In a blender, combine the eggs, cottage cheese, milk, salt, pepper, and smoked paprika. Blend until smooth for a silky texture.
Grease a 12-cup muffin tin or use silicone muffin liners. Evenly distribute the shredded cheese, bell peppers, bacon, and spinach among the cups.
Pour the egg mixture over the fillings, filling each cup about ¾ full. Place a baking pan filled with hot water on the oven’s lower rack to create steam, then bake at 325°F (160°C) for 15 minutes or until the egg bites are set.
Let the egg bites cool slightly before removing them from the tin. Serve warm or store for later!
