Homey, humble, yet so cheesy

Ruth’s Chris is well-known for its steaks, but that’s just one of their many strengths. Although their steak is amazing, I also love their side dishes and especially their potato gratin. It’s rich and creamy, and as cheesy and delicious as it gets. That’s why you should be able make it at your home and serve it to all your friends. It’s here in all its rich, cheesy glory. The good news is that it’s easy to make in your own kitchen.

Serves 4
10m prep time
25m cook time


2 tablespoons butter, plus more for greasing baking dish
1/2 white onion, minced
2 garlic cloves, minced
1 1/2 teaspoons salt
1/2 teaspoon freshly ground black pepper
1/2 cup chicken stock
1 1/4 cups heavy cream, plus more if needed
1 1/2 lbs russet potatoes, peeled and sliced 1/8-inch thick
2 cups cheddar cheese, grated
3/4 cup provolone cheese, grated
1/2 cup Parmesan cheese, grated
Fresh parsley, chopped, for garnish


Preheat oven to 425°F and grease an 8×8-inch baking dish with butter.

In a large pot over medium heat, melt the butter. Add onion and cook until soft and translucent, about 5 minutes. Add garlic and season with salt and pepper and cook 30 seconds more.

Stir in stock, cream, and potatoes and bring to a low simmer, but do not boil. Cover and reduce heat to medium-low. Let cook until potatoes are tender, 15-20 minutes. Adjust seasoning as needed.

Transfer mixture to baking dish, top with cheese and bake until bubbly and cheese has melted, 10-15 minutes.

Serve garnished with parsley, if desired. Enjoy!
