A creamy, cheesy brunch casserole featuring Gruyere cheese, fresh herbs, and a subtle sparkle from champagne, perfect for a fuss-free weekend meal.
Use day-old bread to prevent sogginess. Let the custard rest on the bread before baking for best texture. If the top browns too quickly, tent with foil halfway through baking. For gluten-free, use gluten-free bread or cubed cooked potatoes. For dairy-free, substitute cream and cheese with plant-based alternatives.
