I’m not afraid to admit it–I’m an onion girl. The more the better.
And the only thing better than regular onions? Caramelized onions. Oh yum.
Which is why this super simple and easy-to-make five ingredient flatbread is so stinkin’ delicious–it’s caramelized onion perfection. Oh sure, you can fancy it up with a little rosemary and feta if you want to, but the humble onion is the main attraction. The star of the show.
And perfect for onion girls like me.

Giving it more stars than mine tastes due to my own mistakes. I used homemade dough from the bread machine. Too much, therefore can’t technically call it flat bread. Should have used 1/2 the dough. My onions started to blacken in the oven before the timer went off. Cut salt in half- Way too salty. Sea Salt would work just fine reducing the saltiness as well.
I’ll admit it too – I love onions! Caramelized sweet onions are my favorite! We put them on burgers, steaks and lots of apps, but I don’t think we’ve ever made caramelized flat bread. Bread and onions – sounds perfect to me! Thanks!
I would use a clump of homemade no knead bread dough instead, much cheaper, tasty and without any additives. Flour, salt, yeast, water, that’s all. You can keep it stored in the fridge in a container for more than a week, so no reason to buy dough anymore. Just google artisan bread in five, back to basics, or jim laheys no knead bread the nytimes recipe. It is dirt cheap also, talking about spending less.
Yuuummmm, I love caramelised onion too! I make my own pizza dough and this would be awesome for a grown up pizza… I doubt I could get my little ones to eat this – but all the more for me!
Oh, my gosh, that looks DELICIOUS!! I’m a bit of an onion girl, too, but my husband doesn’t eat them so I rarely cook with them. {sigh} Could you mail me any leftovers? Ha! I didn’t think so!
(Still, I think I’ll print this out for family gatherings, when I get to make things with onions to please the masses.)
