Preheat your oven to 350°F (175°C).
In a large saucepan, bring water to a boil. Add the asparagus and cook for 2-3 minutes until bright green and tender-crisp. Drain and set aside.
Make the Cheese Sauce:
In the same saucepan, melt the butter over medium heat. Stir in the flour and cook for 1-2 minutes to form a roux.
Gradually whisk in the milk, stirring constantly until the mixture thickens, about 3-4 minutes.
Remove from heat and stir in the shredded cheddar cheese, Parmesan cheese, garlic powder, salt, and pepper until smooth.
Assemble the Casserole:
In a baking dish, layer the cooked asparagus. Pour the cheese sauce evenly over the asparagus.
Prepare the Topping:
In a small bowl, mix the breadcrumbs with the melted butter until evenly coated. Sprinkle the breadcrumb mixture over the casserole.
Bake:
Bake in the preheated oven for 20-25 minutes, or until the casserole is bubbly and the topping is golden brown.
Serve:
Allow the casserole to cool slightly before serving. Enjoy it as a delightful side dish or a light vegetarian main course.
