These ingredients are straightforward and accessible, yet each plays a crucial role in creating the luscious texture and depth of flavor that make the dish unforgettable. From the earthy potatoes to the sharp cheeses and rich cream, every item contributes to this cheesy masterpiece.

Russet potatoes (5 large, peeled and thinly sliced): Their starchy texture is perfect for creamy, tender layers that soak up all the flavors.
Medium onion (1, thinly sliced): Adds a gentle sweetness and aromatic depth to balance the richness.
Heavy cream (1 cup): Provides the silky, decadent sauce that coats every slice perfectly.
Cheddar cheese (1 cup, shredded): Brings a sharp, tangy bite that melts beautifully.
Parmesan cheese (½ cup, grated): Offers a nutty, savory finish that crisps up on top.
Garlic (2 cloves, minced): Infuses the dish with aromatic warmth without overpowering.
Butter (2 tablespoons, softened): Used to grease the crockpot, ensuring the potatoes don’t stick and adding richness.
Salt (1 teaspoon, to taste): Essential for unlocking all the flavors layered within.
Black pepper (½ teaspoon, to taste): Adds just the right hint of spice to balance the creaminess.

How to Make Easy Copycat Ruth’s Chris Potatoes au Gratin Recipe

Step 1: Prepare the Crockpot

Start by greasing the inside of your crockpot with the softened butter or a good nonstick spray. This simple step helps prevent sticking and adds that smooth buttery finish that makes each bite melt-in-your-mouth delightful.

Step 2: Layer the Potatoes and Onions

Arrange a neat layer of the thinly sliced russet potatoes across the bottom of the crockpot. Follow with a thin layer of the sliced onions on top to introduce a subtle sweetness. Season this layer lightly with salt and black pepper to draw out the best flavors from each ingredient.

Step 3: Pour the Cream and Garlic Mixture

In a small bowl, mix the heavy cream with the minced garlic to create a garlicky sauce that will soak into each potato slice during the slow cooking process. Pour this evenly over your layered potatoes and onions, making sure every bite will be rich and flavorful.

Step 4: Add the Cheese Layers

Sprinkle the cheddar cheese and Parmesan over the cream-soaked potatoes. The cheddar melts into a dreamy gooey texture while the Parmesan contributes a crispy, golden top. Repeat these layers until you’ve used all your ingredients, ensuring the final layer is cheese for a beautifully browned finish.

Step 5: Cook Low and Slow

Cover the crockpot with its lid and set it on low for about 4 to 5 hours. This long, slow cook time lets the potatoes soften perfectly, allowing every slice to absorb the savory cream and cheese sauce. If you are in a hurry, setting the crockpot to high for 2 to 3 hours will also work, but low and slow leads to the best texture.

Step 6: Finish with a Broil

Once cooked through and tender, transfer the crockpot contents to an oven-safe dish and place it under the broiler for 2 to 3 minutes. This final step crisps the cheesy top layer into that signature golden crust you expect from Ruth’s Chris, while letting the dish rest for 5 to 10 minutes intensifies the flavors before serving.

Garnishes

For a beautiful presentation, sprinkle freshly chopped parsley or chives on top before serving. These green herbs add a pop of color and a fresh bite that contrasts perfectly with the creamy richness of the potatoes au gratin.

Side Dishes

This dish pairs wonderfully with a juicy steak, roasted chicken, or even simple steamed veggies for a balanced but indulgent meal. The creamy potatoes make an ideal companion to protein-focused mains, especially during holiday celebrations or special dinners.

Creative Ways to Present

For a twist, serve the potatoes au gratin in individual ramekins or small cast iron skillets for personal servings. Another fun idea is to layer it with caramelized onions or sautéed mushrooms to add texture and flavor complexity that will wow your guests.

Make Ahead and Storage

Storing Leftovers

Keep any leftovers covered tightly in an airtight container and store them in the refrigerator for up to 3 days. The flavors develop even more after a day, making it a perfect make-ahead side for busy evenings.

Freezing

You can freeze portions in airtight containers or freezer bags for up to 2 months. Just be sure to thaw overnight in the fridge before reheating to maintain the best texture and taste.

Reheating

Reheat leftovers gently in the oven at 350°F for about 20 minutes until warmed through, or microwave individual portions with a cover to keep moisture in. Avoid overheating to keep the potatoes tender and creamy instead of dry.

FAQs

Can I use other types of potatoes for this recipe?

While russet potatoes are ideal due to their texture and starch content, you can experiment with Yukon Gold potatoes for a slightly creamier, buttery bite. Just note that texture and cook time might slightly vary.

Is there a way to make this recipe vegetarian friendly?

This dish is naturally vegetarian since it relies on dairy for richness. Just be sure to use vegetarian-friendly cheese that does not contain animal rennet if that is a concern.

Can I prepare this dish without a crockpot?

Absolutely! You can layer the ingredients in a baking dish and bake at 350°F for about 1 to 1.5 hours until the potatoes are tender and cheese is bubbly and golden on top.

What can I use instead of heavy cream?

For a lighter version, you might substitute half-and-half or whole milk combined with a bit of flour or cornstarch to help thicken. Keep in mind that the texture won’t be quite as rich and creamy as with heavy cream.

How do I achieve the perfect golden crust on top?

The key is broiling the potatoes for a brief 2 to 3 minutes at the end. Keep a close eye to prevent burning, and this step will give you that signature golden, crispy top that makes this dish so irresistible.
