The potatoes are non-negotiable here. Russets deliver that signature fluffiness—Yukon Golds work but lean slightly waxy. Look for firm, unblemished spuds at Whole Foods or your local market. The cream and butter should be full-fat; low-fat versions won’t emulate that velvety texture. I always grab Organic Valley heavy cream for consistent results.
No heavy cream? Half-and-half plus a splash of melted butter gets you close. Sour cream can be swapped for Greek yogurt (use full-fat to avoid tanginess). For a richer finish, crème fraîche works beautifully. The garlic is optional but recommended—skip it if you prefer a milder flavor. Fresh chives add a pop of color, but green onions work in a pinch.
Mashed potatoes are best served immediately, but they reheat well. Store in an airtight container for up to 4 days in the fridge. Reheat gently with a splash of milk to restore creaminess. For make-ahead, prep everything except the butter and cream, then finish just before serving.

Step-by-Step Instructions for Steakhouse-Style Creamy Mashed Potatoes
Achieve that signature velvety texture with this professional technique for luxurious results.
Step 1: Prepare and Boil the Russet Potatoes
Peel the 2 lb Russet Potatoes and cut them into even 1½-inch chunks. This uniform size ensures even cooking so all pieces reach the perfect doneness simultaneously. Place the potatoes in a large pot and cover with cold water by 1 inch.
Add 1 tablespoon of the 1.5 tsp Kosher Salt to the water and bring to a boil over high heat. Once boiling, reduce to a gentle simmer and cook for 15-18 minutes until the potatoes are fork-tender but not falling apart. Drain immediately and return to the pot to evaporate any remaining moisture.
Step 2: Infuse the Dairy with Garlic
While the potatoes cook, combine the 1 cup Heavy Cream, 0.5 cup Whole Milk, and 0.25 cup Heavy Whipping Cream in a small saucepan. Add the 3 cloves Garlic Cloves (minced or pressed) and warm over low heat for 3-4 minutes—just until small bubbles form at the edges.
This gentle heating infuses the cream mixture with garlic flavor without curdling. Remove from heat as soon as it’s warm; you want it hot enough to melt the butter but not boiling. The residual heat will continue the infusion process while you work with the potatoes.
Step 3: Rice the Potatoes for Ultra-Smooth Texture
Pass the drained potatoes through a ricer directly into the warm pot. If you don’t have a ricer, a food mill works well too. Avoid using a masher or mixer, as these can create gluey potatoes. The ricing process creates light, fluffy potatoes that will absorb the dairy beautifully.
Return the pot to low heat and stir the riced potatoes for 1-2 minutes to drive off any excess moisture. You’ll notice the potatoes become slightly drier and more receptive to the cream mixture. This step is crucial for achieving that restaurant-quality texture.
Step 4: Incorporate the Cream Mixture and Butter
Gradually pour the warm garlic-infused cream mixture into the potatoes while stirring constantly with a wooden spoon. Add the 1 cup Unsalted Butter (cut into small cubes) a few pieces at a time, allowing each addition to melt completely before adding more.
Stir in the 0.25 cup Sour Cream and remaining 0.5 tsp Kosher Salt. Continue stirring until the mixture is completely smooth and all the butter has melted. The potatoes should be glossy and hold soft peaks when the spoon is lifted. Taste and adjust seasoning with the 0.5 tsp Freshly Ground Black Pepper.
Step 5: Finish and Serve with Fresh Chives
Transfer the mashed potatoes to a serving bowl. The texture should be luxuriously creamy with a slight sheen from the butter. If they seem too thick, fold in a splash of warm milk. If too thin, return to low heat and stir for another minute to evaporate excess moisture.
Garnish with the 2 tbsp Chives (finely chopped) just before serving. The chives add a fresh, oniony brightness that cuts through the richness. Serve immediately while hot—they’ll thicken slightly as they cool, but the texture remains velvety smooth.
Pro Tips For Making Ruth Chris Mashed Potatoes
- Start in Cold Water: I learned this the hard way—always boil russets in cold, salted water starting from room temp. It guarantees even cooking so you don’t end up with a raw center and mushy edges.
- Warm Your Dairy: After burning a batch, I finally figured out that cold heavy cream and milk seize up in hot potatoes. Take 30 seconds to warm them in the microwave first.
- Rice the Potatoes: Sounds weird, but it works: use a ricer instead of a masher for that ultra-smooth Ruth’s Chris texture. A food mill works in a pinch—just skip the hand masher.
- Salt in Layers: More salt than you think, especially with unsalted butter. I do a pinch in the water, another when mashing, then taste and adjust—russets soak it up.
Perfect Pairings for This ruth chris mashed potatoes
Steakhouse Classics
These potatoes were born to pair with a perfectly cooked steak. I love them with a medium-rare ribeye or filet mignon—the rich beef juices soak into the creamy texture beautifully. The butter in the potatoes complements the steak’s natural fats without overpowering. 🔥
Seafood Companions
For a lighter meal, serve with pan-seared scallops or grilled salmon. The creamy potatoes balance the seafood’s delicate flavors, while the garlic note lifts the overall dish. I often add a squeeze of lemon to both components for brightness.
Poultry Partners
Roast chicken or turkey breast makes an excellent match. The potatoes soak up pan juices from the poultry, creating a luxurious sauce. I recommend a herb-roasted chicken with rosemary and thyme—those earthy notes pair wonderfully with the creamy texture.
Vegetable Sides
Add color and freshness with roasted asparagus or green beans. The crisp texture contrasts nicely with the smooth potatoes. For a heartier vegetarian option, serve with portobello mushrooms sautéed in butter and garlic.
Sauce Pairings
A rich red wine reduction or peppercorn sauce takes this to steakhouse levels. For a simpler approach, the pan juices from your main protein often provide enough flavor. I always keep some extra warm cream on hand to adjust consistency.
Beverage Matches
A bold Cabernet Sauvignon stands up to the richness, while a crisp Chardonnay offers a creamy complement. For non-alcoholic options, a sparkling water with lemon cleanses the palate between bites. 🍷

Frequently Asked Questions
Why use Russet potatoes instead of Yukon Golds?
Russets have a higher starch content, creating that signature fluffy texture. Yukon Golds work but lean waxier, resulting in a denser mash. For the creamiest results, Russets are non-negotiable.
Can I make these ahead of time?
Yes! Prepare everything except the butter and cream, then finish just before serving. Store cooked potatoes in an airtight container for up to 4 days. Reheat gently with a splash of milk to restore creaminess.
What if my potatoes turn out gluey?
This usually happens from overworking. Use a ricer or food mill, never a mixer. Also, ensure potatoes are fork-tender but not falling apart when boiled.
