Southern Sweet Potato and Kale Gratin

Let’s make it

1. 1

   Preparation

   Preheat the oven to 190°C (375°F). Grease a 9x13-inch baking dish with butter or nonstick spray.

2. 2

   Sauté

   In a large skillet, heat olive oil over medium heat. Add diced onion and sauté until softened, about 5 minutes. Add minced garlic and cook for 1 more minute until fragrant.

3. 3

   Sauté

   Add chopped kale to the skillet and cook until wilted and tender, about 5-7 minutes. Season with salt and black pepper to taste. Remove from heat.

4. 4

   Sauce Preparation

   In a medium saucepan, melt butter over medium heat. Whisk in flour and cook for 1-2 minutes to form a roux, stirring constantly.

5. 5

   Sauce Preparation

   Gradually whisk in whole milk, continuing to stir until sauce thickens and is smooth, about 5 minutes. Remove from heat and stir in cream cheese, grated Gruyère cheese, ground nutmeg, salt, and black pepper to taste until fully combined and creamy.

6. 6

   Assembly

   Layer half of the sliced sweet potatoes in the prepared baking dish. Spread the sautéed kale and onion mixture evenly over the potatoes.

7. 7

   Assembly

   Add the remaining sweet potato slices over the kale layer. Pour the cheese sauce evenly over the top, ensuring it covers all layers.

8. 8

   Baking

   Cover the baking dish with foil and bake for 30 minutes. Remove the foil and bake another 10-15 minutes until the top is golden and bubbly, and the sweet potatoes are tender when pierced with a fork.
