Step-by-Step Preparation of Potatoes au Gratin
Creating the perfect Potatoes au Gratin is easier than you think! Let's break it down into simple steps that are both friendly and helpful, ensuring you’ll have a glorious dish that everyone will love.
Gather Your Ingredients
Before diving into the kitchen, gather all your ingredients. Here’s what you’ll need:
- 1 ½ cups of full-fat cream (any type is great)
- 2 garlic cloves, minced
- 30g/2 tablespoon unsalted butter, melted
- 1.25 kg/2.5 lb starchy potatoes (like Russet or Sebago)
- 1 teaspoon salt
- ¼ teaspoon pepper
- 2 ½ cups freshly grated gruyère cheese (or your favorite melting cheese)
- 2 teaspoon fresh thyme leaves (optional but highly recommended)
Once you have everything, you’ll feel organized and ready to cook!
Prepare the Cream Mixture
In a jug, mix the melted butter, full-fat cream, and minced garlic until well combined. This creamy blend gives the dish its rich flavor. Preheat your oven to 180°C/350°F to ensure it’s hot and ready for your delightful creation!
Slice and Layer the Potatoes
Peel the potatoes and slice them into ⅛-inch (3 mm) thick rounds. If you have a mandoline slicer, this is the time to use it! The uniform slices ensure even cooking.
Now, it’s time to layer! Start by spreading one-third of the potatoes in your baking dish. Pour over one-third of the cream mixture, sprinkle a third of the salt, pepper, and thyme, then add ¾ cup of grated cheese. Repeat this process for the second and third layers, reserving the last bit of cheese for the final topping!
Bake the Potatoes Covered
Cover your baking dish tightly with a lid or aluminum foil. This steams the potatoes and helps them become wonderfully tender. Bake for about 1 hour and 15 minutes, or until the potatoes are soft enough to pierce easily with a knife. You may need to adjust the time slightly depending on your dish and oven.
Add Cheese and Bake Again
Once your potatoes are soft, it’s time for the grand finale! Remove the cover, sprinkle the top with the remaining cheese, and return it to the oven. Bake uncovered for another 10 to 15 minutes, or until the cheese is bubbly and golden brown.
Allow your Potatoes au Gratin to stand for about 5 minutes before serving. This dish is perfect for making ahead; simply follow the baking instructions, cool, and refrigerate until ready to heat and serve.
Enjoy this creamy, cheesy delight that is sure to impress friends and family alike!
