Ingredients
For the Casserole:
- 1 pound fresh asparagus, trimmed and cut into 2-inch pieces
- 2 tablespoons butter
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 2 tablespoons all-purpose flour
- 1 cup milk (whole milk recommended for creaminess)
- ½ cup heavy cream (optional, for extra richness)
- 1 teaspoon Dijon mustard
- Salt and pepper to taste
- 1 cup shredded cheddar cheese (or your favorite cheese blend)
- ½ cup grated Parmesan cheese
For the Topping:
- ½ cup panko breadcrumbs
- 2 tablespoons melted butter
- ¼ cup grated Parmesan cheese
Step-by-Step Method
1. Prepare the Asparagus
Start by washing the asparagus thoroughly. Trim the woody ends and cut the spears into 2-inch pieces. Blanch them in boiling water for 2–3 minutes until they turn bright green but remain slightly crisp. Drain and immediately plunge them into ice water to stop the cooking process. Set aside.
Tip: Blanching keeps asparagus tender yet firm, preventing it from turning mushy in the casserole.
2. Make the Creamy Cheese Sauce
- In a medium saucepan, melt 2 tablespoons of butter over medium heat.
- Add the chopped onion and sauté for 3–4 minutes until soft and translucent.
- Stir in the minced garlic and cook for 30 seconds until fragrant.
- Sprinkle the flour over the onion and garlic mixture. Stir constantly for 1–2 minutes to form a roux.
- Gradually whisk in the milk and heavy cream until smooth. Cook for 3–5 minutes, stirring, until the sauce thickens.
- Stir in Dijon mustard, salt, and pepper.
- Remove from heat and add the cheddar and Parmesan cheeses. Stir until melted and creamy.
Tip: If the sauce is too thick, add a splash more milk. If too thin, cook a bit longer to thicken.
3. Assemble the Casserole
- Preheat your oven to 375°F (190°C).
- In a greased 9×13-inch baking dish, arrange the blanched asparagus evenly.
- Pour the creamy cheese sauce over the asparagus, ensuring all pieces are coated.
- Gently stir to combine but avoid breaking the asparagus.
4. Prepare the Topping
- In a small bowl, mix the panko breadcrumbs, melted butter, and grated Parmesan.
- Sprinkle this mixture evenly over the casserole.
Tip: For extra flavor, add a pinch of paprika or garlic powder to the topping.
5. Bake the Casserole
- Place the casserole in the preheated oven.
- Bake uncovered for 20–25 minutes until the topping is golden brown and the sauce is bubbly.
- Let the casserole rest for 5 minutes before serving to set the sauce.
Serving Suggestions
- Pair with roasted chicken, turkey, or grilled fish for a complete meal.
- Sprinkle extra fresh herbs like parsley or chives on top for added color and flavor.
- Serve as a hearty vegetarian main by adding cooked quinoa or rice underneath the casserole.
Tips for Perfection
- Cheese Choice: Cheddar gives a sharp flavor, while Gruyère adds a nutty note. Mixing cheeses works beautifully.
- Asparagus Size: Thicker spears work best as they hold their shape during baking.
- Make Ahead: Assemble the casserole a few hours before baking. Keep refrigerated and bake when ready.
