Ultra-Thin-Crust Pizza with Onions, Mushrooms, and 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 Everyday Food magazine.

The trick is to keep the toppings thin and light, otherwise the crust will end up being soggy. It really helps to use a pizza stone; the pizza will cook up faster and crisper. I’ve included directions for both using a stone and not.

Ultra-Thin-Crust Pizza with Onions, Mushrooms, and Ricotta Recipe



  • Olive oil
  • 1 small red onion, halved and thinly sliced
  • Pinch of sugar
  • 1 teaspoon balsamic vinegar
  • 2 large flour tortillas (sandwich wraps)
  • 1 cup shredded Asiago cheese (about 2 ounces)
  • 2/3 cup ricotta cheese
  • 6 button or cremini mushrooms, trimmed and thinly sliced
  • Kosher salt and freshly ground black pepper

Equipment needed:
It really helps to have a baking stone and a pizza peel. If not, you'll use a rimmed baking sheet with some parchment paper.


1a If you are using a baking stone, place the stone on top of the middle rack in the oven. Preheat the oven to 450°F. Allow the oven to stay at 450°F for at least 15 minutes before cooking, to thoroughly heat up the stone.

1b If you are NOT using a baking stone, place racks in the upper and lower thirds of the oven. Preheat the oven to 450°F.

2 Heat 1 Tbsp olive oil in a small sauté pan on medium hight 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.

3a If you are using a baking stone, sprinkle some corn meal on your pizza peel and place one tortilla on top of the pizza peel. (If you don't have a pizza peel, you can use a rimless baking sheet.) Thoroughly brush the top of the tortilla with olive oil.

3b If you are not using a baking stone, line two rimmed baking sheets with parchment paper and brush with olive oil. Place a tortilla on each baking sheet and brush each with olive oil.

4 Sprinkle each tortilla with half a cup of shredded Asiago cheese. Add bits of ricotta cheese, 1/3 cup for each tortilla. Sprinkle with mushrooms and with the slightly caramelized onions. Sprinkle with a little salt and pepper.

5a If you are using a baking stone, and can fit both pizzas on the stone (it depends on the size of your tortilla) do it. Use the pizza peel to transfer the pizzas to the stone in the oven. If your tortillas are large, you'll need to cook them one at a time. But that's okay. Cooking on the stone goes very quickly. Bake the pizzas until the crust is crisp and very brown - 5-7 minutes using the baking stone. Cut with a pizza cutter or a knife.

5b If you are using baking sheets, place the baking sheets in the oven. Bake until the crust is crisp and brown all over (the time varies, depending on the oven and if your cookie sheet has already been heated, start with 10 minutes and check), rotating the sheets to ensure even baking. Cut with a pizza cutter or a knife.

Each pizza serves 1-2, depending on how hungry you are.

    My sisters and I grew up making and eating these since the 70’s, with our dad. He had the recipe published in a y m c a cookbook back in those days, and I have it

    We love these. We use different kinds of sandwich wraps and any vegetables we have in the fridge. One of our favorites is red onion, mushroom, sliced broccoli florets and olives.

    This looks so amazing! I’m new to cooking and am going to try something like this cuz I splurged on a pizza stone – I made fresh pesto (first time ever) and want to try that on it. Do you think it would work? Any suggestions of what else to put on it? I just love this idea because it looks simple and carb friendly ;-) Thank you!

    I love fresh pesto on pizza. Great with caramelized onions. ~Elise

    I think this recipe is awesome! I am not much of a cook, and if I can do something, someone else definitely can! I couldn’t find ricotta at trader joe’s so I used mozarella instead. I used 100% wheat flour and had very thin slices of tomatoes to put atop it all (bake it), then added fresh tomatoes on top. It tasted quite good! Thanks for sharing. I really like your blog and your pictures. Cheers!

    I do something very similar to this, except mine is a breakfast pizza. I let the tortilla get nice and crispy in the oven first while I make some scrambled eggs and country gravy and fry up some sausage, then I use the gravy as a sauce, spread a thin layer of shredded cheese over it, put on the eggs and sausage and then sprinkle a little more cheese over the top to hold all the toppings together, and then stick it under the broiler just long enough to melt the cheese. Makes an amazing and fairly easy breakfast, takes a little prep work but my bus driver used to love these, and so did her four year old grandson that sometimes tagged along for the ride before he went to preschool!

    What a great idea, thanks for sharing! ~Elise
