A creamy, cheesy brunch casserole featuring Gruyere cheese, fresh herbs, and a subtle sparkle from champagne, perfect for a fuss-free weekend meal.

Ingredients

Scale
  • 6 large eggs, room temperature
  • 1 cup heavy cream
  • 1/2 cup champagne (dry or brut)
  • 1 1/2 cups shredded Gruyere cheese
  • 2 tbsp chopped fresh parsley
  • 1 tbsp chopped fresh chives
  • 1 tsp fresh thyme leaves
  • Salt and freshly ground black pepper, to taste
  • 6 cups day-old bread cubes (sourdough or French bread)
  • 2 tbsp unsalted butter, melted
  • 1/2 tsp garlic powder (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease your 9×13-inch baking dish with the melted butter.
  2. Toss about 6 cups of day-old bread cubes with half of the fresh herbs, garlic powder, salt, and pepper. Spread evenly in the baking dish.
  3. In a large bowl, whisk together 6 large eggs, 1 cup heavy cream, and 1/2 cup champagne until fully blended and slightly frothy. Season with salt and pepper to taste.
  4. Fold in 1 1/2 cups shredded Gruyere cheese and the remaining chopped herbs into the custard mixture.
  5. Pour the custard evenly over the bread cubes and press down gently with a spatula. Let it sit for 10 minutes to allow the bread to absorb the liquid.
  6. Bake uncovered for 40-45 minutes until the casserole puffs slightly and the top is golden brown with bubbling edges. A toothpick inserted should come out mostly clean.
  7. Let the casserole cool for 5-10 minutes before serving to help it set and make slicing easier.

Notes

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.
