Instructions

• Grease a 9-by-13-inch baking dish and arrange the croissant pieces evenly inside.
• Whisk the eggs, milk, salt, and pepper until smooth, then pour the custard over the croissants.
• Sprinkle the cheddar evenly over the top, cover the dish, and refrigerate for at least 8 hours.
• Let the casserole stand at room temperature for 20 minutes while the oven heats to 350°F.
• Bake uncovered for 40 to 45 minutes, until the center is set and the top is golden.
• Rest for 10 minutes, garnish with chives if using, and cut into portions.
