Ingredients
3 tablespoons unsalted butter, divided
½ cup panko breadcrumbs, preferably whole-wheat
3 pounds asparagus, trimmed and cut into 2-inch pieces
1 tablespoon finely chopped garlic
2 tablespoons all-purpose flour
2 cups whole milk
5 ounces cream cheese
½ cup shredded part-skimmed mozzarella cheese
1 teaspoon salt
Instructions
Preheat over to 450 degrees F. Put a large pot of water on to boul. Set a large bowl of ice water near the stove.
Melt 1 tablespoon butter in a small bowl in the microwave, about 30 seconds. Stir in panko; set aside.
Cook asparagus in the boiling water until bright green, about 1 minute. Drain and transfer to the ice bath. Let cool for 5 minutes, then drain and pat dry. Arrange the asparagus in a 9-by-13-inch baking dish.
Heat the pot over medium-high heat. Add the remaining 2 tablespoons butter and stir until melted. Add garlic and cook, stirring, until fragrant, about 1 minute. Add flour and cook, stirring for 30 seconds. Gradually whisk in milk. Bring to a boil, whisking constantly. Continue cooking and whisking until the mixture thickens, about 5 minutes. Remove from heat. Stir in cream cheese, mozzarella and salt. Pour the cheese sauce over the asparagus and stir to coat.
Sprinkle the reserved panko mixture on top. Bake until the asparagus is tender, 12 to 15 minutes.
