Pre-heat oven to 300ºF and place a baking dish that is filled with 1 inch of water on the bottom rack.
Add the eggs, cheese, cottage cheese, salt, and pepper to a blender and blend on high for 20 seconds until light and frothy.
Grease a ¼ sheet pan (9×13) rimmed sheet pan with cooking spray, line with parchment paper, and spray again.
Pour the egg mixture into the prepared sheet pan and bake in the oven for 30-35 minutes, or until the center of the eggs are just set.
Remove from oven and let cool for 5 minutes, slice into portions, and serve.
