Ingredients

  • 2 teaspoons olive oil
  • 1 1/2 cups finely chopped onion (about 1 medium)
  • 1 (12-ounce) package gluten-free brown rice penne (such as Tinkyada)
  • 1/4 cup cornstarch
  • 4 cups 1% low-fat milk, divided
  • 3/4 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon grated whole nutmeg
  • 1 cup (4 ounces) shredded reduced-fat sharp cheddar cheese
  • 1 cup (4 ounces) shredded part-skim mozzarella cheese
  • Cooking spray
  • 1/2 cup (2 ounces) grated fresh Parmesan cheese
  • 1/4 cup panko-style breadcrumbs (such as Kinnikinnick)

Method

  • Preheat oven to 375°.
  • Heat oil in a medium Dutch oven over medium heat. Add onion; cook 5 minutes or until tender, stirring often.
  • While onion cooks, cook pasta according to package directions, omitting salt and fat. Drain.
  • Combine cornstarch and 1/2 cup milk in a small bowl. Add remaining 3 1/2 cups milk to onion; bring to a boil. Gradually stir in cornstarch mixture. Cook 2 minutes or until sauce thickens, stirring constantly. Remove from heat, and stir in salt, pepper, and nutmeg. Add cheddar and mozzarella cheeses, stirring with a whisk until cheeses melt. Stir in pasta. Pour pasta mixture evenly into 6 (2-cup) gratin dishes or ramekins coated with cooking spray.
  • Combine Parmesan cheese and breadcrumbs; sprinkle over pasta mixture. Bake at 375° for 30 minutes or until sauce is bubbly and top is brown.
