Why You’ll Love This Leek Gratin

Leek Gratin is a side dish that’s both indulgent and flavorful, perfect for elevating your meal.

What makes this dish so special is the versatility. While it’s a great addition to Thanksgiving, it’s also perfect for weeknight dinners, special occasions, or holiday feasts.

Ingredients

• 4 leeks, trimmed and sliced
• ½ cup heavy cream
• ½ cup Gruyère cheese, grated
• 2 tablespoons butter
• Salt and pepper to taste

Instructions

1. Preheat the Oven:
   Preheat your oven to 375°F (190°C) and grease a baking dish to prevent sticking.
2. Prepare the Leeks:
   Trim the dark green tops of the leeks and the root end, then slice the leeks into rounds. Be sure to rinse them thoroughly to remove any dirt or grit that may be trapped between the layers. Leeks are often sandy, so it’s essential to clean them well before cooking.
3. Sauté the Leeks:
   Heat the butter in a skillet over medium heat. Once the butter has melted, add the leeks and cook, stirring occasionally, for about 5–7 minutes. The leeks should become soft and tender, and you’ll want to season them with salt and pepper to taste during the sautéing process.
4. Assemble the Gratin:
   Transfer the sautéed leeks to the greased baking dish, spreading them out evenly. Pour the heavy cream over the leeks, ensuring it’s evenly distributed. Then, sprinkle the grated Gruyère cheese generously on top, ensuring a good coverage over the leeks.
5. Bake the Gratin:
   Place the baking dish in the preheated oven and bake for 20 minutes, or until the top is golden and bubbling. The cheese should melt and form a delicious, crispy crust on top of the creamy leeks.
6. Serve:
   After baking, let the gratin rest for a few minutes before serving. This allows the dish to firm up slightly, making it easier to serve. Serve warm and enjoy the creamy, cheesy goodness of this delectable gratin!

Additional Tips

1. Use a variety of cheese: While Gruyère is traditional, you can experiment with other cheeses like Swiss, cheddar, or even goat cheese for different flavor profiles.
2. Caramelize the leeks for extra flavor: For an even richer flavor, you can caramelize the leeks over lower heat for a longer period, allowing them to develop a sweet, golden brown color.
3. Add breadcrumbs for crunch: For extra texture, top the gratin with a sprinkle of breadcrumbs before baking. The breadcrumbs will form a crispy topping that contrasts beautifully with the creamy filling.
4. Use whole milk or half-and-half: If you want a slightly lighter version, you can substitute the heavy cream with whole milk or half-and-half. Keep in mind the texture will be a bit less rich.
5. Make it ahead: This gratin can be made a day in advance. Simply assemble it, cover, and refrigerate. When ready to serve, bake it as directed, adding a few extra minutes if needed.
