Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

  • 2 tablespoons butter (plus extra for greasing)
  • ½ medium onion, minced
  • 1 clove garlic, minced
  • 1¼ teaspoons salt
  • ½ teaspoon ground black pepper
  • ¾ cup chicken stock
  • 1¼ cups heavy cream
  • 1½ to 1¾ pounds russet potatoes, peeled and thinly sliced (approximately 5-6 potatoes)
  • 2 cups sharp cheddar cheese, shredded
  • ¾ cup Fontina or Provolone cheese, shredded
  • ¼ cup Parmesan cheese, grated
  • 1 tablespoon fresh parsley, chopped (for garnish)

Directions

  1. Preheat Oven: Preheat your oven to 425°F (220°C). Grease an 8×8-inch baking dish or individual ramekins with butter.
  2. Prepare the Cream Sauce: In a large skillet over medium heat, melt the butter. Add the minced onion and sauté until soft and translucent, about 5 minutes. Stir in the garlic, salt, and black pepper, cooking for 30 seconds until fragrant.
  3. Simmer the Potatoes: Pour in the chicken stock and heavy cream, stirring to combine. Add the peeled and thinly sliced potatoes, ensuring they are submerged in the liquid. Bring to a gentle simmer over medium heat, then reduce to medium-low. Cover and cook for 15-20 minutes, stirring occasionally, until the potatoes are nearly tender but still hold their shape.
  4. Assemble the Dish: Transfer the potato mixture to the prepared baking dish, spreading evenly. Combine the shredded cheddar, Fontina (or Provolone), and Parmesan cheeses in a bowl, then sprinkle evenly over the potatoes.
  5. Bake: Place the dish in the preheated oven and bake for 10-15 minutes, or until the cheese topping is melted, bubbly, and golden brown. Keep an eye on it to avoid over-browning.
  6. Garnish and Serve: Remove from the oven and let the dish rest for a few minutes to allow the sauce to set. Garnish with chopped parsley before serving.

FAQs

1. Can I make this dish ahead of time?

Yes, assemble the dish (without baking) and refrigerate for up to 24 hours. Bake just before serving.

2. Can I use Yukon Gold potatoes instead of russet?

Absolutely! Yukon Golds will provide a creamier texture and slightly buttery flavor.

3. How do I ensure the potatoes cook evenly?

Slice the potatoes thinly and evenly using a mandoline or sharp knife. This ensures consistent cooking.

4. Can I substitute the heavy cream?

Half-and-half can be used as a lighter alternative, though the dish will be less rich.

Potatoes au gratin pairs beautifully with steak, roasted chicken, pork chops, or grilled vegetables.

6. Can I freeze leftovers?

Yes, though the texture may change slightly. Wrap tightly and freeze for up to 1 month. Reheat in the oven for best results.

7. Can I use pre-shredded cheese?

Pre-shredded cheese is convenient but may not melt as smoothly due to added anti-caking agents. Freshly shredded is recommended.

8. How can I prevent the cheese topping from burning?

Check the dish frequently during baking and cover with foil if the cheese browns too quickly.

9. Can I make this without chicken stock?

Yes, substitute vegetable stock for a vegetarian option or use water with a pinch of extra seasoning.
