This is a baked pork mince and potato casserole loosely based on the Swedish classic Jansson’s Temptation — layers of thinly sliced waxy potatoes, browned seasoned pork, and a cream-and-milk custard that sets into something genuinely satisfying. It takes about 20 minutes of hands-on work, feeds four, and reheats well all week.
What makes this version work
Two things matter here. First, browning the pork mince properly before it goes into the dish — not just until it loses its pink color, but until it has some real color on it. That’s where the flavor comes from, and it also drives off excess moisture that would otherwise make the casserole watery. Second, the cream-to-milk ratio (equal parts, 300ml each) keeps the custard rich without being heavy. Pour it in slowly so it seeps down through the layers rather than pooling on top. Those two steps are the difference between a soggy bake and a cohesive one.
Common problems and fixes
- Potatoes still firm after baking: Slice them thinner — aim for 3mm, not 5mm. Thicker slices need significantly longer cook time. A mandoline makes this consistent and fast.
- Custard hasn’t set and looks soupy when you cut in: The foil came off too early, or the dish was overcrowded. Let it rest 10 minutes out of the oven before cutting — the custard firms up as it cools slightly.
- Pork mince is dry and grainy in the finished dish: It was overcooked in the pan before layering. Pull it off the heat as soon as it’s browned through and reaches 160°F (71°C) — it will continue cooking in the oven.
- Breadcrumb topping is pale and soft: Your oven runs cool, or the foil was left on too long. If the top isn’t golden after 15 minutes uncovered, switch to the broiler for 2–3 minutes and watch it closely.
- Liquid boils over in the oven: The baking dish was too shallow. Use a dish with at least 2-inch sides, and don’t fill the custard above the top potato layer.
Ingredient notes
- Potatoes: Yukon Gold is the right call — waxy enough to hold their shape through a long bake without turning to mush. Russets will break down and make the layers indistinct. Don’t substitute.
- Heavy cream: Don’t swap for half-and-half. The fat content is what allows the custard to set rather than stay liquid. If you want to lighten it slightly, reduce the cream to 200ml and increase milk to 400ml — but expect a thinner result.
- Breadcrumbs: Plain dried breadcrumbs work fine. Skip the garnish of fresh parsley — not worth the extra dish when you’re portioning this out for the week.
Leftovers and meal prep
This casserole is genuinely better the next day once the custard has fully set and the flavors have had time to settle. Store leftovers covered in the fridge for up to 4 days. Reheat individual portions in the microwave at medium power for 2–3 minutes, or return the whole dish to a 160°C (320°F) oven covered with foil for 20 minutes. It also freezes well — portion it into individual containers before freezing and use within 2 months. Thaw overnight in the fridge before reheating; don’t try to reheat from frozen or the potato texture suffers. A single batch gives you four solid weeknight dinners with zero additional cooking.
Pork Mince and Potato Janssons Temptation
Ingredients
Ingredients
500 grams ground pork (minced pork) - Preferably organic or sustainably sourced
1 kg potatoes - Waxy variety like Yukon Gold, peeled and thinly sliced
2 medium yellow onion - Finely sliced
2 tablespoons butter - Unsalted
300 ml heavy cream - Freshly sourced
300 ml milk - Whole milk for richness
1 teaspoon salt - Adjust as needed
1 teaspoon ground black pepper - Freshly ground
2 tablespoons breadcrumbs - For a crispier topping
Instructions
- Preheat your oven to 180°C (356°F).
- In a large frying pan, melt the butter over medium heat, and sauté the onions until they become golden and translucent, about 5-7 minutes.
- Add the pork mince to the onions, breaking it up with a wooden spoon, and cook until browned, approximately 10 minutes. Season with salt and pepper.
- In a large baking dish, layer half of the sliced potatoes at the bottom. Top with half the mince mixture. Repeat the layers with the remaining potatoes and mince.
- Mix the heavy cream and milk in a bowl, pour over the layers until it just covers the top layer.
- Sprinkle the breadcrumbs over the top for an additional crunch.
- Cover the dish with foil and bake in the preheated oven for 45 minutes. Remove the foil and bake for an additional 15 minutes or until the top is golden and the potatoes are fork-tender.

Common questions
Can I use regular ground pork from the supermarket, or does it need to be a specific fat percentage?
Regular supermarket ground pork works fine. A fat percentage around 15–20% gives the best result — leaner than that and the mince can turn dry during the long bake. Avoid extra-lean ground pork for this recipe.
How do I know the pork is fully cooked and safe to eat?
Ground pork must reach an internal temperature of 160°F (71°C) — use an instant-read thermometer to check the mince layer in the center of the dish. After 45 minutes covered plus 15 minutes uncovered at 180°C, it will be well past that temperature, but checking is always worth it.
Do I need to peel the potatoes?
Yes, peel them. The skin on Yukon Golds is thin but it creates a slightly tough texture in the layers that doesn’t soften the same way the flesh does. Peeling takes two minutes and the result is noticeably smoother.
Can I assemble this the night before and bake it the next day?
Yes, and it’s a good strategy. Assemble the layers, pour over the cream and milk, cover tightly with foil, and refrigerate overnight. Add the breadcrumbs just before it goes into the oven — if you add them the night before they absorb moisture and won’t crisp up.
Can I double the recipe to make a larger batch?
You can, but use two separate baking dishes rather than one very deep dish. A single oversized dish won’t cook evenly — the center will still be underdone when the edges are ready. Two standard dishes at the same oven temperature and timing works reliably.
What can I serve alongside this to make it a complete meal?
A simple green salad or steamed green beans cuts through the richness well. Because the casserole already contains potato and protein, you don’t need a starch on the side — keep it light so the portions reheat well through the week without feeling heavy.
