Preheat oven to 425 degrees and line a baking sheet with foil.
Pour 1/2 a cup of the marinara sauce into two 6 inch cast iron skillets or two 10 ounce ramekins.
Top the marinara sauce with 2 tablespoons each of parmesan cheese.
Gently crack 2 eggs into each skillet.
Top the eggs with salt and pepper then place them on the foil lined baking sheet.
Bake the eggs in the oven for 10-15 minutes or until the whites of the eggs are set.
Remove from the oven and sprinkle with parsley or basil if desired.
Serve immediately with toasted baguette slices.
