Preheat Like a Pro: Preheat your oven to 375°F and line a sheet pan with parchment paper. Give that parchment a light spray of oil so our flatbread lifts off like a dream later.
Blend the Magic: Add cottage cheese, eggs, psyllium husk powder, baking powder, garlic powder, onion powder, and kosher salt to a blender. Blend until completely smooth. We’re looking for a silky batter with no curds left behind.
Bring in the Cheese: Pour the mixture into a bowl and stir in the shredded mozzarella and parmesan. These melty pockets of cheese are what help the flatbread stay soft and flexible instead of baking up stiff.
Spread It Out: Pour the batter onto your parchment-lined pan and spread it into a thin rectangle about 1/8-inch thick. Think tortilla thin, not pancake thick.
Bake Until Beautiful: Bake for 22 to 28 minutes until the center is set and the top looks lightly golden. Your kitchen should smell like a cozy brunch spot by now.
Let It Chill (Important!): Let the flatbread cool for about 10 minutes before lifting it. This step lets the structure settle so it becomes flexible enough to wrap without cracking.
