Caramelized Onion Thin Crust Pizza

This Caramelized Onion Thin Crust Pizza is another recipe where the flavour is exceptional considering there are just a few relatively humble ingredients.  It gets rave reviews every time I make it.

It can be a cinch to make because you can make a double batch of the Overnight No Knead Pizza Dough and the onions and freeze them (separately).

Overnight No Knead Pizza Dough

Then you can pull them out in the morning and assemble your pizzas in no time at all.

You can buy Garlic oil (or many other flavoured oils) but it is also simple to make. It lasts about a week in the fridge and you can use it in salad dressings, brush on vegetables for grilling, brush on pizza, crostinis, garlic bread.

The dough is very thin and crisps up nicely when cooked.  Sometimes my base has spots that are thinner than others.  I don’t worry about it…that piece will be a little bit crunchier but that can be nice too.  I cut them in squares  (or random smallish shapes) so they are easy for guests to handle with one hand. My friend made a brilliant suggestion when I was ready to serve them…. cut them with good kitchen scissors!  It is actually much easier than a pizza wheel on this crispy dough.

Chef’s Tip for Caramelized Onion Thin Crust Pizza

I often make caramelized onions ahead of time in my 1 quart slow cooker. Mix the regular olive oil, onion, thyme, brown sugar and red wine together and cook on low 6-8 hours. I make up batches and freeze some for onion soup, burger toppings, whatever you like!

Make a double batch of Overnight No Knead Pizza Dough so you freeze some dough and just thaw it as you need it.

Wine Pairing for Caramelized Onion Thin Crust Pizza

My goto for this would be a medium bodied Chardonnay mildly oaked. The sweetness of the onions would be a nice complement to that.

An mildly earthy red go well here as well, think Malbec or a Mourvedre blend.

Add onion slices, brown sugar and thyme to the skillet and reduce heat to med-low.Saute, stirring often at least 20 minutes, til onions are a rich golden colour. Be careful not to burn the onions.
