Caramelized Onion and Apple Waffles

These caramelized onion and apple waffles are slightly sweet from caramelized onions and grated apple. And they have that perfect waffle texture – soft on the inside and crisp on the outside.

They’re quick and easy to make if you have leftover caramelized onions. If not, take an extra moment to cook up a batch for the next time you want waffles.

You can serve these for breakfast smothered in maple syrup. But they’re a great twist as a “bread” for sandwiches or to dip into a hearty fall soup or stew.

Key technique: caramelizing onions

Caramelizing onions is not hard. It only requires patience.

Patience is a virtue. Right?

The key is the perfect caramelization is slow cooking so the water in the onion evaporates and the natural sugars start to caramelize. This can take about an hour. Sometimes more and sometimes less.

Use a pan as large you have to avoid steaming the onions. And stir occasionally to minimize sticking.

Additional sugar isn’t needed for caramelized onions, but you’ll want to add salt about 20 to 30 minutes in to help the evaporation process. And don’t forget to add a bit of water at the end to scrape up any brown bits that have stuck to your pan.

FAQs

Do I need to weigh my ingredients for this recipe?

You’ll get more reliable results if you weigh your ingredients. But you never have to do anything.

Will this make my waffle iron smell like onions?

I make savory waffles all the time and simply wipe down the waffle plates after each use. I’ve never had the smell or flavor of savory waffle stick around.

What waffle iron do you use?

We’ve got the Cuisinart Classic and an All-Clad Stainless Steel Classic. To be honest, the simple Cuisinart does the job equally well for much less money.

Can I freeze extra waffles?

Yes, waffles freeze perfectly in a freezer bag for three to six months. Just pop one in the toaster whenever you want an apple waffle.
