Preheat and line pans: Preheat the oven to 375°F and line two baking sheets with parchment paper. Avoid silicone mats, since the thin batter can stick to them as it bakes.
Blend cottage cheese smooth: Add the cottage cheese to a blender or food processor and blend until completely smooth, about 1 minute, with no visible curds left.
Stir in seasonings: Pour the blended cottage cheese into a bowl and stir in the parmesan, garlic powder, onion powder, smoked paprika, salt, and pepper until the batter is an even color.
Portion the batter: Drop tablespoon-sized mounds of batter onto the lined baking sheets, spacing them about 2 inches apart to leave room for spreading.
Spread into thin rounds: Use the back of a spoon to spread each mound into a thin circle about 3 inches wide, spreading until the center is almost translucent.
Add optional topping: Sprinkle everything bagel seasoning over the tops if using, pressing lightly so it sticks to the batter.
Bake the first side: Bake for 20 to 25 minutes, until the edges turn deep golden and lacy and the centers look set and dry, not glossy.
Flip each chip: Remove the pan and carefully flip each chip using a thin metal spatula, working slowly since the edges are delicate.
Bake the second side: Return the pan to the oven and bake 8 to 10 more minutes, until the chips are fully golden on both sides and feel firm, not soft, when pressed.
Cool on a rack: Transfer the chips to a wire rack and let them cool for 10 minutes; they crisp further as they cool, so avoid stacking them while warm.
Store for later: Keep cooled chips in an airtight container at room temperature for up to 3 days, re-crisping briefly in a 350°F oven if they soften.
