Creating Rustic Artichoke & Leek Bread Pudding is a delightful process. Follow these simple steps:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter or cooking spray.
2. Prepare Bread: Cut the crusty bread into cubes and set aside to dry slightly. If using fresh bread, you can leave it out for a few hours or toast it lightly to remove excess moisture.
3. Sauté Vegetables: In a skillet, heat the olive oil over medium heat. Add the sliced leeks and sauté until they become soft and translucent, about 5-7 minutes.
4. Mix Ingredients: In a large bowl, whisk together the eggs, milk, heavy cream, garlic powder, salt, pepper, and thyme until well combined.
5. Combine: Add the sautéed leeks and chopped artichokes to the egg mixture. Stir in the cubed bread and half of the grated Parmesan cheese, ensuring the bread is evenly coated with the mixture.
6. Transfer: Pour the mixture into the prepared baking dish. Press it down gently to ensure an even layer.
7. Top with Cheese: Sprinkle the remaining Parmesan cheese over the top of the bread pudding.
8. Bake: Place in the oven and bake for 45-50 minutes, or until the top is golden brown and the custard is set.
9. Cool: Remove from the oven and let it cool for about 10-15 minutes before serving. This will help the pudding set further.
10. Garnish: Optionally, sprinkle fresh parsley on top for added color and flavor before serving.

By following these steps, you will create an incredible dish that is sure to impress anyone who tastes it.
