Ruth’s Chris Potatoes au Gratin Copycat Recipe – Restaurant Style at Home

I’ve been making this restaurant-style potato dish for years after falling in love with Ruth’s Chris steakhouse version. The combination of tender Yukon potatoes layered with rich cream and sharp cheese creates that indulgent side dish we all crave. This copycat recipe brings that steakhouse experience right to your home kitchen.

Why This Ruth’s Chris Potatoes au Gratin Works

The secret lies in the careful balance of cream, cheese, and perfectly sliced potatoes. Using heavy cream instead of milk creates that luxurious texture, while the combination of sharp cheddar and Gruyère cheese adds depth. The slow baking process allows the flavors to meld beautifully while creating those golden, bubbly edges.

Ingredients

• 3 pounds Yukon Gold potatoes, peeled and sliced 1/8-inch thick
• 2 cups heavy whipping cream
• 1 cup whole milk
• 4 cloves garlic, minced
• 2 teaspoons kosher salt
• 1 teaspoon black pepper
• 1/2 teaspoon ground nutmeg
• 2 tablespoons fresh thyme leaves
• 1 1/2 cups sharp cheddar cheese, grated
• 1 cup Gruyère cheese, grated
• 3 tablespoons butter, cut into small pieces
• 2 tablespoons chives, finely chopped (for garnish)

These ingredients work together to create layers of flavor that mirror the restaurant’s famous dish. The key is using quality cheese and fresh herbs to elevate the overall taste profile.

How to Make It

1. Preheat your oven to 375°F and generously butter a 9×13-inch baking dish. This prevents sticking and adds extra richness to the bottom layer of potatoes.
2. Wash and peel the Yukon Gold potatoes thoroughly. Using a sharp knife or mandoline slicer, cut the potatoes into uniform 1/8-inch thick slices. Consistent thickness ensures even cooking throughout the dish.
3. In a large saucepan over medium heat, combine the heavy cream, whole milk, minced garlic, kosher salt, black pepper, and nutmeg. Heat the mixture until it just begins to simmer, stirring occasionally to prevent scorching. Remove from heat and stir in the fresh thyme leaves.
4. Layer half of the sliced potatoes in the prepared baking dish, overlapping slightly in an organized pattern. This creates the foundation for your gratin and ensures even distribution of the cream mixture.
5. Pour half of the warm cream mixture over the first layer of potatoes, making sure it reaches all corners of the dish. Sprinkle half of the cheddar cheese and half of the Gruyère cheese evenly over the cream-soaked potatoes.
6. Repeat the layering process with the remaining potatoes, creating another overlapping layer. Pour the remaining cream mixture over the top, ensuring all potato slices are covered. The liquid should come nearly to the top of the potatoes.
7. Cover tightly with aluminum foil and bake for 45 minutes. This initial covered baking allows the potatoes to steam and become tender while absorbing the creamy sauce.
8. Remove the foil and sprinkle the remaining cheddar and Gruyère cheeses over the top. Dot the surface with small pieces of butter, which will help create a golden, crispy top layer.
9. Return to the oven uncovered and bake for an additional 25-30 minutes, or until the top is golden brown and bubbly. The edges should be crispy while the center remains creamy.
10. Remove from the oven and let rest for 10-15 minutes before serving. This resting time allows the cream to thicken slightly and makes serving much easier. Garnish with fresh chopped chives for color and mild onion flavor.

The result is a rich, creamy potato dish with layers of flavor that rivals any steakhouse version. The resting period is crucial for achieving the right consistency when serving.

How to Serve It

• Pair with grilled or roasted meats like steak, lamb, or pork tenderloin
• Serve alongside roasted chicken or turkey for Sunday dinner
• Include as part of a holiday meal with ham or prime rib
• Offer as a vegetarian main course with a fresh green salad
• Present in individual ramekins for elegant dinner parties
• Accompany with steamed vegetables to balance the richness
• Serve with crusty bread to soak up any extra cream sauce

This versatile side dish complements both casual family dinners and special occasion meals. The rich, creamy texture makes it an excellent companion to simply prepared proteins that might otherwise seem plain.

Common Mistakes

• Slicing potatoes too thick, which prevents proper cooking and cream absorption
• Not seasoning the cream mixture adequately, resulting in bland potatoes
• Using low-fat dairy products, which won’t create the proper creamy texture
• Overcooking the initial cream heating, causing it to curdle or separate
• Skipping the resting period, making the dish difficult to serve neatly
• Not covering during the first baking phase, leading to dry, tough potatoes
• Using pre-shredded cheese, which contains anti-caking agents that affect melting
• Not buttering the baking dish properly, causing sticking and difficult cleanup
• Baking at too high temperature, which browns the top before the potatoes cook through

Avoiding these common pitfalls will help you achieve the creamy, restaurant-quality results you’re looking for. Taking time with each step ensures the best possible outcome.

Storage and Reheating

• Refrigerate leftovers within 2 hours of cooking in covered containers
• Store in the refrigerator for up to 4 days maximum
• Reheat individual portions in the microwave on 50% power to prevent overheating
• Warm larger portions in a 350°F oven covered with foil for 20-25 minutes
• Add a splash of cream or milk when reheating to restore creaminess
• Freeze portions for up to 2 months in freezer-safe containers
• Thaw frozen portions overnight in the refrigerator before reheating
• Cover with fresh cheese before reheating for renewed flavor
• Avoid reheating multiple times to maintain food safety

Proper storage and gentle reheating help maintain the dish’s creamy texture and prevent the dairy from separating. Adding a bit of fresh cream during reheating can help restore the original consistency.

Leftover Ideas

• Transform into breakfast hash by adding diced ham and topped with fried eggs
• Use as a base for shepherd’s pie with ground meat and vegetables on top
• Incorporate into breakfast casseroles with eggs and breakfast sausage
• Create potato cakes by forming into patties and pan-frying until crispy
• Add to soup as a creamy, hearty base with additional broth and vegetables
• Stuff into baked chicken breasts for an elevated dinner presentation
• Layer in a breakfast burrito with scrambled eggs and bacon
• Mix with cooked vegetables for a complete one-dish meal
• Use as a filling for savory crepes or omelets
• Combine with cooked pasta for an indulgent mac and cheese variation

These creative uses for leftovers help you avoid food waste while creating entirely new meals. The rich, creamy base works well in many different applications beyond the original dish.
