Preheat the oven to 350 degrees Fahrenheit. In a large bowl, mix together the eggs, milk, rosemary, salt, 1/4 teaspoon of the black pepper and 1/2 teaspoon of the fresh parsley. Add the bread, garlic, sausage, cheddar, and 3/4 cup of the gouda. Mix until the bread pieces are soft and wet. You may want to let them sit in the bowl for 5 minutes to help with the absorption if they're not soaked through right away.
