Step‑by‑Step Instructions for Potatoes au Gratin

Step 1: Preheat and Prepare
Begin by preheating your oven to 425°F (220°C) to ensure it’s hot and ready for baking. While the oven heats up, grease an 8×8-inch baking dish with butter to prevent sticking, setting a cozy foundation for your Copycat Ruth’s Chris Potatoes au Gratin.

Step 2: Sauté the Aromatics
In a large skillet, melt 2 tablespoons of butter over medium heat. Add 1 finely chopped onion and sauté for about 5 minutes until it turns soft and translucent. This step cultivates a sweet aroma, enhancing the overall flavor profile of your potatoes au gratin.

Step 3: Add Garlic and Seasonings
Stir in 2 minced garlic cloves, along with salt and black pepper to taste. Cook for an additional 30 seconds until the garlic becomes fragrant, releasing its savory essence throughout your kitchen. This mixture will serve as a tasty base for the creamy sauce.

Step 4: Make the Creamy Sauce
Pour in 1 cup of chicken stock and 1 cup of heavy cream, stirring well to combine. Bring the mixture to a gentle simmer over medium heat, allowing the flavors to meld beautifully. Watch for small bubbles forming around the edges, signaling it’s ready for the potatoes.

Step 5: Coat the Potatoes
Thinly slice 4 russet potatoes to about 1/8 inch thick for even cooking. Add the slices to the skillet, ensuring each piece is coated in the creamy sauce. Carefully stir to combine, allowing the potatoes to absorb all that cheesy goodness as you prepare them for the oven.

Step 6: Simmer the Potatoes
Increase the heat slightly and cover the skillet, allowing it to simmer for 15-20 minutes. This step is crucial for ensuring your potatoes become tender, so check for a fork easily piercing through the potatoes – they should be nearly done before baking.

Step 7: Transfer to Baking Dish
Once the potatoes are tender, transfer the mixture into your prepared baking dish. Spread it out evenly, ensuring a nice layer is maintained. This ensures every bite of your Potatoes au Gratin will be perfectly creamy and delicious.

Step 8: Sprinkle with Cheese
Generously top the potato mixture with 1 ½ cups of shredded cheese, using a blend of cheddar, Fontina, and Parmesan for that delectable cheese pull. The cheese will create a golden, bubbly crust as it bakes, adding to the attractive presentation of your dish.

Step 9: Bake Until Golden
Place the baking dish in the oven and bake for 10-15 minutes, or until the cheese is melted and bubbly with a lovely golden brown crust on top. Keep an eye on it as it bakes; the enticing aroma will fill your kitchen with a comforting allure.

Step 10: Rest and Garnish
After removing the dish from the oven, allow it to rest for a few minutes. This brief waiting time helps the dish set properly, preventing it from being soupy. Before serving, sprinkle freshly chopped parsley on top for a pop of color and freshness to your warm, cheesy creation.

Expert Tips for Potatoes au Gratin

Slice Evenly: Ensure your potatoes are cut to about 1/8-inch thickness for uniform cooking, avoiding any undercooked or overcooked pieces.

Prep Ahead: If you’re short on time, assemble the dish (but don’t bake) and refrigerate it for up to 24 hours. Just remember to extend the baking time by 5-10 minutes.

Let It Rest: Allow your Potatoes au Gratin to sit for a few minutes after baking. This crucial step helps prevent a soupy texture when you serve it.

Cover While Cooking: Cover your skillet when simmering the potatoes. This action traps steam, helping them cook faster and tenderize beautifully.

Cheese Combos: Feel free to experiment with different cheese combinations. Mixing Gruyère with cheddar can elevate the flavor profile for an even cheesier dish.

How to Store and Freeze Potatoes au Gratin

Fridge: Store leftovers in an airtight container for up to 3 days. Reheat in the oven at 350°F until warmed through to maintain that delicious creamy consistency.

Copycat Ruth’s Chris Potatoes au Gratin Recipe FAQs

What type of potatoes should I use for Potatoes au Gratin?
Absolutely! I recommend using russet potatoes for this dish. They provide the perfect texture and structure, allowing them to layer beautifully and maintain their creaminess. Make sure to slice them about 1/8 inch thick for even cooking, as thicker slices may not tenderize properly during baking.

How should I store my leftovers?
You can store leftovers in an airtight container for up to 3 days in the refrigerator. It’s best to reheat them in the oven at 350°F (175°C) to ensure they regain their creamy, indulgent consistency. Just cover them with foil to avoid drying out!

Can I freeze Potatoes au Gratin?
Yes! You can freeze unbaked Potatoes au Gratin for up to 2 months. To do so, tightly wrap the dish in plastic wrap and then in aluminum foil. When you’re ready to enjoy, thaw it overnight in the refrigerator and add an extra 5-10 minutes to the baking time. This ensures they bake evenly and turn out perfectly!

How can I prevent my Potatoes au Gratin from becoming soupy?
Very! The key to achieving a non-soupy texture is to let the dish rest for a few minutes after baking. This resting period allows the cheese and cream to set up a bit, firming up the layers, so your serving scoops hold together nicely. Additionally, be careful not to overcook the potatoes during the simmering stage.

Are there any dietary considerations I should keep in mind?
Indeed! If you’re concerned about dietary restrictions, make sure to use vegetable broth instead of chicken stock for a vegetarian-friendly option. Additionally, be cautious with cheese selections if you or anyone eating has dairy allergies. You can also substitute with non-dairy cheese alternatives to cater to lactose-intolerant individuals.

Can I customize the cheese blend in this recipe?
The more the merrier! Feel free to mix and match different cheeses based on your preference. While the original calls for cheddar, Fontina, and Parmesan, you could easily swap in Gruyère for a nutty flavor or Monterey Jack for a milder taste. Just make sure whatever cheese you use melts well!
