Blue Potato, Mushroom & Caramelized Onion Flatbread Pizza

March 09, 2021

While I love trying out the pizza shops all over New York, it’s sometimes nice to make one at home. With this easy recipe, I’ve opted for a flatbread as a base so you don’t have to fret about yeast. It rises a bit with the help of baking powder and then you can go to town with toppings. This combo of blue potato, caramelized onions, mushrooms and cheese makes for a unique take on a veggie delight. 



1 tablespoon + ¼ cup olive oil, divided

2 medium-sized yellow onions, sliced

1 quart water

1 tablespoon kosher salt

3 small blue potatoes

4 cloves organic garlic, minced

1 cup mozzarella cheese, shredded

1/3 cup feta cheese, crumbled

1 large mushroom cap, sliced 

Cilantro sprigs and zest of 1 lime, for garnish 

Pizza Dough:*

2 cups all-purpose flour

3/4 teaspoon kosher salt 

1 teaspoon baking powder

3/4 cup warm water 

2 tablespoons olive oil 

Cornmeal, for dusting

*you can also cheat and use our organic pizza dough!


Preparing Toppings: 

  1. In a skillet, cook 1 tablespoon of oil and sliced onions together over medium-high heat until the onions are golden brown. Stir occasionally to avoid burning. It can take up to 25-30 minutes to caramelize onions. Once they are done, set them aside to cool completely. 
  2. In a small pot, boil a quart of water and kosher salt. Once it starts boiling, add whole blue potatoes and boil until they’re cooked, 10-12 minutes. Drain the water and let the potatoes cool completely. Slice thin and into half-moon pieces.

Pizza Dough + Assembly: 

  1. Preheat oven to 425°F. Dust your 12x18 baking sheet with cornmeal. Set aside.
  2. In a large bowl, mix dry ingredients, warm water and 2 tablespoons of olive oil with a wooden spoon. Take the dough and knead on a clean surface until it becomes nice and smooth, 3-5 minutes. 
  3. Cover the dough with a kitchen towel and let it rest for 10 minutes.
  4. Roll out dough thin and shape it into a long oval to place onto your 12x18 baking sheet. 
  5. Dock the surface of the rolled out dough by pricking it all over with a fork. 
  6. Bake flatbread for 5-7 minutes or until the edges turn golden brown.
  7. Take the baking sheet out of the oven and brush the flatbread’s surface with 1/4 cup of olive oil. Proceed with covering them with toppings in the following steps.
  8. Sprinkle the minced garlic on top, and follow with the mozzarella cheese. 
  9. Scatter blue potato pieces, feta, mushroom slices and dollops of caramelized onions on top. 
  10. Put flatbread pizza back in the oven and bake for 10-12 minutes until the cheese is melted and the crust is browned. Garnish with sprigs of cilantro and lime zest. Serve warm.
