How to Make Sweet Potato Cranberry Gratin
Prep Your Ingredients: Start by preheating your oven to 375°F (190°C). Peel and slice sweet potatoes into uniform rounds for even cooking.
Prepare Your Dish: Grease a baking dish generously with butter. This ensures nothing sticks to your precious gratin during baking.
Create Your Cream Mixture: In a bowl, whisk together heavy cream, brown sugar, nutmeg, salt, and pepper until well combined. The mixture should be smooth and fragrant.
Add Layers of Flavor: Arrange half of the sweet potato slices in the baking dish. Pour half of your cream mixture over them before adding half of the cranberries.
Repeat Layering Process: Add another layer with remaining sweet potato slices followed by more cream mixture and cranberries on top. This builds flavor throughout.
Add Topping & Bake!: Sprinkle toasted breadcrumbs over the top layer for crunch. Bake uncovered in your preheated oven for 45-50 minutes until golden brown and bubbly.
Now you’re ready to indulge in this heavenly Sweet Potato Cranberry Gratin! Enjoy every bite as it warms your heart and soul.
