01 - Preheat oven to 350°F. Generously grease a 12-cup muffin tin with non-stick spray or line with silicone muffin liners for easy removal.
02 - Add eggs, cottage cheese, milk, salt, pepper, and garlic powder to a blender. Blend on high speed until completely smooth and frothy, about 30-45 seconds.
03 - In a large mixing bowl, toss together spinach, red bell pepper, green onions, and shredded cheddar cheese until evenly distributed.
04 - Pour the blended egg mixture over the vegetables and cheese. Using a spatula, gently fold until just combined—avoid overmixing to keep the texture light.
05 - Divide the mixture evenly among the 12 muffin cups, filling each about three-quarters full. The egg bites will puff up during baking.
06 - Bake for 18-22 minutes, or until the egg bites are fully set and the tops are lightly golden. A toothpick inserted in the center should come out clean.
07 - Let the egg bites cool in the muffin tin for 5 minutes. Run a thin knife around the edges to release, then carefully lift out. Serve warm or at room temperature.
