How to Make It

1. Preheat your oven to 375°F (190°C). Butter a 9×13 inch baking dish thoroughly.
2. In a large saucepan, combine the heavy cream, whole milk, minced garlic, salt, pepper, and nutmeg. Heat over medium-low heat, stirring occasionally, until the mixture is warm and the garlic is fragrant, but do not boil. Remove from heat.
3. Arrange half of the thinly sliced potatoes in an even layer in the prepared baking dish.
4. Sprinkle half of the Gruyère cheese and half of the sharp cheddar cheese over the potatoes.
5. Repeat with the remaining potatoes and cheeses, layering them over the first layer.
6. Carefully pour the warm cream mixture evenly over the potatoes and cheese, ensuring it seeps down into all the layers. Gently press down on the potatoes with a spatula to help them submerge and cook evenly. Make sure the liquid doesn’t quite reach the very top of the potatoes, allowing some to peek through for better browning.
7. Cover the baking dish tightly with aluminum foil.
8. Bake for 45 minutes.
9. Remove the foil and continue to bake for another 20-30 minutes, or until the potatoes are tender when pierced with a fork and the gratin is golden brown and bubbly on top. If the top starts to brown too quickly, you can loosely tent it with foil. The goal is a rich, creamy interior with a beautifully browned crust.
10. Let the potatoes au gratin rest for at least 10-15 minutes before serving. This allows the sauce to thicken and set, making it easier to serve and enhancing the overall texture.

Following these steps carefully will result in a truly satisfying Copycat Ruth’s Chris Potatoes au Gratin. The resting period is crucial for achieving the ideal consistency.

Common Mistakes

• Potatoes cut too thick or unevenly: This leads to uneven cooking, with some potatoes being mushy while others remain undercooked. Aim for consistent, thin slices (about 1/8 inch) for even texture. A mandoline slicer is helpful here, but a sharp knife and practice will suffice. It’s better to err on the side of slightly too thin than too thick.
• Not enough liquid: The potatoes need sufficient liquid to cook through and create that signature creamy sauce. Ensure the liquid level is nearly to the top of the potato layers before baking. If your dish is deeper than expected, you might need to slightly increase the cream and milk mixture.
• Over-salting: Cheese is naturally salty, especially Gruyère and cheddar. Start with the recommended amount of salt and adjust at the end if necessary. Tasting the cream mixture before pouring it over the potatoes can help prevent over-salting, though be mindful that raw garlic doesn’t taste the same as cooked.
• Skipping the resting time: While tempting to dig in immediately, allowing the gratin to rest is crucial. It allows the sauce to thicken and the layers to set, preventing a watery or soupy consistency when served. This short wait significantly improves the final texture.
• Using the wrong type of potato: Starchy potatoes like Russets can become too mushy and fall apart. Waxy potatoes like Yukon Golds hold their shape better while still absorbing the creamy sauce beautifully, providing a more desirable texture for gratin.
• Sauce not hot enough: While not strictly boiling, warming the cream and milk mixture helps to jumpstart the cooking process for the potatoes and allows the flavors to meld more effectively. Starting with a cold liquid would significantly increase the cooking time and might not yield the same creamy texture.
• Overcrowding the dish: If the dish is too full, the liquid may bubble over during baking, creating a mess and potentially leading to undercooked potatoes. Ensure there’s a little space at the top for the sauce to bubble without overflowing.
• Not covering during initial baking: Covering the gratin with foil for the first 45 minutes traps steam, ensuring the potatoes cook through evenly without the top browning too rapidly. Removing the foil allows for that desirable golden crust.
• Grating cheese too coarsely: Fine gratings of cheese melt more smoothly into the sauce and create a more cohesive final dish. While not a deal-breaker, it contributes to a better overall texture.
• Burning the garlic: Minced garlic can burn easily. Infuse it into the warm cream mixture gently over low heat to extract its flavor without bitterness; remove if it starts to brown significantly.

Avoiding these common pitfalls will help ensure your Copycat Ruth’s Chris Potatoes au Gratin turns out just as you imagined. Careful attention to detail makes all the difference in achieving that delightful restaurant-quality result.

Storage and Reheating

• Storage: Once cooled completely, cover the baking dish tightly with plastic wrap or transfer the gratin to an airtight container. It can be stored in the refrigerator for up to 3-4 days. Ensure it’s properly sealed to prevent it from drying out or absorbing other odors from the refrigerator.
• Reheating: The best way to reheat is in a moderate oven. Reheat individual portions in a small oven-safe dish or reheat the entire casserole in a 325°F (160°C) oven until heated through, which can take 20-30 minutes or more depending on the quantity. You can also cover it with foil to prevent the top from over-browning. For quicker reheating, a microwave can be used, but the texture may become slightly softer, and the crust won’t be as crisp. Some people prefer to briefly broil the gratin after reheating to restore some crispness to the top. If the gratin seems dry after reheating, you can add a splash of milk or cream before warming. Ensure the internal temperature reaches 165°F (74°C) for food safety.

Proper storage and reheating will help preserve the deliciousness of your Copycat Ruth’s Chris Potatoes au Gratin for days to come.

Leftover Ideas

• Breakfast Hash: Chop up leftover gratin and pan-fry it with some diced onions, peppers, and perhaps a fried egg on top for a hearty breakfast or brunch. The crispy bits from the gratin add a wonderful texture.
• Shepherd’s Pie Topping: Use a generous layer of cooled gratin as the topping for a savory meat pie. Spread it over your favorite shepherd’s pie filling and bake until golden and bubbly.
• Savory Pancakes/Fritters: Mix crumbled gratin with a little flour, egg, and perhaps some chopped herbs. Pan-fry spoonfuls to create delicious savory fritters or pancakes.
• Stuffed Mushrooms/Peppers: Gently warm the gratin and use it as a rich filling for large mushrooms or bell pepper halves. Bake until the mushrooms are tender or peppers are softened.
• Enrich Other Casseroles: Stir small amounts of leftover gratin into other casseroles, like a tuna noodle casserole or a chicken pot pie filling, to add an extra layer of creaminess and flavor.
• Standalone Deliciousness: Let’s be honest, sometimes the best way to enjoy leftovers is to simply reheat them and savor them as they are. Cold gratin can also be surprisingly enjoyable for some.

These ideas offer creative ways to give your Copycat Ruth’s Chris Potatoes au Gratin a second life, ensuring no delicious morsel goes to waste.
