Au Gratin Potatoes (Printable)

Layers of tender potatoes in a creamy garlic sauce, topped with melted cheeses and baked until golden brown.

# What You'll Need:

→ 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 It:

01 - Preheat oven to 375°F. 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. Layer the remaining potatoes, pour over the remaining cream mixture, and sprinkle with the remaining cheeses.
04 - Cover with foil and bake for 40 minutes. Remove foil and continue baking for 20 minutes, or until the top is golden and the potatoes are tender.
05 - Let rest for 10 minutes before serving to allow the sauce to set.

# Expert Suggestions:

01 -
  • The cream sauce infuses every single potato slice with flavor instead of sitting on top
  • That golden cheesy crust creates the most incredible contrast against the tender potatoes underneath
  • It actually tastes better reheated the next day, if there's any left
02 -
  • Slice your potatoes as evenly as possible, or some will turn to mush while others stay crunchy
  • A mandoline makes this infinitely faster and more consistent than hand slicing
  • If the top browns too quickly, tent loosely with foil
03 -
  • Try adding fresh thyme leaves between layers for an herbal note that complements the cream
  • Pat your potato slices dry before layering if they seem especially wet
  • Place your baking dish on a sheet pan to catch any potential overflow
