Ingredients You’ll Need

For the casserole

2 pounds fresh asparagus, trimmed and cut into 2-inch pieces
2 tablespoons butter
1 small onion, finely chopped
2 garlic cloves, minced
2 tablespoons all-purpose flour
1 cup milk (whole or 2%)
1 cup heavy cream
1 teaspoon salt
½ teaspoon black pepper
½ teaspoon paprika (optional for flavor and color)
1 cup shredded mozzarella cheese
1 cup shredded sharp cheddar cheese

For the topping

1 cup buttery cracker crumbs (like Ritz) or breadcrumbs
2 tablespoons melted butter
¼ cup grated Parmesan cheese

Step-by-Step Instructions

Step 1: Prepare the Asparagus

Start by washing the asparagus and trimming off the tough ends. Cut each spear into bite-sized pieces—around 2 inches.

Bring a pot of salted water to a boil. Add the asparagus and let it blanch for 2–3 minutes, just until it turns bright green. Drain immediately and run cold water over it to stop the cooking.
This step helps keep the asparagus crisp, fresh, and vibrant in the casserole.

Step 2: Make the Creamy Cheese Sauce

In a large skillet, melt the butter over medium heat. Add the chopped onion and cook until soft and translucent, about 3–4 minutes.
Stir in the minced garlic and cook for another 30 seconds.

Sprinkle in the flour and whisk continuously to form a smooth paste—this is your roux. Cook for 1 minute to remove any raw flour taste.

Gradually pour in the milk and heavy cream, whisking constantly. The mixture will start to thicken into a silky sauce.

Season with salt, pepper, and paprika.

Once thickened, remove from heat and stir in the cheddar and mozzarella until fully melted and smooth.
You now have a rich, creamy cheese sauce that will coat the asparagus perfectly.
