Ingredients Overview
- Russet Potatoes: These starchy potatoes yield the creamiest texture.
- Cheese Trio: Cheddar adds sharpness, provolone brings a smooth creaminess, and Parmesan delivers a savory punch.
- Garlic and Onion: Subtle aromatics that enhance the dish without overpowering it.
- Heavy Cream: Creates the luscious, creamy base.
- Fresh Parsley: Adds a pop of color and a fresh flavor contrast.
How to Make the Recipe
Step 1: Preheat the Oven
Preheat your oven to 425°F (220°C) and prepare an 8×8-inch baking dish. Use butter to grease the dish, ensuring the potatoes won’t stick. This step also helps create a golden crust. Set the dish aside for later use.
Step 2: Sauté the Aromatics
Melt 2 tablespoons of butter in a large pot over medium heat. Add finely minced onion and cook until soft and translucent, about 5 minutes. Stir in garlic, cooking for 30 seconds to release its aroma. Season with salt and pepper for balanced flavor.
Step 3: Simmer the Potatoes
Add chicken stock, heavy cream, and sliced potatoes to the pot. Bring the mixture to a gentle simmer over medium-low heat. Cover with a lid and cook for 15–20 minutes, stirring occasionally. The potatoes should be tender but not falling apart.
Step 4: Assemble the Dish
Transfer the creamy potato mixture into the buttered baking dish. Spread it out evenly to create a uniform layer. Sprinkle the cheddar, provolone, and Parmesan cheeses generously over the top. Ensure the cheese is evenly distributed for a perfect melt.
Step 5: Bake to Perfection
Place the baking dish in the preheated oven and bake for 10–15 minutes. Watch for the cheese to become bubbly and golden brown. This step creates the signature molten cheese topping. Remove from the oven once perfectly baked.
Step 6: Garnish and Serve
Sprinkle freshly chopped parsley over the hot dish for a vibrant finish. Let it rest for a few minutes before serving to allow the flavors to meld. Serve immediately and enjoy this creamy, cheesy masterpiece with your loved ones!
Tips for the Best Recipe
- Use freshly grated cheese for the best melt and flavor.
- Slice potatoes evenly (1/8-inch thick) to ensure uniform cooking.
- Avoid boiling the cream mixture to prevent curdling
Variations to Try
- Swap russet potatoes for Yukon Gold for a buttery texture.
- Use Gruyère or Fontina instead of provolone for a gourmet twist.
- Add fresh thyme or rosemary for an aromatic touch.
- Make it spicy with a dash of cayenne or red pepper flakes.
