Introduction to Potatoes au Gratin

Potatoes au Gratin is a classic French-style casserole of thinly sliced potatoes baked in cream and cheese until soft and golden. This Ruth’s Chris-inspired version adds depth by using a mix of cheddar, provolone, and Parmesan and by simmering the potatoes gently in a seasoned cream and stock mixture before baking. The result is ultra-creamy layers with a crisp, savory topping—comfort food that elevates any meal.

Ingredients for Ruth’s Chris-Inspired Potatoes au Gratin

Gather the following ingredients:

• 2 tablespoons butter, plus extra for greasing
• 1/2 medium onion, finely chopped
• 1 clove garlic, minced
• 1 1/4 teaspoons salt
• 1/2 teaspoon ground black pepper
• 3/4 cup chicken stock (use vegetable stock to make it vegetarian)
• 1 1/4 cups heavy cream (or half-and-half for a lighter version)
• 1 1/2 to 1 3/4 pounds russet potatoes, peeled and sliced 1/8 inch thick
• 3 cups mixed shredded cheese: 2 cups cheddar (about 8 oz), 3/4 cup provolone (about 3 oz), and 1/4 cup Parmesan (about 1 oz)
• 1 tablespoon chopped parsley, for garnish

How to Make Potatoes au Gratin – Step by Step

Follow these clear steps for a reliable, restaurant-style potatoes au gratin.

Step 1: Prep and Sauté the Aromatics

In a skillet over medium heat, melt 2 tablespoons of butter. Add the finely chopped onion and sauté for about 4–5 minutes, until softened and translucent. Stir in the minced garlic, salt, and pepper and cook another 30 seconds until fragrant. This builds a savory base for the cream sauce.

Step 2: Create the Creamy Sauce

Add 3/4 cup of chicken stock and 1 1/4 cups of heavy cream to the skillet. Stir and bring the mixture to a gentle simmer. Add the sliced potatoes and toss to coat them evenly. Reduce heat to medium–low, cover, and simmer for 15–20 minutes, or until the potatoes are tender but still hold their shape. This step infuses the potatoes with flavor and shortens the final bake time.

Step 3: Assemble and Bake

Preheat your oven to 425°F (220°C). Butter an 8 x 8-inch casserole dish and transfer the potato mixture into it, arranging the slices in even layers if needed. Sprinkle the shredded cheese evenly on top—start with cheddar, follow with provolone, and finish with Parmesan. Bake for 10–15 minutes until the cheese is melted and bubbling and the top is golden. For an extra-crisp finish, broil for 2–3 minutes while watching closely. Garnish with chopped parsley and let rest a few minutes before serving.

Helpful Tips for Potatoes au Gratin

• Choose the right potato: Russets give a fluffy interior; Yukon Golds offer a creamier texture—both work well depending on your preference.
• Slice evenly: Use a mandoline or a sharp knife to cut uniform 1/8-inch slices so all pieces cook at the same rate.
• Cheese choices: The recommended blend gives flavor and meltability. You can substitute gruyère, Gouda, or mozzarella to vary taste and texture.
• Simmer gently: Keep the sauce at a low simmer so the cream doesn’t curdle and the potatoes absorb flavor.

Cooking Tips for the Best Potatoes au Gratin

• For even cooking, arrange potato slices in a single overlapping layer before covering with sauce and cheese.
• If you prefer a thinner sauce, add a little more cream or stock; for richer results, increase the cream slightly.

Serving Suggestions

This potatoes au gratin pairs beautifully with hearty mains and simple sides:

• Grilled steak—the creamy potato balances bold, charred flavors.
• Roast chicken—a classic combination for family dinners.

Reheating: Reheat individual portions in the microwave for 1–2 minutes, or warm the casserole in a 350°F (180°C) oven for 15–20 minutes until heated through. If the top loses crispness, broil briefly to refresh the crust.

Frequently Asked Questions (FAQs)

1. Can I make Potatoes au Gratin ahead of time?
Yes. Assemble the recipe up to the baking step, cover, and refrigerate. Bake just before serving for best results.

2. What potatoes work best?
Russets are a classic choice for their fluffy interior; Yukon Golds yield a creamier texture. Avoid waxy potatoes that won’t soften as well.

3. How to make this vegetarian?
Replace the chicken stock with vegetable stock to keep the flavor while making the dish vegetarian.

4. Can I freeze Potatoes au Gratin?
