Preheat the oven:
Preheat your oven to 300°F (150°C). Place a baking sheet on the middle rack to serve as a water bath (this helps keep the egg bites moist).
Prepare the egg mixture:
In a blender, combine the eggs, cottage cheese, salt, and pepper. Blend until smooth and frothy.
Assemble the egg bites:
If using bacon or vegetables, divide them evenly into the silicone molds or greased muffin tin. Pour the blended egg mixture over the fillings, filling each mold about 3/4 full.
Bake in a water bath:
Place the filled molds or muffin tin on the baking sheet. Carefully pour hot water into the sheet to create a water bath. Bake for 30–35 minutes, or until the egg bites are set and slightly golden on top.
Cool and serve:
Allow the egg bites to cool for a few minutes before removing them from the molds. Serve warm, or store in the fridge for up to 5 days for an easy, reheatable breakfast.
