Key Ingredients For Sweet Potato & Cranberry Gratin – Easy Holiday Side Dish

Here’s what you’ll need to make this delicious dish:

  • Sweet Potatoes: Choose firm, vibrant sweet potatoes for optimal flavor; they should be free from blemishes.
  • Cranberries: Use fresh cranberries for a burst of tartness; avoid dried ones to maintain moisture in the dish.
  • Heavy Cream: Full-fat heavy cream adds richness and creaminess; you can substitute with half-and-half if preferred.
  • Butter: Unsalted butter is ideal to control salt levels; use it for both greasing the baking dish and adding flavor.
  • Cheese: Gruyère or sharp cheddar cheese works well for a flavorful topping; shred it fresh for best melting results.

For the Topping:

  • Bread Crumbs: Use panko breadcrumbs for extra crunch; they toast up beautifully when baked.
  • Fresh Herbs: Thyme or rosemary adds an aromatic touch; chop finely to distribute evenly throughout the gratin.

Instructions For Sweet Potato & Cranberry Gratin – Easy Holiday Side Dish

Follow these simple steps to prepare this delicious dish:

First Step: Preheat and Prepare

Preheat your oven to 375°F (190°C). Grease a medium-sized baking dish with butter to prevent sticking. This step ensures your gratin will bake evenly and achieve that perfect golden crust.

Second Step: Slice Sweet Potatoes

Peel and thinly slice sweet potatoes into uniform rounds about a quarter-inch thick. A mandoline slicer can help achieve even slices quickly. This consistency allows them to cook evenly during baking.

Third Step: Layer Ingredients

Arrange half of the sliced sweet potatoes in an overlapping layer at the bottom of your greased baking dish. Sprinkle half of the fresh cranberries over them. Repeat with another layer using remaining sweet potatoes and cranberries.

Fourth Step: Mix Cream Mixture

In a bowl, whisk together heavy cream, melted butter, salt, pepper, and a pinch of nutmeg until combined. Pour this mixture evenly over your layered sweet potatoes and cranberries to create a creamy base.

Fifth Step: Add Cheese and Topping

Sprinkle shredded cheese generously over the top layer. In a separate bowl, mix bread crumbs with chopped herbs and sprinkle this mixture over the cheese layer. This combination will give your gratin that enticing crunch.

Sixth Step: Bake

Cover your baking dish with aluminum foil and bake in preheated oven for about 45 minutes. Remove foil during the last 15 minutes to allow the top to brown nicely. Once it’s bubbly and golden brown on top, remove from oven.

Transfer to plates and serve warm as a perfect complement to your holiday feast!
