Caramelized Onion Tart

It’s simply Yummilicious …

Caramelized Onion Tart!

Caramelized Onion Tart

I love this Caramelized Onion Tart! The flavors have that buttery and nutty gorgeous taste from caramelizing the onions first and then topping it off with olives – OH need I say more?!? Yum.

You can also pimp it up by adding some roasted garlic cloves scattered generously for an added burst of nutty flavor and if you like, top it off with some Feta or Goat’s cheese to make it irresistible.

Onion Tart

This is one of those recipes that include simple on hand ingredients. I try to keep the puff pastry sheets in freezer at all times. Puff Pastry is so versatile for both sweet and savory foods that makes it a must have. Also the oil cured black olives are some of my favorite olives … which come to think of it, actually makes it a bit harder to keep them in the pantry, but I do try. Onions … I go through so many onions weekly – a lot of onions – but they are always available to grab and use.

  1. Have you ever made the tart in the morning and reheated it later? Or under-baked it and finished it off later?
    I was thinking of making this with pizza dough. What do you think about making with this with the pizza dough and doing the same thing? Do you think the taste will suffer if served room temperature?

    1. Hi Elizabeth! I have reheated the tart before and made sure to do it in the oven to maintain the crispness of the crust. With a puff pastry it would be best to bake it all the way or the dough may not puff properly, so it would be best to bake all the way and then reheat in the oven. I think pizza dough would work beautifully, it would be more “bread like” than the puff pastry but would still taste great. Just so you know, I always ate any leftovers at room temperature and loved it, but then again I enjoy the likes of cold pizza too for a snack or even breakfast (don’t tell my kids that bit though, lol). Experiment and let me know how it worked out for you. I hope you enjoy! 🙂
