Ingredients
  

For the Cream Sauce
  • 3 tablespoons Butter Greasing the dish; substitute with olive oil for lighter option.
  • 1 medium Onion Finely minced; shallots can be used for milder flavor.
  • 2 cloves Garlic Minced; fresh cloves preferred.
  • 1 teaspoon Salt Adjust based on dietary preferences.
  • 1 teaspoon Ground Black Pepper Mild heat; white pepper is a subtler alternative.
For the Potatoes
  • 4 cups Russet Potatoes Sliced thinly (1/8 inch) for optimal creaminess.
  • 1 cup Chicken Stock Vegetable stock works for a vegetarian version.
  • 1 cup Heavy Cream Half-and-half can be a lower-fat substitute.
For the Cheese Topping
  • 2 cups Shredded Cheese Mix Blend of Cheddar, Fontina, and Parmesan.
  • 2 tablespoons Chopped Parsley Fresh garnish; optional.

Equipment

  • large skillet
  • Baking dish

Method
 

Step-by-Step Instructions
  1. Preheat your oven to 425°F (220°C).
  2. In a large skillet over medium heat, melt about 3 tablespoons of butter. Add finely minced onion and sauté for 5 minutes until translucent.
  3. Stir in minced garlic, along with salt and ground black pepper. Cook for an additional 30 seconds until fragrant.
  4. Pour in 1 cup of chicken stock and 1 cup of heavy cream, stirring well. Bring to a gentle simmer over medium heat.
  5. Add the thinly sliced russet potatoes to the skillet, ensuring they are fully coated in the creamy sauce. Cover and reduce heat, cooking for about 15-20 minutes until nearly tender.
  6. Grease an 8x8 inch baking dish with the remaining butter, then transfer the potato mixture into the dish and spread it evenly.
  7. Generously sprinkle shredded cheese over the top of the potatoes.
  8. Place the baking dish in the preheated oven and bake for 10-15 minutes, or until the cheese is golden brown and edges are bubbly.
  9. Let the dish rest for a few minutes before serving. Garnish with chopped parsley if desired.
