Step‑by‑Step Instructions for Copycat Ruth’s Chris Potatoes au Gratin
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). This step is crucial for achieving that perfect golden brown top on your Copycat Ruth’s Chris Potatoes au Gratin. Ensure your oven is fully heated before moving on to the next steps, as a hot oven will help your dish bake evenly and bubble beautifully.
Step 2: Sauté the Aromatics
In a skillet, melt a generous amount of butter over medium heat. Once melted, add finely chopped onion and sauté until soft and translucent, about 5 minutes. Just before the onions are done, toss in minced garlic, salt, and ground black pepper, cooking for an additional 30 seconds to release those delightful aromas that will awaken your taste buds.
Step 3: Create the Creamy Base
Pour in rich chicken stock and heavy cream into the skillet, stirring well to combine all the ingredients into a smooth, savory sauce. Let this mixture come to a gentle simmer; watch for bubbling as it thickens slightly. This creamy base will coat the potatoes wonderfully, enhancing the flavors of your Copycat Ruth’s Chris Potatoes au Gratin.
Step 4: Prepare the Potatoes
Add the thinly sliced Russet potatoes into the creamy mixture, ensuring each slice is well coated. Then, cover the skillet and let it simmer on medium-low heat for 15-20 minutes. Stir occasionally until the potatoes are nearly tender; they should be soft but still hold their shape as they will finish cooking in the oven.
Step 5: Assemble the Dish
Grease an 8×8-inch baking dish or individual ramekins with butter to prevent sticking. Carefully transfer the potato mixture into the prepared dish, spreading it evenly to ensure every bite is rich in flavor. This layer of creamy potatoes is the heart of the Copycat Ruth’s Chris Potatoes au Gratin, so make sure it’s nicely arranged.
Step 6: Add the Cheese Topping
Generously sprinkle a layer of shredded cheese on top of the potato mixture. This will create that deliciously bubbly and golden crust we all love. Place the dish in the preheated oven and bake for about 10-15 minutes or until the cheese is melted, golden, and bubbling—this is when the magic truly happens!
Step 7: Garnish and Serve
After baking, let the dish cool for a few minutes to set. Just before serving, garnish with freshly chopped parsley for a pop of color and freshness. Serve warm alongside your favorite main dishes, and watch as everyone enjoys your homemade Copycat Ruth’s Chris Potatoes au Gratin with delight!

Expert Tips for Copycat Ruth’s Chris Potatoes au Gratin

Copycat Ruth’s Chris Potatoes au Gratin Recipe FAQs
How do I choose the best potatoes for this dish?
Absolutely! For the best results, I recommend using Russet potatoes due to their starchy texture, which allows them to hold up well during baking. Look for potatoes that are firm and have minimal blemishes. Avoid any with dark spots or sprouts for the freshest taste. Yukon Gold potatoes can also be a yummy alternative, bringing a slightly buttery flavor to your gratin.
How should I store leftover potatoes au gratin?
Store any leftovers in an airtight container in your refrigerator for up to 3 days. Allowing the dish to sit lets the flavors meld, making each bite just as comforting as the first! When ready to enjoy again, simply reheat in the oven for that freshly-baked taste.
Can I freeze Copycat Ruth’s Chris Potatoes au Gratin?
Yes, you can! To freeze, portion the cooled gratin into individual servings and wrap them tightly in plastic wrap before placing them in a freezer-safe bag or container. This way, the dish will remain fresh for up to 2 months. To reheat, thaw in the fridge overnight, then warm it up in the oven at 350°F (175°C) until heated through.
What if my cheese doesn’t melt properly?
If your cheese doesn’t melt or brown as desired, check the quality of your cheese. Using freshly shredded cheese often yields better results than pre-shredded blends, which contain anti-caking agents. Additionally, if the cheese is browning too slowly and the potatoes are done, crank up the oven to broil (monitor closely!) for just a couple of minutes until that golden brown topping forms.
Are these potatoes suitable for dietary restrictions?
Absolutely! You can easily make this dish vegetarian by substituting the chicken stock with vegetable stock. If you have a dairy allergy, consider using non-dairy cream or a cheese alternative. Just ensure to read the labels to find suitable substitutes that fit your specific dietary needs.
Can I make this dish ahead of time?
Yes, indeed! If you need to prepare it ahead, simply assemble the dish without baking, cover it, and store it in the fridge for up to 24 hours. When you’re ready to serve, bake it straight from the fridge—just add an additional 5-10 minutes to the baking time for that perfectly bubbling, cheesy delight.
