How to Make Cheesy Sweet Potato Gratin Recipe

Step 1: Prepare Oven and Baking Dish

Preheat the oven to 375°F (190°C) and generously butter a 2-quart casserole or gratin dish with 1 tablespoon of unsalted butter.

Step 2: Infuse Dairy with Herbs

Melt remaining 2 tablespoons unsalted butter in a small saucepan over medium heat. Add chopped garlic and cook for 30 seconds. Then, add chopped thyme, sage, 1/2 teaspoon kosher salt, heavy cream, whole milk, ground cinnamon, and nutmeg. Simmer gently, stirring occasionally, until slightly thickened for about 5 minutes. Remove from heat.

Step 3: Temper Eggs and Combine Mixtures

In a medium bowl, beat the eggs. Gradually whisk in 1 cup of the hot cream mixture to temper. Return to the saucepan, whisk until combined. Stir in 1/2 cup Parmesan cheese and season with black pepper.

Step 4: Layer Sweet Potatoes

Layer sweet potato slices in the dish, overlapping slightly, and season with kosher salt. Sprinkle with 2/3 cup shredded Gruyère cheese, then pour 2/3 cup of the cream-egg mixture over. Repeat layering process three more times, ending with cream mixture.

Step 5: Top and Prep for Baking

Evenly sprinkle the remaining 1/4 cup of Parmesan cheese on top. Cover the dish tightly with foil, ensuring the buttered side is facing down.

Step 6: Bake Covered and Uncovered

Bake covered for 30 minutes, then uncover and bake for an additional 30 minutes until bubbly, golden brown, and potatoes are tender.

Step 7: Finish and Serve

Take out of the oven and let it sit for a moment. Sprinkle with extra fresh thyme leaves and serve while warm.

Storage Tips

Once you have prepared and enjoyed the delicious sweet potato gratin, you can store any leftovers in the fridge for up to four days. Simply cover the dish tightly to maintain its creamy texture and flavor. To reheat, gently warm the gratin covered in a low oven to preserve its deliciousness.

If you want to freeze the gratin, ensure it cools completely before wrapping it well. Thaw it overnight in the refrigerator before reheating it uncovered to crisp up the top. This method of storage and reheating helps maintain the gratin’s quality and taste even after freezing. Feel free to experiment with different cheese options and herb combinations to create your unique twist on this gratin dish!

Ingredient Substitutions

If you don’t have Gruyère cheese on hand, Swiss or Emmental can be used as a delicious substitute that will provide a similar melt and taste. Fontina is another cheese that works well in this gratin. These cheeses will still bring a rich and creamy texture to the dish.

In case you run out of fresh thyme and sage, dried versions can be used as a replacement. Just remember to adjust the amount as dried herbs are more potent than fresh ones. Additionally, if you prefer a saltier touch, you can swap Parmesan cheese for pecorino. These substitutions will still ensure a flavorful and aromatic gratin that will impress your guests.

For a twist on the recipe, you can experiment with different herb combinations or seasonal additions. Try using rosemary instead of sage, adding thinly sliced apples for an autumn version, or incorporating a splash of orange zest during winter holidays. These variations will bring new flavors and aromas to the gratin, making it a versatile dish that can be enjoyed year-round.

Serving Suggestions

For a creative serving suggestion, try layering the sweet potato gratin in individual mini cast-iron skillets or ramekins for a personalized touch at your next dinner party. The individual servings make for a charming presentation and allow guests to enjoy their own perfectly portioned gratin.

Another idea is to top the sweet potato gratin with a sprinkle of crushed walnuts before serving. The addition of the crunchy nuts adds a delightful texture contrast to the creamy and cheesy layers, creating a more dynamic mouthfeel and enhancing the overall experience of this comforting dish.
