be?” Friends, the answer is: not bad at all! These buttermilk mashed potatoes are nothing short of spectacular. They are not only visually appealing, with their swooshed peaks and valleys ready to cradle a flavorful topping, but they are also incredibly delicious. The buttermilk lends an irresistible creaminess and a subtle, tangy brightness that distinguishes them from traditional versions. When combined with the aromatic herb-and-chili infused olive oil, they become a vibrant, spicy, and utterly unforgettable side dish. You’ll be amazed at how rich and satisfying they taste, especially considering the minimal amount of fat used.

The Magic of Sally Schneider’s Buttermilk Mash: Healthier & Tastier

If you’re new to Sally Schneider’s approach, prepare to be impressed. Her recipes are known for their reliance on bold flavors and clever techniques over excessive enrichment. This buttermilk mashed potato recipe is a prime example. It masterfully achieves a luxurious texture and deep flavor using whole milk buttermilk, which offers a natural creaminess with significantly less fat than heavy cream or even whole milk. The buttermilk’s subtle acidity also adds a wonderful complexity, cutting through the richness of the potatoes without making them taste overtly sour.

Another brilliant technique involves using some of the reserved potato-cooking liquid to thin the mash as needed, ensuring perfect consistency while adding back some of the potato’s natural starchiness for a cohesive texture. And here’s the kicker: a mere tablespoon of butter is added only after the potatoes have absorbed the liquids. Schneider explains that by adding the butter at the very end, “the butter stays on the surface of the potatoes, its flavor readily discernible, imparting a truly rich finish.” This thoughtful timing maximizes the butter’s impact, giving the illusion of a much richer dish than it actually is. Every time I make these, I’m genuinely astonished by their decadent taste despite the absence of cream and minimal butter.

While the herb-infused olive oil has become a non-negotiable addition for me, I often spoon it over only half of the potatoes. This thoughtful consideration ensures there’s a plain option for children or any mashed potato purists at the table, allowing everyone to enjoy their preferred style. It’s a versatile recipe that caters to different palates.

Variations to Elevate Your Mash: Herby Sizzle & Roasted Garlic

Beyond the simple buttermilk mash, this recipe offers exciting variations. My absolute favorite, as mentioned, is the herby scallion-cilantro sizzle. This vibrant topping adds a fresh, aromatic kick with a hint of chili, transforming the humble mashed potato into something extraordinary. The combination of fresh herbs, olive oil, and a touch of heat provides a delightful contrast to the creamy potatoes.

Another beloved variation featured in the recipe box below is the addition of roasted garlic. Roasting garlic mellows its pungent flavor, turning the cloves sweet, buttery, and caramelized. Squeezing these soft cloves into the purée introduces a subtle earthiness and a gentle sweetness that beautifully complements the tangy buttermilk. It’s a sophisticated touch that adds another layer of depth to an already fantastic dish.

Essential Tools for the Perfect Mash: Beyond the Food Mill

Before we delve into the step-by-step instructions, let’s talk about the unsung heroes of mashed potato making: the tools. For years, I believed a food mill or a ricer was indispensable for achieving the smoothest purée. While both certainly produce exceptional results, the process can be cumbersome. They often require extra bowls, potatoes tend to get stuck in their crevices, and cleaning them can be a chore. Plus, there’s the perennial challenge of simply finding them in a crowded kitchen!

Choosing the Best Tools for Mashed Potatoes

My latest addition, the potato masher pictured above, has been a game-changer. It’s incredibly efficient and has streamlined my mashed potato preparation significantly. Think of a potato masher in relation to a food mill much like an immersion blender relates to a food processor—it gets the job done effectively, perhaps not with the absolute microscopic perfection of a specialized tool, but certainly with greater ease and efficiency for everyday cooking.

A crucial word of caution for those tempted by modern appliances: avoid using a food processor for mashed potatoes. The intense whipping action of the blades over-processes the starches in the potatoes, leading to a gluey, gummy, and utterly unappetizing texture. Trust me, a simple potato masher or even a sturdy fork is preferable to a food processor in this instance. For truly smooth potatoes without the hassle, a traditional ricer or food mill can be used, but the potato masher offers the best balance of convenience and quality for home cooks.

How to Make Creamy Buttermilk Mashed Potatoes: A Step-by-Step Guide

Let’s get cooking! The process for these buttermilk mashed potatoes is straightforward, relying on simple steps to build incredible flavor and texture. For the best results, I highly recommend using Yukon Gold potatoes. Their waxy-starchy balance creates an ideal creamy consistency when mashed, unlike drier baking potatoes that can result in a grainy texture.

Step 1: Prepare Your Potatoes

Begin by gathering your potatoes. Yukon Golds are my go-to choice for their naturally creamy texture and buttery flavor. For this recipe, you’ll need approximately 1 3/4 pounds before peeling.

Peel the potatoes and chop them into roughly 2-inch chunks. Uniform pieces ensure even cooking, which is key to a consistent mash.

Place the chopped potatoes in a large pot and cover them with cold water. Starting with cold water allows the potatoes to cook more evenly from the outside in, preventing the exterior from becoming mushy while the interior remains hard. Add a generous amount of salt to the water—this seasons the potatoes from within.

Bring the water to a boil, then reduce the heat to a simmer and cook for about 45 minutes, or until the potatoes are fork-tender. It’s crucial to cook them until they are very soft but not falling apart. Before draining, make sure to reserve at least 1/4 cup, and ideally closer to a cup, of the potato cooking liquid. This starchy liquid is your secret weapon for achieving the perfect consistency later on.

Step 2: Dry and Mash the Potatoes

Once cooked, drain the potatoes thoroughly. Return them to the hot pot over low heat for a few minutes, stirring occasionally. This step is vital for drying out any residual moisture, which helps prevent a watery mash and allows the buttermilk and butter to be fully absorbed, leading to a creamier texture.

Remove the pot from the heat. Add the room temperature buttermilk, about 1/4 cup of the reserved cooking liquid, and season with freshly ground black pepper and a pinch of flaky sea salt. Room temperature buttermilk incorporates more smoothly without cooling down the potatoes too much.

Now, mash the potatoes until they are mostly smooth. For this, I absolutely love this potato masher. Its design makes quick work of lumps, creating a wonderfully uniform texture. Remember, over-mashing can lead to stickiness, so stop when they’re “mostly smooth.”

Once mashed, add a single tablespoon of unsalted butter and continue to beat the potatoes with the masher or switch to a wooden spoon or spatula for further mixing. This final addition of butter, as Sally Schneider teaches, rests on the surface, imparting its full flavor and contributing to that surprisingly rich finish. Taste and adjust seasoning with more salt and pepper as needed. If the potatoes are too thick, gradually add more reserved cooking liquid, a tablespoon at a time, until your desired consistency is reached. You can stop here for a classic, incredibly flavorful mash, or move on to the exciting variations!

Herby “Ranch” Mashed Potatoes: A Fresh and Spicy Upgrade

This “herby sizzle” is my absolute favorite way to enhance these mashed potatoes, bringing a vibrant, fresh, and slightly spicy kick. If you’ve ever made my homemade ranch dip, this process will feel wonderfully familiar.

Step 1: Gather Your Herbs

Grab your scallions and fresh cilantro. If cilantro isn’t your favorite, feel free to omit it or substitute with fresh parsley or chives for a milder flavor. The fresh herbs are crucial for that burst of flavor and color.

Step 2: Sizzle the Herbs

Thinly slice the scallions and finely chop the cilantro. Transfer them to a small skillet with a generous drizzle of good quality olive oil and a pinch of crushed red pepper flakes. The red pepper flakes add a subtle warmth that complements the fresh herbs beautifully.

Cook this mixture over medium heat, swirling occasionally, until the herbs begin to soften and sizzle audibly and visually. This gentle cooking process infuses the oil with the aromatic flavors of the scallions, cilantro, and chili. Season with a pinch of sea salt, then remove from heat.

Step 3: Serve with Sizzle

Transfer your creamy mashed potatoes to a serving dish. Using the back of a spoon, create inviting peaks and valleys in the potatoes—perfect little reservoirs for the herby oil. Generously spoon the sizzling herb mixture over the top, letting the infused oil pool enticingly in the crevices. For an extra flourish, crack a little more fresh black pepper and sprinkle a touch of flaky sea salt before serving. As a family tip, I often garnish only half of the potatoes this way, leaving the other half plain for younger diners or those who prefer a simpler mash.

How to Make Roasted Garlic Mashed Potatoes: A Sweet & Earthy Infusion

For a deeper, more mellow flavor profile, roasted garlic is an exquisite addition to these buttermilk mashed potatoes. Roasting transforms garlic from pungent to sweet and caramelized, adding a nuanced earthiness without any harsh bite.

Step 1: Prepare the Garlic for Roasting

Start with two whole heads of garlic. Trim away the very top portion of each head, just enough to expose the tips of the individual cloves.

Place each trimmed garlic head on its own small square of aluminum foil. Drizzle generously with olive oil over the exposed cloves. Next, curl up the sides of the foil to create a small enclosure, and pour about a tablespoon of water into each foil pouch. This steam helps the garlic cook evenly and prevents it from drying out. Seal the foil tightly to form a secure pouch, then transfer to a preheated 425ºF (220ºC) oven for 35-45 minutes.

Step 2: Caramelize and Combine

Once roasted, open the foil pouches to reveal beautifully caramelized, butter-soft garlic cloves. These are a true delicacy on their own, wonderful spread over warm toast or incorporated into various dishes. The aroma alone is heavenly!

Allow the garlic to cool slightly, then gently squeeze the soft cloves from their papery skins directly into your pot of mashed potatoes. Stir thoroughly to combine, ensuring the sweet, earthy notes of the roasted garlic are evenly distributed throughout the creamy mash. Taste and adjust seasoning as needed.

For an ultimate flavor explosion, you can even combine the best of both worlds: add the roasted garlic to your mashed potatoes, then top them with the vibrant herby sizzle. The sweet garlic, tangy buttermilk, and spicy herbs create a truly complex and satisfying experience.

The foundational recipe for these incredible mashed potatoes, including the ingenious roasted garlic variation, hails from Sally Schneider’s A New Way to Cook. This cookbook served as my culinary bible for many years, and its innovative yet practical approach to cooking continues to inspire me.

I genuinely believe these Creamy Buttermilk Mashed Potatoes will become a staple in your home, just as they have in mine. The incredible flavor, combined with the surprising lightness for such a creamy dish, makes them truly irresistible. I could, quite happily, devour this entire bowl:
