Preheat oven to 400˚F.
In a small pot over low heat, melt the butter with the crushed garlic clove. Using a pastry brush, brush the inside of a casserole dish with some of the melted butter to keep the eggs from sticking.
Cut the loaf of bread in to 8 pieces, each about 1 to 1 1/2 inches long. Using a cookie cutter about an inch in diameter, cut a hole into the middle of each piece of bread. Place the pieces of bread into a casserole dish.
Using a pastry brush, brush each of the slices of bread with the melted garlic-butter then sprinkle with parsley and Parmigiano cheese.
Crack an egg into a small bowl and pour it into one of the bread holes. Repeat until all the bread “nests” are filled with an egg.
