Ingredients
Creating the perfect au gratin potatoes starts with high-quality ingredients that deliver rich, creamy, and indulgent layers. Opt for starchy potatoes like Russets or Yukon Golds—they hold their shape while soaking up that cheesy goodness. Freshly grated cheese is a game-changer; pre-shredded varieties often contain anti-caking agents that can affect the sauce’s texture.
Here’s what you’ll need:
- Potatoes: 2 lbs Russet or Yukon Gold potatoes, peeled and thinly sliced (the starchier, the better for that creamy texture).
- Cheese: 2 cups freshly shredded sharp cheddar (or Gruyère for a nuttier flavor—don’t skimp on quality here).
- Butter: 3 tbsp unsalted butter (for richness in the sauce and greasing the dish).
- Milk: 1 ½ cups whole milk (or half-and-half for extra creaminess).
- Heavy Cream: ½ cup heavy cream (this is the secret to that luxurious sauce).
- Flour: 3 tbsp all-purpose flour (to thicken the sauce).
- Garlic: 2 cloves minced garlic (for a subtle, savory kick).
- Salt & Pepper: 1 tsp salt and ½ tsp black pepper (adjust to taste for seasoning).
- Nutmeg: A pinch of freshly grated nutmeg (optional, but it adds a warm, earthy depth).
*Substitutions:* No heavy cream? Use all whole milk mixed with an extra tablespoon of butter. Out of cheddar? Try a blend of Monterey Jack and Parmesan for a tangy twist.
*Non-Negotiables:* Freshly grated cheese and starchy potatoes are must-haves—they’re the foundation of this dish’s creamy, cheesy perfection.
*Little Wins:* Sprinkle a handful of breadcrumbs or extra shredded cheese on top for a golden, crispy crust that’s irresistible.
How to Make the Best Creamy Au Gratin Potatoes Guide

Gradually whisk in warm milk until the mixture is smooth and thickened. Warm milk prevents lumps, and whisking guarantees a silky texture.
Remove from heat and stir in shredded cheese until melted. Use sharp cheddar for bold flavor, or mix cheeses like Gruyère for a richer taste.
Reserve some cheese for the topping.
Pour half of the cheese sauce over the first layer of potatoes. Spread evenly to coat every slice, securing creamy results.
Repeat with the remaining potato slices and cheese sauce. Layer neatly and sprinkle the reserved cheese on top for a golden, cheesy crust.
Cover the dish with foil and bake for 45 minutes. The foil traps steam, softening the potatoes without drying them out.
Remove the foil and bake for an additional 20–25 minutes, or until the top is bubbly and golden brown. This step crisps up the topping for a satisfying finish.
Let the dish rest for 10 minutes before serving. This allows the sauce to thicken slightly and makes it easier to slice and serve.

Chef Tips
One of the easiest ways to elevate your homemade au gratin potatoes is by selecting the right type of cheese. I prefer Gruyère or sharp cheddar for their flavor and meltability.
Always slice potatoes thinly and evenly for consistent cooking.
Season each layer generously, and don’t skip the nutmeg—it adds depth.
Bake uncovered for a golden crust, and let it rest before serving to set the creamy texture.
