This Smashed Potato Onion Tomato Pizza is not what you might expect. It’s gluten-free pizza like no other! Beautiful and delicious Mediterranean flavors sit atop a “crust” made entirely out of potato.
As a lover of smashed potatoes in general, I was inspired to make one giant smashed potato and use it as pizza crust. Here’s how to make it.
Ever since I tried it and loved it, I’ve been playing around with different delicious toppings, and the star ingredients in this one are caramelized onions and tomatoes.
What is a Smashed Potato Pizza?
A smashed potato pizza is a gluten-free pizza with a crust made out of 100% potato.
It can be topped with any ingredients you like, just as a regular pizza would be.
It doesn’t behave quite like a pizza with a typical bread crust. If it gets crispy enough on the bottom, it can be hand held, but it’s often easier to eat with a fork and knife.
What’s in Smashed Potato Onion Tomato Pizza?
- Smashed Potato Pizza Crust

How to Make Smashed Potato Onion Potato Pizza
- You can learn how to make the “crust” here, and you can make it up to 6 hours ahead of time.
- Once the crust is ready, sauté the onion until it’s caramelized.
Separately, cook the garlic and tomato purée until it reduces and is thick.
Spread the tomato mixture on the Smashed Potato Pizza Crust.
Sprinkle it with cheese and add a layer of basil leaves to cover everything.
Top with onions and tomatoes, drizzle with olive oil and sprinkle with salt and pepper.
Bake until the cheese is melted and the pizza is sizzling.
(More detailed instructions are below.)
Can you change the toppings?
Of course. I love this combination, but if you crave something different, go for it.
Can you make this Potato Onion Tomato Pizza on a different crust?
Sure! The directions would be the same for the toppings.
This is such an awesome way to make a gluten-free pizza crust!
I hope you love this pizza as much as I do.

Smashed Potato Onion Tomato Pizza
- 1 (10-inch) Smashed Potato Pizza Crust (Click here for the recipe)
- 1½ cups yellow onion, thinly sliced
- 1 teaspoon garlic, minced
- about ¾ cup cup tomato purée
- 1 cup white cheddar cheese, grated
- about 6 large basil leaves
- 1 Roma tomato, thinly sliced
- extra virgin olive oil for drizzling
- salt and freshly ground black pepper
- Preheat the oven to 400°F, and adjust a rack to the center.
- Coat the bottom of a medium-sized sauté pan with olive oil, add the onion and place it over medium-high heat. Stirring every so often, cook until the onions are soft and nicely browned, about 15 minutes. Set aside.
- While the onions are browning, add the garlic and tomato purée to a small sauce pan and place it over medium heat. Bring to a simmer and let it thicken and reduce a bit, about 10 minutes. Then season to taste with salt and pepper. (Here's how to season to taste.)
- Place the prepared Smashed Potato Pizza Crust on a parchment-lined baking sheet. Then use the back of a large spoon to spread the tomato sauce on its surface.
- Sprinkle the grated cheese evenly over the sauce and then add a layer of the basil leaves -- they should cover the cheese almost completely.
- Top with an even layer of the onions and tomato slices.
- Drizzle with olive oil and sprinkle with a bit more salt and pepper.
- Place in the preheated 400°F oven and bake until the cheese is melted and it's sizzling, 15 to 20 minutes.
- Let the pizza sit for about 10 minutes, slice and serve.
