A savory sweet-potato bake
Thin sweet-potato slices soften in warm garlic-sage dairy, with a little Parmesan coloring the top. It is a savory gratin rather than a brown-sugar or marshmallow casserole.
The cream level, eight portions and sixty-five-minute oven estimate are working assumptions until tested in the specified dish.
Slice evenly for an even bake
Peel and cut the sweet potatoes to approximately one-eighth inch. Thick mixed slices can leave some sections hard while others collapse.
A mandoline can help but requires its guard. Spread slices through the pan rather than building one very tall mound in the middle.
Ingredients for 8 side portions
| Ingredient | Amount | Use |
|---|---|---|
| Sweet potatoes, peeled | 2 1/2 pounds | Slice evenly about 1/8 inch thick. |
| Heavy cream | 1 1/2 cups | For sauce. |
| Whole milk | 1/2 cup | For sauce. |
| Garlic cloves, minced | 2 cloves | Infuse dairy. |
| Fresh sage, finely chopped | 2 tablespoons | Dairy and topping. |
| Fine salt | 1 teaspoon | Divide through layers. |
| Ground black pepper | 1/4 teaspoon | For sauce. |
| Parmesan cheese, finely grated | 1/2 cup | For top; check cheese label. |
| Unsalted butter | 1 tablespoon | For dish. |
Step-by-step method
- Heat oven to 375°F and grease a 9-by-13-inch baking dish with 1 tbsp butter. Slice 2 1/2 lb peeled sweet potatoes into even approximately 1/8-inch rounds.
- Warm 1 1/2 cups heavy cream and 1/2 cup whole milk with two minced garlic cloves, 2 tbsp chopped sage, 1 tsp salt and 1/4 tsp pepper just until steaming, not boiling.
- Layer the sweet-potato slices evenly in the dish, pour warm seasoned dairy over them and sprinkle 1/2 cup grated Parmesan on top. Cover tightly with foil and bake about 40 minutes.
- Uncover and bake another 20–25 minutes until a knife passes easily through the center and top is golden. Rest 15 minutes before cutting eight provisional side portions. Test dish depth and sauce absorption.
Warm the cream gently
Heating cream and milk with garlic and sage distributes seasoning before pouring. Do not boil aggressively or reduce the liquid to a much smaller volume.
The full teaspoon of salt is for the dish, not an extra topping measure; Parmesan brings additional saltiness.
Cover, then color
The covered interval steams slices in the dairy. Uncover for the final twenty to twenty-five minutes to color the top and let some liquid concentrate.
A knife should pass easily through the center. If the surface browns early but the middle resists, cover again and extend after documenting the trial.
Rest and serve
Fifteen minutes standing makes portions easier to lift. Serve as a side, not a main that includes eight full meals.
Refrigerate leftovers promptly. A precise freeze or reheat-quality recommendation is not established for this cream sauce.
Scalloped-potato questions
Are these regular white potatoes?
No. The card uses orange-fleshed sweet potatoes.
Is the dish sweetened?
No maple or sugar appears in the savory base.
Why rest before cutting?
The hot cream sauce can settle around the layers for neater portions.
