Kale & Sweet Potato Gratin - cooking recipe

Ingredients

5 tablespoons butter
3 garlic cloves, minced
kosher salt
fresh ground black pepper, to taste
1 bunch kale, stemmed and roughly chopped
2 1/2 lbs sweet potatoes, peeled and sliced about 1/8-inch thick
2 cups half-and-half
2 teaspoons ground cinnamon
1/2 teaspoon ground nutmeg
1 cup white cheddar cheese or 1 cup sharp cheddar cheese, grated

Preparation

Preheat the over to 400\u00b0F Rub the inside of a 8\"x8\" baking dish with 1 tablespoon of the butter.
Combine garlic, kale, potatoes, half-and-half, cinnamon, nutmeg and remaining 4 tablespoons butter in a pot; stir. Season with salt and pepper and taste the creamy liquid-it should be seasoned generously. Bring to a boil over medium-high heat while stirring the mixture. After 8-10 minutes the potatoes will be a little tender, and their starch will have thickened the liquid considerably.
Transfer the mixture to the prepared dish; smooth the top as much as possible. Cover the gratin with cheddar and bake until deeply golden brown, about 20-30 minutes. Let gratin cool and set a little before serving.
