Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper.

In a large mixing bowl, combine the lean ground turkey, large egg, grated Parmesan cheese, almond flour, garlic powder, onion powder, Italian seasoning, salt, and black pepper.

Using your hands, mix all the ingredients thoroughly until well combined. Ensure there are no large lumps and the mixture is uniform.

Transfer the turkey mixture onto the prepared baking sheet. Using a spatula or your hands, spread the mixture evenly into a circular shape, about 1/4 to 1/2 inch thick, forming a pizza crust approximately 9-10 inches in diameter. You can slightly raise the edges to create a rim.

Bake the turkey crust for 20-25 minutes, or until it is firm, cooked through, and lightly browned. Some liquid may release from the turkey; you can carefully blot it with a paper towel if desired.

Remove the crust from the oven. Carefully add your desired low-carb pizza toppings (such as sugar-free tomato sauce, mozzarella cheese, and your choice of meats and vegetables).

Return the topped pizza to the oven and bake for an additional 5-10 minutes, or until the cheese is melted and bubbly and the toppings are heated through. Slice and serve immediately.
