I got this recipe from the Food Channel
Ingredient weights and volumes rarely explain how high water content dictates structural integrity. Fresh cherry tomatoes introduce significant moisture during baking, which raw or dried variants do not. Cooking those tomatoes briefly over medium-high heat drives off excess surface liquid before the mixture enters the oven. Without that preliminary sauté step, internal steam turns the custard into a sodden mass rather than a cohesive set dish.
Multi-grain loaves require specific treatment to absorb liquids evenly without dissolving. Cut the bread into uniform 3/4-inch cubes so each piece maintains structural resistance during the 25 to 30 minute bake time at 375 degrees. Parmesan cheese acts as a secondary binder, melting to coat the crumb while absorbing free water.
