Step-by-Step

Time to bring this divine Sweet Potato Gratin to life! Follow these simple steps to create your masterpiece.

Preheat the oven to 375 degrees F. Butter a 2-quart casserole or gratin dish with 1 tablespoon of butter.
In a small saucepan over medium heat, melt 2 tablespoons of butter. Once the butter stops foaming, add the chopped garlic and cook, stirring, until fragrant—about 30 seconds.
Toss in the fresh thyme, sage, and 1/2 teaspoon of salt and continue cooking, stirring occasionally, until heated through (around 30 seconds).
Now, add the cream, milk, cinnamon, and nutmeg. Bring this glorious mixture to a gentle simmer, stirring frequently for about 5 minutes, until slightly thickened. Remember, no boiling allowed!
Remove it from heat. In a medium bowl, beat the eggs. Transfer 1 cup of the cream mixture to a measuring cup or bowl equipped with a spout. While whisking constantly, slowly stream that cream mixture into the eggs a few tablespoons at a time until fully incorporated.
Add your egg mixture back into the saucepan with the remaining cream mixture and whisk until well combined. Stir in 1/2 cup of the grated Parmesan and season generously with freshly ground black pepper.
Layer the bottom of your prepared dish with a layer of sweet potato slices, slightly overlapping each one. Season this layer with a pinch of salt, then top with 2/3 cup of Gruyere cheese and 2/3 cup of cream mixture.
Repeat these layers three times, ending with the cream mixture on the top. Finish off with the remaining 1/4 cup of grated Parmesan.
To finish, butter a piece of foil and tightly cover the dish. Bake the gratin for 30 minutes, then remove the foil and continue baking until the sides are bubbling and golden brown, another 30 minutes approximately.
Finally, top your beautiful gratin with some extra fresh thyme before serving hot!

Visually stunning and packed with flavor, your Sweet Potato Gratin will be an irresistible treat!
