Ingredients
- 4 large russet potatoes, thinly sliced
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups heavy cream
- 1 cup whole milk
- 1 teaspoon garlic powder
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 1 cup shredded sharp cheddar cheese
- 1 cup shredded Gruyère cheese
- ¼ cup grated Parmesan cheese
- Fresh parsley, for garnish
Creamy, cheesy, and perfectly baked—this dish delivers big flavor in every bite.
Instructions
1. Prepare the Potatoes
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. Thinly slice the potatoes using a sharp knife or mandoline for even cooking.
2. Make the Cheese Sauce
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1–2 minutes to form a roux.
Slowly add the cream and milk while whisking constantly. Cook until the sauce thickens, about 5 minutes.
Add garlic powder, salt, and pepper. Remove from heat, then stir in the cheddar, Gruyère, and Parmesan until melted and smooth.
3. Layer the Dish
Place half the sliced potatoes in the baking dish in an even layer. Pour half of the cheese sauce over the potatoes.
Repeat with the remaining potatoes and sauce.
4. Bake
Cover the dish with foil and bake for 40 minutes. Remove the foil and continue baking for another 20–25 minutes, or until the top is golden brown and bubbly.
5. Serve
Allow the potatoes to rest for 5–10 minutes before serving. Garnish with chopped parsley for a fresh finish.

Expert Tips
- Try Yukon Golds if you prefer a creamier, buttery texture.
- Shred your own cheese for a smoother melt—pre-shredded cheese contains additives that affect texture.
- Want a crispier top? Broil the dish for the last 2–3 minutes of baking time.
- For added flavor, mix in chopped cooked bacon or a pinch of cayenne pepper.
Whether served at a dinner party or on a cozy night in, these potatoes are a cheesy, comforting crowd-pleaser that everyone will remember. ❤️
