Instructions for our Sweet Potato Gratin Recipe Perfect For Thanksgiving Dinner
Preheat the oven to 400° Fahrenheit. Stir together the cream, sage, nutmeg, onion, garlic, salt and pepper and heat in a pan on a medium heat for five minutes. Keep it just below boiling point if you can.
Lightly butter a 9 x 13-inch casserole dish with the butter. Spoon out one quarter of the cream and onion mixture, then layer one third of the sweet potatoes on top. Cover with another quarter of the cream and onion mixture.
Add another layer of potatoes, followed by cream, and then sprinkle on one third of the cheese. Finish off with a final layer of potatoes, cream and the rest of the cheese. Sprinkle on a little black pepper and cover the dish with aluminum foil.
Bake in the oven for 45 minutes, then take the aluminum foil off and cook for a further 15 minutes to allow the cheese to brown. Take out of the oven and sprinkle with a few sage leaves before serving.
