Ingredients
Scale
- 6 large croissants, torn into bite-sized pieces
- 8 oz (225 g) cooked ham, diced or sliced
- 2 cups (200 g) shredded Swiss or Gruyère cheese
- 1/2 cup (50 g) shredded cheddar cheese (optional)
- 8 large eggs
- 2 cups (480 ml) whole milk
- 1/2 cup (120 ml) heavy cream
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1/4 tsp ground mustard (optional)
- 1/4 tsp garlic powder (optional)
- 2 tbsp fresh parsley, chopped (optional, for garnish)
Instructions
- Prepare the Dish:
- Grease a 9×13-inch baking dish. Spread the torn croissant pieces evenly in the dish. Top with the diced ham and shredded Swiss cheese.
- Make the Custard:
- In a large mixing bowl, whisk together the eggs, milk, cream, salt, pepper, ground mustard, and garlic powder until well combined.
- Assemble the Casserole:
- Pour the egg custard mixture evenly over the croissants, ham, and cheese. Press down gently to ensure the croissants soak up the custard. Cover the dish with plastic wrap or foil and refrigerate for at least 1 hour, or overnight for the best results.
- Bake:
- Preheat your oven to 375°F (190°C). Remove the casserole from the fridge and let it sit at room temperature for 15 minutes.
- Bake uncovered for 30-35 minutes, or until the custard is set and the top is golden brown.
- Garnish and Serve:
- Let the casserole cool for 5 minutes. Sprinkle with chopped parsley before serving.
Notes
- Substitute the ham with cooked bacon, sausage, or a vegetarian alternative for variety.
- Leftovers can be stored in the refrigerator for up to 3 days and reheated in the oven or microwave.
- Add sautéed spinach, mushrooms, or onions for extra flavor and texture.
