Tuna Noodle Casserole

An ol’ school favorite also known as Tuna Rockefeller. This casserole is plenty healthy with the protein of tuna and vitamin-rich spinach, combined with the creamy and crunchy goodness of a “Mac & Cheese”-like texture.

Cook time: 50 minutes
Total time: 1 hour and 10 minutes


Ingredients

  • Cooking spray
  • 6 ounces egg noodles
  • 3 tablespoons butter 
  • 1 tablespoon extra-virgin olive oil
  • 1 cup finely chopped onion 
  • ½ cup finely chopped celery 
  • 10 ounces mushrooms, sliced 
  • 3 tablespoons dry sherry 
  • 2 teaspoons reduced-sodium soy sauce 
  • ½ teaspoon kosher salt 
  • ½ teaspoon ground pepper 
  • ¼ cup all-purpose flour 
  • 2 cups low-sodium chicken broth, divided 
  • 1 cup reduced-fat milk 
  • 2 teaspoons Dijon mustard 
  • 2 5-ounce cans chunk light tuna in olive oil, drained
  • 10 cups baby spinach or 4 cups frozen chopped spinach (thawed)
  • 1 cup coarse fresh breadcrumbs (see Tips), preferably whole-wheat
  • ¾ cup grated sharp cheddar cheese 
  • 1 tablespoon extra-virgin olive oil

Directions

  1. Preheat oven to 375°F. Coat a 9-by-13-inch pan (or similar-size 3-quart baking dish) with cooking spray.
  2. Cook noodles according to package instructions. Drain and set aside. Dry the pot.
  3. Heat butter and 1 tablespoon oil in the pot over medium heat until the butter is melted. Add onion and celery; cook, stirring occasionally, until soft, about 5 minutes. Add mushrooms and cook, stirring occasionally, until their liquid evaporates, 3 to 5 minutes. 
  4. Stir in sherry, soy sauce, salt, and pepper and cook until almost all the liquid has evaporated, 2 to 4 minutes more. Sprinkle flour over the vegetables, stir to coat and cook for 30 seconds.
  5. Increase heat to high, add ½ cup broth and stir until starting to boil. Add the remaining 1½ cups broth, milk, and mustard; bring to a boil and cook, stirring often, until the sauce thickens, about 2 minutes.
  6. Add tuna, spinach, and the noodles; cook, gently stirring often, until heated through, about 3 minutes. Transfer to the prepared baking dish.
  7. Combine breadcrumbs and cheese in a small bowl. Stir in 1 tablespoon oil and sprinkle over the casserole.
  8. Bake until the sauce is bubbling and the topping is golden brown, 20 to 25 minutes.
