Cauliflower, Pasta And Cheese Gratin - cooking recipe

Ingredients

8 cups water
6 cups cauliflower florets (about 1-1/2 pounds)
3/4 teaspoon salt, divided
8 ounces uncooked small shell pasta (any small pasta will do)
1/4 cup all-purpose flour
3 cups 1% low-fat milk
2 teaspoons fresh thyme, chopped or 3/4 teaspoon dried thyme
3 garlic cloves, crushed
1 cup reduced-fat sharp cheddar cheese, shredded
1/2 cup fresh parmesan cheese, grated
3/4 cup green onion, finely chopped
2 teaspoons Dijon mustard
1/4 teaspoon black pepper
2 slices white bread
2 teaspoons butter, melted

Preparation

Preheat oven to 400\u00b0F.
Bring water to a boil in a large saucepan; add cauliflower and 1/2 teaspoon salt to boiling water, and cook 4 minutes or until tender. Remove cauliflower with a slotted spoon, reserving cooking liquid; set cauliflower aside. Bring cooking liquid to a rolling boil. Add pasta, and cook 7 minutes or until al dente; drain and set aside.
Lightly spoon flour into a dry measuring cup, and level with a knife. Combine flour and milk in a saucepan, stirring well with a whisk. Stir in thyme and garlic; cook over medium heat until thick (about 8 minutes), stirring constantly. Remove from heat; stir in 1/4 teaspoon salt, cheeses, onions, mustard, and pepper.
Combine cauliflower, pasta, and cheese sauce in a large bowl. Spoon the cauliflower mixture into a 13x9-inch baking dish. Place bread in food processor; pulse 10 times or until coarse crumbs form to measure 1 cup. Combine breadcrumbs with butter; sprinkle evenly over cauliflower mixture. Bake 400\u00b0F for 20 minutes or until lightly browned.
