For the Cheesy Asparagus Casserole: Gather the elements that will orchestrate this indulgent symphony on your palate:

  • 2 pounds fresh asparagus, trimmed: The star of the casserole, providing a crisp and vibrant base.
  • 2 tablespoons unsalted butter: Creating the foundation for the velvety cheese sauce.
  • 2 tablespoons all-purpose flour: Thickening the sauce for a creamy consistency.
  • 1 1/2 cups whole milk: The liquid base for the cheese sauce.
  • 1 cup shredded sharp cheddar cheese: Infusing a rich and tangy flavor.
  • 1/2 cup grated Parmesan cheese: Adding a nutty and salty depth.
  • 1/2 teaspoon Dijon mustard: Enhancing the cheese sauce with a hint of tang.
  • Salt and black pepper, to taste: Seasoning the dish to perfection.
  • 1 cup breadcrumbs: Creating a golden and crunchy topping.
  • 2 tablespoons melted butter: Binding the breadcrumbs and adding richness.



Step 1: Blanch the Asparagus Preheat your oven to 375°F (190°C). Bring a large pot of salted water to a boil. Add the trimmed asparagus and blanch for 2-3 minutes until slightly tender but still crisp. Immediately transfer to an ice water bath to stop the cooking process. Drain and set aside.

Step 2: Make the Cheese Sauce In a saucepan over medium heat, melt 2 tablespoons of butter. Add the flour and whisk continuously to create a roux. Gradually pour in the whole milk, whisking constantly to avoid lumps. Continue cooking until the mixture thickens.

Step 3: Add Cheeses and Dijon Mustard Reduce the heat to low and add the shredded cheddar and grated Parmesan cheeses. Stir until the cheeses are melted and the sauce is smooth. Incorporate the Dijon mustard, salt, and black pepper. Adjust seasoning to taste.

Step 4: Arrange Asparagus in a Baking Dish Place the blanched asparagus in a greased baking dish, arranging them in an even layer.

Step 5: Pour Cheese Sauce Over Asparagus Pour the velvety cheese sauce evenly over the asparagus, ensuring each spear is coated in the rich mixture.

Step 6: Prepare the Breadcrumb Topping In a small bowl, combine the breadcrumbs with the melted butter. Mix until the breadcrumbs are evenly coated.

Step 7: Top with Breadcrumbs Sprinkle the breadcrumb mixture over the cheese-coated asparagus, creating a generous and golden topping.

Step 8: Bake to Perfection Bake in the preheated oven for 20-25 minutes or until the top is golden brown, and the cheese sauce is bubbling.

Step 9: Serve and Enjoy Remove the casserole from the oven and let it cool slightly before serving. Each bite is a delectable combination of crisp asparagus, creamy cheese sauce, and crunchy breadcrumbs.



Experiment with different cheese combinations to customize the flavor profile of your casserole. Gouda, Swiss, or Monterey Jack can be excellent additions or substitutes for a unique twist.



Fresh Asparagus: Opt for fresh, crisp asparagus for the best texture in your casserole.

Even Coating: Ensure each asparagus spear is coated evenly with the cheese sauce for a consistent and flavorful dish.

Golden Breadcrumbs: Keep an eye on the casserole in the oven to achieve a perfectly golden breadcrumb topping without overbaking.
