Ingredients
Method
Preheat Oven:
- Heat oven to 375°F (190°C) and butter a 9×13 baking dish.
Heat Cream Mixture:
- In a saucepan over medium heat, melt butter. Add garlic and sauté 1 minute.
- Stir in cream, salt, pepper, paprika, and thyme. Heat until warm — don’t boil.
Layer Potatoes:
- Place a layer of sweet potatoes in the baking dish.
- Pour a little cream mixture over top and sprinkle with Parmesan (and Gruyère if using).
- Repeat layers until all potatoes are used.
Bake:
- Cover with foil and bake 35 minutes.
- Remove foil and bake 15–25 more minutes, until potatoes are tender and top is golden and bubbly.
Rest & Serve:
- Let cool 10 minutes before serving to help set the layers.
Notes
Use a mandoline slicer for even, thin slices.
Add a drizzle of maple syrup to the cream for a touch of sweetness.
For extra richness, caramelize onions and layer them in.
If top browns too fast, tent loosely with foil.
Swap Parmesan for goat cheese or feta for a tangy twist.
