How to Prepare the Perfect Cheesy Au Gratin Potatoes: Step-by-Step Guide
Creating this cheesy au gratin potatoes involves a few easy steps that lead to a dish full of cheesy goodness. Start by preheating your oven to 375°F, which sets the stage for even baking. The process takes about 30 minutes to prepare and around 1 hour and 15 minutes total, yielding 8 servings that are perfect for sharing.
- Begin by greasing a 9-inch square baking dish. Arrange the 2 ½ pounds of sliced Yukon gold potatoes and ½ medium yellow onion in slanted rows with space between the slices for even cooking.
- In a saucepan, melt the 3 tablespoons of salted butter over medium heat. Whisk in the ¼ cup of all-purpose flour to form a paste, then gradually add the 1 ½ cups of whole milk or unsweetened almond milk, stirring until the mixture thickens.

FAQs: Frequently Asked Questions About Cheesy Au Gratin Potatoes
What’s the difference between scalloped potatoes and au gratin potatoes?
Scalloped potatoes are typically made with a creamy sauce of butter and broth layered with sliced potatoes, usually without cheese. Au gratin potatoes include a cheese sauce between layers of thinly sliced potatoes and are topped with breadcrumbs or extra cheese for a crispy topping. The cheese adds a richer flavor and a golden crust distinguishes au gratin from scalloped potatoes.
Can I prepare cheesy au gratin potatoes ahead of time, and how should I store them?
Yes, you can prepare au gratin potatoes up to three days in advance. After assembling the dish, cover it tightly with foil and refrigerate. When ready to bake, add extra baking time (about 15-20 minutes) since the dish will be cold. Leftover baked potatoes should be stored in an airtight container in the fridge and can be reheated in the oven or microwave within five days.
What type of potatoes work best for au gratin potatoes?
Yukon gold potatoes are ideal due to their creamy texture and buttery flavor, which hold up well during baking. Russet potatoes can be used but may become too fluffy or dry. Evenly slicing potatoes about 1/8 inch thick—preferably with a mandoline slicer—helps ensure uniform cooking and a consistent texture throughout the dish.
Can I substitute the cheese in au gratin potatoes, and which cheeses work well?
Yes, you can customize the cheese blend. Traditional recipes use Gruyère, cheddar, or mozzarella. If you don’t have Gruyère, extra sharp cheddar, smoky gouda, or spicy cheeses add interesting flavors. Avoid pre-shredded cheeses if possible, as freshly shredded cheese melts better and creates a smoother sauce.
Is it necessary to soak the sliced potatoes before cooking?
Soaking sliced potatoes in cold water for 20-30 minutes helps prevent browning caused by oxidation and removes some excess starch. This step keeps the potato slices looking fresh and helps them cook more evenly. Drain and dry the slices thoroughly before layering for best results.
