Preheat oven to 350 degrees and prep your silicone muffin pan. Spray silicone muffin pan with non-stick spray and place into a large baking sheet.
Using a blender, blend together the eggs, cottage cheese and shredded mozzarella cheese until smooth. Remove blender pitcher from base and add the garlic and onion powder and the crushed red pepper flakes (if using). Season with salt and pepper and mix together by hand with a spoon or whisk.
Pour the egg mixture evenly into each muffin pan cavity about 3/4 of the way full until all of the egg mixture is gone. You should be able to fill all 12.
If wanting your vegetables more evenly distributed into the egg bites: using a small separate bowl, mix together the onions* (read note re: the onions below), red bell peppers and spinach and sprinkle evenly over the egg mixture in each muffin cavity.
If wanting to just mix everything together, proceed this way: Using a blender, blend together the eggs, cottage cheese and shredded mozzarella cheese until smooth. Remove blender pitcher from base and add the onions* (read note re: the onions below), red bell peppers and spinach into the blender pitcher with the egg mixture. Add the garlic and onion powder and the crushed red pepper flakes (if using). Season with salt and pepper and mix together by hand with a spoon or whisk.
Pour the egg mixture evenly into each muffin pan cavity about 3/4 of the way full until all of the egg mixture is gone. Place baking sheet into preheated oven and pour boiling water** into the baking sheet; enough water to cover the bottoms of the muffin pan (about a 1/2 inch of water).
Bake for about 30 to 35 minutes. Check egg bites after 30 minutes. You want the egg bite tops to be firm to the touch. Carefully remove the entire pan from the oven and carefully pour out the water. Let the egg bites cool for about 5 minutes before removing from the muffin pan mold. Enjoy!
