I don’t know about you, but eating at steakhouses isn’t my wheelhouse. So when I go, I read every inch of the menu and agonize over just the right choices to maximize my experience! (Then hate it if someone orders something that looks better than mine, lol!) And while I enjoy the steak, what makes it for me is the au gratin potatoes. My daughter takes after me; when she came back after a special dinner with her sweetie, what Jess raved about wasn’t the steak, it was Ruth’s Chris Potatoes au Gratin.
- 2 tablespoons butter plus additional to butter casserole dish
- 1/2 medium onion, minced
- 1 garlic clove, minced
- 1 1/4 teaspoon salt
- 1/2 teaspoon ground black pepper
- 3/4 cup chicken stock
- 1 1/4 cups heavy cream; add a little more if it doesn’t cover potatoes
- 1 1/2 to 1 3/4 pounds (about 5 to 6 medium) russet potatoes, peeled and sliced 1/8 inch thick (thickness of standard food processor slicing disc)
- 3 cups total finely shredded cheese: 2 cups Cheddar (8 ounces), and 3/4’s cup (3 ounces) of either Fontina or Provolone along with 1/4 cup (1 ounce) Parmesan, mixed together
- about 1 tablespoon chopped parsley for garnish
Preheat oven to 425 degrees F.
Melt the butter, and sauté the onion over medium heat until soft and translucent. Add the garlic, salt, and pepper and cook for about 30 seconds. Add the stock, cream, and potatoes and bring to a good (not a boil) simmer. Cover, reduce heat to medium-low and simmer gently until the potatoes are nearly tender when pierced with a knife, about 15 to 20 minutes. Taste and adjust seasoning to your taste. Gently stir.
Transfer the mixture to a buttered 8 x 8″ or equivalent sized baking dish (or about five to six individual casseroles). Top with the cheese and bake in the preheated oven for about 10 -15 minutes for the casserole (a little less for individual casseroles) or just until the sauce is bubbling and the cheese is melted. Cool a few minutes before serving. Sprinkle with chopped parsley.
Note: Although our family loves this just as is, this is a very creamy dish with cream, potatoes and cheese, and just a little onion, one clove garlic and the bit of chicken stock for additional flavor. It’s fine to taste the sauce before you transfer to the casserole and be sure to adequately season with salt and pepper. If you are a person who prefers a dish that is more highly flavored, feel free to increase the onion and/or garlic to taste.
