I'm a big fan of lasagna, especially al forno. However most italian restaurants in korea offer only koreanised, so called 'oven spagetthi', which are eatable but nothing more.
You might understand how surprised i was when i found this instant Lasagna al Forno at Homeplus:
For around 5000 won you get 280g lasagna and an obscene amount of calories ^^. My expectations were not high because mostly pre made stuff is only convenient but not authentic. However this one blew me away. Good strong tomato sauce, much cheese which might even be mozzarella, al dente pasta plates in the middle and lo and behold: béchamel sauce under the cheese. Especially the Béchamel under the cheese was very unexpected (until now i only found one restaurant in seoul making their lasagna properly with béchamel).
In clonclusion i can say this one is well worth its price. Less then 300g doesn't sound like much but its very heavy and therefore enough for one person. The overall taste is very nice but of course not as good as a good fresh lasagna. However compared to the common oven spaghetti this dish is clearly better.
Try it out :)
