Ingredients
  

For the Potato Mixture
  • 2 tbsp butter (plus extra for greasing the dish)
  • 1/2 medium onion, minced
  • 1 clove garlic, minced
  • 1.25 tsp salt
  • 1/2 tsp ground black pepper
  • 3/4 cup chicken stock
  • 1.25 cups heavy cream
  • 1.5-1.75 lbs russet potatoes (about 5-6, peeled and sliced 1/8 inch thick)
For the Cheese Topping
  • 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)

Method
 

Preparation
  1. Preheat your oven to 425°F (220°C).
  2. In a large skillet over medium heat, melt 2 tablespoons of butter.
  3. Add minced onion and cook for about 5 minutes until soft, then add garlic, salt, and pepper. Cook for an additional 30 seconds until fragrant.
  4. Pour in the chicken stock and heavy cream, stirring to combine.
  5. Add the thinly sliced potatoes, ensuring they are well-coated in the sauce.
  6. Increase the heat to bring the mixture to a simmer. Cover, reduce heat to medium-low, and cook until the potatoes are nearly tender, about 15-20 minutes. Stir occasionally.
Baking
  1. Butter an 8×8-inch baking dish or five to six small individual dishes.
  2. Transfer the potatoes and sauce to the prepared baking dish, spreading evenly.
  3. Top with an even layer of the shredded cheese mixture.
  4. Bake for 10-15 minutes, or until the cheese is melted and golden brown.
  5. Let the dish rest for a few minutes before serving.
  6. Sprinkle with chopped parsley and serve warm.

Notes

Store leftovers in an airtight container in the fridge for up to 3-4 days. Reheat in the oven or microwave. Experiment with cheese varieties like Gruyère or add cooked bacon bits for extra flavor.
