Preheat your oven to 400°F (200°C).
Wash the potatoes thoroughly and slice them into 1/4-inch thick rounds.
Place the potato slices on a baking sheet lined with parchment paper.
Brush both sides of each potato slice with olive oil and season with salt and pepper.
Bake the potato slices in the preheated oven for 20-30 minutes, flipping them halfway through, until they are tender and slightly golden.
Remove the potato slices from the oven and spread a small amount of pizza sauce on each slice.
Sprinkle shredded mozzarella cheese over the sauce.
Add your favorite toppings on top of the cheese.
Return the potato pizzas to the oven and bake for an additional 5-7 minutes, or until the cheese is melted and bubbly.
Let the potato pizzas cool slightly before serving.
Serve and enjoy!
