First, attach your sous vide to the edge of a stock pot (that will fit the egg bite mold) and fill halfway with warm water. Preheat your sous vide to 185 degrees F.
Meanwhile, in a high-powered blender, add the eggs, cottage cheese, Monterey Jack cheese, Gruyere cheese, salt, pepper, garlic powder and cayenne pepper (if using). Blend on medium-high until very smooth.
Finely dice your bacon and evenly distribute the bits in the bottom of each egg bite mold. Next, evenly distribute the egg mixture into each of the egg bite molds until just full. Place the silicone lid on the egg mold.
When your sous vide is preheated and ready, using a sturdy spatula, carefully lower the egg mold into the water and cook until the egg bites have set, 25 to 45 minutes. *I know this is a wide range, but sometimes the egg bites take longer to set.. mine typically takes 25 minutes, you can check to see if the egg bites have set by simply jiggling the egg mold and making sure the tops are no longer liquidy.*
When the cook time is complete, using a sturdy spatula carefully lift the egg mold from the water and set aside. Uncover and let cool for 10 minutes. To remove the egg bites from the mold, I carefully loosen up the edges using a mini-silicone spatula or butter knife around the edges of the cooked egg bit, then flip to remove from the mold onto a cutting board.
