Recipe Information
Ingredients
- 2 large sweet potatoes
- 2 medium Ontario apples
- 1 cup heavy cream
- 0.5 cup milk
- 2 cloves garlic
- 1 teaspoon fresh thyme
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 1 cup gruyere cheese, shredded
- 1 tablespoon butter
- 0.25 cup panko breadcrumbs
Instructions
Preheat the oven to 375°F (190°C). Lightly grease a 9-inch baking dish with the butter.
Peel and slice the sweet potatoes and Ontario apples thinly (around 1/8-inch thick) using a sharp knife or mandoline slicer.
In a small saucepan, combine heavy cream, milk, minced garlic, fresh thyme, salt, and black pepper. Warm over low heat for 5 minutes, stirring occasionally, then remove from heat.
Layer half of the sweet potato slices in the bottom of the prepared baking dish, overlapping slightly. Follow with a layer of half the apple slices.
Pour half of the warmed cream mixture evenly over the layers. Sprinkle with half of the shredded Gruyere cheese.
Repeat the layers with the remaining sweet potatoes and apples. Pour the rest of the cream mixture on top and finish with the remaining Gruyere cheese.
In a small bowl, mix the panko breadcrumbs with a drizzle of melted butter (optional), then sprinkle the mixture evenly over the top of the gratin.
Cover the dish with foil and bake in the preheated oven for 30 minutes. Remove the foil and bake for an additional 20 minutes, or until the top is golden and the sweet potatoes and apples are tender when pierced with a knife.
Let the gratin rest for 5–10 minutes before serving. Enjoy this savory and sweet dish as a side or main course!
