Preheat the oven to 425°F. Line a baking sheet with parchment paper and set aside.
In a microwave-safe bowl, heat the mozzarella cheese in 30-second intervals, stirring after each, until it is very melted and stretchy—typically 1-2 minutes total.
Add the almond flour and Italian seasoning to the melted cheese. Fold together with a spoon or spatula until thoroughly combined and no dry flour remains.
Add the egg and mix until a sticky, uniform dough forms. If the dough becomes too stiff, microwave it for 10–15 seconds to soften.
Place the dough on the prepared parchment-lined baking sheet. With damp hands, knead lightly just until the dough is even in color and texture. To prevent sticking, you can knead or shape the dough between two sheets of parchment paper.
Roll out the dough to your desired thickness, aiming for about 1/8 inch for a classic pizza crust. Prick holes all over with a fork to prevent bubbling as it bakes.
Bake for 7-10 minutes, until the crust is golden at the edges and firm to the touch—look for a pale golden color and set, slightly puffed texture. Remove from oven.
Optional: Add your preferred pizza toppings and return to the oven or broiler for 5-10 minutes until the cheese topping is bubbly and starting to brown.
