Ingredients:
- 2 tbsp butter (plus extra for greasing the dish)
- 1/2 medium onion (minced)
- 1 clove garlic (minced)
- 1.25 tsp salt (for seasoning)
- 1/2 tsp ground black pepper (for seasoning)
- 3/4 cup chicken stock (for sauce)
- 1.25 cups heavy cream (for creamy texture)
- 1.5-1.75 lbs russet potatoes (about 5-6, peeled and sliced 1/8 inch thick)
- 3 cups shredded cheese (mix of 2 cups Cheddar, 3/4 cup Fontina or Provolone, and 1/4 cup Parmesan)
- 1 tbsp chopped parsley (for garnish)
Directions:
- Preheat your oven to 425°F (220°C) to ensure even baking.

Pro Tips for Success with Copycat Ruth’s Chris Potatoes au Gratin
- Choose the Right Potatoes: Stick to russet potatoes as they have the perfect starch content for this creamy dish. They hold their shape well and get deliciously tender.
- Slice Uniformly: Make sure to slice your potatoes evenly to ensure they cook at the same rate. A mandoline slicer can help you achieve this consistently.
- Keep an Eye on the Cheese: To avoid burning, check the cheese frequently towards the end of the baking time. If it gets too golden quickly, you can cover it with foil.
- Let It Rest: Allow the dish to rest for a few minutes after baking. This will help the sauce thicken up a bit, making it easier to serve.
- Experiment with Cheeses: Feel free to mix up the cheeses to match your palate! Fontina adds a nice creaminess, while Parmesan contributes a lovely sharpness.
Flavor Variations
- Add Some Spice: Infuse the dish with a pinch of red pepper flakes or a dash of hot sauce if you’re a fan of heat.
- Experiment with Herbs: Incorporate fresh herbs like thyme or rosemary for a flavor boost. You could also sprinkle some garlic powder or onion powder for added depth.
- Add Vegetables: Add steamed broccoli or sautéed spinach before topping with cheese for a healthier twist.
- Smoky Flavor: Consider using smoked cheese like Gouda for a unique, smoky flavor that pairs beautifully with the creamy sauce.
- Sweetness from Carrots: Thinly sliced carrots can add a hint of sweetness and color to the dish.
Serving Suggestions
Copycat Ruth’s Chris Potatoes au Gratin pairs wonderfully with a variety of main courses:
- Grilled Steak or Roast Beef: These hearty main dishes complement the creamy richness of the potatoes well.
- Baked Salmon or White Fish: The lightness of seafood balances the richness of the potatoes.
- Roasted Chicken: A classic combo, roasted or grilled chicken is always a winner alongside these cheesy potatoes.
- Vegetable Dishes: Consider serving your potatoes with a side of roasted vegetables or a fresh salad for a well-rounded meal.
Storage and Freezing Instructions
If you have leftovers, here’s how to store them properly:
- Refrigerating: Store any remaining potatoes au gratin in an airtight container in the refrigerator. It should be consumed within 3-4 days for optimal freshness and flavor.
- Freezing: For longer preservation, freeze portions in airtight containers or freezer bags. This dish can be frozen for up to 3 months. However, the texture may change slightly upon reheating.
- Reheating: To reheat, allow the frozen potatoes to thaw in the fridge overnight. Warm them in the oven at 350°F (175°C) until heated through, covering with foil to prevent over-browning.
