    Apple and Sweet Potato Gratin
  • 3 lbs sweet potatoes, peeled and sliced in 1/4-inch (5 mm) thick round 1.5 kgs
  • 1 onion, thinly sliced 1
  • 4 Ontario apples, peeled, cored and sliced in 1/4-inch (5 mm) thick rounds 4
  • 1 cup milk 250 mL
  • 1 tbsp all-purpose flour 15 mL
  • 1/2 tsp dry mustard 2 mL
  • 1/2 tsp each salt and pepper 2 mL
  • 1 cup shredded Gruyère cheese 250 mL


Arrange half of the sliced sweet potatoes over the bottom of an 8-inch round or square (2 L) baking dish. Arrange half of the sliced onions over the sweet potatoes and half of the sliced apples over the onions. Repeat these layers with remaining ingredients.

Preheat oven to 400 F (200 C). In medium bowl, whisk together milk, flour, mustard, salt and pepper. Drizzle over apples. Sprinkle with cheese.

Cover with foil and bake in preheated oven for 45 minutes. Remove foil and bake until cheese is bubbly and golden and potatoes and apples are tender, approximately 15 minutes. Let stand 10 minutes before serving.
