Preheat the oven to 425 F. Line a baking sheet with parchment paper and lightly coat it with half of the olive oil.
Blend the cottage cheese, eggs, and remaining olive oil until completely smooth.
Whisk together the brown rice flour, tapioca flour, psyllium husk, baking powder, onion powder, and salt. Stir in the cottage cheese mixture until a thick batter forms.
Let the batter rest for 12 minutes. Spread it into a 12-inch circle about 1/4-inch thick, using a lightly oiled spatula to smooth the surface.
Bake for 18 to 21 minutes, until the crust is firm and golden around the edge. Turn it over and remove the parchment.
Bake for another 6 to 8 minutes, until the bottom is crisp and lightly browned. Rest the crust for 4 minutes before adding toppings.
