Mac and Cheese

Cook pasta as package directs. Meanwhile, mix flour, onion powder, salt and pepper in medium saucepan. Whisk in milk until smooth. Cook over medium-high heat, stirring constantly, until mixture boils and thickens, about 5 minutes; remove from heat.

Heat broiler. Coat a 1 1/2- qt shallow baking dish with nonstick cooking spray.

Stir puréed carrots and 1/2 cup Cheddar into white sauce until cheese is melted. Drain pasta and return to pot; stir in sauce. Spoon half the pasta into prepared dish; sprinkle with 1/2 cup Cheddar. Top with remaining pasta, cheese and the crumbs. Broil 4 to 6 in. from heat about 6 to 7 minutes until top is lightly browned.
