This Swedish Potato Casserole or Jansson's Frestelse (which means temptation!) is simplicity itself. Just potatoes, cream and onions with a little salty flavor from the added anchovies.
Recipe type: Main or side dish
Cuisine: Swedish
Serves: 4 as a main, 6-8 as a side
  • 1 medium onion, sliced thinly
  • 2 tablespoons butter, plus extra for topping
  • 2 lbs or 910g Idaho® potatoes
  • 1 can anchovies in oil, drained (drained weight 1¾ oz or 50g)
  • 1¾ cups or 414ml heavy whipping cream
  • Salt and freshly ground black pepper
  • ¾ cup or 45g fresh breadcrumbs
  • butter
  1. Preheat your oven to 350°F or 180°C.
  2. Peel and slice the onions thinly. Sauté them gently in a pan with the butter, until they are soft. Do not let them brown.
  3. Grease the bottom and sides of your baking dish or dishes, using a pastry brush dipped into the oil you drained off of the anchovies.
  4. Peel the potatoes and cut them into strips. Use one third of the potatoes to line the bottom your greased baking dish/es.
  5. Add half of the sautéed onions and half of the drained anchovies. Top with another third of the potatoes, then the remaining onions and anchovies.
  6. Finish with the balance of the potatoes. Sprinkle with some salt and a few good grinds of black pepper. Pour in the cream.
  7. Sprinkle the top with the fresh breadcrumbs and put a few little slices of butter on them.
  8. In case the Swedish creamy potato casserole bubbles over, I suggest using a baking pan or some heavy duty foil under the casserole dish/es. Bake for about 45 minutes for smaller casserole dishes and as much as an hour for one big one, or until the potatoes are tender. You can cover them with some foil if they are browning fast but the potatoes aren’t cooked through yet.
  9. When the casserole is done, remove it from the oven and leave to cool for about 10 minutes before serving.
