01 - Preheat oven to 350°F. Grease a 12-cup muffin tin thoroughly with nonstick cooking spray or a small amount of oil.
02 - Crack all 6 eggs into a large mixing bowl. Whisk vigorously until yolks and whites are completely blended and uniform in color.
03 - Add cottage cheese, shredded cheddar, grated parmesan, salt, black pepper, and smoked paprika to the eggs. Whisk until all ingredients are evenly distributed throughout the mixture.
04 - Gently fold in the chopped spinach, diced red bell pepper, and sliced green onions using a spatula. Be careful not to overmix.
05 - Pour the egg mixture evenly into the prepared muffin tin cups, filling each approximately 3/4 full to allow for rising during baking.
06 - Place muffin tin in the preheated oven. Bake for 22 to 25 minutes until the egg bites are completely set in the center and the tops are lightly golden brown.
07 - Remove from oven and let cool in the tin for 3 to 5 minutes. Gently run a knife around the edges to loosen, then remove from the pan. Serve warm or at room temperature.
