01 - Preheat oven to 350°F. Lightly grease a 12-cup muffin tin with nonstick cooking spray or line with silicone liners.
02 - Add cottage cheese, eggs, cheddar cheese, Parmesan, salt, pepper, and garlic powder to a blender. Blend on high speed until completely smooth and creamy, approximately 30-45 seconds.
03 - In a large mixing bowl, combine chopped spinach, diced bell pepper, sliced green onions, and any optional add-ins such as cooked bacon or smoked paprika.
04 - Pour the blended egg mixture over the vegetables. Gently fold together using a spatula just until evenly combined, taking care not to overmix.
05 - Divide the mixture evenly among the 12 prepared muffin cups, filling each approximately three-quarters full. The batter will puff slightly during baking.
06 - Bake for 22 to 25 minutes until centers are completely set and tops are lightly golden brown. A toothpick inserted into the center should come out clean.
07 - Let the egg bites cool in the muffin tin for 5 minutes before removing. Serve warm, at room temperature, or refrigerate for meal prep.
