In winter in Germany, you often get to buy leeks in 1 kg bundles. It was cheap, but I only needed one leek for a stir-fry. Every time I opened the fridge I was wondering: "What the hell should I do with all those leeks?!?" Then I remembered the Swiss cheesecake my mom used to make - it has tons of onions in it and I thought I should try and substitute the onions with leeks. It was a full success!
Though I really liked the dense leek flavor, but somehow missed the sweetness of the onions. I guess I will make it 50/50 the next time.
By the way, this is NOT suitable for people trying to loose weight! There's tons of cheese, eggs and bacon... On the other hand, it's quite low on carbs, if that is your thing.
The cake is easiest to cut on the next day (like any cheesecake), but I like it piping hot and straight from the oven.
