Longhorn Mashed Potatoes Copycat Recipe: Buttery, Velvety Crowd-Pleaser With Secret Creaminess

This Longhorn Steakhouse mashed potatoes copycat recipe delivers the same velvety, buttery perfection you’d expect from their famous menu—creamy enough to melt in your mouth yet light enough to pair flawlessly with steak or chicken.

The secret lies in using skin-on Yukon Gold potatoes and a precise technique that balances richness without heaviness. I’ve recreated this dish after years of testing, ensuring every bite matches the restaurant’s signature texture.

The key to authentic Longhorn mashed potatoes starts with the potatoes themselves—never peel them, as the skin adds natural creaminess and structure.

After boiling, we drain and dry them thoroughly before blending with butter, cream, and a touch of salt, then finish with a gentle hand-mashing for that signature silky consistency. This method guarantees a smooth, lump-free result that’s far superior to boxed mixes.

What sets these apart is the buttery, velvety finish—achieved by incorporating cold butter and warm cream in stages, then folding in just enough to create a luxurious, clingy texture.

The final touch? A sprinkle of fresh chives or black pepper, because presentation matters just as much as taste. This recipe delivers restaurant-quality mashed potatoes at home, every time.

Perfect for holidays, steakhouse dinners, or family gatherings, these mashed potatoes scale effortlessly from side dishes to the centerpiece of any meal. The technique is foolproof, and the results are undeniably indulgent—just like the original. Let’s get started on recreating this Texas classic.

Ingredients for longhorn mashed potatoes copycat

Eight essential ingredients transform into Longhorn’s signature velvety mashed potatoes—rich yet light, with a secret buttery finish.

The Yukon Gold potatoes are non-negotiable—their waxy texture and natural creaminess replicate the restaurant’s signature mouthfeel. Whole Foods or local farmers' markets carry the freshest, but standard grocery stores stock them year-round. Look for potatoes with firm, unblemished skins and avoid those with sprouts, as they’ll affect flavor. The secret? Leave the skins on—they add body and prevent the mash from becoming gluey. For best results, use potatoes that weigh 3-4 pounds total to ensure a generous 6-serving batch with proper texture. If substituting, Russet potatoes work in a pinch but require careful drying to prevent grittiness.

No heavy cream? Whole milk plus 1 tbsp butter per cup mimics the richness, though texture will differ slightly. The unsalted butter must be cold when added—this creates the signature clingy texture. Plugrá or Land O’Lakes are reliable brands, but avoid salted varieties to control seasoning. Freshly ground black pepper is critical; pre-ground loses potency quickly. For extra depth, add granulated garlic (½ tsp) or a pinch of nutmeg (¼ tsp), though these aren’t in the original recipe. The chives should be added last—store them in a damp paper towel in the fridge for up to 5 days to preserve their vibrant color.

Potatoes keep 1 week in a cool, dark place (not the fridge) until ready to use. Once boiled, drain immediately and return to the pot—off-heat—to dry thoroughly for 5 minutes. This step eliminates excess moisture, which is key to that restaurant-quality silkiness. The finished mash holds in the fridge for 3 days but loses its velvety texture. For make-ahead convenience, par-cook the potatoes, then refrigerate the unmashed chunks in water. Reheat gently with a splash of milk before mashing. Freeze for up to 3 months by portioning into airtight containers with a layer of plastic wrap to prevent freezer burn.

Step-by-step instructions for Longhorn mashed potatoes

This is the exact method that delivers the signature Longhorn restaurant texture—silky, ultra-creamy, and loaded with buttery richness without a single clump.

Start by thoroughly rinsing the 3 lb Yukon Gold Potatoes under cold water to remove any dirt or debris. Peel them if desired, though leaving the skin on adds subtle earthiness and texture. Using a sharp chef's knife, cut the potatoes into even 2-inch chunks—this ensures uniform cooking time and prevents any undercooked or mushy pieces.

Transfer the potato chunks to a large pot and cover them with cold water by about 2 inches. Add the 1.5 tsp Diamond Crystal Kosher Salt to the water. Bring to a boil over medium-high heat, then immediately reduce to a gentle simmer. Cook until the potatoes are fork-tender, which typically takes 15-20 minutes. You'll know they're done when a knife slides in easily and the edges begin to pull away from the center.

Drain the potatoes completely in a colander, shaking gently to remove excess water. Return them to the now-empty pot and place it over low heat for 2-3 minutes. This step is crucial—it helps evaporate any remaining surface moisture, which prevents your mash from becoming watery. Leave the lid slightly ajar to allow steam to escape.

While the potatoes warm, prepare the dairy mixture. In a separate saucepan, warm the 1 cup Heavy Cream and 0.25 cup Whole Milk over medium heat until just steaming—do not boil. This gentle warming ensures the cream incorporates smoothly without curdling. If using, dissolve the 0.5 tsp Granulated Garlic in the warm cream for subtle depth, but omit if you prefer a classic flavor profile.

Using a potato masher or ricer, work in batches to break down the warm potatoes into rough chunks. The goal here is to create a slightly lumpy texture—this prevents the potatoes from becoming gluey when you add the dairy. Transfer the mashed potatoes to a large mixing bowl, leaving room for the butter and cream.

Add the 1 cup Unsalted Butter, cut into ½-inch cubes, to the warm potatoes. Using a wooden spoon or silicone spatula, fold the butter into the potatoes until fully melted and evenly distributed. This step is where the magic happens—the butter's fat coats each potato piece, creating that signature velvety mouthfeel. Gradually pour in the warmed cream mixture while folding continuously to combine.

Switch to a handheld immersion blender or stand mixer fitted with the paddle attachment. Blend the potatoes on low speed until completely smooth, scraping the sides of the bowl as needed to ensure no lumps remain. If using a stand mixer, blend for 1-2 minutes on low speed—high speed can overwork the potatoes and create a gummy texture. The result should be a silky, almost custard-like consistency.

Taste and adjust seasoning with additional Diamond Crystal Kosher Salt or Freshly Ground Black Pepper as needed. The potatoes should be rich but not overly salty—remember, the butter is already quite flavorful. For extra insurance against dryness, fold in the 0.25 cup Whole Milk if the mash appears slightly thick.

Transfer the mashed potatoes to a serving dish and smooth the surface with a spatula. For the signature Longhorn touch, gently press the 2 tbsp Fresh Chives into the top using the back of a spoon—this creates a beautiful marbled effect while adding a fresh, bright contrast to the rich potatoes. The chives should be finely chopped and evenly distributed for visual appeal.

Serve immediately while still warm. The potatoes should be light yet dense, with a luxurious mouthfeel that melts in your mouth. Each bite should deliver a perfect balance of buttery richness, creamy texture, and subtle seasoning. For best results, keep the dish covered until serving to maintain its velvety consistency.

Best sauces and condiments for these flavors

Buttery Cream Sauce

The foundation of Longhorn-style mashed potatoes is their ultra-creamy butter sauce, achieved by combining 1 cup cold unsalted butter with 1 cup warm heavy cream. I use Plugrá European-style butter because its higher fat content (82%) creates that signature clingy texture.

Warm the cream just until steaming—never boiling—to prevent curdling. Fold the butter into the warm potatoes in small batches while mashing to distribute the fat evenly. This two-stage method ensures each bite has that restaurant-quality richness without heaviness. 🧈

Garlic-Infused Cream

For an elevated twist, I infuse the warm cream with ½ tsp granulated garlic (like Garlic Express) for subtle depth. Simply dissolve the garlic powder in the warm cream before combining with the potatoes. This adds a sophisticated note that complements steakhouse meals beautifully.

If you prefer a more pronounced garlic flavor, minced fresh garlic works too—just sauté it briefly in butter first. The key is balance; too much garlic can overpower the delicate potato flavor. 🧄

Whole Milk Finish

For extra creaminess without altering the texture, I add ¼ cup whole milk during the final blending stage. This step prevents the mash from becoming too dense while maintaining that silky consistency. Use whole milk (3.25% fat) for the best results—it blends seamlessly without watering down the dish.

If you're watching calories, half-and-half works too, though the texture will be slightly lighter. Always add the milk last, after the butter and cream, to preserve the velvety mouthfeel. 🥛

Fresh Herb Garnish

The signature Longhorn touch is finely chopped fresh chives pressed into the surface. I use 2 tbsp chives because their mild onion flavor brightens the richness of the butter. For a bolder presentation, try crispy fried shallots or black peppercorn clusters.

Garnish just before serving to keep the herbs vibrant. Store-bought chives work in a pinch, but fresh chives from the market add a restaurant-quality finish. 🌿

Optional Truffle Oil

For a luxurious upgrade, drizzle ½ tsp white truffle oil over the finished mash. The earthy aroma pairs perfectly with steakhouse flavors. I recommend Truffle Shop brand for its pure, high-quality oil.

Add it last so the aroma doesn’t dissipate during cooking. A sprinkle of flaky sea salt enhances the truffle notes, creating a gourmet version of the classic dish. 💫
