Equipment Needed for Potato Gratin
To prepare potato gratin, you’ll need the following equipment:
- Large skillet
- 9 by 13 inch casserole dish
- Large glass measuring cup
- Sharp knife for slicing potatoes
- Cutting board
What You Need to Make Potato Gratin
- 3 tablespoons salted butter
- 1 yellow onion, thinly sliced
- Kosher salt and black pepper to taste
- 1/4 cup dry white wine, such as Pinot Grigio
- 1 clove garlic, chopped
- 1 tablespoon chopped fresh thyme
- 2 cups heavy cream
- 1 cup whole milk
- 1 pinch cayenne
- 3/4 cup shredded Gruyere cheese
- 3/4 cup shredded cheddar cheese
- 6 russet or Yukon gold potatoes, cut into 1/8-inch-thick slices
How to Cook Potato Gratin Step by Step
To begin, preheat your oven to 350 degrees F. In a large skillet, melt the butter over medium-high heat. Once the butter is melted, add the thinly sliced onions. Stir occasionally for about 10 minutes or until the onions soften and turn translucent.
Next, pour in the dry white wine. Allow the mixture to cook for another five minutes, stirring frequently, until the onions become deeply caramelized, giving them a rich flavor. Add the chopped garlic and fresh thyme to the skillet, and sprinkle with salt and pepper to taste. Cook for an additional two minutes, then remove the skillet from the heat and set it aside.
Now it’s time to prepare your casserole dish. Butter a 9 by 13 inch casserole dish generously. In a large glass measuring cup, combine the heavy cream, whole milk, a pinch of cayenne, salt, and pepper. Stir well, then add in the Gruyere cheese.
It’s time to start layering. Pour one-third of the milk mixture into the bottom of the buttered baking dish. Next, arrange one-third of the potato slices over the cream layer, followed by half of the caramelized onions. Repeat the process by pouring another one-third of the milk mixture on top, layering another one-third of the potatoes, and adding the remaining onions. Finish by layering the remaining potato slices, and pour the rest of the milk mixture over the top. Ensure that the potatoes are evenly covered with the creamy mixture.
Cover the casserole dish with aluminum foil and place it in the oven. Bake for 1 hour and 45 minutes to 2 hours. The goal is to have the potatoes tender and infused with all the flavors.
After the baking time is completed, carefully remove the foil. Sprinkle the shredded cheddar cheese evenly over the top. Return the dish to the oven and bake for another 20 minutes, or until the cheese is melted and turns a lovely golden brown color.
Once ready, remove the gratin from the oven. Let it sit for a few minutes before serving. This dish is delicious when warm and topped with a little fresh thyme for added flavor.
If you’re looking to make this dish ahead of time, you can prepare it up to the point of covering with foil and baking. Chill it and store it in the refrigerator for up to four days. When ready to enjoy, bring it to room temperature, add the cheddar cheese, and bake for an additional 20 to 30 minutes until it is heated through.
How to Make Potato Gratin
Crafting potato gratin is simpler than it sounds. The technique involves layering fresh, thin slices of potatoes with creamy cheese blends and savory onions.
Start by caramelizing the onions for rich flavor that elevates the dish. The cream and cheese mixture adds a luxurious finish that binds the layers together. It requires patience, but the result is rewarding.
Keep in mind that the key to a great gratin is the texture of your potatoes. Thin slices ensure even cooking and help achieve that deliciously creamy result.
How to Serve Potato Gratin
Potato gratin is best served hot and straight out of the oven. You can scoop out generous portions using a spatula. The layers should be visible, showcasing the creamy potatoes and melted cheese.
Consider garnishing with fresh thyme leaves for a pop of color and added flavor. It’s a visually appealing dish that will certainly catch anyone’s eye at the table.
Serve it either as a main dish for a vegetarian meal or as a hearty side. It complements many proteins like roast chicken, grilled meats, or even a simple salad.
What to Serve with Potato Gratin
This dish pairs wonderfully with various options. For a classy meal, consider serving it alongside a roast chicken or herb-crusted pork.
If you want something lighter, a fresh green salad with vinaigrette will balance the richness of the gratin. You might also serve it with steamed vegetables for a complete and nutritious meal.
Don’t forget about wine! A crisp white wine like Sauvignon Blanc or a light red like Pinot Noir can enhance the flavors of the gratin.
How to Store Potato Gratin
If you happen to have leftovers, storing potato gratin is simple. Allow it to cool completely before transferring it to an airtight container.
Store the container in the refrigerator, where it will keep for up to four days. To reheat, place it in the oven until warmed throughout. Cover it with foil to prevent over-browning.
You can also freeze potato gratin. Wrap it tightly in plastic wrap and then place it in a freezer-safe container. It will last for up to three months in the freezer. When ready to eat, thaw in the refrigerator overnight and reheat in the oven.
Tips to Make Potato Gratin
To ensure the best potato gratin possible, using the right type of potatoes is crucial. Yukon gold or russet potatoes work well due to their starch content, which helps create a creamy texture.
Slice the potatoes evenly; a mandoline can make this task quicker and more uniform. Be careful with your fingers while using one, though!
Don’t skimp on the cheese; using good quality Gruyere and cheddar will make a big difference in flavor.
Lastly, make sure your onions are caramelized well, as they contribute essential sweetness to the dish.
Variation (If Any)
While the classic potato gratin is delicious, you can make a few variations to suit your taste.
For a twist, consider incorporating vegetables. Thinly sliced zucchini or spinach can add color and nutrients.
You could also experiment with different cheese types. Sharp cheddar or fontina can bring unique flavors to your gratin.
Adding cooked bacon or prosciutto can introduce a savory element that is hard to resist.
