Bacon Macaroni and Cheese

This is a great grown-up version of mac 'n cheese: it satisfies your comfort food craving, while still being a respectable gourmet meal.

• 3 1/4 teaspoons salt, divided
• 12 ounces whole wheat penne pasta
• 4 teaspoons all-purpose flour
• 1 1/2 cups skim milk, divided
• 2 cups finely shredded reduced fat sharp cheddar cheese, divided
• 1/4 cup sliced red onions
• 1 teaspoon hot sauce
• 1/4 teaspoon pepper
• 4 slices turkey bacon, cooked and crumbled
• Cooking spray

Preheat the oven to 350°.

Bring 6 quarts water and 1 tablespoon salt to a boil. Add pasta; cook 8 minutes or until al dente; drain.

Combine flour and 1/2 cup milk in a saucepan over medium heat. Gradually add 1 cup milk; bring to a boil. Cook 1 minute, stirring constantly. Remove from heat; let stand 4 minutes or until it cools to 155°. Stir in 1 1/2 cups cheese. Add 1/4 teaspoon salt, onions, hot sauce, pepper, and bacon; stir. Add pasta; toss. Spoon into a 2-quart oven-safe dish coated with cooking spray; top with 1/2 cup cheese. Bake 10-15 minutes.
