Zesty Broccoli Casserole - cooking recipe

Ingredients

3 (10 ounce) packages frozen broccoli florets, thawed
cooking spray (I use olive oil in a Misto)
1 1/2 cups milk
2 1/2 tablespoons all-purpose flour
1/2 teaspoon salt
1/4 teaspoon fresh ground black pepper
3/4 cup shredded sharp cheddar cheese
1/2 cup reduced-fat cream cheese, softened
1 cup mayonnaise
3/4 cup chopped onion (about 1/2 medium)
3/4 cup panko breadcrumbs (Japanese breadcrumbs)
1 tablespoon butter, melted

Preparation

Arrange broccoli in an even layer in an 11 x 7-inch baking dish coated with cooking spray; set aside.
Combine milk, flour, salt, and pepper in a large saucepan over medium-high heat; bring to a boil. Cook 1 minute or until thick, stirring constantly. Remove from heat. Add cheddar and cream cheeses; stir until smooth. Stir in mayonnaise and onion. Spoon cheese mixture evenly over broccoli.
Place panko in a small bowl. Drizzle with butter, and toss. Sprinkle breadcrumb mixture evenly over cheese mixture. Lightly spray breadcrumb layer with cooking spray. Bake at 375\u00b0 for 25 minutes or until mixture begins to bubble and breadcrumbs brown.
