What You’ll Need

Here’s what you’ll need to make this delicious Sweet Potato Cranberry Gratin:
- Sweet Potatoes: Choose medium-sized sweet potatoes; they should be firm and without blemishes for the best flavor.
- Fresh Cranberries: Opt for bright red cranberries that are firm and plump; they add a lovely tartness to balance the sweetness.
- Heavy Cream: Full-fat cream gives this gratin its luxurious texture; you can substitute with half-and-half if desired.
- Butter: Unsalted butter enhances flavor without adding extra salt; it helps achieve a golden crust when baked.
- Brown Sugar: Use light brown sugar for sweetness; it complements the savory notes beautifully.

## Cooking Instructions
Follow these simple steps to prepare this delicious Sweet Potato Cranberry Gratin:
Step 1: Preheat Your Oven
Preheat your oven to 375°F (190°C). While it warms up, grab a baking dish (9×13 inches works well) and give it a light spray with nonstick cooking spray. You want this dish to slide right out when it’s done!
Step 2: Prepare Your Sweet Potatoes
Peel and slice your sweet potatoes into thin rounds—about 1/8 inch thick. The thinner they are, the better they’ll cook through. Try not to snack on too many slices; we need them for the gratin!
Step 3: Layer Up!
Start layering in your prepared baking dish by placing half of the sweet potato slices at the bottom. Sprinkle half of your fresh cranberries on top of those beauties. Repeat with another layer of sweet potatoes and cranberries.
Step 4: Mix Your Creamy Goodness
In a mixing bowl, whisk together heavy cream, melted butter, brown sugar, and thyme until well combined. Pour this luscious mixture evenly over your layered sweet potatoes and cranberries.
Step 5: Get Crunchy
In another bowl, mix panko breadcrumbs with a bit of melted butter (and Parmesan if you’re feeling fancy). Spread this crunchy topping evenly over your gratin – because who doesn’t love some extra crunch?
Step 6: Bake It!
Cover your baking dish with aluminum foil and pop it in the oven for about 30 minutes. After that time passes, remove the foil and bake for an additional 20-25 minutes until bubbly and golden brown.
Once it’s out of the oven and resting (if you can resist diving right in), serve it alongside roast turkey or as a delightful vegetarian main course. Trust me; everyone will be asking how you pulled off such magic in their plates!
