Creating your Rustic Artichoke & Leek Bread Pudding is simple if you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
2. Sauté Leeks: In a skillet, heat olive oil over medium heat. Add the leeks and sauté until soft, about 5 minutes. Remove from heat.
3. Combine Ingredients: In a large bowl, combine the bread cubes, sautéed leeks, and artichoke hearts.
4. Make Custard Mixture: In a separate bowl, whisk together the milk, eggs, Parmesan cheese, salt, pepper, thyme, and garlic powder until well combined.
5. Combine Mixtures: Pour the custard mixture over the bread and vegetable mixture, ensuring all bread pieces are coated. Let it sit for about 15 minutes to allow the bread to absorb the liquid.
6. Transfer to Baking Dish: Transfer the mixture into the greased baking dish, spreading it evenly.
7. Bake: Place in the preheated oven and bake for 40-45 minutes or until the top is golden and a knife inserted in the center comes out clean.
8. Cool: Remove from the oven and let it cool for 5-10 minutes before serving.
9. Garnish: If desired, sprinkle with fresh parsley for added flavor and color.

These steps will guide you in creating this incredible bread pudding effortlessly.
