Step-by-Step Instructions
1. Preheat and Prepare
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish. Trim the woody ends from the asparagus and blanch them in boiling water for 2–3 minutes until bright green. Drain and set aside.
2. Make the Cheese Sauce
In a medium saucepan, melt butter over medium heat. Whisk in flour and cook for 1–2 minutes until lightly golden. Gradually whisk in milk, stirring constantly until the mixture thickens. Remove from heat and stir in cheddar, Parmesan, garlic powder, salt, and pepper until smooth.
3. Assemble the Casserole
Arrange the blanched asparagus evenly in the prepared baking dish. Pour the cheese sauce over the top, ensuring all spears are coated. Sprinkle extra cheddar and breadcrumbs on top for a golden, crunchy crust.
4. Bake
Bake uncovered for 20–25 minutes, or until the cheese is bubbly and the top is golden brown.
5. Serve and Enjoy
Let the casserole rest for 5 minutes before serving. This allows the sauce to set slightly and makes it easier to serve.
