Ingredient Notes & Details
Sweet potatoes
Choose firm, evenly sized sweet potatoes for uniform slices.
Orange-fleshed varieties offer the best sweetness and creamy texture.
Garlic
Fresh garlic is essential here. Thinly sliced or minced garlic infuses the cream as it bakes.
Avoid garlic powder for this recipe—it won’t deliver the same depth.
Heavy cream
Creates that classic scalloped potato richness.
Half-and-half works as a lighter option with slightly less creaminess.
Butter
Adds richness and helps prevent sticking.
Unsalted butter lets you control the seasoning.
Cheese (optional)
Gruyère, Parmesan, or sharp white cheddar all work beautifully.
Adds a savory contrast to the sweet potatoes.
Salt and black pepper
Essential for balancing the natural sweetness.
Season every layer lightly for best flavor.
Fresh thyme or rosemary (optional)
Adds a subtle herbal note that pairs perfectly with garlic and sweet potatoes.
Use sparingly so it doesn’t overpower.
Step-by-Step Instructions
Preheat and prepare the baking dish
Preheat your oven to 375°F (190°C).
Butter a baking dish generously to prevent sticking and enhance flavor.
Slice the sweet potatoes evenly
Peel the sweet potatoes and slice them into thin, even rounds—about ⅛-inch thick.
Uniform slices ensure even baking and tender layers.
Prepare the garlic cream
In a saucepan over low heat, warm the cream with butter, garlic, salt, and pepper.
Do not boil—just gently heat to infuse the garlic flavor.
Layer the sweet potatoes
Arrange a layer of sweet potato slices in the baking dish, slightly overlapping.
Lightly season and spoon some garlic cream over the top.
Add cheese and repeat
Sprinkle a small amount of cheese over the layer if using.
Repeat layering until all ingredients are used.
Cover and bake
Cover the dish with foil and bake for 40–45 minutes.
This allows the sweet potatoes to soften without browning too quickly.
Uncover and finish baking
Remove foil and bake another 20–25 minutes until golden and bubbly.
The top should be lightly browned and fork-tender throughout.
Rest before serving
Let the dish rest for 10 minutes before serving.
This helps the sauce thicken and layers set.
