Recipe Information
Ingredients
- 2 pounds Sweet potatoes
- 1.5 cups Heavy cream
- 0.5 cups Milk
- 3 cloves Garlic
- 2 teaspoons Fresh thyme
- 1 teaspoon Salt
- 0.5 teaspoons Black pepper
- 1 teaspoon Smoked paprika
- 0.5 teaspoons Red chili flakes
- 4 ounces Mild green chiles (roasted and diced)
- 1 cup Gruyere cheese (shredded)
- 0.5 cups Parmesan cheese (grated)
- 1 tablespoon Unsalted butter (for greasing)
Instructions
Preheat your oven to 375°F (190°C).
Grease a medium-sized casserole dish with the unsalted butter and set it aside.
Peel the sweet potatoes and slice them into thin, uniform rounds (approximately 1/4-inch thick) using a sharp knife or mandoline slicer.
In a medium saucepan, combine the heavy cream, milk, minced garlic, fresh thyme, salt, black pepper, and smoked paprika. Heat over medium-low heat until the mixture is warmed through and infused, about 5 minutes. Do not boil. Remove from heat.
Spread a single layer of sweet potato slices on the bottom of the prepared casserole dish, slightly overlapping the slices.
Sprinkle a small amount of the diced green chiles over the sweet potatoes.
Pour a few spoonfuls of the cream mixture over the layer, ensuring the potatoes are lightly coated.
Repeat the layering process (sweet potatoes, green chiles, cream mixture) until all the ingredients are used, finishing with a layer of cream on top.
Cover the casserole with aluminum foil and bake in the preheated oven for 40 minutes.
Remove the foil and sprinkle the shredded Gruyere and grated Parmesan evenly over the top.
Return the casserole to the oven, uncovered, and bake for an additional 20 minutes, or until the cheese is golden and bubbly and the sweet potatoes are tender when pierced with a fork.
Let the gratin rest for 10 minutes before serving. Garnish with additional thyme if desired.
