Preheat oven to 300℉. Move one oven rack to the center of the oven and one to the bottom. Place an oven safe dish or skillet in the bottom rack. Boil 4 cups of water. Grease or line 12 muffin cups with liners.
In a blender combine eggs, egg whites, cottage cheese, salt and pepper.
Divide roasted red peppers and shredded cheese between all muffin cups. Pour egg mixture into each cup.
Fill the dish in on the bottom rack of oven with boiling water, working fast to keep the steam trapped in the oven.
Bake the muffin cups on the middle rack of the oven for 30-35 minutes or until set.
Notes
Muffin tin liners make prep and cleanup easier. Silicone muffin tins or liners don't need to be greased.
Opt for a metal baking dish for the boiling water, instead of glass.
The center muffins may take a little longer to bake than the ones on the edges.
