Ultra-thin Crust Pizza with Onions, Mushrooms, Ricotta

When I first encountered a recipe for a thin-crust pizza using a flour tortilla as a base I was indignant. "That's not a pizza! That's a quesadilla!" But I soon got over my ire.

This approach is actually rather brilliant, a great example of borrowing from one cuisine to expand another. The recipe for this thin-crust pizza is inspired by one I found in an old issue of the now defunct Everyday Food magazine.

The trick is to keep the toppings thin and light, otherwise the crust will end up being soggy.

Tortilla Pizza with Onions, Mushrooms, and Ricotta

Prep Time 10 mins
Cook Time 20 mins
Total Time 30 mins
Servings 2 servings


  • 1 tablespoon extra virgin olive oil, plus more for brushing on tortilla and pan

  • 1 small red onion, halved and thinly sliced, about 3/4 cup sliced

  • Pinch sugar

  • 1 teaspoon balsamic vinegar

  • 2 large flour tortillas (sandwich wraps)

  • 1/2 cup Asiago cheese, shredded

  • 2/3 cup ricotta cheese

  • 4 button or cremini mushrooms, trimmed and thinly sliced

  • Kosher salt and freshly ground black pepper


  1. Preheat oven:

    Place racks in the upper and lower thirds of the oven. Preheat the oven to 450°F.

  2. Sauté onions:

    Heat 1 Tbsp olive oil in a small sauté pan on medium high heat. Add the sliced onions and cook, stirring occasionally, until the onions begin to soften.

    Add a pinch of sugar and the balsamic vinegar, cook for a few more minutes until the onions are thoroughly softened and translucent. Remove from heat.

  3. Brush sheet pan and tortillas with olive oil:

    Brush a sheet pan with olive oil. Place a tortilla on each baking sheet and brush each with olive oil.

  4. Sprinkle tortillas with cheese, mushrooms, onions:

    Sprinkle each tortilla with half a cup of shredded Asiago cheese. Add bits of ricotta cheese, 1/4 cup for each tortilla.

    Sprinkle with mushrooms and with the slightly caramelized onions. Sprinkle with a little salt and pepper.

  5. Bake:

    Place the baking sheets in the oven. Bake until the crust is crisp and brown all over, about 10 minutes (the time varies, depending on the oven), rotating the sheet pans and swapping out their positions on the racks halfway through the cooking to ensure even baking.

    Cut with a pizza cutter or a knife.
