With its layers of sweet potatoes, rich cream, and a hint of cheese, this gratin not only satisfies the palate but also serves as a beautiful centerpiece on your dining table. Follow this simple guide to create your own French Sweet Potato Gratin at home.

Ingredients You'll Need

  • 2 large sweet potatoes
  • 1 cup heavy cream
  • 1 cup grated Gruyère cheese (or any cheese of your choice)
  • 2 tablespoons unsalted butter
  • 2 cloves garlic, minced
  • 1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)
  • Salt and freshly ground black pepper, to taste
  • 1/2 cup breadcrumbs (optional, for crunch)

Preparation Steps

Step 1: Preheat Your Oven

Preheat your oven to 400°F (200°C). This temperature will ensure your gratin is baked evenly.

Step 2: Slice the Sweet Potatoes

Peel the sweet potatoes and slice them thinly, about 1/8 inch thick. A mandoline slicer works perfectly for this task, providing uniform pieces that cook evenly.

Step 3: Prepare the Cream Mixture

In a saucepan over medium heat, melt the butter and sauté the minced garlic until fragrant. Add the heavy cream, thyme, salt, and pepper, stirring well to combine. Heat the mixture until it’s warm but not boiling, allowing the flavors to meld.

Step 4: Assemble the Gratin

In a greased baking dish, arrange a layer of sweet potato slices, slightly overlapping each piece. Pour a portion of the cream mixture over the sweet potatoes, followed by a sprinkling of Gruyère cheese. Repeat the layering process until all sweet potatoes are used, finishing with a layer of cream on top and a generous amount of cheese.

Step 5: Add Breadcrumbs (Optional)

If you like a crunchy top, sprinkle the breadcrumbs evenly over the cheese layer. This will create a delightful texture contrast once baked.

Step 6: Bake the Gratin

Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes. Remove the foil and continue to bake for an additional 15-20 minutes, or until the top is golden brown and bubbly.

Serving Suggestions

Once baked, allow your French Sweet Potato Gratin to cool for about 10 minutes before serving. This dish pairs wonderfully with roasted meats, a fresh green salad, or even as a stand-alone vegetarian option. Garnish with extra thyme leaves for an added touch of elegance.

Storage Tips

If you have leftovers, store the gratin in an airtight container in the refrigerator for up to three days. To reheat, simply place it in the oven at 350°F (175°C) until warmed through.

Conclusion

Making French Sweet Potato Gratin is easier than you might think. With its creamy texture and rich flavors, this dish is sure to impress your family and friends. Enjoy this classic French recipe that brings warmth and sophistication to your dinner table!
