If you like potato casseroles, you’ll love our Vegan Jansson’s Temptation. You may or may not know what Jansson’s Temptation or Swedish “Janssons Frestelse” is but if you are Swedish or have ever lived in Sweden, you know that this dish is a classic on the Swedish Christmas dinner table. Although it can easily be eaten at any time of year. This dish is pure comfort food bliss! Janssons Frestelse is a creamy potato and anchovy casserole, and our vegan recipe uses jackfruit flavoured with wakame seaweed to substitute the anchovies.

Said to have been named after Pelle Janzon, a food-loving Swedish opera singer of the early 1900s. Since the 1940s when the recipe was published, it has become a classic Swedish favourite. Our vegan version appears on our Christmas table every single year. Enjoy!

So creamy and rich, you’re going to love this dish! Try it, it’s easy to make and very satisfying!
