Potatoes Au Gratin Recipe
Ingredients
To serve 6 people, you’ll need:
- 2 pounds of russet or Yukon Gold potatoes (peeled and thinly sliced)
- 2 cups heavy cream
- 1 cup whole milk
- 2 garlic cloves (minced)
- 2 cups shredded Gruyère cheese (or a blend of Gruyère and Parmesan)
- 2 tablespoons unsalted butter
- Salt and freshly ground black pepper
- Optional: Fresh thyme or parsley for garnish
Step-by-Step Instructions
1. Preheat the Oven
Set your oven to 375°F (190°C). Grease a baking dish with butter to prevent sticking.
2. Prepare the Potatoes
Peel and thinly slice the potatoes evenly. Use a mandoline for precision, ensuring even cooking.
3. Make the Creamy Sauce
In a medium saucepan, heat heavy cream, milk, minced garlic, salt, and pepper over medium heat. Stir until warm, but do not let it boil.
4. Layer the Potatoes and Sauce
Arrange one-third of the potato slices in an overlapping pattern in the greased baking dish. Pour a portion of the cream mixture over the layer and sprinkle with shredded cheese. Repeat this process two more times, finishing with a generous cheese topping.
5. Bake the Dish
Cover the dish with aluminum foil and bake for 45 minutes. Remove the foil and bake for another 20–30 minutes, or until the top is golden and the potatoes are tender when pierced with a fork.
6. Rest and Serve
Let the dish cool for 5–10 minutes before serving. Garnish with fresh thyme or parsley for added flavor and visual appeal.
Tips for Making Perfect Potatoes Au Gratin
1. Choose the Right Potatoes
Russet potatoes are ideal for their starchiness, which creates a creamy texture. Yukon Gold potatoes add a naturally buttery flavor.
2. Use High-Quality Cheese
Gruyère cheese is traditional, but you can experiment with other options like cheddar, fontina, or a mix. High-quality cheese ensures a rich and flavorful dish.
3. Slice Potatoes Evenly
Uniform slices cook more evenly. A mandoline slicer is a helpful tool for achieving this.
4. Avoid Oxidation
Slice the potatoes just before assembling the dish to prevent them from browning. If necessary, submerge sliced potatoes in cold water, then pat dry before use.
FAQs About Potatoes Au Gratin
1. Can I Make Potatoes Au Gratin Ahead of Time?
Yes, you can assemble the dish up to 24 hours in advance and refrigerate it. When ready to serve, bake it fresh for the best results.
2. What’s the Difference Between Scalloped Potatoes and Potatoes Au Gratin?
Scalloped potatoes are made with a creamy sauce but typically without cheese, while potatoes au gratin include cheese for added richness and flavor.
3. Can I Substitute Dairy Ingredients?
You can use non-dairy cream alternatives for a lighter version, but the taste and texture may differ slightly. For a healthier option, substitute half-and-half for heavy cream.
4. How Should I Store Leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) to restore the creamy texture and crispy topping.
