What to Gather for Asparagus Casserole

Gathering the right ingredients is essential for making a delicious Asparagus Casserole. Each ingredient plays a critical role in contributing to the overall flavor and texture of the dish. From the tender asparagus to the creamy sauce, these components work harmoniously to create a delightful meal. Let’s explore the key players that make this casserole so special.
- 2 lbs of Asparagus: Fresh and trimmed, asparagus adds a lovely green color and nutritious boost. Choose firm, bright green spears for the best flavor.
- 4 Tbsp Unsalted Butter: Used for both the sauce and greasing the dish, butter provides richness and flavor.
- 2 1/2 Tbsp All-Purpose Flour: This ingredient helps to thicken the sauce, creating a creamy consistency that coats the asparagus beautifully.
- 2 cups Half and Half: This mixture gives the sauce a creamy texture; you can also use equal parts milk and heavy cream for a richer flavor.
- 2 tsp Garlic Salt: Adds a savory depth to the dish.
- 1/4 tsp Black Pepper: A pinch of black pepper enhances all the other flavors.
- 1 cup Parmesan Cheese: Divided into two portions, it’s mixed into the sauce and used as a topping, adding a lovely cheesy flavor.
- 1/2 cup Panko Bread Crumbs: These breadcrumbs create a delightful crunch on top of the casserole.
Step by Step Guide for Asparagus Casserole

Making this Asparagus Casserole is a straightforward process that results in a dish that’s impressive yet comforting. Here’s how to bring it all together in a few simple steps.
- Preheat your oven to 400˚F and position the rack in the center. This step is crucial for ensuring even cooking.
- Prepare a 9×13 casserole dish by greasing it with a bit of butter. This prevents the asparagus from sticking and allows for easy serving.
- Arrange the trimmed asparagus in the prepared dish. Make sure they’re packed down evenly for a flat surface. This not only looks appealing but ensures even cooking.
- In a medium saucepan over medium heat, melt 3 Tbsp of butter. Once melted, add 2 1/2 Tbsp of flour while whisking constantly for about 3 minutes, until the mixture begins to turn a light golden color. This step creates a roux, which will thicken your sauce.
- Gradually whisk in 2 cups of half and half, along with 2 tsp of garlic salt and 1/4 tsp of black pepper. Continue whisking until the sauce thickens slightly; then remove it from the heat.
- Stir in 1/2 cup of Parmesan cheese until it’s melted and fully incorporated into the sauce. This adds a creamy, cheesy flavor that’s divine.
- Pour the sauce evenly over the arranged asparagus, leaving a little space on the sides of the dish for bubbling.
- Bake the casserole uncovered in the preheated oven for about 15 to 18 minutes or until the asparagus reaches your desired tenderness. Keep an eye on it; you want it just tender but not mushy!
- While the casserole bakes, prepare the breadcrumb topping. In a small mixing bowl, melt the remaining 1 Tbsp of butter. Add 1/2 cup of Panko bread crumbs and stir until they’re evenly moistened. Then mix in the remaining 1/2 cup of Parmesan cheese.
- Halfway through baking, carefully sprinkle the breadcrumb mixture evenly over the casserole. This adds a delightful crunch and golden color once baked.
- Once the asparagus is cooked to your liking, switch your oven to broil for about 2 to 3 minutes or until the breadcrumbs turn golden brown. Watch it closely to prevent burning!
- Remove the casserole from the oven, let it cool slightly, then serve warm. Enjoy the smiles as you serve this wonderful dish!
Things Worth Knowing
