Caramelized Onion and Thyme Flatbread 1

Caramelized Onion and Thyme Flatbread. Doesn’t the name alone just make your mouth water? This past weekend we celebrated the last day of school with a fun pizza and movie night. Little Buddy chose the pizza toppings and the movie, but I made a quick appetizer to munch on as our pizzas were coming together.

I already had plenty of pizza dough rising in bowls on my counter and onions caramelizing to add to the endless topping options I was preparing, so I decided to pull off a portion of the dough for this quick flatbread.

As I cut it into pieces we could easily hold in our hands as we meandered around chatting about what we wanted to do this summer, Little Buddy asked me this question,

“So, what’s the difference between flatbread and pizza anyway?”

At first I answered that although it uses pizza dough, it doesn’t include cheese which is the major difference. He replied that his friend Ben couldn’t eat cheese and ordered cheeseless pizzas all the time.

Then, I said that maybe it was because pizzas are usually round and flatbreads are not. He reminded me that my pizzas are rarely ever round and asked if that meant we had been eating flatbreads all this time.

It was a lot to consider. Had my pizza-making-life all been wrong? Was I really making flatbread all this time? Or, are flatbreads and pizzas really the same thing after all?

Here’s the recipe for my Caramelized Onion and Thyme Flatbread… errr… Pizza…. err… Flatbread.

Caramelized Onion and Thyme Flatbread makes a wonderful appetizer or side to a large salad.
Prep Time: 45 minutes
Cook Time: 15 minutes
Total Time: 1 hour
Servings: 12



  • Preheat oven to 425º F.
  • Prepare pizza dough according to recipe directions. Spread dough onto a baking pan lightly coated with olive oil. Make indentions into dough with finger tips and lightly drizzle crust with olive oil.
  • Drizzle olive oil into a large skillet over medium heat. Add onion slices and allow to cook until caramelized and tender, about 10 minutes. Watch onions closely so they do not overbrown. Arrange onions onto pizza dough and bake for 15-20 minutes until golden brown.
  • Remove from oven and immediately top with fresh thyme leaves that have been removed from the stem.
  • Sprinkle with salt and pepper, slice, and serve warm.


To reduce time, you can prepare pizza dough and store in an airtight container in the refrigerator for a few days until ready to use. Additionally, you could use prepared pizza dough purchased at your grocery store.

  6. Sylvie @ Gourmande in the Kitchen says:

    Good question! I’ve often wondered the difference between pizza and flatbread as well.

    1. Robyn Stone says:

      I’m a bit perplexed and the more I read, the more I can’t find an answer! So glad I’m not the only one that doesn’t know!

  7. Leigh says:

    I always thought flatbread was different because the ingredients were different. The texture of the bread always seemed different than pizza crust. I like both though! Always. And yes!! Your title completely made my mouth water!

    1. Robyn Stone says:

      Thanks so much, Leigh. You may be on to something!

  8. Wenderly says:

    I could dive into that mouth open right now!!!!

    1. Robyn Stone says:

      Thanks so much, Wendy. It always disappears in a flash!

  9. Jen @ My Kitchen Addiction says:

    I’ve often debated the difference between flatbreads and pizzas… And, then there are those restaurant menus that have “flatbread pizzas”… Hmmm, redundant? Anyway, whatever you call it, this looks absolutely fabulous. Love the pairing of caramelized onion and thyme!

    1. Robyn Stone says:

      Thanks so much, Jen. That does sound a bit redundant, doesn’t it. I’m with you though, whatever it should be called, I love it!

  10. Rachel Cooks says:

    I love caramelized onions and I love thyme…this is right up my alley. I bet it would be great with bacon too!

    1. Robyn Stone says:

      Oh my goodness, Rachel. You are so speaking my language with the addition of bacon! YUM!
