This classic Swedish comfort food, Jansson’s Temptation, is a rich and indulgent casserole that layers thinly sliced potatoes with caramelized onions and salty anchovy fillets. The dish is soaked in a luxurious mixture of heavy cream and milk, then baked until the potatoes are tender and the top is golden brown. Despite the strong flavor of the anchovies, they melt into the sauce, providing a subtle umami depth rather than a fishy taste. It is the perfect hearty side dish or vegetarian-friendly main (if you omit the anchovies) for holiday gatherings or cozy winter dinners. The creamy texture and savory aroma make it an irresistible crowd-pleaser.

Directions
-
Preheat the oven to 400&# 194;°F (200ðC).
-
Peel the potatoes and cut them into thin strips, approximately 2 inches long and 1/4 inch wide.
-
Place the cut potato strips in a bowl of cold water to prevent discoloration while you prepare the other ingredients.
-
In a 10-12 inch skillet, melt 2.5 tablespoons of butter with 2 tablespoons of vegetable oil over medium heat.
-
Add thinly sliced yellow onions to the skillet once the butter foam subsides.
-
Cook the onions for about 10 minutes, stirring frequently, until they are soft and translucent but not brown.
-
Lightly grease a 1.5 to 2-quart soufflé dish or baking casserole with the remaining half tablespoon of butter.
-
Drain the potatoes thoroughly and pat them dry with paper towels.
-
Arrange a layer of potato strips on the bottom of the prepared baking dish.
-
Top the potatoes with a layer of the cooked onions.
-
Add a layer of drained flat anchovy fillets over the onions.
-
Sprinkle a little white pepper over the layer.
-
Repeat the layering of potatoes, onions, and anchovies, alternating until all ingredients are used, ending with a layer of potatoes on top.
-
Scatter fine dry bread crumbs evenly over the top layer of potatoes.
-
Dot the casserole with 2 tablespoons of butter cut into small bits.
-
In a small saucepan, heat heavy cream and milk together until they just begin to simmer.
-
Pour the hot cream mixture evenly over the layered potatoes in the baking dish.
-
Bake in the center of the oven for 45 minutes, or until the potatoes are tender when pierced with a sharp knife and the liquid is nearly absorbed.

Note
Anchovy fillets are traditional in Jansson's Frestelse. They dissolve into the sauce during baking, adding a savory depth without an overpowering fish taste. If you prefer a vegetarian version, you can omit the anchovies entirely or substitute them with a small amount of white miso paste mixed into the cream for similar umami richness.
Ensure the potatoes are thinly sliced for even cooking. If your potatoes are particularly large, consider slicing them even thinner to ensure they cook through in the allotted time.
The dish should be served immediately after baking while the crust is still crisp and the center is creamy. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated in the oven or microwave.
