Preheat your oven to 425°F (220°C).
In a large bowl, mix together the flour, baking powder, salt, and parsley flakes.
In a separate bowl or measuring cup, whisk together the cottage cheese, vegetable oil, milk, and egg until well combined.
Make a well in the center of the dry ingredients and pour in the cottage cheese mixture. Mix until the dough comes together in a shaggy form. It’s okay if there are a few dry spots.
Turn the dough out onto a lightly floured surface and knead it a few times until the dough is smooth and cohesive. Press the dough out to about 3/4 inch thick.
Using a 2 3/4 inch round cutter, cut out the biscuits by pressing the cutter straight down. Gather and re-roll the remaining dough as needed to cut out more biscuits.
Place the biscuits on a baking sheet that has been lightly sprayed with non-stick spray or lined with parchment paper. The biscuits should be almost touching each other.
Place the baking sheet on the center rack of the preheated oven and bake for 10-12 minutes, or until the biscuits are risen and golden brown.
