Cooking Tips

If you don’t have Gruyere, you can substitute with cheddar cheese.

This is a good time to taste the sauce and add more salt and pepper if needed.

The old-fashioned way is just to use a knife and I love the santoku knife because it has the ridges in the blade that keep the potatoes from sticking to the knife.

The food processor will quickly give you uniformly thin sliced potatoes.

Keeping them thinly sliced will ensure even baking.

I do like to cut off the tip of the potato and attach it to the food holder just to keep my fingers safe.

Cream cheese on top creates a golden cheesy crust that seals in the bubbly juices underneath.

Covering the top tightly with foil will promote even cooking.

If you cut them a little thicker, it will take a little longer than the oven.

I like to cut them nice and thin, which cuts down the baking time. For another delicious and quick meal, try our easy one-pan ground beef and rice with cheese.

That Gruyere cheese, it tastes good, it adds so much like sophisticated flavor, it’s subtle. It doesn’t overpower the dish, even though there’s a whopping two cups in this casserole.

Serving Suggestions

I do love to add a little bit of chives for garnish just because it gives it a little pop of color, pop of flavor.

This pairs well with just about any protein you can serve it with the holiday turkey or a prime rib or even a beef tenderloin or chicken. For a delicious fish option, consider our easy baked salmon with garlic lemon parsley glaze, it goes well with just about anything and it’s so simple.

Easy Creamy All Gratin Potatoes Recipe with Cheesy Sauce

This All Gratin Potatoes recipe is a creamy, cheesy, and utterly delicious side dish that, despite its fancy name, is surprisingly easy to make. Featuring thinly sliced potatoes baked in a rich, velvety cheese sauce, it’s perfect for holidays or a comforting everyday meal.

  • 3-4 lbs (about 6-8 medium) Russet potatoes
  • 4 tablespoons unsalted butter
  • 1/4 cup all-purpose flour
  • 2 cups whole milk
  • 1 cup heavy whipping cream
  • 2 cups (approx. 6 oz) grated Gruyere cheese, divided
  • 1 teaspoon salt
  • 1/2 teaspoon freshly ground black pepper
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • Fresh chives, for garnish (optional)
  1. Preheat your oven to 350 degrees Fahrenheit (175°C). Butter a 3-quart or 9×13-inch casserole dish and set it aside.
  2. Grate the Gruyere cheese and set it aside, keeping it divided for sauce and topping as directed below.
  3. Set your Dutch oven or a soup pot over medium heat. Melt in 4 tablespoons of unsalted butter.
  4. Add a quarter cup of flour to the melted butter. Whisk that together for 2 minutes until golden, creating a roux.
  5. Gradually pour in the milk followed by the heavy whipping cream, whisking constantly to prevent lumps.
  6. Now add salt, freshly ground black pepper, onion powder, and garlic powder. Continue whisking until your sauce has thickened to your desired consistency.
  7. Remove the sauce from the heat. Stir in 1 cup of the grated Gruyere cheese. Whisk until the cheese has melted and is fully incorporated into the sauce. Cover the sauce and set it aside to keep warm while you prep the potatoes.
  8. Peel the potatoes, or if you prefer to leave the skin on, use a brush to scrub the outsides thoroughly. Thinly slice the potatoes to a thickness of approximately 1/8 inch. Using a mandoline or food processor is recommended for uniform slices.
  9. Give the warm cream sauce a quick stir. Add all the thinly sliced potatoes to the sauce. Using a spatula, make sure that they are pretty evenly coated.
  10. Transfer your saucy potatoes into your buttered casserole dish. Spread them out evenly in the pan.
  11. Once you’ve flattened out the top, sprinkle on your remaining 1 cup of grated Gruyere cheese.
  12. Cover the casserole dish tightly with foil.
  13. Bake in the center of the preheated oven at 350 degrees Fahrenheit (175°C) for 60 minutes.
  14. Next, remove the foil. Continue baking for another 15 to 30 minutes, or until the potatoes are tender when pierced with a fork and the top is golden brown. For an even crispier, golden brown crust, you can broil for one to two minutes at the very end, watching carefully to prevent burning.
  15. Let the gratin rest out of the oven for 15 minutes before serving, allowing the sauce to set.
  16. To serve, just scoop it out and garnish with fresh chives, if desired.
