  • 12 ounces egg noodles
  • 4 tablespoons unsalted butter
  • 1/2 medium onion diced
  • 2 cloves garlic minced
  • 4 tablespoon all-purpose flour
  • 2 cups chicken broth
  • 1 1/2 cups milk
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon paprika
  • 2 cups frozen peas
  • 12 ounces canned albacore tuna drained
  • 2 cups shredded sharp cheddar cheese divided

Breadcrumb Topping

  • 1 cup panko bread crumbs
  • 2 tablespoons unsalted butter melted


  • Preheat oven to 350 degrees.
  • Cook egg noodles according to package directions for al dente pasta. Drain, pour noodles into 9x13 pan, and set aside. 
  • In a saucepan over medium heat, add butter. Once hot and melted, add diced onions. Cook until onions begin to brown and turn translucent. Add garlic and flour, then cook for 1 additional minute. 
  • Add chicken broth and milk, whisking until incorporated. Bring to a simmer and cook until sauce has thickened slightly, about 3 to 4 minutes. 
  • Remove from heat and add salt, pepper, paprika, peas, tuna, and half of cheese, stirring to combine. Pour mixture over noodles and toss to coat.
  • Sprinkle remaining half of cheese on top of casserole. 
  • In a separate bowl, combine bread crumbs and melted butter. Sprinkle evenly over casserole. 
  • Bake uncovered for 15-18 minutes, or until casserole is heated through. Optionally, broil for 2 minutes to brown crust on top.
