This Red Wine Caramelized Onion Flatbread recipe has a beautifully balanced flavor profile and is easier to make than you might think. It’s the perfect little bite to nibble on!
One of the best things about summer is taking the time to just enjoy.
Enjoy the company of friends and family, enjoy being outdoors, and enjoy good food and drink.
Back home in Buffalo, one of my favorite summer activities is spending an evening at Shakespeare in Delaware Park.
It’s an outdoor theatre experience that’s very unique to the region. Basically, you watch a live play outside while sitting on the lawn in front of the theater. Not only is it enriching in a cultural sense, but it’s a beautiful way to make memories. I’m still looking for something like it here in the Orlando area; it was a truly special experience.
Find something fun in your area, pack a picnic (that’s where this Red Wine Caramelized Onion Flatbread comes in), grab a few friends, and head outside!

Variations on This Recipe
- Strawberries + goat cheese. Instead of Manchego + grapes, use chopped fresh strawberries and crumbled goat cheese.
- Blueberries + feta. Or go with fresh blueberries (each sliced in half) and crumbled feta.
- Fig + blue cheese. If you like the earthy sweetness of figs paired with the salty richness of blue cheese, this will probably become your new favorite combination. If you go this route, I would thinly slice or quarter the figs.
- Raspberries + brie. Next up on my list to try is the raspberry and brie pairing!

Caramelized Onion Flatbread FAQs
How Do You Caramelize Onions?
Caramelized onion adds a sweet richness to just about anything, like burgers, omelets, grilled chicken or steak, pasta, and of course, French onion soup!
And of course caramelized onion adds great depth of flavor to this easy flatbread recipe.
If you've never caramelized onion, you'll be surprised at how easy it is to do!
Steps to Caramelize Onion:
- Peel, halve, and thinly slice onion (I like to use yellow onion).
- Add a bit of butter to a skillet over medium heat (about one tablespoon for each medium-large onion).
- Once the butter melts, add the onion and a pinch of salt and pepper. To add another level of flavor to this recipe, I added a bit of red wine as well (it cooks off during the cooking process).
- Cook until the onions are caramelized, about 20 to 25 minutes, stirring occasionally. You can add a splash of water or turn the heat down slightly at any point if the onions start to get too dark or start to stick to the skillet.
- Use caramelized onion in just about anything/everything!
What's the Difference Between Flatbread and Pizza?
The main difference between pizza and flatbread is the type of dough used. Pizza is made with dough that's leavened with yeast. On the other hand, flatbread is made with non-yeasted dough.
Because of this, pizza generally has a chewier, thicker crust than flatbread.
What Type of Red Wine Should I Use For This?
To caramelize the onions for this flatbread recipe, you'll want to use a dry red wine.
Dry red wine is red wine that doesn't taste sweet. A few types of dry red wine include Merlot, Pinot Noir, and Cabernet Sauvignon.
