Instructions

  1. Heat the oven to 375 F. Butter a 2 L baking dish.
  2. Slice the potatoes about 3 mm thick. Use a mandoline if you have one, or a sharp knife and your finest imitation of patience.
  3. Melt the butter in a saucepan over medium heat. Add the onion and cook for 4–5 minutes, until softened but not browned.
  4. Add the garlic and cook for 30 seconds. Stir in the flour and cook for 1 minute, stirring constantly.
  5. Slowly whisk in the milk and cream. Add the salt, pepper, thyme and nutmeg, if using. Cook for 3–4 minutes, until the sauce thickens slightly.
  6. Arrange half the potatoes in the baking dish. Pour over half the sauce, then repeat with the remaining potatoes and sauce.
  7. Cover tightly with foil and bake for 45 minutes.
  8. Uncover, sprinkle with cheddar if using, and bake for 20–30 minutes more, until the potatoes are tender and the top is golden.
  9. Rest for 10–15 minutes before serving. Sprinkle with parsley or chives if using.

Cultural Context

Scalloped potatoes sit in that deliciously disputed corner of food history where several countries can reasonably raise a hand. In Canada, scalloped potatoes became less about culinary ownership and more about showing up beside ham, turkey or roast meat like a loyal sidekick with better manners.

Fun Fact

The word “scalloped” does not mean the dish contains scallops. A relief, usually.

Cook’s Tip

Yukon Gold potatoes hold their shape well and turn creamy without falling apart. Cheddar is optional; without cheese, the dish stays closer to classic scalloped potatoes.

Trivia

Cheese often appears in Canadian home versions, but classic scalloped potatoes can be cheese-free.
