The potatoes are non-negotiable—Russet gives you the starchy texture you need. Whole Foods or Trader Joe's usually have the best selection, but any grocery store carries them. Look for firm, blemish-free tubers—they slice cleaner. I always peel mine (the skin can get rubbery after baking), but if you prefer rustic texture, leave it on. The cheese? Sharp white cheddar is key—it melts beautifully without overpowering. Kraft isn't cutting it here—grate your own from a block for that perfect texture. For the wine, any dry white works—Sauvignon Blanc or Chardonnay from the store's mid-range section is perfect.
No white wine? Chicken or vegetable broth with a splash of lemon juice works in a pinch. Pre-shredded cheese? Toss it in a food processor with a little flour to break up the clumps. Running short on butter? Ghee or extra olive oil keeps the same richness. The nutmeg is crucial—pre-ground loses potency fast, so buy whole and grate fresh. For extra crispiness, mix 1 tbsp flour into the breadcrumbs before topping. And if you're feeling fancy, add 1/4 cup Gruyère to the cheese mix for a restaurant-style touch.
This reheats beautifully—just cover with foil and warm at 350°F for 15 minutes. Leftovers keep for 4-5 days in the fridge, though I rarely have any. For make-ahead prep, assemble the dish (without baking) and refrigerate overnight—bake straight from cold. The breadcrumb topping stays crispy for 2 days if stored airtight. For parties, double the recipe—it disappears fast.

Step-by-step instructions for ruth's chris steakhouse potatoes au gratin
Here's how to recreate that legendary restaurant texture at home—creamy layers with a golden, crispy top.
Prep the Potatoes for Perfect Layers
Peel the 2.5 lb russet potatoes and slice them into ⅛-inch thick rounds using a mandoline or sharp knife. You want even slices that'll cook uniformly. Soak the sliced potatoes in cold water for 10 minutes to remove excess starch—this keeps them from turning gummy later. Drain and pat them completely dry with paper towels.
Here's the thing—wet potatoes steam instead of crisping. I like to arrange the slices in a single layer on a baking sheet while drying to prevent overlapping. Once they're bone-dry, you're ready for the next step. This prep work makes all the difference in achieving that signature pull-apart texture.
Build the Creamy Cheese Sauce Base
In a large saucepan, melt the 4 tbsp unsalted butter over medium heat. Once foaming subsides, whisk in the 0.25 cup all-purpose flour and cook for 1-2 minutes until it forms a pale roux. This is your sauce foundation—don't let it brown or it'll taste bitter.
Gradually whisk in the 0.5 cup dry white wine, scraping up any browned bits from the bottom. Let it simmer for 2 minutes until mostly evaporated. Then add the 1.5 cups heavy cream, 0.5 cup whole milk, 1 tsp diamond crystal kosher salt, 0.5 tsp freshly ground black pepper, and 0.25 tsp fresh nutmeg. Stir constantly until the sauce thickens enough to coat the back of a spoon—about 5-6 minutes on medium-low heat.
Layer Potatoes and Cheese for Maximum Gooeyness
Preheat your oven to 375°F. Grease a 9x13-inch baking dish with 2 tbsp extra-virgin olive oil—this prevents sticking and helps crisp the edges. Start by layering half the potato slices in the dish, slightly overlapping them. Sprinkle with half the 1.5 cups shredded sharp white cheddar cheese and about ⅓ of the sauce. Repeat with remaining potatoes, cheese, and sauce.
The key here is even distribution—don't skimp on the cheese between layers. Press down gently on each layer to help the potatoes cook through evenly. The top layer should end with cheese and sauce, not potatoes. This ensures that crispy crust we're all craving.
Bake Until Golden and Bubbly
Cover the baking dish tightly with aluminum foil and bake for 45 minutes. This steaming phase ensures the potatoes cook through without drying out. After 45 minutes, remove the foil and sprinkle the 0.25 cup panko breadcrumbs evenly over the top. Return to the oven uncovered for 15-20 minutes until the top is deep golden brown and bubbly.
Watch closely during the final minutes—you want that crust to be crispy but not burnt. The edges should pull away from the dish slightly, and the cheese should be melted but not runny. If it's browning too quickly, tent loosely with foil to prevent burning while still allowing the top to crisp.
Rest and Serve with Restaurant-Quality Flair
Let the potatoes au gratin rest for 10 minutes before serving. This crucial step allows the layers to set slightly and makes slicing cleaner. The internal temperature should reach 180°F—probe the center to confirm. When ready, run a thin knife around the edges to loosen, then slide a spatula underneath to lift the entire casserole onto your serving platter.
For that final restaurant touch, garnish with extra black pepper and a sprinkle of fresh nutmeg. Serve immediately with a steak or chicken—each bite should deliver that perfect combination of creamy, cheesy layers with a crispy, golden top that's impossible to resist. The cheese should pull slightly when you cut into it, revealing those beautiful, gooey layers underneath.
Pro Tips For Making Ruth'S Chris Steakhouse Potatoes Au Gratin
- Prep Potatoes Uniformly: Slice them exactly ¼-inch thick—no thicker, no thinner. I learned this after one batch turned out mushy in the middle while another stayed raw. Use a mandoline if you’re impatient like me, but keep your hands steady if you’re doing it by hand.
- Shred Cheese Fresh: Buy the sharp white cheddar in a block and shred it yourself—right before layering. Pre-shredded cheese has anti-caking agents that make the gratin gummy. If you’re in a rush, pulse it in the food processor but don’t overdo it; you want visible texture.
- Bake Low and Slow: Start at 375°F, but after the first 20 minutes, drop it to 325°F. The high heat gets the top golden, but the low finish guarantees the center melts into creamy perfection. I used to rush it, and the cheese always ended up oily or undercooked.
- Whisk the Cream Cold: Chill the heavy cream and milk before mixing with butter—yes, even if the recipe doesn’t say it. Warm dairy separates, and you’ll end up with a greasy mess instead of a velvety sauce. Stir in the butter last, off the heat, until it’s silky. Trust me, it’s worth the extra minute.
Make-ahead tips for leftovers
Assemble Ahead
Prepare the entire dish up to the baking step 24 hours in advance. Layer the potatoes, cheese, and sauce in a 9x13-inch baking dish, cover tightly with plastic wrap, and refrigerate.
This allows flavors to meld beautifully and makes baking day stress-free. When ready to bake, simply remove from the fridge and follow the baking instructions—no need to thaw or adjust times. 📅
Breadcrumbs Trick
For an extra-crispy top, mix 1/4 cup panko breadcrumbs with 1 tbsp all-purpose flour before sprinkling on top. The flour helps create a sturdier crust that browns evenly. I like to press the breadcrumb mixture gently into the sauce before baking to ensure maximum crispiness.
This works especially well if you're prepping ahead—just add the breadcrumbs right before the final baking phase. ✨
Freezer-Friendly Prep
Assemble the dish completely (including cheese sauce) and freeze in a single layer for up to 1 month. When ready to bake, thaw overnight in the fridge, then bake as directed.
For best results, add the breadcrumbs fresh from the freezer—skip the foil cover during the final 20 minutes of baking to crisp the top properly. The texture remains creamy inside with a satisfying crunch. ❄️
Portion Control
Divide the assembled (unbaked) dish into individual 8x8-inch baking dishes for easy reheating. Cover each with foil and freeze for 1-2 months. When needed, bake from frozen at 375°F for 50 minutes, uncovered for the last 15 minutes.
This makes it perfect for meal prep—just grab and bake individual portions without thawing. 🔥
Reheating Leftovers
Cover leftover potatoes au gratin with foil and warm in a 350°F oven for 15 minutes. For microwave reheating, cover with a damp paper towel and heat on 50% power for 2-3 minutes**, stirring halfway.
Add a splash of milk or cream if the cheese looks dry. The breadcrumb topping stays crispy best when reheated gently—avoid high heat that can make it soggy. 💫
Party-Size Prep
Double the recipe and assemble in a 10x15-inch baking dish for crowd feeding. Bake at 375°F for 50 minutes covered, then 20 minutes uncovered. Use two 9x13-inch dishes side-by-side for even baking.
For easy serving, cut into squares with a hot knife—this keeps the edges crispy. Prep this ahead and keep warm in a 200°F oven until serving. 🍽️

Frequently asked questions
Can I use sweet potatoes instead of russet potatoes?
While you can use sweet potatoes, the texture and flavor will differ significantly. Russets provide the starchy, fluffy base that creates that signature pull-apart quality. Sweet potatoes would make the dish sweeter and denser. If you're set on using them, reduce the sugar in the cheese sauce slightly (by about 1 tsp) to balance the flavor.
Why did my top turn out soggy instead of crispy?
Soggy tops usually happen from one of three issues: insufficient baking time, missing the breadcrumb step, or covering too long. First, ensure you remove the foil for the final 15-20 minutes of baking. Second, always use panko breadcrumbs (not regular) and press them gently into the sauce before baking. Finally, check your oven temperature—375°F is critical for proper browning.
Can I make this dish in a smaller baking dish?
Yes, but the baking time may need adjustment. For an 8x8-inch dish, reduce the recipe by half and bake covered for 35 minutes, then uncovered for 10-15 minutes. The key is maintaining the same layering technique—thin potato slices with generous cheese between layers. A smaller dish will require more frequent checking to prevent over-browning.
What cheese can I substitute if I don't have sharp white cheddar?
For best results, use a blend of Gruyère and fontina (50/50 ratio) for that signature restaurant melt. If you only have mild cheddar, add ½ tsp extra mustard powder to the sauce to compensate for the lack of sharpness. Avoid pre-shredded cheese—it contains anti-caking agents that prevent proper melting. Freshly grated is always the way to go.
How do I keep the potatoes from getting watery?
Watery potatoes are almost always caused by not drying them thoroughly after soaking. After slicing, pat each layer with paper towels until completely dry. Also, ensure your baking dish is well-greased (use olive oil, not butter) and that you're not overfilling it. The dish should be no more than ¾ full to allow proper steam escape during baking.
