Ingredients

  • russet potatoes

    peeled

    6 medium
  • onion

    sliced thin

    1 small
  • butter
    ¼ c
  • all-purpose flour
    ¼ c
  • whole milk
    1 ½ c
  • freshly shredded cheddar cheese
    2 c
  • garlic powder
    1 tsp
  • salt
    1 tsp
  • pepper
    1 tsp
  • shredded gruyère cheese

    or use more cheddar

    ½ c
  • fresh chopped chives or parsley

    for garnish

Directions

  1. 1

    Preheat your oven to 375°F. Spray a 2-quart casserole pan with nonstick spray.

  2. 2

    Thinly slice the potatoes to no more than ⅛ inch thick. I highly recommend slicing the potatoes using a mandoline.

  3. 3

    Arrange half the potatoes in the casserole pan and top with the onions. Top the onions with the remaining potatoes.

  4. 4

    In a medium saucepan, melt the butter. Slowly stir in the flour and cook for 2 minutes until no white streaks remain, stirring the entire time. Slowly whisk in the milk until well combined. Mix in the cheddar cheese, garlic powder, salt, and pepper until the cheese has melted.

  5. 5

    Pour the cheese sauce over the potatoes.

  6. 6

    Cover the pan tightly with aluminum foil and bake for 45 minutes.

  7. 7

    Uncover the casserole dish and sprinkle the Gruyere cheese over the top. Bake for an additional 35-45 minutes until it is golden brown and bubbling.

  8. 8

    Let rest 15 minutes so the sauce thickens and it's easier to cut, garnish with fresh chopped parsley or chives, then slice and serve.

Cheesy Potato Gratin Recipe

Cheesy Potato Gratin Recipe

The principal innovation here is placing the sliced potatoes in the casserole dish vertically, on their edges, rather than laying them flat as in a standard gratin, in order to get those crisp ridges on top. Allow extra time for the task of slicing the potatoes, for which it's helpful to have a mandoline or food processor (though not necessary, strictly speaking). And do buy extra potatoes, just in case; you want to pack the potatoes tightly and keep them standing up straight. Discover more ideas for the big day at NYT Cooking.

About this Recipe

Craving a classic, comforting side dish that elevates any meal, from holiday feasts to weeknight dinners? These Au Gratin Potatoes deliver rich, creamy, and cheesy goodness that will quickly become a family favorite.

Why This Recipe Works

This recipe shines by combining thinly sliced russet potatoes and savory onions with a luscious, buttery sauce and not one, but two types of cheese. The blend of sharp cheddar and nutty Gruyère creates an irresistible flavor profile, ensuring every bite is deeply satisfying. What's more, you can even prepare this dish in advance, making it a stress-free option for busy days.

What to Expect

Prepare for a hearty side that boasts tender, thinly sliced potatoes swimming in a rich, creamy sauce, all blanketed by a golden-brown, bubbly cheese topping. The subtle sweetness of the onion perfectly complements the earthy potatoes and the sharp, tangy cheeses. You'll love how the layers of flavor build up to create a truly comforting and indulgent experience, perfect for pairing with a holiday ham or a simple weeknight steak.

Customization & Variations

This versatile dish offers plenty of room for personalization. While the recipe calls for Gruyère cheese, you can easily substitute it with more cheddar for an equally delicious, perhaps sharper, flavor. For a touch of freshness and vibrant color, consider garnishing with fresh chopped chives or parsley just before serving.

Serving & Context

These Au Gratin Potatoes are the quintessential side for special occasions, like your holiday ham or turkey. They also make an excellent, comforting accompaniment to everyday meals such as pork chops or steak, providing a substantial and flavorful counterpoint.
