Amys Kitchen Creations: Eggs for breakfast sandwiches Spray your muffin pan with some non-stick cooking spray. Crack one egg into each well. Sprinkle the eggs with a little salt & pepper or whatever seasonings that you'd like. Bake in the oven at 350 for about 15 minutes. You could cook them for a bit less if you wanted a runny yolk. However, I wanted to be sure that the eggs were fully cooked.
