The lightly caramelized sweet onions combine wonderfully with the fragrant thyme and creamy pastry. A hot entree, particularly tasteful and just four ingredients.
This onion tart with thyme shines in its simplicity and is delicious. The onion is caramelized and became sweet. The thyme smells great and gives its own flavor. The crispy, yet creamy puff combines wonderfully with these two. And what is especially nice, this dish is simple and easy to prepare. Two things that are very nice when you make an elegant Christmas dinner.
Because...
- onions become bitter when they burn, and you certainly do not want that to happen in this dish, caramelise them on low heat for a long time (about 15 minutes).
- Using a cookie cutter, you can make fun shapes out of the pastry that fit excellent with the Christmas theme. I used a cutter of Santa's boots.
- this dish has just four ingredients, so it's important that you use good butter puff pastry. Do not compromise on here! If you have any leftover pastry, make delicious cheese sticks!
