Au Gratin Potatoes (Printable)

Tender potatoes baked in creamy garlic sauce with melted Gruyère and a golden crust

# Ingredient List:

→ Vegetables

01 - 3 lbs Yukon Gold or Russet potatoes, peeled and thinly sliced
02 - 2 cloves garlic, minced

→ Dairy

03 - 4 tbsp unsalted butter
04 - 2 cups heavy cream
05 - 2 cups grated Gruyère cheese
06 - ½ cup grated Parmesan cheese

→ Spices & Seasonings

07 - 1 tsp salt
08 - ½ tsp freshly ground black pepper
09 - ¼ tsp freshly grated nutmeg

# How To Make:

01 - Preheat oven to 375°F. Generously grease a 9x13 inch baking dish with butter.
02 - In a saucepan over medium heat, melt butter. Add minced garlic and sauté for 1 minute until fragrant. Stir in heavy cream, salt, pepper, and nutmeg. Heat until just simmering, then remove from heat.
03 - Arrange half of the sliced potatoes in the prepared dish. Pour over half of the cream mixture. Sprinkle with half the Gruyère and Parmesan cheeses.
04 - Layer the remaining potatoes, pour over the remaining cream mixture, and sprinkle with the remaining cheeses.
05 - Cover with foil and bake for 40 minutes until potatoes begin to soften.
06 - Remove foil and continue baking for 20 minutes, or until the top is golden and bubbling, and the potatoes are tender when pierced with a knife.
07 - Let rest for 10 minutes to allow the sauce to thicken slightly for easier serving.

# Expert Hints:

01 -
  • The way the cream sauce bubbles up through the potato layers creating little rivers of golden goodness
  • That moment when you pull off the foil and the cheese has turned into this gorgeous golden crust that makes the whole kitchen smell incredible
02 -
  • Slice your potatoes as evenly as possible, about 1/8 inch thick, so they all finish cooking at the same time
  • A mandoline makes perfectly uniform slices, but a sharp knife and steady hand work just fine
  • Do not skip the resting time or the sauce will be too runny when you serve it
03 -
  • Warm your cream slightly before adding it to the hot butter so it does not separate
  • Grate your own cheese rather than buying pre-grated for better melting and flavor
