Ingredients
For the Casserole
- 1½ pounds fresh asparagus, trimmed and cut into 2-inch pieces (or 20 oz frozen, thawed)
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1½ cups chicken or vegetable broth
- ½ cup heavy cream or whole milk
- 1½ cups shredded sharp cheddar cheese, divided
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- Salt and black pepper to taste
For the Topping
- ½ cup panko breadcrumbs
- 1 tablespoon melted butter
- 1 tablespoon grated Parmesan cheese (optional)
Step-by-Step Instructions
- Prepare the asparagus.
If using fresh asparagus, blanch it in boiling salted water for about 2 minutes, then transfer to ice water to preserve the bright color and texture. If using frozen asparagus, thaw it completely and gently squeeze out excess moisture. - Make the roux.
In a large saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1–2 minutes to form a smooth paste. - Create the sauce.
Gradually whisk in the broth and cream, stirring constantly until the sauce thickens, about 3–5 minutes. - Add cheese and seasoning.
Reduce heat to low and stir in 1 cup of the shredded cheddar cheese, garlic powder, onion powder, salt, and pepper until smooth and creamy. - Combine the casserole.
Add the asparagus to the sauce and stir until evenly coated. Transfer the mixture to a greased 9×13-inch baking dish. - Add the cheese layer.
Sprinkle the remaining ½ cup shredded cheddar cheese evenly over the top. - Prepare the topping.
In a small bowl, mix the breadcrumbs, melted butter, and Parmesan cheese. Sprinkle this mixture over the casserole. - Bake.
Bake at 375°F (190°C) for 20–25 minutes until the casserole is bubbling and the topping turns golden brown. - Rest before serving.
Let the casserole rest for about 5 minutes before serving so the sauce can thicken slightly.
Tips for the Best Casserole
- Drain asparagus well to prevent a watery sauce.
