01 - Preheat oven to 350°F. Generously grease a 12-cup muffin tin with nonstick cooking spray or oil to ensure easy removal.
02 - Crack eggs into a large mixing bowl. Whisk vigorously until yolks and whites are completely blended and the mixture is 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 incorporated.
04 - Gently fold in the chopped spinach, diced red bell pepper, and sliced green onions using a spatula. Distribute vegetables evenly throughout the mixture.
05 - Pour the egg mixture into the prepared muffin tin, dividing evenly among all 12 cups. Fill each cup approximately three-quarters full to allow for rising during baking.
06 - Bake for 22 to 25 minutes. The egg bites are done when they are fully set, no longer jiggly in the center, and lightly golden on top.
07 - Let the egg bites cool in the tin for 3 to 5 minutes. Run a knife around the edges if needed, then gently remove. Serve warm or allow to cool completely for room temperature serving.
