Description
A delicious and creamy cheesy sweet potato gratin that is perfect for any occasion.
Ingredients
Scale
- 2 pounds sweet potatoes, peeled and thinly sliced
- 1 cup heavy cream
- 2 cups shredded cheese (such as Gruyère or cheddar)
- 2 cloves garlic, minced
- 1 teaspoon fresh thyme, chopped (or 1/2 teaspoon dried thyme)
- Salt and pepper to taste
- 2 tablespoons unsalted butter
- 1/4 teaspoon nutmeg (optional)
Instructions
- Preheat Oven: Set your oven to 375°F (190°C).
- Prepare Sweet Potatoes: Peel and thinly slice the sweet potatoes. Aim for uniform slices to ensure even cooking.
- Make Cheese Sauce:
- In a saucepan over medium heat, melt the butter.
- Add minced garlic and sauté until fragrant (about 1 minute).
- Pour in the heavy cream, and stir in the thyme, salt, pepper, and nutmeg if using.
- Gradually add 1 1/2 cups of shredded cheese to the cream mixture, stirring until the cheese melts and the sauce becomes smooth.
- Assemble the Gratin:
- In a greased baking dish, arrange a layer of sweet potato slices.
- Pour a portion of the cheese sauce over the potatoes.
- Repeat the layers until all the sweet potatoes and sauce are used, ending with a layer of sauce on top.
- Top and Bake:
- Sprinkle the remaining 1/2 cup of cheese evenly over the top layer.
- Cover with aluminum foil and bake for 30 minutes.
- Remove the foil and bake for an additional 15-20 minutes, or until the top is golden and bubbly and the potatoes are tender.
- Let It Rest: Allow the gratin to rest for about 10 minutes before serving. This helps the layers set and makes serving easier.
Notes
- Even Slicing: Use a mandoline slicer to get even thin slices, which helps the potatoes cook uniformly.
- Cheese Variation: Feel free to mix cheeses for different flavors – Parmesan or mozzarella can be good additions.
- Herbs & Spices: Customize with other herbs like rosemary or spices like paprika for added depth.
