• 1 cup heavy cream

How to Make Sweet Potato & Cranberry Gratin

Step 1 – Prep the Sweet Potatoes:
Preheat oven to 375°F (190°C). Grease a baking dish with butter. Arrange a layer of sweet potato slices along the bottom.

Step 2 – Create the Cream Mixture:
In a saucepan, melt butter over medium heat. Add garlic and thyme, cooking until fragrant (about 1 minute). Stir in the cream, salt, and pepper, heating until just warm.

Step 3 – Layer the Gratin:
Pour a bit of the cream mixture over the first layer of sweet potatoes. Add a sprinkle of cranberries, then repeat the layers until all ingredients are used. Finish with the remaining cream.

Step 4 – Add Topping:
Sprinkle parmesan and breadcrumbs (or pecans) on top for a golden, crispy crust.

Step 5 – Bake:
Cover with foil and bake for 30 minutes. Remove the foil and bake for another 15–20 minutes until the top is bubbly and golden brown.
