Creating the Best Scalloped Sweet Potatoes is straightforward when you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish.
2. Prepare Sweet Potatoes: Peel and thinly slice the sweet potatoes using a mandoline or a sharp knife.
3. Make the Cream Sauce: In a saucepan, melt the butter over medium heat. Add the minced garlic and sauté for 1 minute until fragrant.
4. Combine Cream and Spices: Stir in the heavy cream, salt, pepper, thyme, and paprika. Bring the mixture to a gentle simmer, then remove from heat.
5. Layer the Potatoes: Arrange half of the sweet potato slices in the prepared baking dish. Pour half of the cream sauce over the sweet potatoes.
6. Add Cheese: Sprinkle half of the cheddar and Gruyère cheeses over the first layer.
7. Repeat Layers: Add the second layer of sweet potato slices, followed by the remaining cream sauce and cheeses.
8. Top with Breadcrumbs: If desired, sprinkle breadcrumbs on top for added texture.
9. Bake: Cover the baking dish with aluminum foil and bake for 40 minutes. Remove the foil and bake for an additional 20 minutes, or until the sweet potatoes are tender and the top is golden brown.
10. Cool and Garnish: Once baked, let it cool for a few minutes before garnishing with fresh parsley.
