Preheat your oven to 300°F (150°C). Grease a 12-cup muffin tin well, or line with silicone liners.
Combine the cottage cheese, milk, eggs, salt, and pepper in a blender. Blend until the mixture is completely smooth. This step creates the fluffy texture.
If using mix-ins like bacon or cheese, stir them into the blended egg mixture now.
Pour the egg mixture evenly into the prepared muffin cups, filling each about three-quarters full.
Bake for 20 to 25 minutes, or until the egg bites are set and a toothpick inserted in the center comes out clean.
Let the egg bites cool in the muffin tin for 5 minutes before removing them.
For meal prep, cool completely, then store in an airtight container in the refrigerator for up to 4 days or freeze for later use.
Notes
For a Starbucks sous vide copycat texture, you can use an Instant Pot with a trivet and silicone molds, cooking on High Pressure for 8 minutes followed by a 5-minute natural release.
You can substitute Greek yogurt for cottage cheese for a slightly different texture.
Add cooked sausage or chopped broccoli for variety in your next batch.
