Flatbread With Caramelized Onions, Portobello Mushrooms, and Gorgonzola Crumbles

I have noticed a trend in many restaurants we frequent locally that has become very popular. This trend is for flatbreads that are topped with a variety of seasonal ingredients. I love trying these flatbreads, some that have a cracker crisp crust, while others have a thicker crust similar to focaccia. These flatbreads are cut into small pieces and are great enjoyed as an appetizer.

Personally, I prefer my flatbread crust to be somewhere between cracker thin and as thick as a focaccia. Recently, while dining out with my husband, we shared a mushroom and caramelized onion topped flatbread that was sprinkled with Gorgonzola cheese crumbles. The combination of the sweet golden brown onions, earthy mushrooms, and salty blue cheese crumbles was delicious, so I knew I had to make it at home.

For these flatbreads, you can either buy your pizza dough already made or make your own using one of my pizza dough recipes. A sixteen ounce ball of dough will make two good sized flatbreads and easily serve four to six as an appetizer.

We are trying to adhere to a plant-based diet lately, so I left my flatbread vegetarian, but pancetta, diced and sautéed first would also be tasty on this flatbread as well. I roll my flatbread dough out to a 1/4-inch thickness and find that dough is best rolled when at room temperature.



Buon Appetito!

  1. Hi
    Last year I made a trip to Tuscany with my friends. We are nature lovers and Tuscany is the ideal destination for this. We made many excursions in the hills of Tuscany and cities of art. We stayed in a farmhouse near St. Gimigano really nice; It called Torre Prima.
