Step-by-Step Cooking Instructions
How to Cook Potatoes Au Gratin: A Step-by-Step Guide
- Preheat the Oven: Start by preheating your oven to 375°F (190°C).
- Prepare the Potatoes: Wash and peel the potatoes, then slice them thinly, about ⅛ inch thick.
- Slice the Onion: Thinly slice the onion and set aside.
- Make the Roux: In a medium saucepan, melt the butter over medium heat. Add the flour and dry mustard powder, stirring constantly until the mixture is smooth and bubbly.
- Add the Milk: Gradually whisk in the milk, continuing to stir until the sauce thickens and comes to a boil.
- Add the Cheese: Remove the saucepan from heat and stir in the shredded cheddar and gruyere cheeses until melted and smooth. Season with salt and pepper to taste.
- Layer the Ingredients: In a greased baking dish, layer half of the sliced potatoes, followed by a layer of sliced onions. Pour half of the cheese sauce over the onions. Repeat with the remaining potatoes, onions, and cheese sauce.
- Bake: Cover the dish with aluminum foil and bake for 45 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the top is golden brown and the potatoes are tender.
- Rest and Serve: Allow the dish to rest for 10 minutes before serving to let the flavors meld together.
Common Mistakes to Avoid
- Using the Wrong Potatoes: Stick to starchy potatoes like red or russet for the best texture.
- Not Slicing Evenly: Ensure your potato slices are uniform to cook evenly.
- Skipping the Rest Period: Allowing the dish to rest after baking helps the sauce thicken and the flavors to combine.
